HIMEM.SYS has got to be the most finicky device driver I've ever seen.
It uses a different strategy to control the A20 line on many different
types of machines, and "guesses" incorrectly on a lot of clones.
How QEMM386 and 386^MAX do it so transparently is beyond me.
Try playing with the /MACHINE:n (n ranges from 1-17 or so) command
line switch (it's documented in the README file) until you find
the right one.
