But I would like to say that the cp tbug par fault is somewhat of misnomer, since it is, according to a photocopy of the fiche listings (provided by DEC on request), also indicative of cache parity errors and (non-existent) memory timeouts. I have seen software generate this fault (due to bad memory references), and suggest that you check the machine check summary register (mcsr) to determine if bit 3 is on. If so, you've got non-existent memory, not a parity fault, which could be a hardware fault, rumored to be caused by a vendor's chips (I don't (yet) know who) failing spec. /Jskud
