== BIOS and UEFI==

[[File:Coreboot+seaBIOS+on-x60.JPG|thumb|upright|[[SeaBIOS]], an open-source implementation of BIOS, running as coreboot payload on a Lenovo [[ThinkPad]] X60]]

The [[BIOS]], which functions as a [[bootloader]] and supports legacy [[real mode]] applications, is a crucial component of many [[IBM-compatible]] computers. The BIOS can be a security [[Backdoor (computing)|backdoor]].<ref>{{cite web|url=http://www.intel.com/content/www/us/en/architecture-and-technology/vpro/vpro-technology-general.html |title=Intel vPro Technology |publisher=Intel.com |date=2012-05-14 |access-date=2014-04-10}}</ref><ref>{{cite web|url=https://www.absolute.com/en/partners/bios-compatibility.aspx |title=BIOS & Firmware Compatibility |publisher=Absolute.com |access-date=2014-04-10}}</ref>{{failed verification|date=April 2014}} In the late 1990s work started on EFI (Extensible Firmware Interface) with the objective to move legacy BIOS to a modern interface with a modular driver model. EFI is closed source and was eventually adopted by many industry leading hardware manufacturers as [[UEFI]] (Unified Extensible Firmware Interface). The EDK (EFI Development Kit) was developed to assist EFI firmware development projects.<ref name="Apress">{{cite book |authors author= Vincent Zimmer, |author2=Jiming Sun, |author3=Marc Jones & |author4=Stefan Reinauer |date= 2015 |title= Embedded Firmware Solutions: Development Best Practices for the Internet of Things |publisher= Apress |isbn= 9781484200704 | page = 121}}</ref>

Also in the late 1990s, the [[coreboot]] project was started to create an open source alternative to legacy BIOS from scratch.<ref name="Apress"/> The coreboot developer community organises around [[Stefan Reinauer]] and is led by firmware developers with commit rights.<ref>{{cite book |authors author= Vincent Zimmer, |author2=Jiming Sun, |author3=Marc Jones & |author4=Stefan Reinauer |date= 2015 |title= Embedded Firmware Solutions: Development Best Practices for the Internet of Things |publisher= Apress |isbn= 9781484200704 | page = 61}}</ref> Despite closed source binary firmware having been at the heart of the [[x86]] architecture coreboot only incorporates the few proprietary binaries that are necessary to provide users with a base level hardware support.<ref>{{cite book |authors author= Vincent Zimmer, |author2=Jiming Sun, |author3=Marc Jones & |author4=Stefan Reinauer |date= 2015 |title= Embedded Firmware Solutions: Development Best Practices for the Internet of Things |publisher= Apress |isbn= 9781484200704 | page = 65}}</ref> A completely open source alternative to BIOS and UEFI is [[libreboot]], which was promoted by the [[Free Software Foundation]] (FSF).<ref>{{cite web|url=https://www.fsf.org/campaigns/free-bios.html|title=Campaign for Free BIOS|publisher=Free Software Foundation|date=2006-11-29|access-date=2007-01-02}}</ref>
