# Skulls - not quite Heads [![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/5326/badge)](https://bestpractices.coreinfrastructure.org/projects/5326)

pre-built [coreboot](https://www.coreboot.org/) images with an easy

installation process

![seabios_bootmenu](x230/front.jpg)

Skulls makes it easy to install an _unlocked_, _up-to-date_ and _easy to use_

coreboot-based BIOS on your laptop.

* _unlocked_: software update after first-time flashing / no restrictions for connected hardware

* _easy to use_: SeaBIOS - simply a boot menu, compatible with Windows and Linux

* _up to date_: Frequently a new image with the latest versions of all components

## Supported Laptops

* [Lenovo Thinkpad X230](x230/README.md)

* [Lenovo Thinkpad X230T](x230t/README.md)

* [Lenovo Thinkpad T430](t430/README.md)

* [Lenovo Thinkpad T530](t530/README.md)

* [Lenovo Thinkpad W530](w530/README.md)

* [Lenovo Thinkpad T440p](t440p/README.md)

## 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 new coreboot development that affects us, or

* We change the config

## How we build

* Everything necessary to [build coreboot](https://www.coreboot.org/Build_HOWTO) is included here

* When doing a release, we always try to upload to coreboot's [board status project](https://www.coreboot.org/Supported_Motherboards)

* If we add out-of-tree patches, we always [post them for review](http://review.coreboot.org/) upstream

* The scripts to build reproducibly are based on

[these](https://github.com/Thrilleratplay/coreboot-builder-scripts)

scripts that use the

[coreboot-sdk](https://hub.docker.com/r/coreboot/coreboot-sdk/).

## Alternatives

We aim to be the easiest possible coreboot distribution - both

to install and to use. And since our flash image is unlocked to enable

software updates, it's easy to move to alternative systems from it:

* [Heads](http://osresearch.net/) - a 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](https://libreboot.org/) - a coreboot distribution with pre-built

image releases. Supports a lot of devices these days, including most of

what Skulls supports.
