I just saw your blog post about the BIOS lock bypass you did on your X230, and I was very excited, I just did the same thing on a T430 and T530 a week or two ago! I was planning on making a post of my own about the removal and subsequent coreboot installs for both, but I wanted to send you https://milaq.net/thinkpad-password-removal/ as a list of all the locations you need to short for all Ivy Bridge thinkpads.
