# Unofficial disassembly of the official OpenBoot PROMs obtained with:
|
| 2 |
|
|
|
| 3 |
|
|
# Step 1: from binary to SPARC ELF:
|
| 4 |
|
|
sparc64-linux-objcopy -Ibinary -Oelf64-sparc ../1c1t_obp_prom.bin 1c1t_obp_prom.elf
|
| 5 |
|
|
sparc64-linux-objcopy -Ibinary -Oelf64-sparc ../1c1t_prom.bin 1c1t_prom.elf
|
| 6 |
|
|
|
| 7 |
|
|
# Step 2: from SPARC ELF to disassembly
|
| 8 |
|
|
sparc64-linux-objdump -D -m sparc:v9 1c1t_obp_prom.elf > 1c1t_obp_prom.dis
|
| 9 |
|
|
sparc64-linux-objdump -D -m sparc:v9 1c1t_prom.elf > 1c1t_prom.dis
|
| 10 |
|
|
|
| 11 |
|
|
# Step 3: hand replace 1c1t_obp_prom with 1c1t_prom in the first of the two so that you can then easily diff them:
|
| 12 |
|
|
|
| 13 |
|
|
$ diff 1c1t_obp_prom.dis.bis 1c1t_prom.dis
|
| 14 |

|
|
> f84bc: f1 00 00 00 ld [ %g0 ], %f24
|
| 16 |
