'''LinuxBIOS''' is a Free Software project aimed at replacing the proprietary BIOS (firmware) you can find in most of today's computers.
'''coreboot''' is an Open Source project aimed at replacing the proprietary [http://wikipedia.org/wiki/BIOS BIOS] (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a [[Payloads|payload]].


It performs just a little bit of hardware initialization and then executes a so-called [[Payloads|payload]], for example a [[Linux]] kernel, [[FILO]], [[GRUB2]], [http://www.openbios.org/ OpenBIOS], [http://www.openbios.org/Open_Firmware Open Firmware], [http://www.openbios.org/SmartFirmware SmartFirmware], [http://www.gnu.org/software/gnufi/ GNUFI] (UEFI), [[Etherboot]], [[ADLO]] (for booting [http://en.wikipedia.org/wiki/Windows_2000 Windows 2000] and [http://openbsd.org/ OpenBSD]), [[Plan 9]], or [[memtest86]].
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly from firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like [[SeaBIOS | PC BIOS services]] or [[TianoCore | UEFI]]. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
 
coreboot currently supports over '''[[Supported Motherboards|230]]''' different mainboards. Check the [[Support]] page to see if your system is supported.

coreboot is an Open Source project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.

With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly from firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.

coreboot currently supports over 230 different mainboards. Check the Support page to see if your system is supported.

coreboot was formerly known as LinuxBIOS.

coreboot uses git for source control and gerrit as the patch review tool.

  • 100% Free Software (GPL), no royalties, no license fees!
  • Fast boot times (500 milliseconds to verified Linux kernel)
  • Supports many mainboards, chipsets, and payloads
