I have an Abit KR7A-RAID mobo and I recently purchased an XP2200 CPU after researching and discovering that Abit offers a BIOS update that specifically supports XP2200. I downloaded and installed the new BIOS before removing the old XP1900 which was running fine. I installed the XP2200 and cleared the CMOS with the jumper. The XP2200 wont boot. I tried lots of things and no success. Tried the XP2200 in a cheap Amptron MB without even updating the BIOS and it worked fine. Anyone else had problems with XP2200 and KR7A-RAID?
