Hello Nico,

Thanks for replying.

... "tl;dr Go!" ...

Though, I didn't understand that but I interpret it as a request to go on.

... "AFAICT" ...

I also didn't get that.

Should I use this tutorial, that applies to the ThinkPad X200 where I got a ThinkPad X220, for opening the housing and figuring out what screws to open in order to get access to the chip or is there one for the ThinkPad X220, too (https://libreboot.org/docs/install/x200_external.html)?

tl;dr Go!

If you want to be 100% sure, you should open your ThinkPad and check
that your BIOS flash is indeed in a SOIC-8 package, and that there is
only a single flash chip. In theory it can be different, but so far
people have only encountered a single SOIC-8 chip, AFAICT.

Minor corrections: Pomona is the name of the manufacturer (of the
better clips). You only need 6 wires; /HOLD and /WP pins of the flash
are already properly connected by the mainboard.

Nico
