Welcome to coreboot
The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
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. Please read the gerrit etiquette & guidelines document before submitting or reviewing patches.
