The innards of the PAL aren't documented anywhere that I could see and there seems to be quite a lot of logic when the only inputs are the PCI clock and the NMI switch. (Bloated design and undocumented internals - sounds familiar :-). >Pin 42 is #SERR and the other side of it in ground. Does anyone with knowledge of the PCI spec know if just shorting #SERR to ground will work? (Assuming that the BIOS/chipset maps #SERR to NMI). I've used a screwdriver on an ISA slot on several occasions but haven't tried it on a PCI bus yet. -- Peter Jeremy
