 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
