title: Hardware compatibility list 
x-toc-enable: true
...

This sections relates to known hardware compatibility in libreboot.

For installation instructions, refer to [../install/](../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)

**WARNING: veyron speedy boards (e.g. C201) have non-functional video init as
of 19 February 2023, and no fix is yet available on that date. See:
<https://notabug.org/libreboot/lbmk/issues/136> - the last tested revision
from 2021.01 is known to work, for u-boot on this board. See:\
<https://wiki.postmarketos.org/wiki/ASUS_Chromebook_C201_(google-veyron-speedy)>
(alpernebbi on IRC is looking into this, to bisect uboot and update the latest
revisions) - for now, ROM images deleted from the Libreboot 20221214 release.**

**WARNING: daisy- and peach- boards require a BL1 bootloader blob, but the
one from coreboot 3rdparty is a fake/placeholder blob. We need logic in the
Libreboot build system for properly fetching/extracting these, plus docs to
cover it. For now, assume that these are broken - ROM images are excluded,
for now, and have been retroactively deleted from the Libreboot 20221214
release. - see: <https://review.coreboot.org/plugins/gitiles/blobs/+/4c0dcf96ae73ba31bf9aa689768a5ecd47bac19e>
and <https://review.coreboot.org/plugins/gitiles/blobs/+/b36cc7e08f7337f76997b25ee7344ab8824e268d>**

WARNING: Support for these boards is at a proof-of-concept stage. Refer
to [docs/uboot/](../uboot/) for more info about the U-Boot payload.

### Emulation

-   [Qemu x86](../misc/emulation.md)
-   [Qemu arm64](../misc/emulation.md)


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](../../faq.md#ec-embedded-controller-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:

-   [../install/#flashrom](../install/#flashrom)
-   <http://www.thinkwiki.org/wiki/BIOS_update_without_optical_disk>

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
