first of all let me clear what you want first. You want win 2k and win 98 to share files? I think you can do that cause I think I have a few programs that I share between Win 98 and Win 2k. So what you need to do is when you install a program A for example on the Win 98, point that to the data partition and so when you want to install program A on Win 2k you just point that also to the data partition. To do that, when you want to do installation, use custom install. One more thing is you must make the data parition as fat32. If that's what you want then I think I give you the answer but if that's not what you want, ask me again and I will try to help you again.
