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 ASUS P2B-DS mainboard. It is maintained by Uwe Hermann.
