increasing hard drive size

i am trying to go from windows98 to xp. With my win98 i had 2 hard
drives, 1 6gig the other is a 120gig(this one is partitioned 3 times
20gig each, i could not get more than this, i assume because of win98)
i am now on xp but can only get 30 gig on the 120gig drive, i cant see
the other 2 partitons. i read somewhere if i use fat32 i can only get
30gig partitions, is this true? i dont want to use NTFS because of
some of my older games. i am running an old computer (pentium 700) it
has 512 mb of ram. if i install xp on the 6gig(it would not let me do
this because of the i386 crap) could i then format my 120gig to be
120gig or do i still have to partition it? if so do i have partitioned
4 times to get the whole 120gig? the data on both disks i dont care
about because i already backed up what i needed. if anyone knows how
to fix thanx.
