Installation instructions can be found at docs/install/. Building instructions (for source code) can be found at docs/git/#build.

Machines supported in this release:

  • ThinkPad X60/X60s
    • You can also remove the motherboard from an X61/X61s and replace it with an X60/X60s motherboard. An X60 Tablet motherboard will also fit inside an X60/X60s.
  • ThinkPad X60 Tablet (1024x768 and 1400x1050) with digitizer support
    • See docs/hardware/#supported_x60t_list for list of supported LCD panels
    • It is unknown whether an X61 Tablet can have it's mainboard replaced with an X60 Tablet motherboard.
  • ThinkPad T60 (Intel GPU) (there are issues; see below):
    • See notes below for exceptions, and docs/hardware/#supported_t60_list for known working LCD panels.
    • It is unknown whether a T61 can have it's mainboard replaced with a T60 motherboard.
    • See docs/future/#t60_cpu_microcode.
    • T60p (and T60 laptops with ATI GPU) will likely never be supported: docs/hardware/#t60_ati_intel

Changes for this release, relative to r20150208 (earliest changes last, recent changes first)

  • Add a whitelist entry to board_enable.c in flashrom, for the ThinkPad R400, T400 and T500
  • Updated flashrom (to SVN revision 1889)
    • X200 whitelist patch removed (merged upstream)
    • X200 whitelist modified to include X200S and X200 Tablet
  • libreboot_util: don't include cmos layout files (not needed anymore)
  • coreboot-libre: backport patches for X200 Tablet digitizer support
  • build/release/archives: create SHA512 sum manifest file of the release archives
  • build/release/archives: separate crossgcc into a new archive
  • disabled generation of txtmode ROM images for now (they will be back again in the next release)
  • coreboot-libre: delete unused code (reduce size of src archive)
  • Flashing guides: make them more friendly to colourblind people
  • docs/linux/encrypted_*.html: Remove mention of password length - it was arbitrary and pointless.
  • docs/maintain/: Finish the guide
  • scripts/download/coreboot: use diffs included in libreboot, not external gerrit cherry-picks - review.coreboot.org (gerrit) being down no longer kills libreboot (backup mirrors of the master repository exist)
  • docs/install/bbb_setup.html: Add info about wp/hold and pinouts
  • docs/: improve the description of libreboot
  • docs/hardware/gm45_remove_me.html: notes about the demefactory utility

  • Update coreboot(again) + merge GM45 hybrid GPU patches - means that T400/T500 with the ATI+Intel hybrid GPU setup will work (ATI disabled, Intel permanently enabled). power_on_after_fail nvram option added to all GM45 boards, defaulting to No, so that plugging it AC doesn't boot up the system against the users will.
