Re:   Getting P2DOS running on H89

     The basic problem I had with P2DOS stems from an error in the
support utilities provided in the distribution.  Somewhere during the
steps to relocate the .REL file the resulting .COM file grows to be
larger than 0E00h bytes.  I was zapping zeroes on top of the BIOS
when trying to overlay the BDOS.  At any rate,  LOAD/SAVE 14 resolves
the problem by shrinking the .COM file to its correct size.

     There is one other problem I encountered that is specific to
the H89's BIOS implementation.  P2DOS, as distributed, uses 0040h
and following for its file search path table.  0040ff has been
reserved by DRI for BIOS, not BDOS usage.  The Heath BIOS uses
that area for its logical/physical drive map.  So, either disable
the feature in P2DOS, or move it somewhere else.  (There is room
in P2DOS itself for it.  When I get some time, I'm going to try
it there).

     At this time I have it running just fine with the path
feature disabled.  I'm using it with ZCPR (as in ZCPR1) so the
path feature is only partly missing.
