* HISTORY
|

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