would you knowingly put yourself through torture? i hope not, so keep the win2k install, leave win98se for dead, the thing is a shit hole, piece of crap. use win2k, it is the most stable windows OS yet to come out of that evil bastard of a company. The time you will save having to rerecord stuff from damaged HDs caused by win98 carshes will be saved in the $150 a delta 44 will cost used. believe me, win98 is an obsolete piece of software. Microsoft would like to have everyone believe that win2k is obsolete as wel, but its not true. Anyone developing on a windows platform uses it. XP is nothing new over win2k except for home multimedia features and standard drivers, but not pro-audio drivers. stay with win2k and a new card, you will kick yourself to death if you use win98.
