fat 32..
i have used bolth extensivly, and havent noticed a difference. if you format in NTFS, than you can use a boot disk or boot off the win98 cd rom if something were to happen to you computer to fix/get files off of it. right now, my 2k partition is formated in NTFS, and it is a pain. i dual boot with 98, and it is hard to swap files back and forth because 98 cant read NTFS.
do what ya want, but i would go with fat 32.
