To add a little bit to the confusion:

I ran a complete disassembly of the ROMs and NOWHERE in the ROMs
there exists the hard address 4F6 = _shell_p. This means that the
ROMs don't dictate its use and any information about that use must come
either from DRI ( the makers ) or Atari. The other possibility is that 
people start allocating the allegedly unused spot by themselves like
Konrad Hahn has done apparently.
Clearly this location was NOT meant for the way gemboot uses it as AES
uses no variables in that range and it sits between a couple of GemDos
variables. Therefore I believe that the use suggested by Allan Pratt is
the correct use, and that gemboot should look for another location.
Anyway I think that Atari should now tell us which address to use for
the gemboot trick of passing resource directory information and which
one for the communication between a shell program and its child processes.
