Hardware compatibility list


Return to previous index

This sections relates to known hardware compatibility in libreboot. Osboot merged with and became part of Libreboot on November 15th, 2022. As of this day, November 16th, many new boards have been added as a result, but some may not be documented or even listed at all (on this page). If any are missing, please tell us on IRC.

If a target doesn’t yet have ROM images in the release (ones present as a result of the osboot merge), please know that the Libreboot 20220710 release was conducted before the merge. The next release after Libreboot 20220710 shall contain ROM images for these additional boards.

For installation instructions, refer to ../install/.

NOTE: For T60/R60 thinkpads, make sure that it has an Intel GPU, not an ATI GPU because coreboot lacks native video initialization for the ATI GPUs on these machines.

(for later machines like T500, T400, ATI GPU doesn’t matter, because it also has an Intel GPU, and libreboot uses the Intel one)

Supported hardware

libreboot currently supports the following systems in this release:

Desktops (AMD, Intel, x86)

Servers/workstations (AMD, x86)

Laptops (Intel, x86)

Laptops (ARM, u-boot, MOSTLY UNTESTED AS OF NOVEMBER 16, 2022)

NOTE: ARM hardware is currently undocumented in Libreboot, both for installation of Libreboot and the installation of an operating system. If you have one of these machines configured with Libreboot, you should consult u-boot documentation to learn how it’s operated. You might ping alpernebbi on Libera IRC, who ported these boards to Libreboot. Extensive work was performed, to make u-boot work correctly. TODO: installation instructions must be added to documentation!

Emulation

TODO: More hardware is supported. See resources/coreboot/ in lbmk. Update the above list!

‘Supported’ means that the build scripts know how to build ROM images for these systems, and that the systems have been tested (confirmed working). There may be exceptions; in other words, this is a list of ‘officially’ supported systems.

EC update on i945 (X60, T60) and GM45 (X200, X301, T400, T500, R400, W500, R500)

It is recommended that you update to the latest EC firmware version. The EC firmware is separate from libreboot, so we don’t actually provide that, but if you still have Lenovo BIOS then you can just run the Lenovo BIOS update utility, which will update both the BIOS and EC version. See:

NOTE: this can only be done when you are using Lenovo BIOS. How to update the EC firmware while running libreboot is unknown. libreboot only replaces the BIOS firmware, not EC.

Updated EC firmware has several advantages e.g. better battery handling.

How to find what EC version you have (i945/GM45)

In GNU+Linux, you can try this:

grep 'at EC' /proc/asound/cards

Sample output:

ThinkPad Console Audio Control at EC reg 0x30, fw 7WHT19WW-3.6

7WHT19WW is the version in different notation, use search engine to find out regular version - in this case it’s a 1.06 for x200 tablet
