Installed but now I have the following error:
boot0: GPT
boot0: testing
boot0: testing
boot0: done
boot1: /boot_

Any idea what this is all about?

I pretty much used your setup because I also have a M2N-SLI Deluxe Amd motherboard.

Okay that problem has been solved. It was something as simple as making sure my firewire was turned on in bios. My current problem is when it boots up the screen goes blue then black? Are you guys experiencing this problem and how did you fix it for the M2N-SLI Deluxe motherboard?

Sorry for the delay, I was in Mexico for vacation. As to your issue, it _may_ have something to do with a hardware compatibility issue... try removing all non essential hardware and (Im sorry to say), start over. Non essential means everything but KB and mouse... additional drives, you name it. Once its installed and working nicely, then you can slowly add back in your additional hardware (one at a time!) and see whats killing it.

Good luck!

Edit: Make sure your video cable is plugged in to the right port - I had black monitor issue, when I didnt realize my monitor was plugged into the second port on the card. Hope this helps.
