[coreboot] Re: X220 and coreboot?

[Nico Huber]

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
