I bumped into that as well.  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 :-).

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.
