Ya. You aren't just going to be able to run that script. It assumes you have coreboot checked out and cbfstool built as well as SeaBIOS built. Perhaps Kevin can help you with that? Or he could at least post his SeaBIOS image. You could stitch it into your image.bin after reading it with flashrom.

Okay !
I have a friend who has the same C720P than me, he has Fedora installed on it (no more ChromeOS)
If he dump his bios with « sudo flashrom -r path//to/romfile » can I write it to my chip with « sudo flashrom -w path/to/file » ?
That should work, but make sure you use the '-i RW_LEGACY' option on writing so that it only updates the SeaBIOS portion of the SPI.
Hello
Houston, we have a problem !!!
My friend has removed the write protect screw, and now he does NOT have SeaBIOS anymore !!!
At the blank screen if he press CTRL + L he has like me he heards a bip …
:(
Do you have any idea ?
Just so the internets are aware as well. Here's how we recovered it on ChromeOS:
# mkdir /usr/local/test # chromeos-firmwareupdate --sb_extract /usr/local/test/ # flashrom -w /usr/local/test/bios.bin -i RW_LEGACY
That should restore the contents of that section of the flash.
