I have been happily using XP for several months, but I need to reinstal Win98
because some of my older games will not work at all under XP (even with an
emulator like DosBox or VDMSound).

Here's my current HDD setup:

HDD0: 40 GB, single partition (C, bootable, NTFS, where XP is.
HDD1: 30 GB, partitioned at D:-G:, all FAT32. D: is where I plan to put Win98.

1st off, is it possible to reinstall 98 without ripping out XP?
2nd, should I even do it?
