GigaByte MB, WD Black SATA HD, and VISTA (Help)

Posted this in HDD thread as well, but thought this might be better place.

GIGABYTE GA-MA790XT-UD4P AM3 DDR3 AMD 790X ATX AMD Motherboard


Western Digital Caviar Black WD6401AALS 640GB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Hard Drive



I'm trying to install vista 64bit on the above mother board.I've plugged the SATA HDD into the AMD SB750 South Bridge SATA2_0 port (also tried SATA2_1). I get to the point in the Vista install that asks "Where do you want to install Vista?/ Load Drivers" ). I have only one SATA HDD and am not trying to set up a RAID.

When I selected AHCI as the SATA type, I got the option of 2 drivers (If IDE is selected as the SATA type, i get no compatible drivers listed - if i uncheck i can see them as I'm using the GigaByte Driver CD sent with the mobo). Installing either or both (multiple times getting to this point in the install), the HDD will still not show up in the vista install.

TO NOTE: the SATA drive is also not showing up in the initial startup diagnostic or the BIOS, so I think I need to get that resolved before the install even has a chance.

I've tried reconfiguring the BIOS settings under Integrated Periperals. I have the GIGABYTE SATA2 SATA controller disabled (have the SATA drive plugged into AMD SB750 South Bridge SATA2_0 port), and have enable the OnChip SATA Controller. I've tried Native IDE and AHCI as the OnChip SATA type.

Not sure if it's part of the issue, but the DVD optical drive is IDE and configured as Master. I haven't changed the jumper settings on the SATA HDD, so it might still aslo be set to master?

I feel the issue is in my BIOS settings, but I'm not sure what I should the proper settings should be to get it to work.
