I too have had a lot of problems with this motherboard trying to set up RAID 0 on XP. The DOS drivers would not load in the standard way (using floppy). In order to get the installation to first see the stripe I had to slipstream the DOS driver using nlite (I don't know if there is a version of nlite for vista because I don't use vista). However, after the installation completes and goes to the 2nd reboot it blue screens even after slipstreaming the windows driver into the installation. I have been told that problems with RAID can be due to errors on the disks. I was using 2 80 Gb seagates previously striped on another gigabyte board, so I not sure how accurate this is, but upon testing them they did indeed both fail some seatools tests (downloadable from seagate). These have now been replaced by seagate and are error free, yet still the installation fails. The next suggestion has been that there is a fault on the chipset, which I'm about to get tested. I have managed to get a RAID 0 installation to boot using windows backup from an IDE disk. However, something gets skrewed in the reg because when you login it just logs straight out again.
