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.
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.
