It's always better to have RAID, especially if you run XEN since it
will help with IO load.

I would simply disable the RAID setup in the BIOS and then configure a
mdraid in Linux. By the sounds of it you have what's called "fakeraid"
and will probably have more trouble trying to get Linux to see the
drives, than trying to figure out how to setup software RAID on Linux

Just google "setup software RAID on CentOS", or "setup software raid
on Debian" or whichever Linux you plan on using
