I am running win98se & winxp on the IWILL XP333 pure board. Love it! Didn't at first, coming from a long line of fic,abit, epox boards all with VIA crapsets. Choose the Raid ver: from newegg.com $109 even if ya don't use raid this gives you ata/133 hipoint controler for the new maxtor hard drives. Just screams, plus the raid gives ya two more drives!
