I have the same mobo and am using the RAID1 feature.  Works fine with no 
drivers.

Here's how to test your RAID, since you don't have any critical data 
yet.... pull the SATA drive cable off one drive (sata0) and see if it 
boots :)  If it boots, then it's working correctly.  Reattach the cable, 
reboot, and let the mirror rebuild and repeat for the other drive.

Having used hardware and software RAID, I am a firm believer is software 
RAID for the following reason:  You can monitor the status of the RAID 
set via the Linux proc filesyste and generate alerts if it ever breaks. 
  With this Abit board, I have no idea if the RAID set is broken or not, 
except to watch BIOS as it reboots.

There is some pretty good support for S.M.A.R.T. in Linux, and you can 
use that to monitor the health of the drives.  Combine that with /proc 
monitoring, and you will have a pretty good monitor for your hard drives.

In business, there are always problems.  It's how they are handled
that makes a difference.  Are you happy with your IT Manager?
