FRAM71B

[Dave Frederickson]

Hi Erwin,

I only pointed out a procedural error and offered two techniques for emulating the removal of memory modules. If you follow the rules, as best as we understand them, you should be able to avoid MEMORY LOST.

Just so we don't get confused later, SYSRAM is the 64K of FRAM from 0x00000-0x1FFFF that can be loaded with an alternate O/S or the Diag ROM, replacing SYSROM. The memory you're trying to maximize should be referred to as MAIN RAM.

Speaking of maximizing memory, how are you coming with the questions I suggested you ponder?

To make it easier for you to figure out your memory configuration you might try drawing memory maps or add an "H-Address" column to your configuration table. I notice that none of your logs show H-Addresses. Use MEMBUF to understand where in memory your modules are getting mapped.
