The RAID controller drivers ARE what's required. The SATA ports on the board are run from the RAID controllers. This does not mean that you must have a RAID setup. The controllers will allow for a single SATA drive cofiguration.

Select the correct drivers for your mobo from the ABit website. Make sure that the drivers are specific to the RAID controller on our board. Most likely these driver came on the CD with the mobo, but downloading the latest RAID controller drivers make sense. Your almost done.
