Learn how to build Zerocat’s Coreboot ROM for a small but interesting set of ThinkPad laptops:

  • X230, T430, T430s
  • X220, T420, T520,
  • X200, X200t, T400,
  • X60, X60t, T60, T60 with ATI_Mobility_Radeon_X1300

See Toolchain, List of Files and Related Pages to get started.
File CHANGES tracks most recent development.
To get an overview of used, external projects and their versions, see the setup-toolbox.sh file reference.

The README might give you some valuable, but probably outdated information. Same with GRUB How-To.

The Build How-Tos are quite useful, but they do not yet take into account how to increase the BIOS region if the IME region has been cleaned with ME_Cleaner. However, the toolchain scripts already know how to do it, if applicable! Check out How To Modify The Intel Flash Descriptor1.

Once you have liberated your laptop, protect it! See Sleeves to see how to make a sleeve for it.
