- ** 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
