Okay, please clarify this for me, somebody.

Given the current generation clone-boards with hardware 4.0 support
(in particular, the Suntac with SEMS4 as the EMS driver), will Desqview
be able to use expanded memory correctly?  These boards insist that you
FIRST fill up the 640k base memory before turning all of the remaining
memory into (switch-selected) expanded or extended memory.

Right now mine has 1M memory, with 640k base + 384 EMS.  I can't remove
any from the base.  Will Desqview be able to do EMS swapping?  Or,
will it be able to swap into extended memory, if the EMS is disabled?
