Tyan Barebone B5350G20S4H 1HE 7320 raid

I have bought 3 pieces of :

Tyan Barebone B5350G20S4H 1HE 7320
Intel XEON 2.8Ghz + Hyperthreading 8001H2M
2GB memory
RAID 1+1 (RAID 1 + Hotspare)

And want to install Centos 5.2 on them.

Now i tried several times, and with no luck, because if i use raid 1 the servers gives no operatimg system found.

i looked it up on some forums, and they say its a fake raid.

whats a fake raid anyway if i have a hardware controller in?

Now installed perfectly without using the raid configuration, but want to have raid for 2 disks, and use one as spare.

Can somebody help me on this?
