You need to find out what provides this. A quick google on that board 
suggests that it is supported by the ICH6 south bridge, which is not 
hardware raid, but rather a hardware-assisted software raid with a 
specialized driver (fakeraid). This is contrasted to the normal Metadisk 
RAID which is a pure software raid.

See:

And:
http://linux.die.net/man/8/dmraid

Unfortunately, from here on I can be of little help. I've always 
profaned from those setups. If I'm going to do real hardware RAID, I 
grab a 3Ware Escalade (or similar). If I'm going to do software RAID, I 
use the standard Linux software RAID (and, indeed, this is how I run 
Proxmox. Ssssh. Don't tell anyone), as it is more portable between machines.
