The ROM is soldered on the logic board in a 7600 It's on the bottom out of view unless you have pulled the LB. The ROM slot was intended for any ROM updates that might have been implemented. It was never used. Except internally at Apple and some testing labs. The same slot is found empty on many of the other PCI PowerMacs. Kyle H.
