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...). - Thomas greve AT rs1 DOT thch DOT uni-bonn DOT de unt145 AT dbnrhrz1
