  10** Created 09/29/92 by Greg Harp
  11**
  12** 5/2/94 Roman Hodek:
  13**   Added bi_atari part of the machine dependent union bi_un; for now it
  14**   contains just a model field to distinguish between TT and Falcon.
  15** 26/7/96 Roman Zippel:
  16**   Renamed to setup.h; added some useful macros to allow gcc some
  17**   optimizations if possible.
  18** 5/10/96 Geert Uytterhoeven:
  19**   Redesign of the boot information structure; moved boot information
  20**   structure to bootinfo.h
