I intend to merge every Chromebook that Mrchromebox supports, into Libreboot, ready for the Libreboot 25.12 release. Work is still ongoing, and several changes need to happen in lbmk. I started working on it a few weeks ago (today is 14 November 2025 as I push this). Still TODO: * Automatically create lbmk coreboot targets, based on the configs present in MrChromebox git * Re-work git repository management in lbmk, such that a list of upstreams is used, instead of a hardcoded list per configuration; this will allow us to use different remotes across the same project, even where they diverge. This would then allow us to use the MrChromebook repository directly, instead of cherry-picking patches into upstream coreboot * The note above about remotes would also mean that we can use MrChromebox's own edk2 repository directly. All of this would reduce the burden on lbmk.git * Support building edk2 payloads, exactly mirroring the setups used on MrChromebox builds There are some things that need to be checked first, for boards that use MMC-based or eMMC-based storage, for the GRUB and SeaBIOS payloads, also U-Boot, because I will also be using these. As such, this current script shall sit in lbmk master, but it is not yet finished. Signed-off-by: Leah Rowe <leah@libreboot.org>

Libreboot provides libre boot firmware on supported motherboards. It replaces proprietary vendor BIOS/UEFI implementations, by
- Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
- ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
- ... which loads your operating system's boot loader (BSD and Linux-based systems are supported).
Why use Libreboot, and what is coreboot?
A lot of users who use libre operating systems still use proprietary boot firmware, which often contain backdoors and bugs, hampering user freedom and right to repair.
coreboot provides libre boot firmware by initializing the hardware then running a payload. However, coreboot is notoriously difficult to configure and install for most non-technical users, requiring detailed technical knowledge of hardware.
Libreboot solves this by being a coreboot distribution (in the same way that Alpine Linux is a Linux distribution). It provides a fully automated build system that downloads and compiles pre-configured ROM images for supported motherboards, so end-users could easily fetch images to flash onto their devices.
Libreboot also produces documentation aimed at non-technical users and excellent user support via IRC.

You can check bugs listed on the bug tracker.
You may use Codeberg pull requests to send patches with bug fixes or other improvements. This repository hosts the code for the main build system. The website lives in a separate repository.
Development is also done on the IRC channel.
