Too much software orientation in this group... ;-)

Here's a hardware question.  If I have a RAM board with parity, and get 
a parity error, what should happen?  Should the hardware do a...

	- nonmaskable interrupt?
	- interrupt at lower level?
	- bus error?
	- something else?

I'm curious about how the operating system is currently set up to handle 
this situation, or if it isn't.  Now, to avoid the religious wars about 
crashes and what other brands do, assume for a moment that detection of
corrupt memory is desirable in some applications.

If the answer is in the A-W software technical manuals or either hardware 
manual, it has so far eluded me.
