I have an Abit IS7 MOBO, Seagate Barracuda 7200.7 HD. The Bios settings should be similar on most MOBO's. If you have an IDE drive connected, disconnect it until you have Windows installed on your SATA drive. This is to keep the IDE drive from stealing the drive letter C: from your SATA. The 3d party drivers only need to be installed if you are setting up RAID (which apparently you're not). Do the following settings in your BIOS:
ONCHIP IDE DEVICE (hit enter)
IDE BUS Master------Enabled
Onchip IDE 1 & 2----Enabled
All the drive settings-Auto
ONCHIP SERIAL ATA
Onchip Serial ATA mode---IDE
SATA Raid ROM-------------Enabled
Onchip Serial ATA----------Enhanced
IDE 3-------------------------IDE 3 Master
IDE 4-------------------------IDE 4 Master
I built this comp on the 26th, and have been searching for the right way to install SATA until yesterday. That's when I found out my drive WAS running in SATA. I had found posts that said the SATA drive would show in Device Manager as SCSI. That's incorrect, it will show under IDE/ATA ATAPI (Primary).
I hope this works for you. Post back if you have problems, and MAYBE I can help.
