I suggest you read the first page of this thread, if you follow the instructions it does work. If it doesn't it's because you have deviated from the path.

I have used it to install on the V1 and V2 version of this motherboard. The onboard graphics cards will actually work, though only at 1280x1024 or 1024x800. Can't remember which one, but you will see a Mac desktop. Only then would I try and use your graphics card. No idea if your card will work, as never used it. I stuck to Asus 9400 and 9600 and they work out the box which is nice.
