I have to say, I see a lot of posts everywhere saying they couldn't get Vista RC2 to run correctly on Nforce2 platform. I created a silicon array RAID-1 and used the driver provided for XP and was able to install with no issues except audio. Granted, the drivers were all "standard" but I was able to upgrade memory controllers, etc. with the XP nforce drivers. Audio was a pain in the ass though. Install, update, uninstall reboot...
