If you use that brain-damaged emm386.sys, you must be sure not to use
the `noems' option.
This message about V86 is some sort of misleading, as go32 is very well
able to run from V86 mode, as long as the V86-manager supports VCPI.
emm386 does this, when ems is enabled. QEMM dynamically converts XMS to
EMS, so you won't run into trouble with it (there is a noems switch 
for QEMM, too, but there's probably no reason to use it...).
