That is probably your problem. Enalbe EVERYTHING the first time around THEN start disabling. For some reason, Asus has the SATA ports and RAID enable for those ports BACKWARDS. SATA ports 1, 2 corresponds to RAID ports 3, 4. I know, go figure! That is one reason why you should enable EVERYTHING before you load Windows, then once the system is up and running fine, then you can fine tune it.Vader said:I've done everything on the list except I only had SATA Ports 1 and 2 RAID enabled...the rest disabled. I'll try that when I get home from work. If all else fails..ill flash it to 1003.
