Indeed there are.  I have previously seen problems with FreeDOS that
have turned out to be FreeDOS problems more often so than MEMDISK problems.

My initial guess would be that FreeDOS -- in particular, FDXMS286.SYS --
gets unhappy about the way MEMDISK handles INT 15h AH=87h, the so-called
"high memory mover" API.  The "286" part of that worries me, since INT
15h AH=87h is a bit different between 286 and 386.
