At least BSD and DOS both expect to be called with SI pointing to their
entry in the partition table....doesn't seem to matter where in memory you
leave the table image, so long as the SBR code can see it.  If you do this,
you don't actually need to leave the partition table in it's usual place in
the MBR -- everything will boot ok, but it is still true that fdisk and such
will not like you very much.
