I have the same motherboard and have had numerous problems setting up windows with this. I happen to be using two SATA WD Raptors in raid 0, and in order for windows to install on them, you need the mass storage drivers for the sata and raid controllers. Since you are not installing on raid, you can probably get away without using the raid controller, but you may want to dig up a set of the SATA controller drivers and give those to XP when it asks for mass storage drivers in the beginning of the install process.
Also, if you have any IDE HDD's installed, you way want to remove them for the duration of the install process (cd/dvd drives are OK). Sometimes XP gets confused when you mix and match on this motherboard. Once XP is installed, you can plug the other drives in and it should work fine.
