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 ?
