- ** 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
