31 |
* |
32 |
* This program takes a textfile containing a DECstation |
33 |
* PROM memory dump of the following format: |
34 |
* |
35 |
* bfc00000: 0x12345678 |
36 |
* bfc00004: 0x9a8a8a7f |
37 |
* and so on |
38 |
* |
39 |
* and turns it into a binary image (32-bit little-endian words -> bytes), |
40 |
* |
41 |
* 0x78 0x56 0x34 0x12 0x7f 0x8a ... |
42 |
* |
43 |
* To produce such a dump, hook up a serial terminal capable of capturing |
44 |
* data to a file, and enter the commands |
45 |
* |
46 |
* setenv more 0 |
47 |
* e -w 0xbfc00000:0xbfffffff |
48 |
* |
49 |
* at the DECstation's PROM prompt. |
