Biostar K8M800 AM2 motherboard doesn't detect SATA HDD

I have an old Biostar K8M800 AM2 motherboard, and I can't seem to get it to detect a SATA hard drive.

It boots just fine from an IDE drive, but the BIOS simply does not see the SATA Seagate hard drive that I'm trying to get it to boot from. (I have verified the drive is fine using another computer)

I downloaded the PDF manual to see if there is a jumper I have to set on the board to enable the SATA ports or something, but I wasn't able to find anything.

I also ran across this unsolved thread from 2005, where the OP has the same issue.

Any ideas as to why the BIOS doesn't see it?

Solution 1:

Make sure that the SATA controller is enabled (and not RAID).
Note that RAID mode is the default configuration in that BIOS.

from ftp://ftp.biostar-usa.com/manuals/K8M800MAM2/K8M800%20Micro%20AM2bios.pdf

OnChip SATA
This option allows you to enable the onchip Serial ATA.
The Choices: Enabled (default), Disabled.

BTW that mobo only has SATA 1.0 ports.
