Wake on keyboard Unknown Is there wake on keyboard on this board?
Wake on mouse Unknown Is there wake on mouse on this board?
Flashrom OK Works in coreboot, be sure to run "modprobe msr" before.

Proprietary componemts status

  • VSA: LGPL but require a microsoft compiler. Code need to be converted, openvsa froze the board during boot(but it was tried with my distro's compiler).
  • Has a free video option rom that can be generated by seabios, i didn't succeed at getting it work.

TODO

  • Retest the following: Audio, Second serial port, USB under GNU/Linux, they were tested with an old revision, before the board status system.
  • Test untested things in "Status"
  • Make fallback mecanism compile and work.
  • Add ACPI support and make seabios detect the USB hard disks at boot.

Coreboot features

  • Compatible with nvramtool.

Recovery

  • There is an LPC dongle with a socketed second BIOS chip in it, it can probably be bought, lent or given by the company making the card.

GNU/Linux Installation

USB doesn't work under SeaBIOS with this board, so pressing F12 from an USB keyboard to boot on an USB key won't work for now.

  • If you have no compact flash reader, you add ipxe and sgabios to the coreboot image in order to boot from the network. Sgabios is needed to be able to press F12 in SeaBIOS trough the serial port.
  • SeaBIOS do run external option roms, like the ones on network cards.
  • Removing the compact flash card before SeaBIOS makes SeaBIOS boot on the next available device (like a network card with ipxe), and putting it back before the linux kenrel boot makes it appear under GNU/Linux.
