FILO
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!
What is FILO
Filo is a bootloader which loads boot images from local filesystem, without help from legacy BIOS services.
Expected usage is to flash it into the BIOS ROM together with LinuxBIOS.
