last addition:

IMHO there is a good chance that XMS memory is broken; possibly because the BIOS reports free memory in a way that HIMEM/JEMM386X misinterprets.

at least this would be cool to know.

now it would be cool to have a memory test (at least a minimal test) to test XMS memory integrity on this machine.

early HIMEM versions had an integrated test

   HIMEM /T

that would test this integrity by filling all memory with a known pattern, then checking for this pattern. unfortunately, this ability was lost when assembly programmers took over
