I'm looking for documentation about the Virtual Machine Manager that
creates virtual machines in 386 enhanced mode.  Is it really possible
to run a non-Windows application in protected mode?  I've searched diligently
through all the manuals I could find, but located virtually (sorry :-)
nothing about virtual machines.

The thing that made me think it was even a possibility was an obscure 
passage from the July 1990 issue of _Microsoft Systems Journal_, page 12:

"In particular, Windows 3.0 virtual machines include not only the
virtual 8086 environment that the 386 hardware provides, but also an
optional protected-mode portion.  The first virtual machine created--
the System VM--has a protected-mode portion used for running Windows
applications.  Other virtual machines may have only an 8086 (DOS) portion,
but they can just as easily have a protected-mode portion, allowing
other kinds of protected-mode applications to run in 386 enhanced mode."

Has anyone used this feature?  Does it cause any problems?  How do you
harness the beast?

Thanks,
