Having updated my 775 rig as far as can go, more or less, I'm left with enough stuff to make a "back up" rig. So it's all there, boots into bios screen, set to AHCI (or IDE) but no sign of the hard drive. I've tried two HDDs (both with OS already installed) in port 1 (didn't try different ports yet) but no sign of either. Any thoughts? Thanks in advance.
