Depends on the chipset on your board. I'm scanning another support forum now dealing with an Asus setup.

Why do i have to install a RAID-driver to install XP? My drive is on the SATA1?It's because the mobo you chose, only supports RAID on those ports. The VIA 8237 chip doesn't support running the SATA1 & 2 ports in non-RAID mode. EDIT: Hate to say this, but the only mobos I know which can run non-RAID SATA are those using the Intel ICH5 class of chipset, and those are P4 boards, not AMD. I think everybody's hardware can do it, but for some reason nobody's writing software drivers that run this way.

I haven't gone through your board specs, so how much of that applies to you I don't know. The other thing mentioned is making sure your BIOS has the SATA RAID controller turned on. (That'll be under advanced chipset / onboard peripherals or something like that in your BIOS)
EDIT--
going thru the manual. Nice board!
Since it seems to support both SATA/PATA RAID setups, I would think you shouldn't need the RAID driver installed - it's separate from the HD controllers. You do need to make sure your SATA is turned on in the BIOS (Integrated Peripherals).
Make sure your 1st/2nd/3rd Boot Device in Advanced Bios Features are set to CDROM, SATA HD (or whatever they call it), FLOPPY. Turning on the "Boot from other device" might help (you can always turn it off again).
This board also has an F11 "Select First Boot Device" option. This does not change your BIOS, it works only for the current bootup.
