When you install QEMM, your machine then runs in V86 mode from that point on.
Ie.  You are already in "Virtual 8086 Mode"!

QEMM permits your EXTended memory to be used as either EXTended or EXPanded
memory, or any combination of both, on the fly.  To do this, it has to lie
a little, claiming that you have 1.7M of EXPanded memory *and* 1.2M (?)
of EXTended memory available at the same time.  You really only have about
1.2M of extra memory.  The 1.7M comes from the EMS 4.0 spec, which allows the
lower 640K to also be used as EMS.

Here is the problem.. someone goofed in the Desqview Setup.  Go back into
the Desqview Setup program and find the "Common Memory" entry.. change it
to something MUCH smaller, like 20K or so.  The name is somewhat misleading,
"common memory" is used by Desqview Programs for odds and ends (I dunno what),
and each window needs a couple of K of it, so 20K is plenty.  Doing this will
free up piles of XMS/EMS for more general purpose use.  Pretty silly, actually,
I think QEMM oughta pool the "Common memory" on demand from the same pot of
XMS/EMS, but it doesn't.

<The manual mentions Virtual 8086 Mode in passing at the beginning and
<glosses over it for the rest of the manual.  How do I access it?

Put QEMM386.SYS into your config.sys, and bingo.. there you have it,
whether or not you actually run Desqview afterwards.

<By the way, please respond in email.  I don't actually read

And this machine can't reliably send email, so too bad.
