By the way, can someone explain the difference between a fluke signature and a checksum? Sometimes my fluke reports a bad rom signature, but that doesn't necessarily mean the rom is bad does it?
Matt
No. But it does mean that EITHER the rom, or the circuitry going to or from the rom is bad. Pop the rom out, dump the rom, then use fluke IDE to calculate the signature of that rom dump and make sure it's what you were expecting. Then if it wasn't then the rom is bad, else start looking at address and data buffers and chip selects and the like.
