How to build an NMI generator board?

I saw some instructions once on how to build
this hardware board when you need to break into
a locked system that does not have an NMI button.
Does anyone know where to find it?

I think I should watch the DVD of ‘Lost In Translation’.

there’s an easy to build NMI Switch PCI board in there. Note however that
there’s no documentation for the AMD 20R4 Pal program, although it should be
pretty easy to figure it out - the 20R4 and the 7406 are there just to make
sure that the PCI spec is obeyed (as far as the NMI signal goes), however,
it’s just as easy to remove those parts out, and you can do it with the
74HC14 alone. One of our QA guys tinkers with hardware, and he wired a few
of those for us. You can do the same on an ISA board, it’s probably almost
the same circuit.

I actually got the equations for the PAL by calling up Microsoft tech
support. However, I can’t find them now, even though it seems like
something that I would have saved. The only odd thing that I recall was
that the SERR# had to be active either exactly 1 clock or maybe more than
one clock.

We did something similar for ISA by using the IOCHCHK signal. We sometimes
even do that by hand by just taking a wire and manually shorting it to
ground. The timing isn’t that key on that signal.

Thanks, I think our PCI guys can figure out what SERR needs to be.
