Then you should have purchased a hardware RAID card. What comes on the
motherboard is in fact software RAID, it just uses a proprietary driver to
do all the work. (Search the net for Fake RAID of FRAID).

If you can't purchase something like a 3ware card, your best bet is to use
the software RAID that comes with Linux. Otherwise you're just asking for a
world of hurt.
