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!

Flashrom OK Works in coreboot

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.


  • Add cbmem -c support
  • Add ACPI support
  • make seabios detect the USB hard disks at boot


  • compatible with nvramtool


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

GNU/Linux Installation

  • To install a GNU/Linux distro on the compact flash card without an external reader,and because keyboard is not working in coreboot/SeaBIOS, I compiled coreboot in verbose mode, and put the card in the slot after coreboot said to press F12, and before the linux kernel started. I booted on an ipxe network card and installed parabola.
  • I could have used sgabios instead and pressed F12, and have booted on an ipxe network card and installed parabola
