| 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 |
