| 29 | * HISTORY: | |
| 30 | * 16-Mar-88 John Seamons (jks) at NeXT | |
| 31 | * Cleaned up to support standard disk label definitions. | |
| 32 | * | |
| 33 | * 24-Feb-88 Mike DeMoney (mike) at NeXT | |
| 34 | * Added d_boot0_blkno to indicate logical block number | |
| 35 | * of "block 0" boot. This blkno is in d_secsize sectors. | |
| 36 | * Added d_bootfile to indicate the default operating system | |
| 37 | * image to be booted by the blk 0 boot. | |
| 38 | * Changed d_name and d_type to be char arrays rather than ptrs | |
| 39 | * so they are part of label. This limits length of info in | |
| 40 | * /etc/disktab, sorry. | |
