== Wifi chipsets ==
Lenovo BIOS has a whitelist of approved PCI ID's for wifi cards. Coreboot does not, so you are free to use any wifi chipset of your choosing once coreboot is installed.
The [http://libreboot.org/ Libreboot] distribution [http://libreboot.org/docs/index.html#recommended_wifi lists Wifi chipsets not needing proprietary software to work].

=== Windows currently doesn't boot (STOP A5 error) ===
Windows 7 was tested and fails to boot at the moment.
The native graphics implementation lacks INT 10H and VBT, and GRUB cannot boot it. Booting with SeaBIOS+SeaVGABIOS results in graphical corruption (and no boot).
Booting with SeaBIOS and the VGA ROM (vbios) can be used to boot it, but booting ends with the message outlined here: [http://paste.debian.net/plain/122557 STOP A5]
More information can be found [http://www.coreboot.org/ACPI#STOP_0xa5 here]
===high pitched noise from the board during low power states===
During low power state (cstate 3), a high-pitched "humming" noise eminates from the board. Some discussion has been made about this; suggestions include "using an oscilliscope in clever ways" (to detect where the noise is coming from to debug the issue). There are some workarounds:
Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB. These increase heat and power consumption.
Another option (for increased battery life and lower temperatures) is to use '''powertop --auto-tune''', or set 'Tunables' in powertop (without any parameters).
== Text Mode ==
Use [http://review.coreboot.org/#/c/6725/ this patch].
Also, enable it for T60 with [http://paste.debian.net/plain/122565 this patch]
When using native graphics instead of the VBIOS, you can enable Text Mode in menuconfig, under Display.
Disable 'Keep VESA Framebuffer'. This is for booting payloads like MemTest86+ which expect text-mode graphics.
== Make backlight (Fn keys) control work with native gpu init ==
You first need native graphics support (free VBIOS replacement). Apply [http://review.coreboot.org/#/c/5345 this patch] using '''cherry pick''' on top of master.
Before building the ROM with native graphics, in src/mainboard/lenovo/t60/devicetree.cb, change gpu_backlight to 0x58BF58BE


This value was obtained by reading BLC_PWM_CTL when running the VBIOS (option ROM), like so:

=== Non-free components replacements ===

works fine with GNU/Linux, some ACPI issues with Windows needs to be fixed.

Lenovo ThinkPad T60

Both the

  • t60p

Have been reported to boot coreboot.

Installation and Flashing

 Instructions on Installation and flashing the x60 or t60 

Wifi chipsets

Lenovo BIOS has a whitelist of approved PCI ID's for wifi cards. Coreboot does not, so you are free to use any wifi chipset of your choosing once coreboot is installed.

The Libreboot distribution lists Wifi chipsets not needing proprietary software to work.

Status

This table needs review. I copied the x60 table and ran through it from memory, expresscard comes to mind...

proprietary components status

  • CPU Microcode (optional?) - works fine without. See http://download.intel.com/design/mobile/SPECUPDT/30922214.pdf
  • VGA option rom (optional): Native graphics initialization (free replacement) is also available with this patch that is under review. Note that the replacement doesn't work yet with seabios but works with grub(as a payload) or libpayload based payloads. SeaBIOS can be used with SeaVGABIOS (coreboot linear framebuffer option in seabios menuconfig) but the native graphics implementation currently lacks INT 10H and VBT.
  • EC(Embedded Controller) => you do not have to touch it(just leave it where it is)

TODO

Non-free components replacements

  • Replace the non-free VGA option rom by making native graphics init work. See [1] (under review on 5345 changeset, review.coreboot.org]
  • Create a Native graphics<->VGA option rom. SeaVGABIOS (part of SeaBIOS) might be the answer. INT 10H and VBT are missing in native graphics.
  • Make backlight work without the non-free option rom. See 6731 on review.coreboot.org

Windows currently doesn't boot (STOP A5 error)

Windows 7 was tested and fails to boot at the moment.

The native graphics implementation lacks INT 10H and VBT, and GRUB cannot boot it. Booting with SeaBIOS+SeaVGABIOS results in graphical corruption (and no boot).

Booting with SeaBIOS and the VGA ROM (vbios) can be used to boot it, but booting ends with the message outlined here: STOP A5

high pitched noise from the board during low power states

During low power state (cstate 3), a high-pitched "humming" noise eminates from the board. Some discussion has been made about this; suggestions include "using an oscilliscope in clever ways" (to detect where the noise is coming from to debug the issue). There are some workarounds:

Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB. These increase heat and power consumption.

Another option (for increased battery life and lower temperatures) is to use powertop --auto-tune, or set 'Tunables' in powertop (without any parameters).

Text Mode

Use this patch.

Also, enable it for T60 with this patch

When using native graphics instead of the VBIOS, you can enable Text Mode in menuconfig, under Display.

Disable 'Keep VESA Framebuffer'. This is for booting payloads like MemTest86+ which expect text-mode graphics.

Make backlight (Fn keys) control work with native gpu init

You first need native graphics support (free VBIOS replacement). Apply this patch using cherry pick on top of master.

Before building the ROM with native graphics, in src/mainboard/lenovo/t60/devicetree.cb, change gpu_backlight to 0x58BF58BE

This value was obtained by reading BLC_PWM_CTL when running the VBIOS (option ROM), like so:

sudo devmem2 0xe4361254 w

Another method is shown in changeset 6731 on review.coreboot.org. If you use this method, also apply this patch to fix uneven backlight levels: patch - also, apply this patch

Other things

  • Add support for more batteries in ACPI.
  • Make the wifi card and/or the laptop produce less heat.
  • Finish and merge support for thinkpad_acpi linux kernel module
  • Sometimes some dock USB port aren't initialized => fix that
