I'm running an AT&T PC 6300PLUS with a 2 Mbyte EEMS board.  The
board is configured as 100% extended memory (not expanded memory).
This means that it is only accessible in the protected mode of the
80286, which is our normal operating mode (we run UNIX and MS-DOS
under AT&T's Simul-Task).

Memory errors (NMI) have started to turn up once or twice a week. 
The EEMS board is socketed, and it should be easy to replace the
defective memory chip, but how does one find it?  The customer
diagnostics and the system diagnostics provided with this machine do
not test the EEMS board.  The power-on-self-test does, but it's hard
to let it run continuously for a day or so, as might be necessary to
find the bad chip.

Does anyone know of a diagnostic for testing extended memory?
