Seems the CUDA and PMU switch are one and the same. I've tried the DIMMs one at a time, in each different slot and combination - they all check out but anything in slot 4 provokes a complete freeze. I've also done a sustem software 'archive and install' - no effect. I found a G4 'Apple Hardware Test' CD and tried that - it won't even run - boots into open firmware with the error message: Invalid memory access at %SRR0: 0661054c %SRR1: 0003030
Unless someone has a better idea, it seems I've acquired a paperweight. On May 27, 9:48 pm, John Carmonne <[email protected]> wrote: > Just to be sure look near the battery?
