"MAY" just work is what worries me. BIOS writers have been eliminating
old features to make room in BIOS chips for new things, like USB. Also
note that XMGR's current scan-memory logic exactly fits in the space for
a table of 48 XMS "handles", leaving no wasted initialization code. If
anything else is added, I need a new "scheme" for where to locate XMGR's
initialization routines, so they disappear completely after init.

Give me a bit more time to "think about" this item. I enjoy a "Mission
IMPOSSIBLE" task, as were XMGR/UIDE, and some DO say I am a "Hoodoo Man"
who works miracles, i.e. it probably can be done!
