+** 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
