As far as I can tell, there are no drivers needed for SATA if you have Windows already installed and have a sufficiently recent bios (1.30 or later).
If you are installing Windows fresh to the SATA, you may need the floppy version of the drivers which are available on the
ASRock website.
All that is required for the addition of the SATA disk to an already running system is to ensure the correct setting is selected in the bios setup>SATA operation mode.
This board only runs at 1.5 Mb/s for SATA and the disks are hot swappable.
