There is a message that comes up that says installation failed with the XP drivers. I had the Vista RC and everything worked just fine, so this is confusing me. I have just reinstalled, because I think I may have messed something up.
Update: I reinstalled the beta, and was able to install the latest XP drivers from HP. This yielded no improvement. On Softpedia I found Vista drivers for the AC-97 (Link Removed - Invalid URL) This yielded a failed installation.
