Read this VERY carefully: http://www.planetamd64.com/index.php?showtopic=17812 If it still does not work then give another holler.
ALWAYS install the latest version number. Read the link in my post above. I had the same problems while setting up my friend's DFI Expert SLI setup and I used that guide to give me a helping hand.
