> Kevin, we tried out a Supermicro server which had ICH7R motherboard and RAID was recognized fine. FreeBSD recognized all the drives as stand alone plus the "ar0" onboard controller.

Thanks! This is what I had suspected, but it's good to have
Since the RAID is really software and not hardware, it might work as
well to just use gmirror and not worry about the on-board RAID.
