I have sata slots 1 to 5 filled. At first I had #3 open and it detected an hdd. Then I switched it so #6 was open and now it only sees the sdd.

Has a bunch of other misc boot options but only one drive.

Got the new mobo cuz old one died.

Haven't installed any drivers obviously because i can't boot. Pump also doesn't seem to be running (plugged into cpu fan hesder)

Resolved maybe? I put the windows drive into sata1, it showed up as bootable, booted, got bios, installed new bios, and now it can see all of my drives. No mention of this being a necessity in the manual, however.
