Bear with me, I don't know much about bios stuff or anything about SATA drives I just built a system with the following: AMD Athlon 64 3000+ Asus A8V deluxe mobo 2 gigs of Kingston DDR400 Geforce 6600GT and a SATA Seagate hard drive It posts, no error beeps or anything, but says I don't have a hard drive. I get the message Bios not installed. I can get into the Bios and the primary IDE is not detected (obviously...its not IDE) and the secondary IDE is my DVD drive that works fine. I thought it wasn't seeing my hard drive but I started pushing buttons (go me!) and found some SATA RAID bios that lists my drive and its size. I dont know anything about SATA or RAID stuff. I know that on my motherboard there are two sata plugs and two sata raid plugs. The drive is connected in the Sata 1 normal plug...not the raid ones. (I dont know what a RAID is...) Any...wild guesses? I'm thinking theres some simple setting in the bios I'm not seeing but I cant seem to figure it out.
