The rom is a small card similar in concept to a memory dimm. It is very easy to replace. The board revisions have more to do with the onboard video chip. While there are certain combos that came from the factory, any combo will work. >If I understand correctly, the >big problem in G3's is that the Rev. 1 (MoBo or ROM?)
