It's all done. Whew. I have two Mac Pro's to do. The other CPU hasn't arrived yet. The next one is a Nehalem 4,1 quad 2.66 ghz. I have a W3090 that should arrive in the next day or two. Now I know how to do it I'm looking forward to it. That'll bring it also up to 5,1 after firmware update and 3.46.
