coreboot is a Free Software 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 recently switched to git and gerrit is now used as 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
