Libreboot is a free boot fimware implementation, to replace the non-free BIOS/UEFI firmware found on most systems. It initializes the hardware and starts a bootloader for your operating system.

License can be found in COPYING and through parts of the source tree.

Libreboot is a free BIOS or UEFI replacement (free as in freedom); libre boot
firmware that initializes the hardware and starts a bootloader for your
operating system. It's also an open source BIOS, but open source fails to
promote freedom; please call libreboot free software.

Why use libreboot?

Many people use non-free boot firmware, even if they use GNU+Linux. Non-free
BIOS/UEFI firmware often contains backdoors, can be slow and have severe bugs,
where you are left helpless at the mercy of the developers; you have no freedom
over your computing. By contrast, libreboot is building a world where
everyone can use, study, adapt and share software, with true control and
ownership over their technology. In other words, you should use Libreboot for
your freedom's sake!

Libreboot is faster, more secure and more reliable than most non-free firmware,
and can provide many advanced features (such as encrypted /boot/, GPG signature
checking before booting your kernel, ability to load an OS from the flash chip,
and more).

Libreboot's main upstream providers are coreboot (which we deblob, for hardware
initialization), depthcharge (bootloader, and default libreboot payload on ARM),
and GRUB (bootloader, and default libreboot payload on x86). We also
integrate flashrom (for installing libreboot), and several of our own utilities,
scripts and configuration files. All of this is integrated into a single,
coherent package that is easy to use. We add our own patches to the various
upstreams used, and where feasible try to merge upstream as much as possible.

Libreboot provides a fully automated build system and installation process, with
documentation written for non-technical users, in an attempt to make the
software as easy to use as possible. ROM images are provided, along with
utilities, all built from the publicly distributed source code.
