[comp.sys.zenith.z100] Configuring S-100 RAM

How do you configure S-100 RAM into an MS-DOS HZ100 system ?
I have basically no doc, monitor ROM V2.5 and MS-DOS V2.21,
and two 64kb RAM cards that are set-up to work in a similar
HZ100.

	Thanks, Gern.

	I have a 192K motherboard, and these non-Zenith cards were used
	successfully in another 192K motherboard HZ100, both stuffed to
	192K.  S)ystem in the monitor verifies 192K of contiguous RAM.
	I did not change the switch settings from the other HZ100, so
	presumably the problem lies with my version of the monitor ROM or
	DOS.  I am unsure of both what addresses they belong at and which
	part of the software is responsible for configuring them.  I have
	two 64kb boards.
