For all you oldies-lovers that don't feel like going tru a huge config process for playing a dos-based game: virtual pc!
Basically; you're "creating" a virtual HD on your physical HD, and then install an OS on that virtual HD
WITHIN your main OS. (assuming winxp)
I've been doing it for a while now, have a virtual pc running win98SE in my WinXP, and i've been having some good fun with my dos-based games so far, w00t!
It's a microsoft product and can be tried out for free for some 40 days, so check it out:

P.S. i found something really funny while searching about on this:
sure thing. lol.
