Libreboot

Libreboot (briefly known as GNU Libreboot ) is a free software project based on coreboot, aimed at replacing some of the proprietary BIOS firmware contained in some computers, though does require certain vendor code on some platforms as that code may not have been replaced with   libre software. Libreboot is a lightweight system designed to perform tasks necessary to load and run a 32-bit or 64-bit operating system.

Characteristics
Libreboot is established as a distribution of coreboot, but with some proprietary binary blobs removed from coreboot. Libreboot makes coreboot easy to use by automating the build and installation processes.

On some devices, Libreboot developers have reverse engineered the firmware from Intel and created a utility to create a free firmware that meets the specifications from Intel. Hardware support includes but is not limited to the ASUS KGPE-D16, ThinkPad T400, X60 and X200. Libreboot is officially endorsed by the upstream coreboot project.

History
The Libreboot project was started in December 2013 as a distribution of coreboot, which excludes non-free binary blobs. Coreboot began as LinuxBIOS in 1999 at Los Alamos National Labs (LANL), and was renamed "coreboot" in 2008.

Libreboot has been endorsed by the Free Software Foundation, and was an official part of the GNU Project since May 2016. In January 2017, the project's maintainer Leah Rowe pulled Libreboot from the GNU Project, after a months-long dispute with the Free Software Foundation which oversees GNU.

Reception
In 2015, Kyle Rankin stated in Linux Journal that Libreboot "greatly simplified and automated" the flashing process, "with a few caveats". In 2016, Bryan Cockfield stated in Hackaday that Libreboot installation was "harrowing" and "not as easy as you'd think".
