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
