Help needed with ISC 2.2 installation.

Some additional points.  During my first attempt to install ISC 2.2,
I got the following messages at about the same point in the process:

 NOTICE: Unexpected NMI in user mode! (or system mode)

 WARNING: User NMI trap: unable to determine source of NMI.

The messages were repeated over and over.  It was not possible
to shut the system down, since the shutdown command would be interrupted
by another NMI.

Now, an NMI can be caused by one of two things : Parity Error in RAM,
or the IO_CH_CHK signal being asserted by a peripheral card.  I ran
the CHECKIT system test software, which said my RAM was A-OK.
I therefore pulled all but the essential cards (leaving VGA and ESDI only).
Note that CHECKIT tested my RAM as expanded RAM and not extended RAM.

Do any peripheral cards assert IO_CH_CHK?  According to my handbook,
it is supposed to be there to allow peripherals to signal error conditions,
but no examples are given.

Is there any simple way to mask off the NMI interrupt, which will not
be undone by the boot process?
