>that can make it emulate a PC?

I don't have flightsim, so I can't try it, but Window's 386 appears
to emulate a PC in the windowed command.com sessions.  It seems to
be a very good emulation of the CGA hardware.  Several relatively
nasty things I have will run in the window.  Also be warned, the
fact it is an emulation is apparent.  It ain't real fast.  With
four virtual machines running, I got a Norton SI rating of 0.4.
With only one virtual PC running it is about as fast as a ... PC.
Microsoft supposedly has a new version in the works that will pep
things up a bit (hopefully a lot).  In all fairness, windows native
applications run significantly faster than DOS stuff running in a
window.  Interestingly, DOS applications running in an exclusive
window are actually faster than in DOS itself.  For instance, SI
running under DOS gives me 16.9.  When I run it in an exclusive
window, it rates 17.6.  This is prbobalby because windows appears
to copy everything for the virtual machine into extended memory,
including the BIOS (RAM running without the wait states incurred by
the system ROM).
