| ** 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 |
