Other posters have said the ASRock BIOS is special. Based on my experience this must be true. I have been unable to get this MB to support RAID. I have finally given up. What I did find was that I could get the drives to appear as independent drives. I installed them as 2 drives. I plan on using rsync to keep them identical. The only way I could do this was to use the "nodmraid" kernel option when I booted to do the installation. I tried contacting ASRock and found their support was useless. They only recommended using the chip manufacturer's driver (something I had already tried). I replied that it didn't work and they stopped communicating. I will not use any more ASRock products!
