you are very kind - seriously thank you. Okay, maybe i am not the search maestro that you are - I was in the moment - brand new Mac Pro and first search yielded bogus random links. Your first link is a joke but number 2 helps a bit. Apple doesn't want users doing these installs but I live and Maine and had to chance it. It was a bit of a pain to seat the antenna wires and no link discussed that. I may have voided my warranty - OH MY GOD!! I have Apple Care and that will be nice. Again thanks. I know there are people here that make careers out of bugging people to use the SEARCH tool more effectively.............i do it too!
