Use QEMM, loading all drivers high.  Then load the vidram driver high,
and activate it, to enable the A000 segment for dos use.  You give up
the use of EGA/VGA graphics doing this, but with DOS 4.01, everything
loaded high, and vidram on, I get over 640k available memory.  (Useful
if you want to be able to run the DOS version of COMPRESS using 16 bit
compression.)
