It sounds like your current XP system is formatted to NTFS, which is why
your DOS-based programming won't work.
Win98SE will run it just fine, and is way better than Win95 (avoid WinME).
Windows 2000 is typically run on NTFS format, so that would not help you.
Probably simplest solution would be to set up a dual-boot feature. Do a
Google search for "dual boot XP Win98" or something like that, there is
plenty of info out there. Microsoft's Knowledge Base (on their website)
also has info on how to do this.
