Changes for this release of Libreboot, relative to Libreboot version 20150518 (earliest changes are shown last and the most recent changes are shown first first)
---------------------------------------------------------------------------------------------
- NEW BOARDS ADDED:
- ASUS Chromebook C201 (ARM laptop) (thanks to Paul Kocialkowski)
- Gigabyte GA-G41M-ES2L motherboard (desktop) (thanks to Damien
Zammit)
- Intel D510MO motherboard (desktop) (thanks to Damien Zammit)
- ASUS KCMA-D8 motherboard (desktop) (thanks to Timothy Pearson)
- ASUS KFSN4-DRE motherboard (server) (thanks to Timothy Pearson)
- ASUS KGPE-D16 motherboard (server) (thanks to Timothy Pearson)
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)
----------------------------------------------------------------------
- grub.cfg: Added (ahci1) to list of devices for ISOLINUX parser
(CD/DVD) (this is needed for the X200 docking station).
- grub.cfg: ISOLINUX parsing is now done on all USB partitions.
- grub.cfg: Automatically switched to /boot/grub/libreboot\_grub.cfg
on a partition, if it exists.
- libreboot\_bin: added static ARM binaries for flashrom, cbfstool,
ich9gen and ich9deblob (tested on beaglebone black).
- Flashrom: removed redundant Macronix flashchip definitions (for X200
owners).
- Flashrom: added whitelist for ThinkPad X200.
- X200: fixed uneven backlight (at low levels)
- ich9macchange (new script, uses ich9gen): for changing the default
MAC address on X200 ROM images.
- ich9gen: added capability to change the default MAC address (and
update the checksum)
- ich9deblob: added new utility ich9gen: this can generate a
descriptor+gbe image without a factory.rom dump present.

- 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

grub.cfg for each type of configuration.
- grub\_memdisk.cfg (used inside grub.elf) now only loads grub.cfg
from cbfs. It no longer enables serial output or sets prefix.
(menuentries/common.cfg does instead)

2014, when in fact it was August 11th 2014
- Fixed incorrect grub.cfg that was actually placed in
resources/grub/config/x60/grub\_usqwerty.cfg which broke the default
GRUB menu entry on X60
Revisions for r20140811 (5th beta) (11th August 2014)

deals with flashing on top of Lenovo BIOS, citing the correct dd
commands necessary if it is confirmed that the ROM has not been
applied with dd yet. (in the case that the user compiled their own
ROMs from libreboot, without using the build scripts, or if they
forgot to use dd, etc).

hardening for X60)
Revisions for r20140716 (2nd beta) (16th July 2014)
---------------------------------------------------
- Deleted all git-related files from the coreboot directory. This was
necessary because with those it is possible to run 'git diff'
which shows the changes made in the form of a patch (diff format);
this includes the blobs that were deleted during deblobbing.
Revisions for r20140711 (1st beta) (11th July 2014)
---------------------------------------------------

- updated GRUB (git 4b8b9135f1676924a8458da528d264bbc7bbb301, 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.
