NMI /N-M-I/ n.
Non-Maskable Interrupt. An IRQ 7 on the
PDP-11 or 680[01234]0; the NMI line on an 80123486. In contrast
with a priority interrupt (which might be ignored, although
that is unlikely), an NMI is never ignored. Except, that
is, on clone boxes, where NMI is often ignored on the
motherboard because flaky hardware can generate many spurious
ones.
