For details development history on these boards, refer to the git log and documentation.

For boards previously supported, many fixes from upstream have been merged.

Other changes (compared to libreboot 20150518), for libreboot in general or for previously supported systems: (this is a summary. For more detailed change list, refer to the git log)

256MiB VRAM allocated on GM45 (X200, T400, T500, R400) instead of 32MiB. This is an improvement over both Lenovo BIOS and Libreboot 20150518, allowing video decoding at 1080p to be smoother. (thanks Arthur Heymans) To clarify, GM45 video performance in libreboot 20160818 is better than on the original BIOS and the previous libreboot release.

64MiB VRAM on i945 (X60, T60, MacBook2,1) now supported in coreboot-libre, and used by default (in the previous release, it was 8MiB allocated). Thanks to Arthur Heymans.

Higher battery life on GM45 (X200, T400, T500, R400) due to higher cstates now being supported (thanks Arthur Heymans). C4 power states also supported.

Higher battery life on i945 (X60, T60, MacBook2,1) due to better CPU C-state settings. (Deep C4, Dynamicl L2 shrinking, C2E).

Text mode on GM45 (X200, T400, T500, R400) now works, making it possible to use MemTest86+ comfortably. (thanks to Nick High from coreboot)

Dual channel LVDS displays on GM45 (T400, T500) are now automatically detected in coreboot-libre. (thanks Vladimir Serbinenko from coreboot)

Partial fix in coreboot-libre for GRUB display on GM45, for dual channel LVDS higher resolution LCD panels (T400, T500). (thanks Arthur Heymans)

Massively improved GRUB configuration, making it easier to boot more encrypted systems automatically, and generally a more useful menu for booting the system (thanks go to Klemens Nanni of the autoboot project). Libreboot now uses the grub.cfg provided by the installed GNU+Linux distribution automatically, if present, switching to that configuration. This is done across many partitions, where libreboot actively searches for a configuration file (also on LVM volumes and encrypted volumes). This should make libreboot more easy to use for non-technical users, without having to modify the GRUB configuration used in libreboot.

Utilities archives is now source only. You will need to compile the packages in there (build scripts included, and a script for installing build dependencies). (binary utility archives are planned again in the next release, when the new build system is merged)

SeaGRUB is now the default payload on all x86 boards. (SeaBIOS configured to load a compressed GRUB payload from CBFS immediately, without providing an interface in SeaBIOS. This way, GRUB is still used but now BIOS services are available, so you get the best of both worlds). Thanks go to Timothy Pearson of coreboot for this idea.

crossgcc is now downloaded and built as a separate module to coreboot-libre, with a universal revision used to build all boards.

Individual boards now have their own coreboot revision and patches, independently of each other board. This makes maintenance easier.

Updated all utilities, and modules (coreboot, GRUB, etc) to newer versions, with various bugfixes and improvements upstream.

RTC century byte issue now fixed on GM45 in coreboot-libre, so the date should now be correctly displayed when running the latest linux kernel, instead of seeing 1970-01-01 when you boot (thanks to Alexander Couzens from coreboot)

Build system now uses multiple CPU cores when building, speeding up building for some people. Manually specifying how many cores are needed is also possible, for those using the build system in a chroot environment. (thanks go to Timothy Pearson from coreboot)

In the build system (git repository), https:// is now used when cloning coreboot. http:// is used as a fallback for GRUB, if git:// fails.

New payload, the depthcharge bootloader (free bootloader maintained by Google) for use on the ASUS Chromebook C201. (thanks go to Paul Kocialkowski)

Various fixes to the ich9gen utility (e.g. flash component density is now set correctly in the descriptor, gbe-less descriptors now supported)

Revisions for r20150126 (relative to r20150124)

This is a bug fix release based on r20150124. It contains a few small changes:

• grub.cfg: hardcode the list of partitions to search (speeds up booting considerably. GRUB regexp isn't very well optimized)
• Docs (x200.html hcl): Remove incorrect information
• Documentation (bbb_setup.md): Fix typos
• build-release: delete ich9fdgbe_{4m,8m}.bin files from ich9gen
  • These were accidentically included in the r20150124 release. They are generated from ich9gen so it's ok, but they don't need to be in the archive.
• Documentation (grub_cbfs.md): Looping in libreboot_grub.cfg (Add notes about it if the user copied from grub.cfg in CBFS.)

Changes for this release (latest changes first, earliest changes last)

• ich9deblob: added new utility ich9gen: this can generate a descriptor+gbe image without a factory.rom dump present.
• Modified ich9deblob to use a struct for Gbe, documenting everything.
• Massively updated the ich9deblob utility: re-factored everything completely.

• resources/utilities/grub-assemble/gen.txtmode.sh: Use GNU BASH\ resources/utilities/grub-assemble/gen.vesafb.sh: Use GNU BASH
• scripts (error handling): Replace exit with exit 1 (make debugging easier)
• Move most files in CBFS to GRUB memdisk, except grub.cfg and grubtest.cfg
• docs/release.html Add DMP vortex86ex to list of candidates.
• docs/release.html Add ThinkPad X201 to list of candidates.
• New links added to docs/security/x60_security and docs/security/t60_security
• lenovobios_secondflash: Warn if BUCTS is not present. (not a dealbreaker. Can just pull out nvram battery/coin).
• lenovobios_firstflash: Fail if BUCTS fails. (anti-bricking precaution)
• Removed obnoxious warnings from flashing scripts, improved documentation instead.
• scripts (all): add proper error checking (fail fast, fail early. Do not continue if there are errors)
• buildrom-withgrub: rename image to boardname_layout_romtype.rom
• buildrom-withgrub: don't move cbfstool, execute directly
• resources/utilities/grub-assemble: add French Dvorak (BEPO) keyboard layout.
• Documentation: add docs/hardware/x60_keyboard.html (show how to replace keyboard on X60/X60T)
• Documentation: major cleanup (better structure, easier to find things)
• docs/release.html: Remove Acer CB5 from list of future candidates.

• docs/gnulinux/grub_cbfs.html Major cleanup. Usability improvements.
• flash (flashrom script): remove boardmismatch=force
  • This was put there before for users upgrading from libreboot r5 to r6, but also allows the user to flash the wrong image. For example, the user could flash a T60 image on an X60, thus bricking the system. It's almost certain that most people have upgraded by now, so remove this potentially dangerous option.
• Documentation: update compatibility list for X60T LCD panels.
• docs/release.html: add note about X60 Tablet board in X60/X60s
• docs/howtos/grub_boot_installer.html: small corrections
• docs/howtos/grub_boot_installer.html: improved readability, fixed html errors
• Documentation (macbook21 related): clean up

Revision notes (22nd June 2014)

• updated GRUB (git 4b8b9135f1, 20th April 2014)
• Made "DeJavu Sans Mono" the default font in GRUB (fixes border corruption).
• re-added background image in GRUB (meditating GNU)
• added 6 more images:
  • coreboot_ukqwerty.rom (UK Qwerty keyboard layout in GRUB)
  • coreboot_serial_ukqwerty.rom (UK Qwerty keyboard layout in GRUB)
  • coreboot_dvorak.rom (US Dvorak keyboard layout in GRUB)

  • coreboot_ukdvorak.rom (UK Dvorak keyboard layout in GRUB)
  • coreboot_serial_ukdvorak.rom (UK Dvorak keyboard layout in GRUB)
  • (coreboot.rom and coreboot_serial.rom have US Qwerty keyboard layout in GRUB, as usual)
• improved the documentation:
  • removed FLASH_INSTRUCTION and README.powertop and merged them with README
  • removed obsolete info from README and tidied it up
  • deleted README (replaced with docs/)
• tidied up the menu entries in GRUB
• tidied up the root directory of X60_source/, sorted more files into subdirectories
• improved the commenting inside the 'build' script (should make modifying it easier)
• Renamed X60_binary.tar.gz and X60_source.tar.gz to libreboot_bin.tar.gz and libreboot_src.tar.gz, respectively.
• Replaced "GNU GRUB version" with "FREE AS IN FREEDOM" on GNU GRUB start screen.
• Added sha512.txt files in libreboot_src and libreboot_bin. (inside the archives)
• Added libreboot_bin.tar.gz.sha512.txt and libreboot_src.tar.gz.sha512.txt files (outside of the archives)

Revision notes (11th June 2014):

• removed 'CD' boot option from coreboot.rom (not needed)
• removed 'processor.max_cstate=2' and 'idle=halt' options (see README.powertop file)

Revision notes (5th June 2014):

• added backlight support (Fn+Home and Fn+End) on X60
• fixed broken/unstable 3D when using kernel 3.12 or higher
• (see 'BACKPORT' file)

Revision notes (9th March 2015):

• recreated coreboot config from scratch
• GRUB loads even faster now (less than 2 seconds).
• Total boot time reduced by further ~5 seconds.
• Added crypto and cryptodisk modules to GRUB
• cbfstool now included in the binary archives

Development notes

• Binary archive now have 2 images:
  • With serial output enabled and memtest86+ included (debug level 8 in coreboot)
  • With serial output disabled and memtest86+ excluded (faster boot speeds) (debugging disabled)
• Reduced impact on battery life:
  • 'processor.max_cstate=2' instead of 'idle=halt' for booting default kernel
• coreboot.rom (faster boot speeds, debugging disabled):
  • Disabled coreboot serial output (Console-> in "make menuconfig")
  • Set coreboot debug level to 0 instead of 8 (Console-> in "make menuconfig")
  • Changed GRUB timeout to 1 second instead of 2 (in grub.cfg
  • Removed background image in GRUB.
  • Removed memtest86+ payload (since it relies on serial output)
• coreboot_serial.rom (slower boot speeds, debugging enabled):
  • Boot time still reduced, but only by ~2 seconds
  • has the memtest86+ payload included in the ROM
  • has serial port enabled. How this is achieved (from X60_source): Turn on debugging level to 8, and enable serial output
• (in Console-> in coreboot "make menuconfig")
• (and build with grub_serial.cfg and grub_memdisk_serial.cfg)

Release 20140221 (4th release) {#release20140221}

• 21st February 2014

Officially supported

• ThinkPad X60
• ThinkPad X60s

Development notes

• Removed SeaBIOS (redundant)
• New GRUB version (2.02~beta2)
  • Fixes some USB issues
  • Includes ISOLINUX/SYSLINUX parser
• New grub.cfg
• Removed useless options:
  • options for booting sda 2/3/4
  • seabios boot option
• Added new menu entries:
  • Parse ISOLINUX config (USB)
  • Parse ISOLINUX config (CD)
  • Added 'cat' module for use on GRUB command line.
• "set pager=1" is set in grub.cfg, for less-like functionality

The "Parse" options read ./isolinux/isolinux.cfg on a CD or USB, and automatically converts it to a grub config and switches to the boot menu of that distro. This makes booting ISOs *much* easier than before.
