I recently purchased a 20MHz 286/NEAT motherboard which advertized
LIM/EMS 4.0 compatability.  I have 2MB in memory bank 0 (no
interleaving... sigh).  With it came the Expanded Memory Manager device
driver, NEATEMM.SYS, made by Chips and Technology, and a small doc file.

The doc file seems to indicate that no parameters are necessary to the
driver and that it reads the default parameters that were established by
extended setup from the NEAT hardware.  It also says that if the default
parameters are "wrong", the driver will detect this and issue the
message "The EMS setup has been incorrectly specified.  No EMS is available."

I've tried many different variations of the extended setup, but I always
get the undescriptive error message above.  I tried all "EMS Base Memory
Addr" from C400, C800, ..., F000.  I also tried all "EMS Base I/O Addr"
from 208/209, 218/219, ..., 2E8/2E9.  I have not tried all combinations
of the two.

Is it true that the device driver does not need any parameters?

Does anyone know what the constraints are for getting a proper EMS setup?

My extended setup is as follows:

	BIOS Rom:			Enabled
	Video Rom:			Enabled
	Shadow 16K at C4000:		Disabled
	Shadow 16K at C8000:		Disabled
	Shadow 16K at CC000:		Disabled
	Shadow 16K at D0000:		Disabled
	Shadow 16K at D4000:		Disabled
	Shadow 16K at D8000:		Disabled
	Shadow 16K at DC000:		Disabled
	Shadow 16K at E0000:		Disabled
	Shadow 16K at E4000:		Disabled
	Shadow 16K at E8000:		Disabled
	Shadow 16K at EC000:		Disabled
	Memory Wait States:		0 wait states
	640K-1024K Relocation:		Enabled
	EMS Base Memory Addr:		DC00
	EMS Base I/O Addr:		208h/209h
	EMS Page 0 Register Extension:	1M to 2M
	EMS Page 1 Register Extension:	1M to 2M
	EMS Page 2 Register Extension:	1M to 2M
	EMS Page 3 Register Extension:	1M to 2M
	EMS Memory Size:		2.0M
	EMS Wait States:		1 wait state
	EMS Memory:			Enabled

Also, how can I find out what the above parameters do?

Thank you for any help you can offer.
