Procedure
-
Disassemble your ThinkPad completely. The BIOS chips are on the inner side of the motherboard (the side the CPU is on), which makes you need to remove the complete casing cage around it to be able to reach them.
-
Setup your Raspberry Pi to run a Linux distro, I used Raspbian from the Raspberry Pi website, the packages listed on the requirements page and install flashrom. In case you Raspbian, you need to download and compile flashrom yourself like it is written on the wiki page of flashrom (linked on the requirements page under Software), but that takes a few minutes at max.
-
Connect the clamp to the RaspberryPi accordingly. It is safe to use the pin layout of bibanon's guide, but the picture shows the small GPIO layout. You can use the same pins on the big layout, when chosing them relative from the left (outer) side only. Check the chip documentation once again before connecting the clamp to make sure you got everything right. For orientation there is a small hole on the top side of the chip that marks the position of pin one. The other positions should also be marked with small numbers on the mainboard itself.
