I have to say you guys have done an amazing amount while I was away, I
have yet to catch up all with the postings. Maybe I should go away
again. :-)

Yup, A20 couldn't be unset while running above 1M or the code would get
gated out of existence. This is in the path that jumps to real mode
images i.e. NBI. So I temporarily disabled the call but it remains to be
fixed.  I like Michael's solution of using an even megabyte.

That too, yes.
