|
|
** 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
