10 | ** Created 09/29/92 by Greg Harp | |
11 | ** | |
12 | ** 5/2/94 Roman Hodek: | |
13 | ** Added bi_atari part of the machine dependent union bi_un; for now it | |
14 | ** contains just a model field to distinguish between TT and Falcon. | |
15 | ** 26/7/96 Roman Zippel: | |
16 | ** Renamed to setup.h; added some useful macros to allow gcc some | |
17 | ** optimizations if possible. | |
18 | ** 5/10/96 Geert Uytterhoeven: | |
19 | ** Redesign of the boot information structure; renamed to bootinfo.h again | |
20 | ** 27/11/96 Geert Uytterhoeven: | |
21 | ** Backwards compatibility with bootinfo interface version 1.0 | |
