Hardware compatibility list

Return to previous index

This sections relates to known hardware compatibility in libreboot.

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 supports the following systems in this release:

Desktops (AMD, Intel, x86)

Servers/workstations (AMD, x86)

Laptops (ARM)

Laptops (Intel, x86)

‘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, 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
