But on most of them : (though not all) the pin on ISA works. Some high-end machines : like Unisys or Compaq have an NMI button on the box (sometimes : under the cover). IOCHK* isn't on the PCI bus at all. You have to do weird things for it to generate an NMI that I've never quite worked out. I sure wish I could get the pcccard bus (and/or cardbus) to genereate NMIs for laptop hacking at times.
