DOSEMU http://dosemu.sourceforge.net/ or DOSBox
http://dosbox.sourceforge.net/ might be more appropriate for running
timing critical DOS applications. It's been a while since I've been in
the loop with DOSEMU but IIRC since Linux takes over the BIOS clock and
runs it at a different clock rate it has to emulate the 18.2ms(?)
interrupt call ... DOSBox probably does the same thing.
The difference between the two is DOSEMU is a generic DOS emulator and
DOSBox is a DOS emulator tuned for running Games.
