Dual booting windows and linux with my chipset seems not possible at the moment.....
given up
So only one OS can use the RAID.
Pity really as windows was flying on raid0 - hd benched at a stagering 95MB/s
I've split the RAID up and am now gettin 53MB/s in windows and 60 MB/s in linux grrrrrrrrrrr
Might just let windows have the raid (afterall Windows needs all the fastest hardware it can get just to run reasonably) and stick linux on an IDE
