Ok so in my 3.1 I have the stock 2600 in lane 2, and then an EVGA 670 in the first lane. I need to re install Lion clean and then windows. A full system wipe and fresh install... only issue is I'm not getting an EFi screen when booting with the 2600? As far as I'm aware, and if past experience (memory) doesnt fail me...it doesnt matter what lane the 2600 is in right? ---------- So I'm now installing Lion from within the OS....but I'm worried I still won't have an EFI...its downloading additional content at the moment so hav got about 30 mins before it restarts!
