Wolf,

I went through a similar exercise last night.  When I ran DOS 5.0 with QEMM
and 4DOS using the UMB switch, I had 635K at the DOS prompt, but only 468K
available for DESQview tasks.  Taking the UMB switch out resulted in only
594K for DOS, but now a whopping 577K for DESQview tasks.  I have since done
away with the switch.
