	I have a DTK 12MHz '286 motherboard that uses the C&T NEAT chipset.
	The board supports up to 8 MEG of memory that can be extended or
	(supposedly) LIM 4.0 expanded.  When my applications use the expanded
	memory I get an intermittant but regular parity error notification.
	If the memory is configured as extended, it has never failed diagnostic
	diagnostics.  The parity error occurs at zero or one wait state,
	and the memory passes Borland's "emstest" program included with
	QUATTRO pro.   I've never actually seen a data error in my 
	applications, and I can redirect the NMI interrupt to an immediate
	IRET, but that doesn't give me a good feeling.  I really think the
	memory is OK (I've swapped some to no effect), and think it may be
	the driver.  Does anyone else who has a NEAT-based board have this
	problem, or some insight ?
