do you need a ready-to-flash coreboot ROM? Did I understand correctly?

Well. Sorry, if this is very stupid question, but trying to follow
instructions at:  https://thiccpad.blogspot.com/#

Step: *ifdtool -x original.bin # original.bin** is the firmware you read
from the motherboard*

*and I don't have this original.bin as it readed from bios chip of
motherboard?*

*Is it needed or not?*

Ah, I see.

I guess, you could flash coreboot on your device, but I REALLY would
advice to make a backup of your existing BIOS first, in case anything
goes wrong

Hi Eero,

to switch from vendor firmware to coreboot, on an X220, you need either an external flash programmer or a slight hardware modification (connect a certain pin to disable flash protections). The latter requires a very fragile software procedure. Otherwise, you won't be able to write to the flash chip.

Extracting parts of the backup is only needed if you want to alter the ME firmware, but not required for coreboot.

Hope that helps,
Nico
