** 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; renamed to bootinfo.h again

** 27/11/96 Geert Uytterhoeven:

**   Backwards compatibility with bootinfo interface version 1.0
