Are over now. With 98se I was having lots of freezes and only way out was reset-button. I tried different drivers, directX:es, moving cards to diff.slots...
I was so tired I almost cancelled my subs. but then last hope W2K helped me out from my misery
Works fine with PIII 700@933,256,Dx8A, SB-live and Herc. GfMX2
