Ok, that's good.  Nothing needs to get passed from partition boot program and
the MS-DOS boot program then (So why is information passed between these
programs? Who knows...  Altough, I guess having the boot table already loaded
into memory is good since then you don't have to reread it) I guess I would
have noticed this if the active DOS partition on my hard disk wasn't first.  

On DOS 4.0, 4 bytes are reserved for this variable so it extends properly.
