For the past few months, I've been experimenting with hardening thinkpad against attacks and trying to reduce attack surfaces as much as possible. One thing I've been meaning to do for a while is install coreboot + seaBIOS as the T420, t430, and x220, the machines I've been working with, are all supported. I disassembled the test t420 today, removed the motherboard, and located the flash chip. Unfortunately a low-quality soic-8 clip prevented me from being able to flash the bios. Hopefully the new one coming tomorrow will fix that.
