|
## Running
|
|
|
|
Just type
|
|
```
|
|
dosemu
|
|
```
|
|
to run an emulator.
|
|
|
|
Use
|
|
```
|
|
dosemu -E <dos_cmd>
|
|
```
|
|
to run `<dos_cmd>` and exit (add `-T` to not exit).
|
|
|
|
Use
|
|
```
|
|
dosemu -K <unix_dir> -E <dos_cmd>
|
|
```
|
|
or
|
|
```
|
|
dosemu <unix_full_path> -- <dos_prog_args>
|
|
```
|
|
to run DOS programs from unix directory.
|
|
|
|
If you want to run the DOS program from a DOS directory, use this syntax:
|
|
```
|
|
dosemu -K :C:\\games\\carma -E carma.exe
|
|
```
|
|
This will run `carma.exe` from `c:\games\carma`. Note the leading colon
|
|
after `-K`: it means that the DOS path, rather than unix path, is specified.
|
|
You can actually specify both paths:
|
|
```
|
|
dosemu -K ~/dosgames:carma -E carma.exe
|
|
```
|
|
This creates the DOS drive for `~/dosgames`, then chdirs to `carma` and
|
|
runs `carma.exe`.
|
|
|
|
## Configuring
|
|
|
|
Per-user configuration file can be created as `~/.dosemu/.dosemurc`.
|
|
Add your custom settings there.
|
|
Look into the global configuration file `/etc/dosemu/dosemu.conf` for
|
|
existing settings, their descriptions and default values, and modify
|
|
the local config accordingly. `$_hdimage` is probably the first setting
|
|
to look into, as it configures the host fs access.
|
|
|
|
Create `c:\userhook.sys` and/or `c:\userhook.bat` files to customize your
|
|
boot sequence. userhook.sys can contain the `config.sys` directives and
|
|
`userhook.bat` can contain custom boot commands.
|
|
|
|
Drive `C:` is usually located at `~/.dosemu/drive_c`. You can add DOS
|
|
programs there. Or you can run `dosemu -d <unix_dir>` to mount the
|
|
`<unix_dir>` as a new DOS drive.
