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
