There's something to be said for being from an island that started out as a penal (in this case, penis) colony.
You've been reading your history books again, haven't you?
Thing is, not everybody in Oz is descended from the penal system or penises, though I suspect a penis was partly responsible in this case.....
Anyhow, I think I'll change tack before I go put my foot in it.
As to the ethernet port not working, well there has to be something fundamentally wrong with the copy of Win 7 for it not to be. I've done several legit installs of Win 7 and have never struck and ethernet port not working.... Win 7 has always installed the necessary drivers. If the copy is legit, ring MS with the error info and they will fix it... or alternatively, go get a legit copy if you don't want to return to Vista.
Besides, the ethernet drivers should be on the mobo installation disk... always have been with every mobo I've had.
