Before, the T440p blob scripts would look for Coreboot using the find
command. Now, we require the user to specify the path to Coreboot in the
COREBOOT_DIR environment variable. Also, add an output directory
argument to each script.
These changes will make it easier to integrate with the Heads build
system and CI.
- I extracted the gbe.bin blob from my T440p's original ROM using the
blobs/t440p/extract script.
- Using a hex editor, I corrected the sign bit in part 0 that I found
was malformed in my analysis:
https://github.com/osresearch/heads/pull/1282#issuecomment-1400634600.
- After correcting the sign bit, nvmutil showed that both parts of my
gbe.bin blob had valid checksums.
- Finally, I used nvmutil to set the MAC address to 00🇩🇪ad:c0:ff:ee.
