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 Contributions welcome!

This page gives you hints on how to test the coreboot support for your mainboard and all components present on the board.

We try to maintain one build tutorial / status page for every supported coreboot mainboard. The status table is always implemented using the status template in this wiki. A usage example is available, but you can also look at existing status pages.

For each item in the status table, this page describes how you can test the respective hardware part.



On-board hardware


IDE 3.5"

IDE 2.5"


On-board USB

  • Test at least one "full-speed" (USB 1.1) device (e.g. USB keyboard) and one "hi-speed" (USB 2.0) device (e.g. DVB-T adapter).
  • Test both of the above devices on all available USB connectors. This includes the usual on-board connectors, but there may also be pin headers on the board where you can add further USB connectors.

Add-on slots/cards

Legacy / Super I/O

Parallel port

  • Try loading the ppdev and parport_pc kernel modules: modprobe ppdev; modprobe parport_pc. Check if there were errors using dmesg.
  • Try to actually use a parallel port device (e.g. a printer).
  • If there are errors/problems, please post the superiotool -dV output on the mailing list and ask the developers for help.

PC speaker

  • Try to create a beep on the PC speaker. There are various ways to do that, e.g. you can use the Debian package beep (apt-get install beep).
  • If that doesn't work, check that you actually have a speaker correctly attached and also try modprobe pcspkr.
