Better Yet, use a virtual pc.
It's Commercial But arguably the best PC Emulator VirtualBox
OpenSource Project - Seems very nice alternative to VmWare DosBox
Not a PC Emulator, but a DOS emulation layer, plenty of ppl use this alternative.
Personally I prefer VmWare/VirtualBox. Cuz I like to play with linux also. so having the capability of loading a different OS in an emulated PC works great for me.
for VmWare/VirtualBox u will need the OS installation disks/cds. Install yer OS, than install the game. Mind u, u will lose a lot of speed for the emulation. However u are running DOS, and DOS proggies dun need the high end power of today's systems.
