| 26 | * HISTORY | |
| 27 | * | |
| 28 | * 14 May 1992 ? at NeXT | |
| 29 | * Added correct padding to struct nextvend. This is | |
| 30 | * needed for the i386 due to alignment differences wrt | |
| 31 | * the m68k. Also adjusted the size of the array fields | |
| 32 | * because the NeXT vendor area was overflowing the bootp | |
| 33 | * packet. | |
