Hello folks I've pulled the dual processors from my recently purchased G5 as they were loose and I wanted to clean the system prior to rebuild....stupid question 101 is there a Master/slave setup or can they just go back in either socket? If there is an order how do I tell? There appears to be small round hand written stickers saying A&B in very bad writing is this a clue? Or do the serial numbers give me a clue? Many thanks N.
