The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
works fine with Linux, some ACPI issues with Windows needs to be fixed.

Lenovo ThinkPad T60
Have been reported to boot coreboot.
Installation and Flashing
Pre-compiled ROM images
For easy installation, you do not need to build from source to flash coreboot on the T60 - but only if it has an Intel GPU. If it has an ATI graphics chipset, then libreboot will not work.
The libreboot project has pre-compiled ROM images available which are updated regularly for this machine. These images already have the dd trick applied (for the bucts trick outlined in the link above) and the archives come with scripts to pre-patch flashrom.
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 and merged in the master repo. 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)
Non-free components replacements
Replace the non-free VGA option rom by making native graphics init work.See  (under review on 5345 changeset, review.coreboot.org]
- Create a Native graphics<->VGA option rom. SeaVGABIOS (part of SeaBIOS) might be the answer. We need to look into that.
Make backlight work without the non-free option rom.See  (under reviev 5345 changeset, review.coreboot.org)
"whining" (buzzing) noise when idle
Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB.
Note: Boot without these options, and there will be a high pitched noise coming from the board when the system is idle. A better workaround is to boot without these options, and run sudo powertop
Under "tunables", set all options to "Good" settings. This kills the noise. By using this, power consumption falls lower: near the levels in Lenovo BIOS (better battery life).
You can also use sudo powertop --auto-tune instead.
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.
This is one way to get backlight controls working. Another method is shown in changeset 6731 on review.coreboot.org. If you use this, also apply this patch to fix uneven backlight levels: patch - also, apply this patch
- 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
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
