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