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; moved boot information | ||
20 | ** structure to bootinfo.h | ||
