About the libreboot project

Libreboot is a coreboot distribution (distro) with proprietary software removed, intended to be a free (libre) 'BIOS' replacement for your computer. The project is aimed at users, attempting to make coreboot as easy to use as possible. Read the full Free Software definition.

Libreboot also has many practical advantages over proprietary boot firmware, such as faster boot speeds and better security. You can install GNU/Linux with encrypted /boot/, verify GPG signatures on your kernel, run a full operating system directly from the flash chip (planned for a future release), and more.

The libreboot project has three main goals:

Libreboot is a coreboot distribution, not a coreboot fork

Libreboot is not a fork of coreboot. Every so often, the project re-based on the latest version of coreboot, with the number of custom patches in use minimized.

All new coreboot development should be done in coreboot (upstream), not libreboot! Libreboot is about deblobbing and packaging coreboot in a user-friendly way, where most work is already done for the user.

For example, if you wanted to add a new board to libreboot, you should add it to coreboot first. Libreboot will automatically receive your code at a later date, when it updates itself.

The deblobbed coreboot tree used in libreboot is referred to as coreboot-libre, to distinguish it as a component of libreboot.

Libreboot is a 'stable' version of coreboot
