  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
