'''Libreboot''' is a [[free software]] and hardware project based on [[coreboot]], aimed at replacing the proprietary [[BIOS]] [[firmware]] in most computers. Libreboot has been described as faster boot firmware for mostly older laptops. Computers with Libreboot have been marketed by several small companies selling refurbished hardware, mostly certified under the "Respects Your Freedom" certification program of the [[Free Software Foundation]]. {{Disputed inline|for=Lead needs updates to summarize body content|date=June 2023}}

== History ==
Libreboot, which began around 2013, according to "Embedded Firmware Solutions", is based on 13-years older coreboot and predecessors. Coreboot began as LinuxBIOS in 1999 at [[Los Alamos National Laboratory|Los Alamos National Labs]] (LANL), and was renamed “[[coreboot]]” in 2008. By May 2014, coreboot had 10,207 commits made by 285 contributors. When Libreboot was established as a distribution of [[coreboot]] in 2013 it was said to be "nonproprietary software distribution".<ref>{{Citation |last1=Sun |first1=Jiming |title=Building coreboot with Intel FSP |date=2015 |url=https://doi.org/10.1007/978-1-4842-0070-4_4 |work=Embedded Firmware Solutions: Development Best Practices for the Internet of Things |pages=55–95 |editor-last=Sun |editor-first=Jiming |access-date=2023-05-27 |place=Berkeley, CA |publisher=Apress |language=en |doi=10.1007/978-1-4842-0070-4_4 |isbn=978-1-4842-0070-4 |last2=Jones |first2=Marc |last3=Reinauer |first3=Stefan |last4=Zimmer |first4=Vincent |editor2-last=Jones |editor2-first=Marc |editor3-last=Reinauer |editor3-first=Stefan |editor4-last=Zimmer |editor4-first=Vincent}}</ref>

In April 2014, Dmitri Popov of [[Linux Magazine]] reviewed a refurbished IBM Lenovo ThinkPad X60 laptop purchased from Gluglug (GNU/Linux Libre User Group), which had received Respects Your Freedom hardware certification from the Free Software Foundation. Popov said the included operating system was [[Trisquel]], describing it as "a perfect match for ThinkPad X60." Popov said [[gNewSense]] or [[Parabola GNU/Linux-libre|Parabola]] were also options. Popov said the received hardware was in "decent cosmetic condition, despite being somewhat dirty, and said the boot sequence was "quick", but said removal of proprietary firmware caused hardware keys (volume, playback, and keys used with the Fn key) to not work, and the screen brightness could not be changed from 100 percent, calling it "quite a nuisance". Popov concluded, "Short battery life and the inability to adjust screen brightness make the laptop less appealing as a travel companion", old hardware means it is not good as a "primary machine", and it would be better as "a secondary machine for hacking, coding, and writing" if you remain near a power outlet.<ref>{{Cite news |last=Popov |first=Dmitri |date=April 2014 |title="An open source laptop from Gluglug, Purely Open Source" |work=[[Linux Magazine]] |url=https://www.linux-magazine.com/Issues/2014/161/Gluglug-Laptop |access-date=June 5, 2023}}</ref>

There’s no way around it: This hardware is just plain dated.</blockquote>Hoffman also said Gluglug’s developers reverse-engineered the laptop’s low-level firmware, created free software firmware to replace it, and installed that onto the laptop, but concluded "Sadly, it’ll take more than a refurbished laptop from seven years ago with reverse-engineered firmware to change the industry."<ref>{{Cite web |last=Hoffman |first=Chris |date=February 5, 2015 |title=The Free Software Foundation loves this laptop, but you won't |url=https://www.pcworld.com/article/431637/the-free-software-foundation-loves-this-laptop-but-you-wont.html |access-date=June 5, 2023 |website=PCWorld |language=en}}</ref>

In September 2015, the Free Software Foundation announced a US company called Libiquity was the first US company to receive Respects Your Freedom certification. Libiquity also contributed to Libreboot, and led development of FSF-endorsed ProteanOS.<ref>{{Cite web |date=September 30, 2015 |title=Taurinus X200 laptop now FSF-certified to respect your freedom [LWN.net] |url=https://lwn.net/Articles/658841/ |access-date=June 5, 2023 |website=lwn.net}}</ref> In September 2015, Steven Vaughan-Nichols, writing for [[ZDNET]], said Libiquity's Taurinus X200 laptop with Libreboot was "only the second laptop to be given the RYF, and it's the first to be ME (Intel Management Engine) free". Vaughan-Nichols said it had all its original low-level firmware and operating system software replaced with the free-software boot system, Libreboot, so "No trace of ME has been left", and the Trisquel operating system.<blockquote>To do this, Libreboot developers reverse engineered Intel's firmware. They then created a small software utility to produce a free firmware image that conforms to Intel's specifications. Finally, to install their firmware on the device, they used a serial peripheral interface (SPI) flasher. This is then used to completely overwrite the proprietary firmware with Libreboot and GNU GRUB 2.</blockquote>Vaughan-Nichols quoted FSF's licensing and compliance manager, Joshua Gay, who said, "With a rise in manufacturing of treacherous computing chips and each successive version of Intel's Management Engine becoming more treacherous than the last... it is refreshing to have companies like Libiquity making strong commitments to computer user freedom." Libiquity founder Patrick McDermott said they were "honored to be the first US company" to receive RYF certification".<ref>{{Cite web |last=Vaughan-Nichols |first=Steven J. |date=September 30, 2015 |title=Taurinus X200: Now the most 'Free Software' laptop on the planet |url=https://www.zdnet.com/article/a-new-free-software-laptop-arrives/ |url-status=live |archive-url=https://web.archive.org/web/20210826133134/https://www.zdnet.com/article/a-new-free-software-laptop-arrives/ |archive-date=26 August 2021 |access-date=2021-09-06 |website=[[ZDNet]] |language=en}}</ref> In September 2016, The Libiquity Taurinus X200 with Free Software Foundation approval was one of 10 laptops recommended for "Linux lovers" by Nick Heath of TechRepublic.<ref>{{Cite web |last=Heath |first=Nick |date=2016-09-23 |title=Fed up with Windows 10?

In May 2018, Erik Bärwaldt of linux-magazine.com wrote,<blockquote>Several small international companies have emerged around free BIOS implementations. These vendors fill the niche of providing computers for users who want a system that is truly all free. They can also offer the benefit of faster boot time with a trimmed down system, and they are in a unique position to avoid the planned obsolescence of the computer industry by maintaining support for older systems that are no longer relevant to the big hardware vendors.</blockquote> Bärwaldt reviewed a Lenovo ThinkPad T400 notebook, purchased from Minifree and certified by the Free Software Foundation under the "Respects Your Freedom" program, with Trisquel and Libreboot preinstalled. Bärwaldt described Libreboot as having some proprietary [[binary blob]]s removed from coreboot, and said the more than eight years old laptop looked "almost as good as new". According to Bärwaldt, the Libreboot BIOS was "significantly" faster, and Trisquel boots "considerably" faster, compared with other systems on "similar hardware". Bärwaldt said there were weaknesses where proprietary blobs and firmware had not yet been replaced with free components.<ref name=":0">{{Cite web |last=Bärwaldt |first=Erik |date=May 2018 |title=Liberated » Linux Magazine |url=http://www.linux-magazine.com/Issues/2018/210/Free-Firmware-with-Libreboot |url-status=live |archive-url=https://web.archive.org/web/20210822203232/https://www.linux-magazine.com/Issues/2018/210/Free-Firmware-with-Libreboot |archive-date=22 August 2021 |access-date=2021-08-22 |website=[[Linux Magazine]] |language=en-US}}</ref>

According to analysis presented by Denis Carikli, when the former Libreboot team began adding non-free software, and the differences could not be resolved, a new Libreboot effort with support of FSF, GNU, Technoethical and others, was started.<ref>{{Cite web |title=Libreboot - Free Software Directory |url=https://directory.fsf.org/wiki/Libreboot |access-date=2023-05-27 |website=directory.fsf.org}}</ref><ref>{{Cite web |title=Taking control over the means of production: Free software boot — GNU MediaGoblin |url=https://media.libreplanet.org/u/libreplanet/m/taking-control-over-the-means-of-production-free-software-boot/ |access-date=2023-05-27 |website=media.libreplanet.org}}</ref>

Libreboot (briefly known as GNU Libreboot[3][4]) is a free and open-source software project based on coreboot, aimed at replacing some of the proprietary BIOS or UEFI firmware on supported X86-64- and AArch64-based computers. Libreboot performs the basic machine setup such as CPU initialization or memory controller initialization necessary to load and run a 32-bit or 64-bit operating system, such as Linux or FreeBSD.

Characteristics

[edit]

Libreboot is established as a distribution of coreboot, but with some[5] proprietary binary blobs removed from coreboot.[6] Libreboot makes coreboot easy to use by automating the build and installation processes.[7][8][9][10]

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.[11] Hardware support includes but is not limited to the ASUS KGPE-D16,[12] ThinkPad T400,[13][14] X60[7][8] and X200.[14][15] Libreboot is officially endorsed by the upstream coreboot project.[16]

History

[edit]

The Libreboot project was started in December 2013[6] 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.[17]

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.[18][19]

Reception

[edit]

In 2015, Kyle Rankin stated in Linux Journal that Libreboot "greatly simplified and automated" the flashing process, "with a few caveats".[7][8] In 2016, Bryan Cockfield stated in Hackaday that Libreboot installation was "harrowing" and "not as easy as you'd think".[9]
