If you have a MOBO with 2 RAID controllers installed you might experience problems during the installation of Windows Vista or Windows 7. In my case both Windows Vista and 7 RC weren’t able to load the installation wizard.
The solution is to turn off one of the RAID controllers in the BIOS. It won’t help if you just remove the connections to the hard drives connected to one of the controllers!
I didn’t had any problems with Linux (Archlinux) so far, it just recognizes the hard drives as expected.🙂
