skulls - coreboot your device the easy way

pre-built coreboot image and documentation on how to flash them.

• currently only for the Thinkpad X230.

SeaBIOS is used, to be compatible with Windows and Linux, and to be easy to use: simply a boot menu and a few options to tick.

We want to make it easy to "bootstrap" your laptop to a working, unlocked, up-to-date coreboot-based BIOS.

When do we do a release?

Either when

• There is a new SeaBIOS release,
• There is a new Intel microcode release (for our CPU model),
• There is a coreboot issue that affects us, or
• We change the config

How we build

• Everything necessary to build coreboot (while only the top 4MB are usable of course) is included here
• The task of building coreboot is not too difficult
• When doing a release here, we always try to upload to coreboot's board status project
• If we add out-of-tree patches, we always post them for review upstream

Alternatives

We aim to be the easiest possible coreboot distribution - both to install and to use. And since our images are unlocked to enable easy software updates, it's easy to try alternative systems too:

• Heads - coreboot distribution with pre-built (or reproducibly buildable) flash images (for the X230 and others). Heads includes Linux, with tools to create a trusted boot chain using your GPG key and the TPM.
• libreboot - also a coreboot distribution with pre-built image releases. The X230 is currently not supported (the X200 is) - libreboot images are built from free software only and include the GRUB bootloader.
