I need help... I loaded 702 bios and now OS will not load it saids it can not find hard drives? I am using Vista 64 and repair console doesn't see a hard drive installed. I tried reinstalling windows and it will install fine untill it has to reboot, an then I get a boot error. I have tried reloading both XP and Vista and tried to reflash to bios 0511 which I was using. I have tried bios 0701, 0702, and 0703, I have 0603 currantly installed. I loose hard drives after every install now. I have ran all the test on my drives and they pass and raid controller passes all test also. I feel like my MOBO is FUBAR again, the on boad chip is corrupt. I left battery out of MOBO for 24 hours also it made no difference, so should I RMA MOBO again or is my propblem else where ya think?
