Just bite the bullet and move to XP
See above: Yeah, thanks, that's amazingly useful. Especially considering I have 98 installed strictly for DOS stuff. Good job.
the XP command prompt will NOT run many of the older DOS games properly, since it prohibits direct hardware access. Win95/98/ME have much better compatibility with old games than XP does.
That said, as Mr. Picklesworth pointed out, you may want to take a look at DOSBOX on XP.: http://dosbox.sourceforge.net/news.php?show_news=1
Essentially it's a DOS emulator for windows, which supposedly has a pretty good track record.
from the page above: DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, modem, etc., necessary for running many old DOS games that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows 2000, Windows XP, Linux and FreeBSD. However, it is not restricted to running only games. In theory, any DOS application should run in DOSBox
