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
