Thanks a lot for the replies, guys. Nothing has worked so far. The only ports on the board are controlled by the intel controller. Whatever port the optical drive is in, that it recognizes. The boot manager also doesn't show the drives.
Tried putting the HDD into the SATA II ports...not recognized.
Updated the BIOS from F7 to F9...drives not recognized.
Different SATA cables...not recognized.
I don't understand what's going on.
EDIT: Nevermind. I hit "load defaults" for the new BIOS and restarted and I see my drives...? Well, I'm not exactly sure what happened, but I guess this is closed.
