-** 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; renamed to bootinfo.h again
