I bet, that this is the BSDish type of "PARITY ERROR!". I use
non-parity RAMs in one bank of my computer and the bios' memory check
dislikes them very much. But i simple switched of the memory check and
BSD comes up without problems but when it attempts to access the
second 4MB range; then the "NMI" messages comes once...
In your case, that message may be the result of a defective RAM chip.
