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!

This page describes how to use Coreboot on the Sun Ultra 40 M2 mainboard. It is maintained by jakllsch and seait.
