I just bought a barebone computer with the p4c800-e-dx and a P4 3.2 GHZ FSB 800. I put a used/working hard drive in, and when i boot up, it says "No Hard Drive Attached to Fast Track Controller. The BIOS is not installed". Ok, the bios is installed because i can go into it, so the only other thing that means to me is that the BIOS must be installed onto the hard drive or something. If it helps its a Samsung 40 gb hard drive. If anyone can help that would be great, Thanks Cougar989
