I just recently wanted to do the same thing, what I done was made an Image of XP and put it on another partition, then booted with a Win98 floppy and installed 98, and then I installed XP. Right after XP was done installing I ran the Image. There was one or two small programs I had to reinstall, but it work great for me. Here are some of the tools I used. If I’m not mistaking if your partition is NTFS you can still install Win98 and it will change it to FAT32, if not partition magic can change NTFS to FAT32. If you want to use Win98 you can change the BIOS to boot from the CD first, so all you may need is the Drive Image, that’s if you want to save you current XP set up.
