* Note, not all T60 lcd panels work with this configuration. (the code to enable native graphics on T60 is still under review), check [http://libreboot.org/docs/hcl/index.html#supported_t60_list compatibility list]
* Note, if your LCD panel is unsupported, you can still use this configuration; you won't see any graphics on the screen, but an external monitor will work (using VGA output, or DVI if you have the docking station). For GRUB console, you can use serial output or EHCI debug. Recommended docking station: Advanced Mini Dock.
* Note, replacing the LCD panel is relatively easy. The libreboot project has some guides in it's documentation, along with info about what LCD panels are known to work.
* Note, this configuration only works for T60's with the Intel GMA950 video chipset. ATI GPU won't work, because they lack native graphics support.

Coreboot supports all ThinkPad T60/T60p Series laptops.

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 for models with a Intel gpu.
  • EC(Embedded Controller) => you do not have to touch it(just leave it where it is)

Building the ROM without proprietary blobs

TODO: these instructions should still work, but they are outdated. Bring them up to date, using the latest coreboot revision.

This basically means:

  • No microcode updates
  • Native graphics (replacement for the proprietary Video BIOS / VGA Option ROM)
  • GRUB2 payload

In this configuration, only GNU/Linux is known to work. If you plan to use other operating systems, you might be out of luck.

  • Note, this configuration only works for T60's with the Intel GMA950 video chipset. ATI GPU won't work, because they lack native graphics support.

Download coreboot like usual: 

git clone http://review.coreboot.org/coreboot
cd coreboot

At the time of writing for (for these instructions), the following git revision was used: 

Install all of the coreboot build dependencies listed at [http://www.coreboot.org/Build_HOWTO Build_HOWTO] and then build the crossgcc toolchain:
<pre>
make crossgcc-i386

Now you will want this basic configuration for X60/X60s (in make menuconfig): 

    General setup / Expert mode = enable
    General setup / Local version string = 79ETE7WW (2.27 )
    Mainboard / Mainboard vendor = Lenovo
    Mainboard / Mainboard model = ThinkPad T60 / T60p
    Mainboard / ROM chip size = 2048 KB (2 MB)
    Mainboard / SMBIOS Serial Number = L3DKE06
    Mainboard / SMBIOS Version Number = ThinkPad T60
    Mainboard / SMBIOS Manufacturer = LENOVO
    Mainboard / SMBIOS Product name = 1951FEG
    Chipset / Include CPU microcode in CBFS = Do not include microcode updates
    Devices / Use native graphics initialization = enable
    Display / Keep VESA framebuffer = disable (disable for text-mode graphics, enable for coreboot vesa framebuffer)
    Console / Send console output to a CBMEM buffer = enable
    Payload / Add a payload = An ELF executable payload
    Payload / Payload path and filename = grub.elf

Go back into Devices:

    Devices / Run VGA Option ROMs = disable
    Devices / Run Option ROMs on PCI devices = disable


SMBIOS values were taken by running dmidecode with the factory BIOS.

Note, the above assumes that you already built your grub.elf from source along with everything that you need. Building GRUB is not covered here.

Put your grub.elf in the coreboot directory and then run make. Alternatively, you could go back into menuconfig and select coreboot's own GRUB payload config, which will automatically download and build the GRUB payload. Building it yourself can be more flexible, though, since you get to choose what modules you want and you can use your own configs.

T60 with ATI Mobility Radeon

Model with an ATI gpu need an option for display to work. To do this look up the pci id using lspci and adapt CONFIG_VGA_BIOS_ID in menuconfig accordingly. e.g. "1002,7145"

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. The CPU noise on core duo CPUs is highly reduced by https://review.coreboot.org/#/c/16901/ and likely was not a problem on core 2 duo CPUs.

Another option (for increased battery life and lower temperatures) is to use powertop --auto-tune, or set 'Tunables' in powertop (without any parameters). This solves noise coming from the USB ports which is not related to the CPU low power states.

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
