I need help again!  I am using an old IBM-PC, commonly referred to as
the PC-1 with new bios chip and a fully populated AST 6PACK +.  Ever
so often, the system just hangs up with the message
	PARITY CHECK 2
on the left top corner of the screen. It seems to occur at
random intervals, about once every half hour of use.  I have
tried all the IBM diagnostics and consulted local support.
To no avail.  The only thing I can think of, related to something
I read in the Dr. DOBBS JOURNAL (Nov. Issue) about faulty
DMA chips in some of the machines (also present in AT&T 6300 )
Any help in resolving this would be appreciated.
				Thanks
				Rajiv
