|
|
- EMM fix (Hans)
|
|
- first round vm86plus (emumodule) (Hans)
|
|
96/10/20 ver. 0.64.0.3
|
|
- Priv off/on patches
|
|
- mfs.c patch to allow PRN called from mfs drives
|
|
- mouse.c modifed calls that reflect mouse visibility and
|
|
changed vectoring mouse interrupts to the actual interrupt
|
|
(thanks to Josef Pavlik)
|
|
- X.c added back mouse mickeys - WP5.1 mouse works now using
|
|
internal driver, but not WPs ROF. Also forced mouse reset
|
|
on DOSEmu boot if internal mouse being used.
|
|
(thanks to Bernd Paysan <paysan@informatik.tu-muenchen.de>)
|
|
- Alberto's patches to configure scripts for SBEMU.
|
|
- Hans' patches for running on Linux 2.1.5+
|
|
96/09/24 ver. 0.64.0.2 - From Hans, SMP, emumodule, insmod and some minor DPMI-stuff
|
|
96/09/23 ver. 0.64.0.1 - JES took over some valuable patches from 0.63
|
|
96/09/18 23:06:34 From : JES - Allow compiling without X support --without-x
|
|
96/08/30 01:21:30 From: Eric -- Some more Bugfixes, and a little video cleanup practice
|
|
96/08/07 13:56:38 From : Rainer - Video / Keyboard / Misc cleanup
|
|
* added runtime MITSHM detection
|
|
* fixed a problem with mouse initalisation
|
|
* mfs.c: fixed find_first error code if directory doesn't exist
|
|
96/08/02 18:45:49 From Alberto - Fix PIC bug even w/o emumodule & leave for vacations
|
|
96/08/01 22:39:10 From : JES - Minor changes to pic.[ch]
|
|
- Not sure if these make a difference, but since I'm no C guru, it looked
|
|
like some variable (pic_sys_time) were defined twice? At least it still
|
|
works looking this way ;).
|
|
96/07/31 19:57:40 From Alberto - Make debug flag working again & other fixes
|
|
96/07/31 18:29:09 From : JES - More IPX fixing and a Video WorkAround
|
|
- After all I went through to learn _not_ to call IPX functions
|
|
directly... I turn around and do it again ;-(. Always call IPXCallRel().
|
|
96/07/31 13:57:15 From : JES - Fix IPX again ;(
|
|
96/07/31 12:03:14 From : JES - The Real Patch(tm) to bring IPX watchdog into DOSEmu
|
|
- With many thanks to Tim Bird and JL, here is a patch to get
|
|
asynchronos events happening under DOSEmu. This will make DOSEmu
|
|
nolonger dependent on the wdogfix.com TSR. The problem before was
|
|
making a stack returnable via retf. Also added is an ESR callback
|
|
which may give slight IPX speed inprovements (may not), but
|
|
prepares DOSEmu for more IPX development ;).
|
|
96/07/29 21:33:55 From Alberto - Fixed sig11 in leavedos() and cleaned some warnings
|
|
|
|
96/09/15 ******** Release 0.64.0 - Made from 0.63.50

|
|
96/07/21 00:51:37 From Alberto - patches to serial code to avoid reentrancy
|
|
problems - Changes to tracing code in ports.c and dpmi.c - Some spelling
|
|
and small bug fixes
|
|
96/07/19 22:34:50 From : kan@dcit.cz - Fixes to parsing and Dr? regs.
|
|
1) parse_config() used to check the wrong id in order to find out whether
|
|
the user is allowed to have dangerous options in the configfile.
|
|
Hum.. it looks like my own bug...
|
|
(someone already fixed the same thing in parse_dosemu_users())
|
|
2) At least one program (I think it was a game--Winter Olympic Games perhaps)
|
|
plays with dr? registers (trying to avoid being debugged?). This problem
|
|
made me add some handling for mov dr??, ?? to vm86_GP_fault and make the
|
|
type of org_eip correct (actually, I did it in the opposite order <smile>)
|
|
96/07/10 11:26:50 From Hans: Dosdebug goes DPMI (+some minor DPMI-fixes)
|
|
96/07/07 16:13:11 From : JES - Allow stdin to be non-tty
|
|
- NO this is not the do-all-end-all to allow remote control access of DOSEmu.
|
|
It is only a stop gap to allow some next steps in testing.
|
|
96/07/07 13:27:10 From : JES - Replacment to WatchDog.com TSR for IPX
|
|
96/07/07 13:20:14 Cleanup and doc updates

|
|
After much effort and many thanks to Kang-Lee I can understand him when he says:
|
|
"Well, this patch really deserves the award of most_complicated_patch_story. :-)"
|
|
Thanks Kang-Lee ;-)
|
|
96/07/04 21:56:58 From Alberto: some goodies for DPMI, DJGPP, GUSPNP, port fixes, e.t.c.

|
|
|
|
* Cleaned up mainy tiny things regarding font loading, screen
|
|
resizing, and updating bios variables. Now everything under X
|
|
should work under X except font loading and it punts that.
|
|
|
|
* Fixed a tiny bug where in emu-i386 where EIP was stored in a
|
|
character. Only important to dosdebug
|
|
All fixes against 0.63.36

96/06/08 12:28:52 From Uwe : Port Access for (L)Users
|
|
Hallo,
|
|
|
|
the patch I posted yesterday was "cut and dropped" in my editor. That way,
|
|
parts get mangled. And I didn't apply it to a clean tree, so an error
|
|
slipped by. Here is the patch against 0.63.1.30:
|
|
96/06/07 20:12:36 From JES : Reduce HMASIZE by 16 bytes as suggested by HJ
|
|
96/06/07 17:11:37 From Hans: emumodule & restore_i387; patches from Bernd
|
|
From Bernd Paysan <bernd@informatik.tu-muenchen.de>:
|
|
- The timer initialization in src/base/init/init.c reduced to stay
|
|
in 32 bit integer arithmetic.
|
|
- The mouse handler fakes an interrupt and pusha on the real mode stack,
|
|
regardless if the program is in rm or pm. I added a fake_pm_int().
|
|
- The X_SELECTION isn't well separated from X_MOUSE. I tried to do it
|
|
(src/env/video/X.c).
|
|
|
|
96/06/03 12:39:57 From Hans: Fix silly vm86.h include loop (oh yeah, it was my fault).
|
|
96/06/02 15:58:42 From Hans: more LDT-access rights if running root, back out old, vm86.h hack
|

96/05/28 21:33:31 From Hans: forbid kerneld to unload emumodule, vm86.h missing fix.

|
96/04/26 17:11:28 From : Avery Pennarun - dosemu 0.63.1.8 X bugs (and fix)
|
|
Avery Pennarun <apenwarr@foxnet.net>
|
|
It changes env/video/X.c to use unsigned chars instead of chars for screen
|
|
cells. Due to certain tests in the code, any character >128 (such as
|
|
line-drawing characters) would _always_ act as if that line had changed
|
|
since the last refresh. So, in full-screen applications like Borland C++,
|
|
the flicker (and related CPU usage) was horrible.
|
|
|
|
BTW, why on earth is the "byte" typedef a signed char?
|
|
|
|
Have fun.
|
|

|
|
96/03/16 16:14:36 From : JES - temporarily turn of port array call of portss.c
|
|
- From some timing investigations it has been discovered that the
|
|
portss.c array calling code seems to be considerable slower
|
|
in it's present state. To that end as an interim measure, we
|
|
will turn it off and use the older single case statement.
|
|
96/03/13 19:50:26 From : Alberto Vignani - Change non-existant port read to 0xff again

|
|
- If 0'd out the VGA_EMU_FAULT() because it is not defined
|
|
96/03/07 23:39:37 From: John Kohl: turn on X_GRAPHICS for NetBSD
|
|
- turn on X_GRAPHICS support for NetBSD, it seems to work well enough
|

|
|
96/03/07 19:10:38 From : John Kohl - NetBSD diffs for 0.63.1.2
|
|
From: John Kohl <jtk@kolvir.arlington.ma.us>
|
|
- Anyway, there's a system bug tickled by these changes on NetBSD but it
|
|
pretty much works.
|
|
- I haven't tried X graphics support yet, but I made
|
|
it easy to configure in or out now.
|
|
- I think I found a bug with KERNEL_LDTALIAS in the dpmi code, plus a
|
|
questionable missing () stuff there. Look inside dpmi.c
|
|
Thanks!
|
|

96/03/05 22:20:22 From : JES - Up version to 0.63.1.2
|
|
96/03/05 22:02:23 From : (Alberto) a.vignani@crf.it - Change cpu.c ports to size short
|
|
I was tracing a DOS program accessing a peripheral card and found dosemu
|
|
tried to access ports > 64k. After looking at the generated assembly, I
|
|
changed 'int' to 'short' for all port addresses in cpu.c.

|
- From Hans Lermen (and Kevin Buhr): Fix for timerlock-bug
|
|
|
|
This includes the patch from Kevin Buhr (good work),
|
|
plus some fixes to make hardware-IRQs work (Sillyint),
|
|
plus some other pic fixes (correct now, but wasn't the reason for the lock)
|
|
plus THE (one line) fix for the _real_ bug:
|
|
|
|
Once again we messed up with VIF flag, hence letting ints pass
|
|
through. even if CLI was active.
|
|
This apparently was one 'bug-catcher' we left back during the
|
|
the great hunt for 'the bug of bugs' some month ago.
|
|
(Hmm... I say 'we', but very well may be that it was 'me')
|
|
|
|
I also introduced a
|
|
#define USE_UNIX_TIME_FOR_INT1A_AH0
|
|
which should be defined at top of dosemu/int.c to get the 'old' code,
|
|
which does not use the BIOS 40:6c timer, but got the time from Linux
|
|
and overwrites 40:6c.
|
|
Currently it is not defined, so INT1A AH=0 gets time from 40:6c,
|
|
however, if somone gets 'timerlocks' again (which I don't hope),
|
|
then try witch defineing USE_UNIX_TIME_FOR_INT1A_AH0 and report to the
|
|
team.
|
|

Hi,
|
|
Having some dos stuff which I wanted to run, I decided that it was
|
|
time to update my dosemu. Unfortunately, I still only run a mono HGA
|
|
card so dosemu-0.60.3 was not a stunning success. Anyway, I dug into
|
|
the sources to the extent which was necessary to get it to work with
|
|
my HGA card and the resulting patches are attached to the end of this
|
|
message. The patches also improve the functionality in that dosemu
|
|
now does something more sensible with the cursor.
|
|
|
|
Not having followed the development of dosemu closely, I don't
|
|
claim that these patches represent the correct way to solve the
|
|
problems, only that they work for me under admittedly limited testing.
|
|
|
|
The patches also apply cleanly to dosemu-0.60.4.3 (apart from a
|
|
trivial Makefile change) and seem to compile o.k., but I haven't
|
|
checked the result because I don't want to bother with modules yet.
|
|
|

|
|
|
|
- From: "Pavel Kankovsky" <KAN@frode.dcit.cz>
|
|
These my patches are against 0.60.3 (but they seem to still be
|
|
usable in 0.61.00 from what I have seen at the first glance).
|
|
Here is some description only (usable as ChangeLog entries, I hope),
|
|
diffs themselves are enclosed as attached files (dosemu[0-3].diff).
|
|
|
|
Patch 0 fixes 3 things in mfs.c:
|
|
- Mktime() uses tm_isdst value (unlike stated in the original source code)
|
|
leaving it unset causes random mtime shifts by one hour and has funny
|
|
effects esp. when running make, value -1 (which meaning is "figure out
|
|
the proper value yourself" :> ) seems to be the best one for me.
|
|
- Hlist stack management was quite 'kludge-o-matic' in the original code
|
|
and caused problems with Quattro Pro 5.0 installation program which
|
|
starts a directory search, does NOT finish it and spawns unzip program
|
|
that starts another directory search, and upon unzip's exit, both lists
|
|
were popped, making the installation die eventually.
|
|
I rewrote findfirst/next and hlist_push/pop to allow this case and
|
|
do it all in a bit cleaner way.
|
|
- Findfirst returns FILE_NOT_FOUND no more because original Dos returns
|
|
this value only for EMPTY directories (even no ., .., volume label!),
|
|
so NO_MORE_FILES is more convenient in most cases (esp. for Volkov
|
|
Commander -- Norton Cmdr. alike -- that used to complain "Can't read
|
|
volume in drive X:" every time it got FILE_NOT_FOUND for findfirst)
|
|
|
|
Patch 1 brings some improvement I made in dosdbg.c and its counterpart
|
|
dyndeb.c to help myself when examining PIC working. The original code
|
|
does not accept debug levels (as Dosemu command line options do). Now
|
|
you can do something like "dosdbg 3r" when Dos boots and reduce the
|
|
debugging log by cca 300 kilobytes. :-)
|
|
|
|
Patch 2 makes Dosemu safer as it does not allow ordinary users to do
|
|
"dos -F ..." with dangerous (e.g. direct disk access) settings in their
|
|
configfiles.
|
|
|
|
Patch 3 modifies keyboard driver finalization so as to let keyboard leds
|
|
follow in-kernel num/caps/scroll-lock flags again. (I was trying to make
|
|
it save led-function setting and restore it later but the kernel does not
|
|
seem to provide a straight-forward way of doing it. Bad luck.)
|
|
|
|
I hope it will help make Dosemu better Dos than Dos! :-)
|

|
|
|
|
- Patches to XMS for better himem compatibility
|
|
|
|
Wed Oct 11 22:28:05 1995 John Kohl <jtk@pattern.arlington.ma.us>
|
|
|
|
* Update for latest NetBSD stuff
|
|
|
|
Wed Sep 27 1995
|
|
|
|
- Included many patches to get NetBSD back on track.
|
|
- Added in 2 patches for debugger and other en-Hans-ments :-)
|
|
|
|
Tue Sep 12 1995
|
|
|
|
- Added first layer of DMA and SoundBlaster code oringinally
|
|
contributed by Joel Weber (age 15), then put into the
|
|
distribution by Alistair.
|
|
|
|
Sat Sep 09 1995
|
|
|
|
- Added FOSSIL internal support by
|
|
pasi@forum.nullnet.fi (Pasi Eronen)
|
|
- Added X enhancments and -O option by
|
|
Uwe Bonnes bon@elektron.ikp.physik.th-darmstadt.de and Pasi.
|
|
- Hans' latest syscallmgr updates.
|
|
|
|
Thu Jul 28 1995
|
|
|
|
- Release DOSEMU-0.60.4.tgz
|
|
- Hans' patch to dpmi.c
|
|
- Added CLTS from rde@tadpole.co.uk (Richard Evans)
|
|
- Added .ini extensions from Jon
|
|
- From Snow Cat
|
|
2) pic/pic.c has some assembler code that doesn't work with -O3 because it's
|
|
using global labels that get expanded more than once. Fixing it to use local
|
|
labels solves the problem.
|
|
|
|
3) mfs/mfs.c doesn't handle "commit file" and "flush all disk buffers". It
|
|
causes AH=68H/int 21H to return an error code that confuses database programs.
|
|
I changed COMMIT_FILE to do fsync() and FLUSH_ALL_BUFFERS to do nothing and
|
|
return success (because sync()ing every time DOS wants to flush buffers makes
|
|
too much noise).
|
|
.... and some other patches too.
|
|
|
|
- Mfs patch from Andi.
|
|
- Mouse patches from beck@informatik.hu-berlin.de (Michael Beck)
|
|
- Patches for UID settings by Steven P. Crain
|
|
|
|
Wed Jun 28 1995
|
|
|
|
- Release DOSEMU-0.60.3.tgz
|
|
|
|
From Hans :
|
|
This is a summary of my changes since dosemu0.60.2:
|
|
|
|
- Upgraded syscallmgr/insmod to modutils-1.2.8
|
|
(full insmod-tree is in insmod-1.2.8-HACKER_TOOL.tar.gz)
|
|
Now can (mix) load a.out- or ELF- modules into
|
|
a.out- or ELF- kernels.
|
|
- New LDT support for emumodule, now can access the *real* LDT
|
|
from dosemu user space. How it works can be seen in ldttest.c
|
|
- Made emumod ELF compilable
|
|
( patch from Rick Sladkey <jrs@world.std.com> )
|
|
- Took over some changes to vm86() from Linux 1.2.11 and 1.3.3
|
|
into emumodule. Also now doing full verify_area on all accessed
|
|
user space in emumodules' vm86() (USE_VM86_STACKVERIFY).
|
|
This fixes some odd DOS register messups.
|
|
- Fixed wrong flag handling in bios.S for INT10 .. INT1B
|
|
(some of them should IRET).
|
|
- Improved return to DOS-space from dosemu redirected INTs
|
|
int dosemu/int.c function do_int().
|
|
(did respawn to dosemu immediately, so leaving the DOSapp
|
|
no chance to react).
|
|
- Fixed interruption of DOS space when interrupts were disabled.
|
|
( check for VIF at entry of pic's run_irqs() ).
|
|
This fixes the main trouble together with sillyint (exception 6 bug).
|
|
JES did the rest by finding this damned WRITE_FLAGS bug and
|
|
fixing various VIF/IF handling.
|
|
- Now dosemu will do register dump if -g debugflag is set and
|
|
if killed via SIGHUP. So we can see were the DOSapp is hanging.
|
|
- Varous fixing for sillyint (SIG), so it now complies with the
|
|
new pic-handling.
|
|
- Fix startup recognition of loaded emumodule. Now it will exit
|
|
with error if no module is loaded and REQUIRES_EMUMODULE is set.
|
|
- Made dosemu/sigsegv.c real-mode-386-compatible and fixed wrong
|
|
prefix handling (ES,DS,GS,FS,REP).
|
|
Moved some remaining 'fprintf(stderr)' to 'i_printf()'
|
|
- Fixed overload condition resulting in DOS internal stack overflow.
|
|
(<ESC> bug while using SLANG terminal). This is done by monitoring
|
|
the difference between pic_sys_time and pic_dos_time and avoiding
|
|
vm86() respawning to fast when OVERLOAD_THRESHOULD is reached.
|
|
This way DOS has a better chance to catch up some additional
|
|
CPU time in order to be in schedule with pic_sys_time.
|
|
- Fixed dualmon messup (didn't work a lot of last releases).
|
|
|
|
So long,
|
|
Hans
|

<lermen@elserv.ffm.fgan.de>
|
|

|
|
working again.

- Dong's Mods for Pharlap extender capability which includes an
|
|
additional patch in ./dpmi/kernel.diff. This patch
|
|
(./dpmi/kernel.diff) will bomb on kernels > 1.2.7 as Linus has
|
|
included part of it (the last patch - to vm86.c) into 1.2.8.
|
|
Having said that, please choose to either :
|
|
1) Use emumodule which makes this all redundant
|
|
2) Use this full patch to kernels < 1.2.8
|
|
3) Remove the last part of this patch to vm86.c
|
|
if you are running a kernel > 1.2.7

|
|
DPMI support. There are 2 scripts load_module.sh and
|
|
unload_module.sh to make the module stuff easier for
|
|
newbies. You'll need to modify the
|
|
Makefile if you chose to go with emumodule support

|
specified for DPA are not already mounted. As it stands you get
|
|
an error if the fs is mounted read-write, and DPA read-only is
|
|
*not* specified. You get a warning if one is read-write and the
|
|
other read-only. Both read-only is accepted.

programs to DOSEMU to execute.
|
|
|
|
Basics:
|
|
|
|
Passing a command to DOSEMU:
|
|
============================
|
|
dos -E "command to be passed to DOSEMU" ....
|
|
....
|
|
C:\> unix.exe -e
|
|
>> RUNS command to be passed to DOSEMU <<
|
|
|
|
Executing the contents of an UNIX Environment Variable:
|
|
=======================================================
|
|
C:\> unix.exe -e ENV_VAR_NAME
|
|
>> RUNS COMMAND NAMED IN env_var_name <<
|
|
|
|
NB ENV_VAR_NAME will probably need to be in CAPITALS !
|
|
|
|
Running a UNIX Command:
|
|
=======================
|
|
(As Before...)
|
|
C:\ unix.exe ls -l /dev
|
|
>> RUNS "ls -l /dev" under Linux .... <<

|
- Patched in Scott's latest dosemu cleaning up.
|
|
Also from Scott:
|
|
James,
|
|
|
|
Well, I restarted the patch work that I sent to you some time ago. I
|
|
haven't gotten all the way through it yet (sadly), but here goes:
|
|
|
|
I propose a naming convention for the initialization procedures:
|
|
|
|
xxxx_init() for something that only gets called once
|
|
xxxx_setup() for something that gets called at each 'reboot'
|
|
(e.g. internal reboot -- the code that doesn't work)
|
|
|
|
- Dualmon patches from (mouw@morra.et.tudelft.nl> (Erik Mouw)
|
|
- Rewritten unix.c to compile under various DOS C-compilers.
|
|
|
|
Mon Jan 30 1995
|
|
|
|
- Must mention that JL has added an interrupt watchdog
|
|
timer so that the keyboard behind problem may be resolved.
|
|
- Backed out Marty's exchange_uids() as they were slightly
|
|
incomplete and causing video switching (etc) problems.
|
|
- #if 0'ed Marty's dbg_fd changes until this is complete.
|
|
This has caused some problems for folks trying to boot
|
|
DOSEMU.
|
|
- Added 2 sets of Lutz's DPMI patches.
|
|
- Added Ed's mouse garrot enhancements (inc mgarrot.com) to
|
|
reduce DOSEMU CPU time even more during mouse activity.
|
|
- Dissallowed video segment IPC attachment when Xdos is
|
|
used.
|
|
|
|
Fri Jan 27 1995
|
|
|
|
- Another week, and quite a few goodies. IPX updates
|
|
from Greg Page. Many mouse updates from Alan. Some
|
|
DPMI changes from Dong so that jed386 will run.
|
|
|
|
- Renamed termio.* to keyboard.c. Attempted to move all
|
|
keyboard functions into the keyboard subdir.
|
|
|
|
- Well, for better or worse, watch out world, I've started
|
|
back again on some of the client/server aspect. Remeber
|
|
that :-)? At this time, dosemu now creates a file:
|
|
/tmp/dosemu.<PID> with basic info and SHM id's. To
|
|
see how amazing this is (pun is intended!),
|
|
cd clients and make. Then you'll have 2 programs:
|
|
video - To just dump the dos processes 80x25 video screen
|
|
(Must NOT be in graphics or console mode)
|
|
keyboard - To dump what is in the DOSEMU keyboard buffer.
|
|
(NOT the DOS 40:?? buffer)
|
|
Both programs require a pid as parrameter 1.
|
|
|
|
Fri Jan 20 1995
|
|
|
|
- Additions by Denis Julitovto make ctrl-alt-del stuff work.
|
|
|
|
Fri Jan 16 1995
|
|
|
|
- Release pl40
|
|
- Upsetting the DPMI apple cart during testing of timer.exe. Now
|
|
the following rules have been applied with hacking :
|
|
1) calls to realmode procedures do NOT run handle_signals() so
|
|
that DPMI properly deals with them upon return.
|
|
2) hardware int's are first reflected to the possible
|
|
protected mode interrupt handle, which may (and usually
|
|
does) reflect them back to the realmode handler.
|
|
|
|
Fri Jan 13 1995
|
|
|
|
- Added Alan's mouse patches
|
|
- Added Scotts big patch to make int.c and move signals into signal.c
|
|
- Small patch to bios_emm.c so that seg -> phy requests are properly
|
|
handled.
|
|
Mon Jan 9 1995
|
|
|
|
- Small change to EMS so that Allocate pages allows allocation
|
|
of 0 pages. This allows Windows 3.0 to run small EMS frame.
|
|
- Scott has brought garrot into DOSEMU :).
|
|
- Got Hans's ./tools/sh.kversion to work. sorry Hans.
|
|
- beck@informatik.hu-berlin.de Michael Beck
|
|
Here it comes. The patch is very stupid, and add the classname XDosEmu
|
|
when dosemu runs with X-Support. Use fvwm's ICON "XDosEmu"
|
|
to get the icon.
|
|
BTW, perhaps someone should change the config-parsing, so instead of
|
|
the Iconname the user can set the classname.

I send you the package, but my english is very bad, so perhaps someone
|
|
check it and rewrote my readme (sorry for that, but my time is
|
|
limited now, the hollidays are over :-(
|
|
|
|
Sun Jan 8 1995
|
|
|
|
- Released pre0.53_39
|
|
- All Hans' patches to get a working kversion.h system in place.
|
|
Finally we can easily(?) keep dosemu working with various
|
|
releases.
|
|
- From Alan:
|
|
|
|
Hi James,
|
|
|
|
I saw in the code you've been doing a bit of hacking with 2/3 button
|
|
mice. Well I modified a bit of the code and hope this helps a little.
|
|
|
|
What I've done is provided switchable PC Mouse/Microsoft mice modes
|
|
within DOSEMU. I've re-written mouse.S to become mouse.asm (Sorry, I couldn't
|
|
suss out gas to compile dos progs, so I had to use a86). Anyway I've also
|
|
provided the NEW ! raw mouse.com at the end of this message in uuencoded
|
|
format.
|
|
|
|
There have been a few more subtle changes to the code that you'll
|
|
probably notice too. One of the more obvious, is that the internaldriver
|
|
now can have 3 button emulation on 2 button mice.
|
|
|
|
Anyway MOUSE.COM now takes some arguments...
|
|
|
|
r - resets the iret. Put "mouse r" in your autoexec now..
|
|
i - inquire current configuration of mouse driver.
|
|
p - Set PC Mouse mode (3 buttons)
|
|
m - Set Microsoft mode (2 buttons)
|
|
|
|
I'll be implementing more as we go along...
|
|
|
|
Some of the PS/2 Mouse BIOS routines have been deleted/re-written, as the
|
|
existing code was wrong.
|
|
|
|
Alan.
|
|
|
|
Hi again.
|
|
|
|
Some more fixes.
|
|
|
|
Apparently according to my documentation there are some wrong doings
|
|
in the show/hide stuff. There should be a counter which if 0 the cursor shows,
|
|
but it is possible to do ... hide(), hide() which will make the counter -2,
|
|
then doing a show() with put the counter at -1, but will still not show the
|
|
cursor. Doing another show() will make the cursor appear.
|
|
|
|
- Alan's patches to get Hans' emumod system compiling again.
|
|
- Added new lredir.exe and lredir.c from Tim Josling <tej@melbpc.org.au>:
|
|
|
|
The problems fixed are:
|
|
|
|
Doesn't check that argv[2] exists before using it, causing a loop in some
|
|
cases.
|
|
|
|
Function that returns nothing is specified to return some type of int,
|
|
causing compiler complaints.
|
|
|
|
Drive mounted read-only is reported as read-write.
|
|
|
|
I tested the fixes pretty thoroughly so they shoudl be OK. I compiled
|
|
with Turbo C++ 3.0 when I tested them.
|
|
|
|
The file below is the full source in dos format (with ^M's). I tried to
|
|
generate a diff file but this didn't work as the original file didn't
|
|
have the ^M's on many lines so as my editer put them on every line I
|
|
ended up with many spurious diff's.
|
|
|
|
The version of lredir was the one from 0.53pl37.
|
|
|
|
Regards,
|
|
Tim Josling
|
|
|
|
- Added Lutz's latest DPMI patches. GO32 now runs and shows
|
|
memory. Some go32 DPMI programs are running. Yah Lutz.
|
|
|
|
Wed Jan 4 1995
|
|
|
|
- Released pre0.53_38. Happy New Year.
|
|
- Added Marty's next set of patches.
|
|
- Moved Hans' enhancements form 'make doeverything' to
|
|
'make itall' so that as kernels change, make doeverything
|
|
remains OK.
|
|
- Jiggled around where ioctl's to acquire_vt were in vc.c in
|
|
an effort to stop more of the VC switch hanging bug.
|
|
|
|
Tue Jan 3 1995
|
|
|
|
- Added Marty's Unix.exe to send unix commands from DOSEMU.
|
|
To use, just ln files to a unix.exe that you wish to run.
|
|
I.E:
|
|
ln ./commands/unix.exe ls.exe
|
|
from within dosemu, just enter ls and the ls command is executed.
|
|
- Added two parms to call to show_reg( __FILE__, __LINE__) to
|
|
track down where show_regs() are being called from.
|
|
|
|
Sun Jan 1 1995
|
|
|
|
- Added return to getKey() function in ./keyboard/termio.c when
|
|
screen is not current. Fixed screen lockups here.
|
|
- Removed (added #if 0) code setting bs_pos to -1 for root dir deletes
|
|
|
|
Mon Dec 19 1994
|
|
|
|
- Added Marty's latest Makefile enhancements. This included 2 new
|
|
files (data.c extern.h) and including int.h inside of
|
|
emu.c. Marty promises emu.c will get smaller :-)
|
|
- Added Lutz's latest DPMI enhancements.
|
|
|
|
Sun Dec 11 1994
|
|
|
|
- Changed check for mouse in graphics mode by using video
|
|
regs.
|
|
- Latest updates from BOCHS project.
|
|
- Modified MICKEY concept in mouse.c so that WordPerfect now
|
|
works with internal mouse. Doing this blind folks. Anxiously
|
|
waiting for Alan's next set of mouse enhancements.

|
|
|
|
Fri Dec 9 1994
|
|
|
|
- Release pl37
|
|
- Added garrot02 to dosemu. I think it should be separate on
|
|
tsx?
|
|
|
|
Sat Dec 3 1994
|
|
|
|
- Update to add different X fonts :
|
|
|
|
Hi!
|
|
|
|
I just added support to change the font used with XDOS. There is a new
|
|
keyword, "font", in the X-section of the config file which allows you to
|
|
specify the font to be used. If the font is not a monospaced font (or can't
|
|
be found) "vga" is still the default.
|
|
|
|
There is no translation done, i.e. the font has to be an IBM font!
|
|
|
|
So, if someone wants to create a smaller font...
|
|
|
|
BTW, the include file "linux/segment.h" changed to "asm/segment.h" somewhere
|
|
around linux 1.1.67 (it is used in dpmi.c).
|
|
|
|
The diffs are against pre0.53pl36.

|
|
|
|
- Release pl36.
|
|
|
|
Mon Nov 28 1994
|
|
|
|
- Added -D__ASSEMBLY__ to get emumodule.o going again in
|
|
later kernels :-).
|
|
- Some problem in RPT_SYSCALL, so went back to SA_RESTART and
|
|
set RPT_SYSCALL to return.
|
|
- Added mouse.com which causes int33 to be redirected away from
|
|
an iret. Now Foxpro mouse works in X, but still no WPO :(.
|
|
|
|
Sun Nov 27 1994
|
|
|
|
- Major -(Thats MAJOR)- restructure of the directories and
|
|
dosemu files. Marty is a busy man.
|
|
- Got Han's latest bios.S working with Hans help :).
|
|
- EMS patches from JL.
|
|
- Made Novell access single mode again for default.
|
|
- Verified alt keys are working well, as well as alternate
|
|
slang keys.
|
|
- Latest memory access for cross-platform development thanks
|
|
to Kevin for the Bochs team.
|
|
|
|
Tue Nov 21 1994
|
|
|
|
- Added RPT_SYSCALL's to some writes. Kinda kludgy for know :-(
|
|
- Latest SLANG enhancements:
|
|
Hi,
|
|
|
|
I added the ability to access ALT, SHIFT, and CONTROL keys for remote
|
|
terminals. For example, one can now use alt function keys as well as
|
|
Ctrl-Backspace, Shift-tab to get the backtab, Ctrl-Arrow, etc....
|
|
|
|
Below, you will find a uuencoded file called `files.tar.gz'. After
|
|
unpacking it, you will see: termio.c, slang-termio.c, and terminal.c.slang.
|
|
The latter files should go in the `video' subdir and the other two go in the
|
|
`keyboard' subdir. `termio.c' is exactly like the one already there. The
|
|
changes are marked by `#ifdef USE_SLANG' stuff.
|
|
|
|
Note that in slang-termio.c, you will find 3 global variables:
|
|
|
|
static char *Alt_Shiftkey = "^@A";
|
|
static char *Ctrl_Shiftkey = "^@C";
|
|
static char *Shift_Shiftkey = "^@S";
|
|
|
|
These should be initialized by the user by whatever mechanism you prefer.
|
|
They represent the keysequence that invokes the appropriate modifier key,
|
|
e.g., to get the next key ALT, press `Ctrl-@ A'. Perhaps, it might be
|
|
easier to simply use `Ctrl-A' but I wanted to demonstrate that one can use a
|
|
multiple character key sequence. When one of these keys are pressed, an
|
|
indicator will appear at the bottom of the screen indicating this. (The new
|
|
terminal.c.slang does this).
|
|
|
|
I had a terrible time getting the ESC key timout to work properly at 2400
|
|
baud. As a result, I have eliminated the ESC timeout from the slang
|
|
version. If you want to send an ESC, hit it twice. The alternative simply
|
|
does not work and hitting it twice when an escape is needed is alot less
|
|
painful. One can always rebind the escape key on the terminal emulator to
|
|
send two escapes.
|
|
|
|
Obviously, we will want to add some mechanism to rebind keys. I do not
|
|
believe that relying on the keys as defined in termcap is adequate. For
|
|
example, one might want to rebind Ctrl-E to escape for a DOS program that
|
|
uses the ESC alot.

- Rod May has noted that due to race conditions in the kernel
|
|
during partition access in kernels in the 1.1.51 - 1.1.61 and
|
|
I believe 1.1.63. Don't have his E-mail here, but it DOES
|
|
CAUSE CORRUPTION and therefore BEWARE of using PARTITION
|
|
ACCESS in these kernels!
|
|
- First steps towards making DOSEMU platform independant by

Makefile.common system.
|
|
|
|
Sat Nov 12 1994
|
|
|
|
- Release pre0.53_33.
|
|
- Han's latest, now he has a self-contained emumodule that includes
|
|
SIG and really gives DOSEMU the power it has desired for quite some
|
|
time to make use of the kernel. You will need to set the #if 0 to 1
|
|
in emu.h as well as:
|
|
/* From Hans: If you you need the emumodules special features
|
|
* You also must load the modules as follows:
|
|
* login in as root
|
|
* cd /usr/src/dosemuXXX/syscallmgr
|
|
* ./insmod syscallmgr.o
|
|
* ./insmod -m ../emumod/emumodule.o
|
|
*/
|
|
|
|
More background:
|
|
|
|
Hi Jim
|
|
|
|
As you didn't show up at IRC, I send you some explanations about the
|
|
new emumodule stuff and inbedded sillyint.
|
|
|
|
I established two interfaces to the emumodule, which I think can be
|
|
expanded for all other features, that we need in the future:
|
|
|
|
1. A standard Linux systemcall (over syscallmgr) for all
|
|
functions that needs the kernel support functions (like printk).
|
|
During within this syscall, the scheduler and/or an interrupt
|
|
may take away control from dosemu.
|
|
The calling convention of this syscal is defined in
|
|
./include/emusys.h as
|
|
extern inline int emusyscall(int mode, int params)
|
|
and can be called at this time as
|
|
|
|
result = emusyscall(EMUSYS_GETVERSION,0);
|
|
result = emusyscall(EMUSYS_GETSUPPORT,0);
|
|
result = emusyscall(EMUSYS_REQUEST_IRQ,irqnum);
|
|
result = emusyscall(EMUSYS_FREE_IRQ,irqnum);
|
|
|
|
2. I implemented a so called fast syscall via an INT 0xe6 to Linux
|
|
(not to DOS).
|
|
This syscall has not the great overhead that the standard syscall
|
|
has and can't be interrupted by Linux's scheduler or interrupts.
|
|
With this we can access kernel space much faster then with kmem
|
|
or other techniques and also we can set some bits of emumodules
|
|
variable. We can check some status, and after return from
|
|
fastsyscall we are shure that the status is what it says.
|
|
Its also possible to realized some of the DPMI functions with
|
|
this kind of syscall.
|
|
But, this syscall must run with interrupts disabled, and also
|
|
can only use some the kernels macros, but not the support functions
|
|
which leads to rescheduling e.t.c.
|
|
I used this type of syscall to get and reset the IRQ-bits of
|
|
sillyint.
|
|
Also the fastsys calls are defined in ./include/emusys.h and
|
|
currently there exists:
|
|
|
|
extern inline int fastsyscall(int mode) /* generic call */
|
|
extern inline int get_and_reset_irq(int irqnum)
|
|
extern inline int get_and_set_irq(int irqnum)
|
|
extern inline int get_irq_bits(void)
|
|
|
|
To enable dosemu to use the new features there must be REQUIRES_EMUMODULE
|
|
defined in emu.h (see at the comments at top of this file).
|
|
If it is not defined, sillyint is used as usual.
|
|
|
|
One thing at last: I always are on war with "make", so please check
|
|
and change the Makefiles, that they do compile emumod/ and syscallmkgr/
|
|
if REQUIRES_EMUMODULE is set. I was to silly to do so.
|
|
I also would like to do make from the subdirectories directly during
|
|
devellopment phase.
|
|
|
|
...Ah, and the patch fits into 0.53.32 with dualmon.patch already in.
|
|
|
|
So long
|

<lermen@elserv.ffm.fgan.de>
|
|
|
|
- Small patch to ./mouse/mouse.c which resets the initiated mouse
|
|
subroutine on calls to fnx 0x21. This previously wasn't reset and
|
|
caused future programs to crash DOSEMU when they loaded over that
|
|
space. Now to see why some programs (Foxpro/Word Perfect Office)
|
|
don't recognize the internal mouse driver :-(.
|
|
|
|
Wed Nov 9 1994
|
|
|
|
- Various patches from lee@tengu.in-berlin.de (Kang-Jin Lee) to
|
|
makefiles.
|
|
|
|
- From Hans :
|
|
# - If you have a dual-monitor configuration (e.g. MDA as second display),

Hi James!
|
|
yep, this is an interesting point. It's not just lilo that will
|
|
have problems, some other boot sector programs (which rewrite the MBR)
|
|
will need this "workaround" and therefore won't work with this patch.
|
|
(I would recommend using one of the newer boot sector programs as they
|
|
are better than lilo, but this is a different point).
|
|
Unfortunately this "workaround" is a very poor long term
|
|
solution, as using the current part-table is the only safe option.
|
|
This only affects people who boot using DPA with lilo up their MBR, but...
|
|
Since we are basically hacking the part-table to only one valid bootable
|
|
partition, a solution is to cut out the middle-man and boot the partition
|
|
directly, this way we get the current part-table and whatever boot
|
|
sector code you have is irrelevant. Patch to emu.c follows....
|

From: Rod May <stoke@melbourne.DIALix.oz.au>

Hi there,
|
|
here's a patch (to pl28) which makes the use of "mkpartition"
|
|
unnecessary for direct partition access. Also the partition number is no
|
|
longer required. i.e. instead of specifying:
|
|
disk { partition "/dev/hda3" 3 } and running "mkpartition",
|
|
you only have to specify:
|
|
disk { partition "/dev/hda3" }
|
|
The MBR is read from the appropriate hard drive during start-up.
|
|
Not only does this simplyfy things but stops potential mistakes
|
|
including: out of date MBRs, specifying hda instead of hda3 etc.
|
|
These were not flagged before and could lead to "interesting" results.
|
|
Using the old format will get you a config warning but otherwise
|
|
the partition number will just be ignored,
|
|
Ciao,
|
|

Hi Jes -
|
|
|
|
Here is the new pic code. It is implemented as contidional code, so you'll
|
|
have to un-comment a line in the Makefile if you want to try it.
|
|
Look for the string NEW_PIC in the Makefile; the instructions are right
|
|
before it.
|
|
|
|
Because the serial.c pic mods don't work very well yet, I have provided
|
|
two options: The firstone only implements pic for keyboard and timer code.
|
|
This stuff is pretty solid, and I would appreciate bug reports, etc.
|
|
The second option implements pic for timer, keyboard, and serial interrupts.
|
|
The serial code is knows to have bugs, although it is useable. PLEASE,
|
|
if all you know is that the serial code doesn't work right, DON'T send
|
|
a bug report. I already know that much :-). On the other hand, if you have
|
|
a fix, or even just a partial one, please let me know. The serial bug
|
|
shows as an extermely low send rate; only half as fast as whennot using pic.
|
|
|
|
I would appreciate any bug reports on the keyboard and timer code. They are
|
|
not complete, but I believe this code to be bug-free.
|
|
|
|
And now, a (very) little technical information for the curious:
|
|
|
|
There are two big differences when using pic. First, interrupts are not
|
|
queued beyond a depth of 1 for each interrupt. It is up to the interrupt
|
|
code to detect that further interrupts are required and reschedule itself.
|
|
Second, interrupt handlers are designated at dosemu initialization time.
|
|
Triggering them involves merely specifying the appropriate irq.
|
|
|
|
Since timer interrupts are always spaced apart, the lack of queueing has no
|
|
effect on them. The keyboard interrupts are re-scheduled if there is
|
|
anything in the scan_queue. The keyboard pseudo-input register,
|
|
*LASTSCAN_ADD, is set to 1 (an otherwise unused value) to indicate that it
|
|
has been read, and can therefore be re-filled. Both the keyboard and timer
|
|
bios routines now have outb 0x20 to signal the EOI. The OUTB_ADDR is no
|
|
longer used.
|
|
|
|
This has been slow in coming, I know; and it will be a while before it gets
|
|
fully utilized. But, at least when the serial code gets done, it should
|
|
help get dpmi on its way. I'll keep working on this; I think it has a lot
|
|
of potential to help organize the code. Good luck with it to all, and
|
|
thanks in advance for any comments.

Hi there!
|
|
Here's my patch for allowing DPA access to specific logical
|
|
partitions under dosemu. It applies to the patch level 27 code of
|
|
disks.[ch].
|
|
Access to specfic logical partitions, rather than entire
|
|
extended partitions, is a great idea for the same reason that partition
|
|
access is better than wholedisk access: one day a poor linux
|
|
partition will suffer. Its used by specifying a part number greater
|
|
than 4 e.g.:
|
|
disk { partition "/dev/hda5" 5 }
|
|
the number itself does mot matter (as long as its greater than 4) as it
|
|
is the device name that's used to derive the part table entry info.
|
|
The only query is that I raised the MAX_HDISKS in disk.h from 4 to 8,
|
|
(I'm using 7 at the moment with no probems). Also I wasn't sure of the
|
|
number to pass to leavedos for the BLKGETSIZE error, is there a
|
|
convention for this?
|
|
This should never never happen though (famous last words).
|
|
Hope this is useful to others,
|
|
email me with any questions,
|
|
|
|
Ciao,
|
|
Rod May.

Sun Oct 02 1994 Jmaclean
|
|
|
|

|
- Added 10 bytes to the malloc for 1 dir_ent struct, as the
|
|
dir_emt size seems too small. This fixes some bad mfs.c bugs.

|
|
memory. Fastest fix for a bug I've seen :-).
|
|
- Modified CHECK_HANDLE to deal with non-active handles as it
|
|
was previously just checking for ranges. This fixes Hans
|
|
finding of mem/d giving extraneous info.
|
|
- Moved Lutz's DPMI signal calls to within the signals for Hans.
|
|
|

Wed Sep 28 1994 Jmaclean
|
|
|
|
- Fixed one definite place for Divide/Stack Overflow to occur in int.h.
|
|
Problem occured when a default interrupt was called by a redirected
|
|
interrupt. This caused a recursion to the never lands.
|
|
|
|
Tue Sep 27 1994 Jmaclean
|
|
|
|
- Released pre53_23.tgz in diff form only.
|
|
- Added Jan's latest Configure script with X support. Modified
|
|
it to cp with backups /etc/dosemu.conf to /etc/dosemu.conf.backup.
|
|
- Remade first part of convascii of termio.c where esc seq's
|
|
are translated. Involved working around select getting
|
|
interrupted.
|
|
- Fixs to serial woes added in termio.c - keyboard_init().
|
|
Moral of this story? A baud rate of 0 (B0) is equivalent to
|
|
sending the process -SIGHUP. Real fix added to ./video/terminal.c
|
|
by moving raw() statement to AFTER initscr() as spec'd in ncurses.
|
|
- Fixed to memory access errors in vga.c. Funny they seem to have
|
|
been OK when handled in a signal?. Now folks should be able to
|
|
resume switching VC's :-).
|
|

return code for testing if DOSEMU is running.
|
|
- Added MDA as valid card selection in dosemu.conf (=MGA)
|
|
- Some goodies from Hans Lerman:
|
|
|
|
Well, here now is the summery of things that are in my patches which
|
|
I have tested under Linux-1.1.50.
|
|
( the patches come in a separate mail, because my mailer cannot handle
|
|
too large mails )
|
|
|
|
1. Loadable driver sillyint.o
|
|
It is compiled via a normal "make doeverything"
|
|
and put into the directory /boot/modules.
|
|
I changed the sig/Makefile, it also needs to know where the kernel
|
|
sources are (USRSRCDIR).
|
|
The source needs a -DMAKE_LOADABLE_DRIVER to compile sillyint.o
|
|
The same source can be used (without the -DMAKE..) to compile the
|
|
kernel linked in driver. I changed the sig/HowTo.
|
|
|
|
The device major is put into an global variable SIG_MAJOR, so it
|
|
can be changed on loadtime by
|
|
insmod /boot/modules SIG_MAJOR=31
|
|
|
|
|
|
2. Multiple SIG IRQ's can be defined in /etc/dosemu.conf and
|
|
also wether to use SIGIO or not. (see examples/config.dist)
|
|
Because of "sillint off", there is no need to disable SIG
|
|
via compile time option SIG. I recommend to let it be #define SIG 1.
|
|
I did not succeed with setting up a test for two IRQs at the same time,
|
|
so me and other people have to test it in the future.
|
|
|
|
|
|
3. Mapping of hardware ram is configurable via
|
|
|
|
hardware_ram { 0xc8000 } # one 4K page mapped
|
|
or
|
|
hardware_ram { 0xc8000 range 0xcc000 0xcffff } # multiple mapped pages
|
|
|
|
I added an overlap test to avoid wrong mapping, it is done after
|
|
configuration is finished, so it should catch all errors.
|
|
It relates to EMS, VBIOS and HARDWARE_RAM.
|
|
|
|
|
|
4. EMS-frame is now movable (needed for ram conflicts).
|
|
The ems keyword is expanded as follows:
|
|
ems { 1024 ems_frame 0xe000}
|
|
or
|
|
ems { ems_size 1024 } # defaults to old size of 0x10000
|
|
|
|
But the old syntax is valid too.
|
|
|
|
|
|
5. Size of VBIOS now configurable (most BIOSes at 0xc0000 have only 32K
|
|
so I can gain some space for hardware ram and/or UMBs).
|
|
/etc/dosemu.conf line:
|
|
added flag "vbios_size"
|
|
|
|
|
|
6. I corrected a situation (not a bug) concerning the "c" debug flag.
|
|
If "c" was switched off in /etc/dosemu.conf, you could not get
|
|
the config printout via
|
|
dos -D+c
|
|
Now this is possible.
|
|
|
|
|
|
|
|
That's all for now, ...so long,
|
|

Sat Sep 24 1994 Jmaclean
|
|
|
|
- Messed more with timer interrupt so that setting date backwards
|
|
doesn't cause divide overflow. Seems to fix it for going
|
|
ahead and back through time. Only problem is that when DOS
|
|
sees it's past 24hrs, it always moves its date ahead a day :-(.
|
|
- Changed config.graphics to config.vga in emu.c to control
|
|
setting allowvideoportaccess to 0.
|
|
- Added vc switching (set_process_control) to new signal_queue.
|
|
From conversation with JL I'm not sure this is gonna be solid
|
|
since now the signal_queue being run to switch VC's will rely
|
|
on returns from vm86().
|
|
Still doesn't fix bad crashing when running Windows3.0 which
|
|
takes down my whole UNIX box :-(.
|
|
- Stopped DOSEMU from exiting when no diskette in drive.
|
|
- Added note to add users to /etc/dosemu.users in QuickStart.
|
|
- Fixed parsing of -C option to NOT expect arguements.
|
|
|
|
Thr Sep 22 1994 Jmaclean
|
|
|
|
- PRE53_21 Released.
|
|
- Messed with timer code. Changed tick setting to different
|
|
method and relied on time() to give acurate time.
|
|
Found what seems to be the 24 hour bug and inilated it!!!!!!
|
|
With many thanks to Corey.
|
|
- Added backspace/delete patch to Xkeyb.c. Thanks to Scott and Mark.
|
|
- Hacked up HogThreshold again. Rule: Closer you set to 0, the
|
|
lower the CPU usage. At 0 though, hogThreshold is turned off,
|
|
and int16/int2a are run full open.
|
|
- Added HogThreshold to int2a.
|
|
- Added patches to bring -F config file option back to life
|
|
thanks to Dino Dini <ddini@dircon.co.uk>.
|
|
- Added patches to ./video/X.c for better color reps thanks
|
|
to Mark.
|
|
- Prepared to move vc_acquire/release under new signal
|
|
handling... but failed miserably :-(.
|
|
- Makefile additions by Mark.
|
|
|
|
Tue Sep 20 1994 Jmaclean
|
|
|
|
- Removed most coding from SIGIO and SIGALRM signals in an
|
|
effort to remove race conditions. Now these signals just
|
|
mark that they've occured, save their context, and
|
|
continue. Lutz's DPMI will suffer :-(. Probably best to
|
|
go through DANG to get an idea of what's going on :-).
|
|
|
|
Mon Sep 19 1994 Jmaclean
|
|
|
|
- Wrapped lpt opens in exchange_uids() to allow "lpr" to run at
|
|
user level.
|
|
- Modified Makefile to create libdosemu$(EMUVER)pl$(PATCHL) and link
|
|
libdosemu to it. Now folks can compare releases just by changing
|
|
symlinks. Probably not what was wanted, but a close facsimile :-).
|
|
- Added SIG mods by Hans Lermen (lermen@elserv.ffm.fgan.de). More to
|
|
come.
|
|
- Cleaned up boot() in emu.c to just boot. Added memory_init() for
|
|
all specific memory setups for proper i86 boots.
|
|
- Added portuguese keyboard map.
|
|
|
|
Sun Sep 18 1994 Jmaclean
|
|
|
|

|
|
- Started DANGing :-).
|
|

|
Thanks to Alan for providing a fix... But I did it ...
|
|
my way :-). Hope you don't mind Alan.
|
|
|
|
- Fixed SERIAL not working. Martin's code was returning in
|
|
outb before anything was done :-(.
|
|
|
|
- And now a little from Alan...:
|
|
|
|
Hi James..
|
|
|
|
Not my usual stuff but I had to fix it.
|
|
|
|
The parser seemed to be screwed up for me, in that it parsed two
|
|
files, both the local .dosrc and the /etc/dosemu.conf, this resulted in
|
|
the first linux drive becoming f:. All because the system though I had two
|
|
hard disks and one floppy image due to the parsing twice of the configs.
|
|
|
|
Anyway attached is a fix so that it parses the local .dosrc first...
|
|
If it doesn't find one it takes the /etc/dosemu.conf.
|
|
|
|
Secondly, I've implemented an /etc/dosemu.users file, similar to
|
|
minicom's way of working. This allows only selected users to execute dosemu.
|
|
Create the /etc/dosemu.users file with, on each line, the name of the user
|
|
allowed to execute DOSEMU.
|
|
This approach could be later expanded to specifying devices in the
|
|
dosemu.users file, so that only selected users are able to open specific
|
|
devices.
|
|
Thirdly, I had to fix up the Makefile a little for ease of use.
|
|
Notice I've defined an X11LIBDIR now too.
|
|
|
|
Cheers.
|
|
|
|
Alan.
|
|
|
|
- Also:
|
|
|
|
James,
|
|
For some reason the gfx_cursor for the mouse was commented out.
|
|
I checked the docs and someone commented it out because it was crashing the X
|
|
stuff. Well, This fix should get rid of that. As it only call mouse_do_cur()
|
|
if we are not running X. Before it was trying to mmap even when X was running.
|
|
Bad idea .....
|
|

|
Tue Sep 06 1994 Jmaclean
|
|
|
|
- Added sig subdir with Silly Interrupt Generator in toe. Did
|
|
some preliminary testing with SIG to get it working with
|
|
1.1.x kernels.
|
|
|
|
Mon Sep 05 1994 Jmaclean
|
|
|
|
- From Rain:
|
|
|
|
I guess I let this stuff rust on my harddisk long enough, so here's
|
|
another patch ;)
|
|
|
|
It includes:
|
|
|
|
- support for 28/43/50 line modes
|
|
- make xdos exit properly when it fails to open the X server
|
|
(!includes a change to the printer code!)
|
|
- a color (xpm) icon :-)
|
|
- auto-detection of readonly floppies, which newer kernels require.
|
|
|
|
It also includes my attempts to make bios scrolls scroll the X window
|
|
directly, in the hope that it would make things faster.
|
|
However, I found that it's at least as often slower as it's faster...
|
|
|
|
I disabled the code and left it in just because Mark might be interested
|
|
to use it for the terminal modes.
|
|
|
|
bye,
|
|
Rainer
|

|

- From Martin Ludwig :
|
|
|
|
Hello James!
|
|
|
|
Here is my diff of dosemu pre53_12 to use a second (HGA) monitor for
|
|
dosemu while using X. I hope it will patch against pre53_15, too.
|
|
|
|
Changes against pre53_12:
|
|
* new switches -Y and -Z: giving the names of the keyboard and mouse pipe
|
|
* keyboard input from pipe instead of STDIN
|
|
* mouse input from pipe instead of asking a mouse port
|
|
* doesn't install video-bios, uses int10.h instead
|
|
* watches port I/O of HGA-card and remapps video-memory if the second
|
|
page is used
|
|
* uses an own cursor position routine (the one in dosemu 0.52 was removed...)
|
|
* new X-prog (xdos) which sends mouse and keyboard events from X
|
|
to dosemu, emulating a raw keyboard
|
|
|
|
Bugs:
|
|
* no semaphore for the HGA-memory
|
|
* no mouse in graphics mode
|
|
* no test if HGA-card is there
|
|
* it leaves rxvt or xterm disturbed if started from there
|
|
* problems with msherc-programs and the second page
|
|
* large xdos-window
|
|
* some others, I think
|
|
|
|
Future plans:
|
|
* remove the bugs
|
|
* data exchange with X-progs
|
|
* perhaps an CGA or EGA emulator for HGA
|
|
|
|
|
|
Copyright:
|
|
* the same conditions as for dosemu
|
|
|
|
I hope that's all, here is the diff

|
|
|
Tue Aug 30 1994 Jmaclean
|
|
|
|
- Added dosconfig script by Jan Vandenberghe. Requires DIALOG. I like
|
|
it :-).
|
|
- Included patches from Heiko for X and timer.
|
|
- Fixed emubat config thanks to Scottb.
|
|
- Modified io_select() calls to start dividing into 2 camps,
|
|
those that use sigio and those that don't.
|
|
- Added SIGIO ability to internal mouse driver.
|
|
|
|
Fri Aug 26 1994 Jmaclean
|
|
|
|
- Fix that HJ already sent in and I missed :-( for the
|
|
-T arguement of ld from flebbe@tat.physik.uni-tuebingen.de.
|
|
|
|
Wed Aug 24 1994 Jmaclean
|
|
|
|
- Added Enhancements to CDROM driver by Karsten Rucker.
|
|
- Added Lutz's STI patches and kernel patch sti.pat in .kernel
|
|
|
|
Fri Aug 19 1994 Jmaclean
|
|
|
|
- Changed OpenKeyboard to keyboard_init and closeKeyboard
|
|
to keyboard_close. Moved these out of video init procs and
|
|
into there own separate calls. This was causing problems
|
|
in video_config_init() as it would map in video bios
|
|
illegally :-(.
|
|
- Added Conditional for SIG in sigalrm to help io_select()
|
|
|
|
Wed Aug 17 1994 Jmaclean
|
|
|
|
- Added scan to charcode returned in Xkeyb.c by put_key()
|
|
- Tried to get lexer.l back up :-(
|
|
|
|
Tue Aug 16 1994 Jmaclean
|
|
|
|
- Messed around with Rain's patches until all modes started
|
|
to work. Mostly order of routines during initialization
|
|
that had minor problems. Now for example, telnet works
|
|
again.
|
|
|
|
Sun Aug 14 1994 Jmaclean
|
|
|
|
- Removed SOME __inline__'s from mfs.c, still memory pig :-(.
|
|
- Rain's latest patches.
|
|
- Minor fixups to various files.
|
|
- New Makefile from Mark.
|
|
|
|
Sat Aug 12 1994 Jmaclean
|
|
|
|
- Added Rain's massive cleanups and X mouse support. This is
|
|
NOT tested and will need some time to smoothen out.
|
|
- Added keymaps fixes for sg-latin1 from :
|
|
pingu@satu.baboon.ch (Ruedi Kneubuehler).
|
|
|
|
Fri Aug 12 1994 Jmaclean
|
|
|
|
- Added Scottb's patches to bios_emm.c and lexer.l
|
|
- Added lsm to ./doc subdir
|
|
|
|
Thr Aug 11 1994 Jmaclean
|
|
|
|
- Fixed keyboard latin1 statement and latin1 codes for better
|
|
emualtion thanks to vilva@xiron.pc.helsinki.fi (Veijo Vilva).
|
|
|
|
Wed Aug 10 1994 Jmaclean
|
|
|
|
- Added back some termio ioctl's to set ISTRIP,IGNBRK,OPOST
|
|
and such. Seems to remove backspace in non-rawkeyboard
|
|
mode.
|
|
- Added -lfl to toplevel makefile for fixing new parser not
|
|
resolving required libs.
|
|
- Added check to NOT add release key for ascii's with high
|
|
byte 0x00.
|
|
|
|
Mon Aug 08 1994 Jmaclean
|
|
|
|
- Thanks to Rob for pointing out the NCURSES raw() command
|
|
interference by way of his messages, the ICRNL thing should
|
|
be dispersed, and replaced with possible new bugs :-).
|
|
- CD-ROM extensions for DOSEMU with thanks to Karsten
|
|
Rucker (rucker@astro.uni-bonn.de).
|
|
- Parser additions from Scottb. We are back to the NEW
|
|
parser. Developer/Tester beware :-).
|
|
- DOSEMU-HOWTO updates from Mike.
|
|
|
|
Fri Aug 05 1994 Jmaclean
|
|
|
|
- Added kludge to keyboard so that keypresses in non-console
|
|
keyboard mode send keypress then keyrelease sequences. This
|
|
seems to fix atleast WordPerfect double chars. Doesn't
|
|
seem to help German aumlets though :-(.
|
|
- Scottb's latest parser patches adding back emu(sys/bat) and
|
|
a debug { X on } option.
|
|
|
|
Thu Aug 04 1994 Lutz
|
|
|
|
- dpmi/call.S is now totally rewritten to fix a problem with
|
|
returning to DOS code (stack problem).
|
|
- CallToInit() deleted
|
|
- more dpmi cleaning/preparing
|
|
|
|
Wed Aug 03 1994 Jmaclean
|
|
|
|
- Added patches from Tomi, Scottb to new parse generator...
|
|
but put back in old parse generator fot this release. Well
|
|
step back to this one hopefully in the next release.
|
|
- Added Rain's Xdos patches. Folks, we're well on our way :-).
|
|
Please read README.X and thank Rain for getting everything on
|
|
it's way.
|
|
|
|
Mon Aug 01 1994 Jmaclean
|
|
|
|
- Added new parser combo lexer.l/parser.y from Scott for all
|
|
to play with. A bit rough but Scott would enjoy feedback :-).
|
|
- Fix for bug in cursor positioning that causes garbage sometimes
|
|
This can be a MAJOR improvement to some people because it's appliation-
|
|
specific.
|
|
- Invisible cursor support in console mode. More visually pleasing.
|
|
- Cursor in ANSI and NCURSES is now put at position 0,0 whenever the
|
|
cursor is invisible or off-screen.
|
|
- Improvements to character blinking disable/enable code (this stops the
|
|
annoying blinking when you run PCTools over a telnet line)
|
|
|
|
- Note from Markkk about new ansi_xterm :
|
|
|
|
"ANSI Xterm 2.0 is a specially modified Xterm that is compatible with DOSEMU
|
|
and to enable the use of all 16 colors, and the entire PC character set.
|
|
This makes DOSEMU just like xdos in this area!
|
|
|
|
Furthermore, just follow the instructions included with ANSI Xterm 2.0
|
|
for an easy compile. Then all you need to do is type "xdosemu" to bring
|
|
up an Xwindow running DOSEMU. The xdosemu command automatically detects
|
|
for the existence of ansi_xterm. If it does not exist, it detects for
|
|
a regular xterm and rxvt next.
|
|
|
|
Try it, and let Mark Rejhon know at mdrejhon@csclub.uwaterloo.ca
|
|
as he is responsible for this."
|
|
|
|
Mon Aug 01 1994 Jmaclean
|
|
|
|
- Markks latest and greatest additions to the Xterm capabilities
|
|
of DOSEMU. Best to get ansi_xterm from a site at this time :-).
|
|
- Detach capability added, thanks to Karl Hakimian. Now with
|
|
the optional -d parm, a new VT will be switched to for starting
|
|
and running DOSEMU.
|
|
- Added __map_page() to fix EMS error caused by remap() calling
|
|
__unamp_page() first. FoxPro is running again.
|
|
|
|
Fri Jul 29 1994 Jmaclean
|
|
|
|
- By Jon's request, set '_''s to '-' in keyboard parms
|
|
in examples/config.dist
|
|
- By Jon's request, added 'make most' option which does
|
|
NOT make the doc subdir.
|
|
|
|
Tue Jul 26 1994 Jmaclean
|
|
|
|
- Thanks to Scottb which fixed the DOSEMU memory problems
|
|
with pointing out that mmap annonymous needed PRIVATE and
|
|
not SHARED to work :-) We're back on the road again .
|
|
|
|
Sat Jul 23 1994 Rain
|
|
|
|
* Largely reworked {re}{un}map_page, removed v_mmap.
|
|
COPY/MMAP/IPC_EMS conditionals are now in map_page and friends.
|
|
Fixed MMAP_EMS: mmap() mapped the wrong way around (-:
|
|
Still doesn't work, mmap() patch is broken :-(
|
|
* EMS_IPC is completely screwed up and probably not easy to make work.
|
|
The problem is that one cannot do partial mappings of shared
|
|
memory regions. Left it in, though.
|
|
* added COPY_EMS conditional (for the standard 'mapping' method)
|
|
* added UNMAP_BEFORE_MAP conditional to leave out unmapping
|
|
of old mappings in map_page for MMAP_EMS.
|
|
Shouldn't be necessary because the kernel'll do this for us.
|
|
* made some calls to re{un}map_page dependent on COPY_EMS
|
|
because they are only there to update the logical memory
|
|
* restore_handle_state: unmap pages which were previously unmapped
|
|
* reallocate_pages:
|
|
reunmap only pages belonging to the current handle.
|
|
Fixed a bug: pages above newcount were left mapped.
|
|
* some minor optimizations, fixes and cleanups...
|
|
|
|
Thr Jul 21 1994 JES
|
|
|
|
- Patches from Rainer Zimmermann (zimmerm@Mathematik.UNi-Marburg.DE)
|
|
for time-problems with mfs.c
|
|
- Added procedure to make dosemu.map which is usefull for
|
|
finding where DOSEMU bombs, like kernel. Thanks Daniel :-)
|
|
|
|
Sat Jul 14 1994 JES
|
|
|
|
- Latest enhancements from Markkk.
|
|
|
|
Sat Jul 11 1994 JES
|
|
|
|
- Latest termio.c with keyboard enhancements from Markkk
|

|
|
|
|
* added setlocale-call to dos.c
|
|
* reformatted highscan[] in termio.c
|
|
|
|
Sat Jul 09 1994 JES
|
|
|
|
- DPMI patches from Lutz
|
|
- Pktdriver enhancements by Rob
|
|
- Mouse patch from Douglas Gleichman p86884@tcville.ES.hac.com
|
|
- Changed install dos as per Jochen
|
|
- Windows 3.0 mouse is back.
|
|
- I added insert esc-seq to gettermcap of termio.c
|
|
|
|
Tue Jul 05 1994 JES
|
|
|
|
- Finally... Markkk succeeds where so many of us have failed.
|
|
NCURSES support is here, and I believe to stay :-). It's
|
|
still a bit rough, but it IS. You should truly think about
|
|
getting ncurses-1.8.5.tgz from:
|
|
netcom.com:pub/zmbenhal/ncurses/1.8.5.tgz
|
|
This of course brings color to serial lines and preps for
|
|
many more. I couldn't activate it on a telnet or rlogin
|
|
connect yet. Thanks Markkk, from many of us :-).
|
|
|
|
Sat Jul 02 1994 JES
|
|
|
|
- Finally... interrupt routines are called by functions of
|
|
an array. I'm certain that someone can come up with a better
|
|
method as I'm using 0x100 pointers in interrupt_function().
|
|
|
|
Tue Jun 28 1994 JES
|
|
|
|
- Markkk brings actuall character set to DOSEMU
|
|
when in non-graphics mode ... Yaaa :-). Pease
|
|
read README.ibmset
|
|
- Patch to modify timers done in SIGALRM.
|
|
|
|
Fri Jun 24 1994 JES
|
|
|
|
- Markks console cursor patches, and more speed increses to
|
|
serial stuff.
|
|
- Small change to mfs.c to correct wrong return codes for
|
|
findfirst. Seems t speed up directory searches, but may
|
|
just be my imagination :-).
|
|
- Messed around with SIGILL a bit to try and track down reported
|
|
problem starting DOSEMU for some that causes SIGILL with
|
|
instr of 2e:f7 (cs:div?). No solution yet.
|
|
- Hacked ./init/parse.c a bit to exchange_uids when running
|
|
overide config files. Now /etc/dosemu.conf always runs, then
|
|
overrides can be speced in optional config files.
|
|
Doesn't work yet :-(
|
|
|
|
Tue Jun 14 1994 JES
|
|
|
|
- Next set of patches from Markkk. Major overhaul started
|
|
that is really improving termcap. Way to go Markkk!
|
|
- Alistair has completed in no time flat his automoted
|
|
DANG application. At this time I have NOT included his
|
|
perl script, but hope to soon. Look in ../doc/DANG[.sgml].
|
|
- Michael provides us with an updated DOSEMU-HOWTO in
|
|
.txt,.ps, and .sgml format.
|
|
- Alan has another few patches bringing mice support along
|
|
even further.
|
|
- Tim's IPX patches for 1.1.14 kernels +.

|
|
support.
|
|
- Alessandro Rubini (rubini@ipvvis.UNIPV.IT) patches to make
|
|
Makefiles inherit important common include directory paths.
|
|
- By suggestion from Jon Tombs, make default inb return 0xff
|
|
and the creation of tempdir be strdup'ed incase it's freed
|
|
by a config request.
|
|
- Changed CNTR timers to count UP by 0x2221 instead of down.
|
|
- Changed a compare in xms.c according to Scott Buchholz.
|
|
|
|
Thu Jun 02 1994 JES
|
|
|
|
- Patches from Rob including updates to s3 code.
|
|
- Daniels idea about malloc problem worked into emu.c by
|
|
moving where scrbuf is allocated. Wonder why it was allocated
|
|
where it was.
|
|
|
|
Sun May 29 1994 JES
|
|
|
|
- Stuck in a fix for DIR a: error. It's a KLUDGE for now, but
|
|
I hope it will show where the error is.
|
|
|
|
Thr May 26 1994 JES
|
|
|
|
- More mods to int_queue_run(). Changed where set_leds() is
|
|
called.
|
|
- Moved int.h and int10.h to emu.c as that is where do_int()
|
|
is called mostly now.
|
|
- Scott's latest patches against 1.0.x & 1.1.x
|
|
- Rob's patches to remove linpkt from DOSEMU tree.
|
|
|
|
Sat May 21 1994 JES

|
|
|
- Lutz's latest patches cleaning up DPMI, etc...
|
|
|
|
Thr May 19 1994 JES
|
|
|
|
- Added Scotts proc/self/map kernel-diffs to ./kernel and
|
|
added his patches to bios_emm.c. Bios_emm.c is NOT using
|
|
these by default (See MMAP_EMS in bios_emm.c).
|
|
- Changed run_vm86() use of int_queue_running to *OUTB_ADD.
|
|
- Added extra sti to int10 bios handler.
|
|

|
Wed May 18 1994 JES
|
|
|
|

|
|
- Added diffs from Jochen.
|
|
- Started work on keyboard simplifying. Made lastscan into
|
|
*LASTSCAN a bios area variable.
|
|
|
|
Mon May 17 1994 Jochen
|
|
|
|
- Changed int 8&9 to use a memory location in bios for outb(0x20).
|
|
This nolonger needs to back off to DOSEMU from an outb20. This
|
|
caused vm86() not to return enough to run it's int8's, so
|
|
sigalrm has been modified to be called more often. At the same
|
|
time I now have the pit controllers decremented. Not sure if
|
|
this will be of any use or not. For fun just change the
|
|
TIMER_DIVISOR define at the top of emu.c
|
|
(Hopefully I'll do this for int9 scancodes next)
|
|
|
|
- Fixed bug in EMS coded Sunday that stopped Windows 3.0 from
|
|
properly launching programs.
|
|
|
|
- Makefile fixed to distribute ./ipxutils. Thanks Jochen.

|
|
|
|
Sun 15 May 1994 JES
|
|
|
|
- To EMS added Alternate Map Register Set, OS/E Function Set.
|
|
Windows 3.0 now boots without EMS error(All necessary FNX's
|
|
are supported). Some other cleanup's to EMS including Handle
|
|
Naming.
|
|
|
|
Thr 13 May 1994 JES
|
|
|
|
- Totally changed int_queue_run(). Now only int's requiring
|
|
callback will be forced to.
|
|
|
|
Wed 11 May 1994 JES
|
|
|
|
- Markkk's latest serial.
|
|
- Made ipxutils subdir optionally compile
|
|
|
|
Tue 10 May 1994 JES
|
|
|
|
- Made int08 inline, still need 0x1c to be inline too.

|
|
|
|
* [disk.c disk.h]
|
|
creating the name for the partition-decsription-file moved to
|
|
parse.c, because we need to check the existance of this file there.
|
|
without this file is running further useless. dosemu may hang
|
|
silently.
|
|
|
|
* [emu.c]
|
|
use config.exitearly instead of exitearly and stop dosemu earlier
|
|
when set.
|
|
|
|
* [parse.c config.dist include/mouse.h mouse/*]
|
|
attempt to use cleardtr for some mousesystem/microsoft compatible
|
|
mice. mostly unsuccesful.
|
|
|
|
* [init/Makefile init/parse.c]
|
|
more compiler warnings removed. Error-checking implemented.
|
|
|
|
May 4, 1994 JES

|
|
mice.
|
|

|
|
EmuBat/Sys boot option problem.
|
|
|
|
- First attempt to move net stuff into net subdir and create
|
|
1 ../net.o object for linking.
|
|
|
|
April 27, 1994 JES
|
|
|
|
- If your kernel is of the 1.0.x nature, patch with
|
|
kernel.1.0.x.diff. If your kernel is 1.1.x where x is less
|
|
than 9, patch with kernel.1.1.9.diff. If your kernel is
|
|
1.1.9 patch with kernel.post.1.1.9.diff. Have fun :-)
|
|
|
|

|
February 20, 1994 macleajb@ednet.ns.ca
|
|
|
|
- Wordperfect HOME key stopped working :-( why ?????
|
|
|
|
February 17, 1994 macleajb@ednet.ns.ca
|
|
|
|
- Fixed function 0x23 in mfs.c redirector
|
|
|

|
WordPerfect HOME key problem, and nothing else :-(.
|
|
|
|
February 1, 1994 macleajb@ednet.ns.ca
|
|
|
|
- First layer of terminfo patches in from Corey
|
|
(corey@amiganet.chi.il.us)
|
|
|
|
- Mouse now closes/opens on VC switches. I can now use X and a
|
|
mouse in DOSEMU. Serial is still buggy though.
|
|
|
|
- gorden@jegnixa.hsc.missouri.edu only came on stream less than
|
|
a month ago and has already added a pktdriver interface. Could
|
|
we have another Robert S. here?
|
|
|
|
- dos_helper() int 0xe5 changed to 0xe6 to allow my FCB program
|
|
Direct Access to work.
|
|
|
|
- FCB callouts added to redirector. Lahey Fortran now works,
|
|
as dos Direct Access.
|
|
|
|
- Tim_R_Bird@Novell.COM IPX has been added to dosemu. What's
|
|
Tim's next surprise?
|
|
|
|
- Tim fixed LREDIR.EXE so that emufs.sys no longer has to
|
|
be loaded once at boot.
|
|
|
|
- Tim fixed an error in SIGSTACK.
|
|
|
|
- Int15 0xc0 callout has been modified to deal with DOS programs
|
|
wishing to override scan codes going into the KBD buffer. Still
|
|
needs work.
|
|
|
|
- Allow USAGE to display before default stderr redirection.
|
|
|
|
- Made dos auto-redirect to stderr if no redirection given on
|
|
command line.
|
|
|
|
- Added simple saytime() function to display message and CLOCK
|
|
time.
|
|
|
|
- Modified hard_int routine many times to try and make int 9, as
|
|
well as other ints stay serial and yet nt have to wait for
|
|
program to return to return_address.
|
|
|
|
- Added Corey@amiganet.chi.il.us patches to exchange
|
|
stderr <-> stdout. This is to prepare for terminfo.
|
|
|
|
- Indented all source code according to INDENT.PRO.
|
|
|
|
- Deleted int16 function.
|
|
|
|

|
|
|
|

|
|
outb(20) called by dos programs.
|
|
|
|
- Modified inline int09 to pass ALL keys to int15-4f function.
|
|
|
|
- Added a far return for DPMI call to go protected.
|
|
|
|
- Removed old int16 function.
|
|
|
|
- Changed int08 inside of do_int() to return after being called.
|
|
|
|
- EMS is very close to full 4.0 specs. I've taken the need for
|
|
patching the kernel out at this time so that more folks will
|
|
test EMS. Unfortunately it is horribly slow. Many thanks to
|
|
mikebat@netcom.com (Mike Batchelor).
|
|
|
|
- (Theadore Ts'o's)tytso@ATHENA.MIT.EDU created the booton bootoff
|
|
patch. Now a user can boot from a bootdisk a:, type diskimage,
|
|
and then return control of a: to /dev/fd0. Alright :-).
|
|
|
|
- Added routine to allow Diamond Card to go graphics.
|
|
|
|
- Much effort has been put into keyboard enhancements,
|
|
which have not been that fruitful. Need to have numlock off
|
|
to cut & paste within MSDOS edit, and WordPerfect 5.1 's home
|
|
key does not work as expected.
|
|
|
|
- Keyboard kinda does a REAL int9.
|
|
|
|
- Fixed UMB size 0, and move XMS edx:ebx problem.
|
|
|
|
- Added more SS overflow checks.
|
|
|
|
- Added call in SIGILL to check if illegal op-code is just another
|
|
hard interrupt ending. It calls int_queue_run() and sees if such
|
|
was the case.
|
|
|
|
- Added WORD macro in push/pop functions.
|
|
|
|
- Added check for DPMI far call.
|
|
|
|
- Small ET4000 updates from info from Robert Saunders. Thanks.
|
|
Needs more testing.
|
|
|
|
- Redirector now truncates files properly (with fingers crossed)
|
|
Calls to create_truncate existant files is closer to correctly
|
|
being handled.
|
|
|
|
- Modified findfirst/findnext routine.
|
|
|
|
- Added 0x80 flag to tell DOS it's not lanman redirector.
|
|
|
|
- Poor excuse for an update to work with ../NUL device. Also
|
|
added code to allow mfs.c properly deal the GetRedirection
|
|
with Novell-Lite Printers.
|
|
|
|
- Added lredir using environment vars by
|
|
coosman@asterix.uni-muenster.de
|
|
|
|
Wed Dec 28 00:00:00 1993 jmaclean
|
|
|
|
- Problem with multiple instances of emufs.sys has been destroyed
|
|
I believe.
|
|
|
|
- tytso@ATHENA.MIT.EDU (Theodore Ts'o) has added the ability
|
|
to boot off a bootimage file as drive a:, then release drive
|
|
a: back to dosemu as the actual /dev/fd0 via booton/bootoff
|
|
in autoexec.bat. See ./examples/config.dist for parameters.
|
|
|
|
- As usual the keyboard routines have been dug up more.
|
|
Still MSDOS edit.com needs numlock off to cut&paste. ARG!
|
|
Someone could really make my day if they pointed out what
|
|
I'm doing wrong.
|
|
|
|
- Added video option chipset for diamond for some diamond
|
|
cards, specifically Diamond Speedstar 24x with a
|
|
Paradise/Western Digital chipset. Many thanks to
|
|
patrickm@gas.uug.arizona for putting up with me.
|
|
This does no more than allow 'graphics' for
|
|
this card type.
|
|
|
|
- Overhauled EMS to allow it to work with programs that I
|
|
use. It nolonger requires the mmap.diff patch, so please
|
|
don't use it. I'm just carrying it along because the way Robert
|
|
did EMS mapping was better, and I hope to move back to that
|
|
after folks start beating this version around a bit.
|
|
|
|
- Debugged XMS a bit more to work with UMB's and passing the
|
|
correct XMS address for XMS moves.
|
|
|
|
- Some more messing with ET4000, thanks to Robert alias
|
|
Nils Rennebarth for the ET4000 stuff. Unfortunately I am
|
|
in need of another tester to start relaying bugs. Any takers?
|
|
|
|
- Diffed in patch[1-3]_against_pl3.dif applied:
|
|
- First patch fixed a timer problem mainly.
|
|
- Second patch limited VC switching to left alt key.
|
|
- Third patch almost finishes my changes in keyboard
|
|
routines.
|
|
|
|
- coosman@asterix.uni-muenster.de submitted patches to mfs.c
|
|
which allow lredir to access environment variables like are
|
|
now used in emufs.sys.
|
|
|
|
- coosman@asterix.uni-muenster.de fixed the 15 character limit
|
|
on keybaords, some keyboard extenders should now work,
|
|
yes :-).
|
|
|
|
- coosman@asterix.uni-muenster.de also submitted dumpconf.asm
|
|
to try and fix the multiple emufs.sys instance problem.
|
|
Still unsuccessful, any takers?
|
|
|
|
- Changed dosvga.h to video.h
|
|
|
|
- tytso@ATHENA.MIT.EDU (Theodore Ts'o) aided in getting mfs.c
|
|
to do the ftruncate thing more like DOS. Still not sure if
|
|
it's up to the full 100%.
|
|
|
|
Mon Nov 29 00:00:00 1993 jmaclean
|
|
|
|
* Another update of multiple bugfixes :-).
|
|
|
|
- Keyboard internals have been really rearranged. I'm not sure I'm
|
|
keeping them this way, but now cut&paste problems should hopefully
|
|
go away. Also any program that looked at the bios memory for
|
|
checking ctrl-alt-shift statuses have a better chance of operating.
|
|
Still seems to be some lagging (somewhere).
|
|
|
|
- German keyboard patches thanks to hein@tlaloc.in.tu-clausthal.de
|
|
(Jochen Hein) which should fix that multiple alt key problem a
|
|
couple people have asked about, as well as some incorrect mappings.
|
|
|
|
- As always mfs.c has been updated again to react to another funny
|
|
one on DOS's part. If a file was open write, and actually written to,
|
|
it should be O_TRUNC first. If its just opened for writing, and not
|
|
actually written to, the file should exist as was when closed. ARG!
|
|
The fix is a kludge, and needs some work!
|
|
|
|
- Ross Biro <bir7@leland.Stanford.EDU> gives us some more fixes for
|
|
the redirector, and includes a new toy/option for emufs.sys. Now
|
|
in you config.sys you can add a device statement like:
|
|
- device=c:\emufs.sys \${HOME}/dosstuff
|
|
which will allow you to use your home directory as part of the
|
|
path. Any environment variable can be used.
|
|
|
|
- alan@spri.levels.unisa.edu.au (Alan Modra) fixed some flag setting
|
|
problems in the emulated int13 code.
|
|
|
|
- bde@kralizec.zeta.org.au (Bruce Evans) noticed some initilization
|
|
problems as did -
|
|
|
|
- alan@spri.levels.unisa.edu.au (Alan Modra), so we have changes to
|
|
the registers at boot time, good for some disks that need everything
|
|
just right :-).
|
|
|
|
- And not to forget fin!chip@dg-rtp.dg.com (Chip Salzenberg) who got
|
|
rid of those annoying errors when bison was running.
|
|
|
|
- Makefile has been altered hopefully to cleanup those 'separator
|
|
missing messages'.
|
|
|
|
- parse/parse.c will not be contained in the distribution and should
|
|
limit that parse.tab.h not found error.
|
|
|
|
* From announce0.49pl2
|
|
|
|
- This release has some important changes, actually bug fixes, and some
|
|
new functionality to emufs.sys. (The hardrive redirector) It allows
|
|
us to redirect the redirected drives using a DOS program LREDIR after
|
|
booting, thanks to Tim Bird (Tim_R_Bird@Novell.COM) .
|
|
|
|
- Video switching is still growing, and has had some fixes for Trident
|
|
cards, as well as changing routines for saving and restoring video
|
|
memory above the first bank. ET4000 code is still giving some problems
|
|
so be aware.
|
|
|
|
- Keyboard control has been enhanced using a real time int16 interrupt.
|
|
Thanks Tim. This is important for WordPerfect users, Dosshell,
|
|
Qbasic, and many other problems that have been attributed to keyboard
|
|
problems. This has not been proved to fix the 1 key behind problem
|
|
yet.:-(
|
|
|
|
- Sdh@po.cwru.edu (Scott D. Heavner) has allowed us to specify an
|
|
alternate config file using dos -F'filename' etc with his patches.
|
|
|
|
- A problem writing files in WordPerfect on emufs.sys drives has been
|
|
irraticated.
|
|
|
|
- Dir listings that included the volume label attribute were only
|
|
returning the volume label, and no dir listing. Fixed. Thanks to
|
|
karel@obelix.icce.rug.nl.
|
|
|
|
- Finally the keyboard problem has had another important fix thanks to
|
|
ronnie@lysator.liu.se (ronnie s.) via Robert (gt8134b@prism.gatech.edu)
|
|
that should fix the keyboard behind by 1 problem.

Tue Jul 13 19:54:13 1993 rsanders
|
|
|
|
* Makefile: cleanups...
|
|
|
|
Tue Jul 13 19:24:54 1993 root
|
|
|
|
* cpu.c, cpu.h, emu.c:
|
|
changes for using the new (0.99pl10) signal stacks
|
|
|
|
Wed Jul 7 21:44:51 1993 root
|
|
|
|
* emu.c: hook for parse_config(name);
|
|
|
|
* parse.c:
|
|
added support for ~/.dosrc and parse_config() now takes a filename
|
|
argument to override .dosrc check.
|
|
|
|
Mon Jun 7 20:26:09 1993 (root@hrothgar)
|
|
|
|
* emu.c (char_out): more BIOS-like handling of int
|
|
0x29...character attributes are now reserved, and scrollup now
|
|
uses the attribute from the previous char (needs more work).
|
|
|
|
Fri Jun 4 01:43:39 1993 (root@hrothgar)
|
|
|
|
* cpu.c (find_port): added Andrew's patches diff1-6, which include
|
|
the maskable port I/O. Began fixes to allow ports beyond 0x3ff.
|
|
|
|
Thu Jun 3 23:05:26 1993 (root@hrothgar)
|
|
|
|
* emu.c (ms_dos): fixed up the EmuSys and EmuBat directives. They
|
|
now take string arguments.
|
|
|
|
Thu May 27 21:38:08 1993 (root@hrothgar)
|
|
|
|
* bios_emm.c (bios_emm_init): moved into dosipc.c: memory_setup().
|
|
Now checks that /proc/self/mem is mmap()able, and turns off EMS
|
|
support if it isn't.
|
|
|
|
Wed May 26 01:09:23 1993 (root at hrothgar)
|
|
|
|
* moved 0xE000 segment routines to 0xF000. also changed reboot
|
|
code to use inte5, ax=0xffff
|
|
|
|
Tue May 25 01:41:53 1993 (root at hrothgar)
|
|
|
|
* added early support for the EmuSys and EmuBat directives, which
|
|
remap CONFIG.SYS to CONFIG.EMU and AUTOEXEC.BAT to AUTOEXEC.EMU.
|
|
This works now, but I'm not sure when I should disable it.
|
|
|
|
Mon May 24 21:50:33 1993 (root at hrothgar)
|
|
|
|
* added CMOS checksum.
|
|
|
|
* dosemu 0.49 released!
|
|
|
|
Fri May 14 00:41:08 1993 (root at hrothgar)
|
|
|
|
* cleaned up the int10h ah=9/0xA calls...they now work correctly
|
|
except for possible bounds checking.
|
|
|
|
* made floppies safe, but slow...work on this.
|
|
|
|
Wed May 5 02:18:23 1993 (root at hrothgar)
|
|
|
|
* added mouse support and console switching even in graphics
|
|
mode.
|
|
|
|
Tue Apr 20 00:49:07 1993 (root at hrothgar)
|
|
|
|
* added DMSG_PAUSE for pausing the parent...
|
|
|
|
* fixed a lot of int10() problems, including cursor positioning
|
|
and int10h 0xa/0x9.
|
|
|
|
Fri Apr 16 08:58:43 1993 (root at hrothgar)
|
|
|
|
* added VGA BIOS support...user vgaon.com to allow it, vgaoff.com
|
|
to stop it.
|
|
|
|
Wed Apr 14 03:44:36 1993 (root at hrothgar)
|
|
|
|
* now have mfs.c updated all the way to diff9, which has multiple
|
|
drive support...(not my doing!). also translated linux.asm into
|
|
emufs.S.
|
|
|
|
Mon Apr 12 22:08:39 1993 (root at hrothgar)
|
|
|
|
* added the 1-second tick in dosipc.c. the child gets a SIGALRM
|
|
every second, which child_tick() handles. currently only calls
|
|
print_tick().
|
|
|
|
Tue Apr 6 00:20:05 1993 (root at hrothgar)
|
|
|
|
* stold the Mach DOS emulator's UMB routines. PCShell no longer
|
|
crashes, PKZIP now uses it. PKZIP 2.04e won't use EMS :-( and
|
|
neither will debug.
|
|
|
|
* ported bios_emm.c (EMS emulation) from the Mach DOS emulator. It
|
|
relies on my kernel hack of mmap(/dev/selfmem). Works pretty well,
|
|
emulates EMS version 3.2.
|
|
|
|
* applied diff1,diff2,and diff3 from Andrew Tridgell. MFS works
|
|
better, faster. MFS also adjusts for being run suid root. The
|
|
default interrupt (0xfe) conflicts with Turbo Debugger. I suggest
|
|
a change to 0xe5.
|
|
|
|
Thu Apr 1 03:08:22 1993 (root at hrothgar)
|
|
|
|
* translated the bootsect.S code for as86. This is nice for
|
|
general interest, and for the distribution hdimage (which requires
|
|
fdisk /mbr to fix it, by the way).
|
|
|
|
Wed Mar 31 01:00:37 1993 (root at hrothgar)
|
|
|
|
* integrated Andrew Tridgell's port of the Mach mfs redirector.
|
|
Seems to work okay, if not blazingly fast. Sure beats linux.exe.
|
|
|
|
* changed VIRT_SCREEN_BASE and INIT_VIDEO_MODE for MDA to actually
|
|
show MDA mode 7 and base of 0xb0000.
|
|
|
|
* added PARTITION type. only works with /dev/hd?1. relies upon
|
|
the file "/etc/dosemu/partition" to be the first sector (Master
|
|
Boot Record) of /dev/hd?.
|
|
|
|
Tue Mar 30 02:51:33 1993 (root at hrothgar)
|
|
|
|
* changed disks.c a lot, added the IMAGE file header code (to
|
|
auto-detect geometry from an image file).
|
|
|
|
Mon Mar 29 00:47:41 1993 (root at hrothgar)
|
|
|
|
* added the int 0x2f, ax=0x1680 "give up time slice" function.
|
|
does a usleep()...is this best? thanks to Andrew Tridgell.
|
|
|
|
* changed disks.c to simply accept FLOPPY_A as defined
|
|
|
|
* changed -f option to take an argument
|
|
|
|
Sun Mar 28 02:07:50 1993 (root at hrothgar)
|
|
|
|
* wrote dosconfig.c to replace dosconfig.sh.
|
|
|
|
* changed the int16h ah=0x55 to return eax=0 for MS-WORD 5 (check
|
|
this with Andrew Tridgell).
|
|
|
|
* fixed up some of the CONFIGURATION (int 11h value) stuff. see
|
|
emu.c, config_init()
|
|
|
|
Mon Mar 8 00:37:07 1993 (root at hrothgar)
|
|
|
|
* added dosconfig.sh for "make config", rearranged Makefile to be
|
|
a little safer. It tries to keep the user's config.h updated, but
|
|
not to recompile too often. (dosconfig.sh uses awk)
|
|
|
|
* cleaned up get_video_ram()...Turbo debugger 3.0 now works, at
|
|
least the video stuff does.
|
|
|
|
* added some fixes so that leavedos() will timeout after 3
|
|
seconds or so, but I still need to find out why/where it hangs.
|
|
|
|
* added memory.h and video.c. added "make dep" to Makefile.
|
|
|
|
Sun Mar 7 15:05:10 1993 (root at hrothgar)
|
|
|
|
* added an ugly hack for multiple screen pages...nasty. works okay
|
|
for Turbo Debugger 1.0, though. also began marking hacks with
|
|
XXX...most everything new&old is a hack, sadly enough. termio.c &
|
|
emu.c need to be robbed of the screen functions, which will be put
|
|
in screen.c. also the emu.h and termio.h headers...clean the
|
|
get_video_ram & put_video_ram stuff...
|
|
|
|
Thu Mar 4 01:23:04 1993 (root at hrothgar)
|
|
|
|
* added the proper set-iflag-after-instruction STI emulation. it
|
|
doesn't seem worth it, so I disabled it be default (define
|
|
PROPER_STI in cpu.c or the Makefile to get it working).
|
|
|
|
* got the HMA working perfectly. moved the IPC_RMIDs into
|
|
memory_shutdown(), called by stop_dosipc, so that the HMA area,
|
|
which isn't always attached, wouldn't go away unexpectedly.
|
|
|
|
* used krishna's new ipcdelta stuff (the SHM_REMAP flag) to make
|
|
the low page shared, too. I should break this out of the main
|
|
segment1. verified that it works.
|
|
|
|
* added SIGCHLD handler, fixed up the DMSG_ACK situation. still
|
|
need to design a rational, interrupt-like protocol for this.
|
|
|
|
* added shared memory to dosemu. I haven't gotten Krishna's new
|
|
stuff yet, so I don't share the first page (I NEED TO!). 2 segments,
|
|
one from 0x1000-0x9ffff, the other 0xc0000-0xfffff. Because of
|
|
stupid mmap(), I can't share the segment from 0xa0000-0xbffff, as
|
|
mmap() needs memory under, and IPC can't have memory under.
|
|
|
|
Tue Mar 2 02:07:57 1993 (root at hrothgar)
|
|
|
|
* apparently, whatever badness in DOS 5.0 that caused the SIGSEGV
|
|
when booting has gone away, or I've fixed it, so I took the
|
|
boot_in_progress checks out (partially, I'm a little wary). We'll
|
|
see how it goes.
|
|
|
|
* made the child process munmap() everything from page 2 (address
|
|
4096) to the page before LIBSTART. this should cut down on memory
|
|
usage a little, as well as make attaching shm a little easier.
|
|
still doesn't fix first page problem, but Krishna is doing that.
|
|
|
|
* changed the format of the DOS HELPER function to show interrupts
|
|
(now takes low int in BH,high int in BL). Also added a parameter
|
|
to show_ints(). also added -2 option for 80286 flags emulation.
|
|
(real-mode 80286 keeps upper 4 flag bits (15,14,13,12) clear.
|
|
|
|
* added two new switches, -3 and -4, that allow you to choose 386
|
|
or 486 "emulation"...this currently only changes the behavior of
|
|
the AC (alignment check) bit of EFLAGS, but since that IS the
|
|
Intel-recommended test...I need to add emulation for BSWAP, XADD,
|
|
and CMPXCHG instructions for 386 users running in 486 mode (just for
|
|
kicks :-). I wonder if PKZIP 2.04 is much faster in 386/486 mode...
|
|
|
|
Mon Mar 1 01:35:53 1993 (root at hrothgar)
|
|
|
|
* added code to keep virtual IOPL, NT, bit15 of eflags register.
|
|
this means I also have to interpret the 0x66 and 0x67 instruction
|
|
prefixes (32-bit operand and address, respectively). this must be
|
|
done in sigsegv()...it's just ignored now
|
|
|
|
* split dosemu into 2 processes, one of which currently only
|
|
monitors keypresses. I use UNIX domain sockets--pipe() returns a
|
|
uni-directional pipe :-(
|
|
|
|
* tried to speed up clear_screen() for non-console video.
|
|
|
|
Thu Feb 25 21:19:10 1993 (root at hrothgar)
|
|
|
|
* fixed show_regs() to display an iflag-adjusted eflags. I should
|
|
make access functions to _regs.eflags so that "virtualized" bits
|
|
are always handled correctly.
|
|
|
|
* fixed iflag/IF handling...Matthias had forgotten to adjust iflag
|
|
on popf and iret. Silly boy. I wasn't doing much better, testing
|
|
IF directly from the _regs.eflags after return from vm86(), which
|
|
of course corresponded to the system IF...someone should write a
|
|
virtual-8086 mode tutorial!
|
|
|
|
Wed Feb 24 11:33:59 1993 (root at hrothgar)
|
|
|
|
* fixed the key-repeat bug.
|
|
|
|
Tue Feb 23 01:36:17 1993 (root at hrothgar)
|
|
|
|
* well, the ugliness with indirect far calling can be
|
|
skipped...however, I can only get pcshell to work with the mouse,
|
|
and it doesn't use callbacks! added lctrl+rctrl+capslock = toggle
|
|
kayboard mouse...arrow keys are direction, home is left and end
|
|
is right button.
|
|
|
|
* made the first brain-dead changes for mouse support.
|
|
|
|
Mon Feb 22 16:26:17 1993 (root at hrothgar)
|
|
|
|
* cleaned up the show_regs() a bit, better display of flags, shows
|
|
10 bytes before and after CS:EIP.
|
|
|
|
* added the define FAST_BUT_WRONG29, which, if defined, makes
|
|
int29 fast char output faster, but makes programs that hook int29
|
|
fail. ANSI.SYS is one of these. I leave FAST_... defined, as
|
|
ANSI.SYS doesn't work now anyway.
|
|
|
|
* added the extended (32-bit) XMS 3.0 API. cleaned up xms.c to be
|
|
a little more 32-bit clean (i.e. doesn't fudge upper 16 bits of
|
|
register if it's not supposed to). Added the macros LWORD() and
|
|
HWORD() to emu.h...
|
|
|
|
Sat Feb 20 17:43:50 1993 (root at hrothgar)
|
|
|
|
* added Bill Bogstad's (bogstad@cs.jhu.edu)
|
|
auto-hd-geometry-detect code. It seems to work okay.
|
|
|
|
Thu Feb 18 01:38:21 1993 (root at hrothgar)
|
|
|
|
* RELEASE: released these changes as 0.48.patch1. Peter Macdonald
|
|
(pmacdona@sanjuan.uvic.ca) says he'll incorporate this into his SLS.
|
|
|
|
* changes NUM_HANDLES for XMS to 64. took out handle_mask.
|
|
|
|
* added the screen-buffer-and-compare code to restore_screen().
|
|
this ought to really speed up the non-console users
|
|
|
|
Wed Feb 17 15:40:54 1993 (root at hrothgar)
|
|
|
|
* fixed up the Makefile to make libemu start at 1 GB... this is
|
|
really really important, as the dosemu0.48 distribution's MAX_XMS
|
|
of 3072 could overrun into libemu...I don't know why it works this
|
|
way, but it does (actually, I do know why, I just don't know why
|
|
sbrk() lets you move into a shared lib). Anyway, now xms.c checks
|
|
that you have space left for MAX_XMS (at compile time, will have
|
|
to be dynamic-ized to run time XMS size setting)
|
|
|
|
* removed the check for console_keyb before calling
|
|
PollKeyboard...non-console users deserve a keyboard, too!
|
|
|
|
Tue Feb 16 00:29:58 1993 (root at hrothgar)
|
|
|
|
* cmos RTC now returns values in BCD if appropriate (usually is)
|
|
|
|
* fixed the keypad number keys. forgot to put scancode in upper
|
|
byte. also fixed the F11 and F12 keys.
|
|
|
|
* added man page, and the rest is history.
|
|
DOSEMU 0.48 DISTRIBUTION
|
|
|
|
Mon Feb 15 00:24:50 1993 (root at hrothgar)
|
|
|
|
* added all the ctrl and alt cursor keys.
|
|
|
|
* added the files cmos.c and cmos.h. these will eventually
|
|
contain all the CMOS values needed and provide CMOS real-time
|
|
clock and alarm support. current code covers time/date, disk
|
|
setup, memory size, CMOS status.
|
|
|
|
Sun Feb 14 16:50:28 1993 (root at hrothgar)
|
|
|
|
* put the special_nowait call into read Extended keycode also.
|
|
I've really gotta verify this.
|
|
|
|
Sat Feb 13 15:26:20 1993 (root at hrothgar)
|
|
|
|
* uh, fixed the XMS EMB alloc. problem. I swear I checked for
|
|
this when I first had problems, but apparently not...I was
|
|
malloc()ing the actual K size, instead of the K size * 1024.
|
|
|
|
* added some XMS functions, made the XMSControl entry point
|
|
conform to the spec (for hookability).
|
|
|
|
Fri Feb 12 14:19:30 1993 (root at hrothgar)
|
|
|
|
* put the 101-key keyboard flag in the BIOS
|
|
|
|
* Added the timer_tick() routine. this fixes a LOAD of
|
|
stuff...4DOS beep lockup, 4HELP, Norton utilities, checkit,
|
|
autocnf, bunches and bunches of stuff, basically. This still
|
|
needs a LOT of work, like keeping track of round off error, higher
|
|
frequency, but it'll do for now.
|
|
|
|
Thu Feb 11 01:53:27 1993 (root at hrothgar)
|
|
|
|
* changed ReadString to accept almost any characters. I'm still
|
|
not sure about the ones below space.
|
|
|
|
* char_out now treats \n as \n\r. I wonder about this. also,
|
|
ctrl-c checking is done a little more properly (look for dos_ctrlc())
|
|
|
|
* added the hold-alt-and-type keypad numbers entry method. still
|
|
need to add alt/shift/ctrl-cursor keys.
|
|
|
|
Wed Feb 10 13:08:05 1993 (root at hrothgar)
|
|
|
|
* WordPerfect works perfectly now :-). almost.
|
|
|
|
* added Rshift-scrlock for int8, lshift-scrlock for int9. funny
|
|
thing is, these work better than the flags. makes me wonder about
|
|
the whole signal handler thing, and maybe I should check the IF.
|
|
|
|
* added the -K flag. sorta makes QBASIC/EDIT work. if I use the
|
|
-t switch (timer int), then msdos will crash eventually with a GP
|
|
fault on 0xe8.
|
|
|
|
Tue Feb 9 15:45:54 1993 (root at hrothgar)
|
|
|
|
* XMS can now allocate the HMA and a single UMB at 0xc000. I
|
|
really need to make sure that 0xc000 isn't BIOS-mapped, but I'm
|
|
just playing now, anyway. This is fun! I can put dos=high,umb in
|
|
my config.sys and get 702K posible executable size! (with -m 720)
|
|
|
|
* began the XMS stuff. Have a driver that can mark its presence
|
|
and claim no HMA. :-)
|
|
|
|
* fixed the dir /w problem by allowing int 21h to do its own char
|
|
out. however, I found an anomaly in the get video combination
|
|
code. I can return 4 (color EGA), but not 8 (color VGA). If I
|
|
do, qedit freaks and puts the menu up off the screen as if the video
|
|
memory started at 0xb000:0000. The same thing happens if I change
|
|
BL in video subsystem.

|
|
|
|
* this (or herabouts) is RELEASE 0.47.7
|
|
|
|
* fixed the heavy-load miss characters thing. The keybuffer code
|
|
Stephen Tweedie gave me would advance the buffer even if ReadKeyboard
|
|
was called with wait=TEST.

|
|
|
|
* okay, fixed the lost characters thing for real: Matthias' int29h
|
|
handler (fast DOS tty output) was calling int 10h/ah=e. int 29h
|
|
output always goes to the current screen, and Matthias wasn't
|
|
taking that into account.

|
|
|
|
* i know why...I'm doing that damn WAITACTIVE ioctl(). damn damn
|
|
damn! I see no way around that. (later note: it might in fact
|
|
be the fact that I was often deleting libemu out from under
|
|
dosemu's feet with rm -f, and now that I've stopped that,
|
|
everything's better. Should I keep the ioctl queue?)
|
|
|
|
* well, it seems that my ioctl queue hasn't stopped the kernel
|
|
panics. here's what I get (raw keyboard mode):
|
|

|
|
|
|
* well, pkzip 2.04e uses int10h/ah=e with a seemingly random
|
|
screen page. PC-DOS 4.01 seems to do the same thing. so, in my
|
|
infinite wisdom, if it writes to a screen page > 7, i make it
|
|
write to the current screen page. this is probably wrong, but it
|
|
works for pkzip 2.04e.
|
|
|
|
* fixed the PollKeyboard() thing, I think. I use a "queue" for
|
|
ioctl()'s started from within an interrupt handler. this is
|
|
nasty, but it'll have to do. I can make this a lot pretier.
|
|
|
|
* AAARRRRRGH! PollKeyboard() was crashing the emulator (kernel
|
|
panics and such) because I was using select()...and looky here,
|
|
pg. 278 of the Stevens book, select() is NOT listed as one of the
|
|
reentrant functions. I'm a fool. A FOOL, I tell you!
|
|
|
|
* these changes I will call dosemu0.47.5
|
|
|
|
* also added choice of PHANTOMDIR and VIDEO_CARD to the Makefile.
|
|
VIDEO_CARD only has effect if it is set to MDA: the
|
|
PHYS_SCREEN_BASE will then be set to 0xb0000 instead of 0xb8000.
|
|
|
|
* Now you can choose your RAW keyboard nationality in the Makefile
|
|
(like with a kernel compile). Gotta clean this up later with a
|
|
keymaps subdir, and all the keymaps therein. Also noticed that
|
|
when 4dos freezes up during a beep, ctrl-break (in RAW mode, of
|
|
course), fixes it :-). Added these keys to RAW (-k) mode:
|
|
ctrl-alt-pgup ... exit the emulator
|
|
ctrl-alt-pgdn ... "reboot" the emulator (not recommended)
|
|
ctrl-break ... as in DOS
|
|
ctrl-scrollock ... show first 0x30 interrupt vectors
|
|
alt-scrollock ... show registers
|
|
for some reason, keypad cursor keys (pgup/pgdn/delete) when
|
|
combined with the ctrl-alt keys will cause nasty things to happen.
|
|
Things like kernel panics, hard system reboots, etc. Is this my
|
|
fault, or Linux's? (I'm sure it's mine, but I can't figure out how)

|
|
|
|
* Added some elementary key-polling in sigalrm() with
|
|
PollKeyboard(). This works okay for now, but I really need to make
|
|
in general purpose (not just for console_keyb) and make the key
|
|
buffer use the BDA for real. Then we've got keyboard about done,
|
|
except for the multi-national keyboard maps.
|
|
|
|
* Added Stephen Tweedie's small patches for insert-key into
|
|
keyboard buffer (InsKeyboard). This needs to be rewritten to use
|
|
the real BDA queue.
|
|
|
|
* made the parse-debugflags kinda recursive, so a and 0 don't
|
|
terminate the parsing. This allows for handy option strings like
|
|
"-a+v" or "0+v" for debugging just video.
|
|

|
Tue Feb 2 15:21:59 1993 (root at hrothgar)
|
|
|
|
* note that DOSKEY works now! Nathan says it didn't before. Oh,
|
|
well. I thought it didn't.
|
|
|
|
* cleaned up the debug-msg flags a bit. now the -D option
|
|
specifies a list of options. also cleaned up the int-revectoring
|
|
a tad. moved a little of the stuff into emu.h (a lot more needs
|
|
to go)
|
|
|
|
* added the -f option to flip A: and B: floppies. I also have the
|
|
-B flag to boot from the b: drive, but I don't think DOS will ever
|
|
be happy with that. might take it out before release.
|
|
|
|
Mon Feb 1 23:53:52 1993 (root at hrothgar)
|
|
|
|
* NEED to find out what int 16h/ah=0x55 does. it seems to control
|
|
timeout for get_char (int 16h/ah=1), and is necessary for dosshell
|
|
and qbasic (which freeze occasionally otherwise).
|
|
|
|
* added some wacky int-revectoring code. all but int 16h is broke
|
|
right now, and that is even special-case, too.
|
|
|
|
Wed Jan 27 00:21:06 1993 (root at hrothgar)
|
|
|
|
* fixed problem with CloseKeyboard() sometimes restoring flags
|
|
that had never been read. now, kbd_fd==-1 at startup, as it should.
|
|
|
|
* fixed time problem - now DOS time is set properly at boot to be
|
|
in sync w/Linux's clock. After that, DOS can change it.
|
|
|
|
* moved the port_[out,in] functions to emu.h
|
|
|
|
* fixed a problem in get_leds() arising from the fact that &= is
|
|
not the same operator as &. silly me. now it works.
|
|
|
|
Tue Jan 26 16:48:31 1993 (root at hrothgar)
|
|
|
|
* well, had to put ioperm()s to disable the emulator's I/O
|
|
permissions before I re-enter the vm86() call. (of course, the
|
|
vm86 "task" inherits the emulator's ioperms). This means that if
|
|
I'm not careful, I may leave an I/O port open to DOS :-(.
|
|
|
|
* Added two options: -N exits the emulator before booting DOS (but
|
|
after all the initialization), and -V allows VGA video. This
|
|
presently only includes the changing of the blink attribute bit to
|
|
the high intensity background bit, but it will one day also enable
|
|
VGA graphics.
|
|
|
|
Mon Jan 25 22:19:20 1993 (root at hrothgar)
|
|
|
|
* the linux.exe problem was found: linux.exe will fail if there
|
|
are more than 2 floppy drives defined. i defaulted the number of
|
|
floppies and hard drives to 2 each; this is changeable by the -H
|
|
and -F options.
|
|
|
|
Thu Jan 21 21:10:06 1993 (root at hrothgar)
|
|
|
|
* filled the highscan[] table for all chars <= 0x80 (ASCII). the
|
|
rest are alt-chars (from a terminal's point of view, META at least).
|
|
|
|
* note that the below change required that I no longer open
|
|
/dev/tty, but use STDIN_FILENO and dup() that. whatever that implies.
|
|
|
|
* fixed the console-video/keyb code. dosemu can now detect if you
|
|
are on a console, and refuse to run if not. it also retrieves the
|
|
console number for future use. (very system-dependent checking of the
|
|
major/minor numbers! this is dangerous! if dev_t changes from 16
|
|
bits, this breaks.) console_video console switching should now be
|
|
completely safe, thanks to WAITACTIVE. currently, it blocks until
|
|
the dos console is current. I might want to change this so that
|
|
it just doesn't map it if the console isn't current--using
|
|
GETSTATE (and wait for later acquire_vt() calls to do so.)]
|
|
|
|
* made the int13 disk-sensing functions more sensible. also made
|
|
the dp->tracks, dp->heads stuff orthogonal (for some reason,
|
|
matthias had made exceptions for floppys??). You can now
|
|
format/unformat a floppy, as well as a floppy disk image. added a
|
|
default CMOS type to the disk table struct.
|
|
|
|
Sat Jan 16 10:28:23 1993 (root at hrothgar)
|
|
|
|
* fixed alt-numkey bug in termio.c. for some reason, alt-numkey
|
|
scancodes get bumped up by 0x76. also fixed alt-- and alt-=
|
|
|
|
* can't find bug that causes repeated extended keystrokes to kill
|
|
the emulator: to find it, run tv.com on some file, go the bottom,
|
|
and press & hold pgdn. bam, crash.
|
|
|
|
* fixed int21h, ah=1,7,or 8 problem with extended keycodes;
|
|
(was supposed to return 0 first, then scancode on next call).
|
