<h1 id="why">What is libreboot, really?</h1>
<h2>
Project goals (and differences versus coreboot):
</h2>
<ul>
<li>
Coreboot contains blobs (proprietary data/code) and libreboot does not (it intentionally removes them).
</li>
<li>
Coreboot is hacker-friendly and focuses on software developers, libreboot is user-focused and attempts to
turn coreboot into a distribution, sort of like a GNU/Linux distribution (same concept, different software). For example, libreboot
distributes GRUB/memtest86+/bucts (and more) and comes with user-focused documentation and build scripts; libreboot
is therefore made more 'user-friendly'.
</li>
</ul>
<p>
Libreboot is <b>not</b> a fork of coreboot, despite misconceptions of this fact. Libreboot (downstream supplier) is a parallel effort
which works closely with and re-bases on the latest coreboot (upstream supplier) every so often.
</p>
<p>
<b>
As such, all new coreboot development should be done in coreboot, not libreboot!
Libreboot is about deblobbing, and packaging coreboot in a user-friendly way, where most work is already done for the user!
If, for example you wanted to attempt porting a new motherboard then you should do that in coreboot. Libreboot will (as a downstream)
receive your change at some point in the future, in a future release.
</b>
</p>
<h2>
A 'stable' coreboot:
</h2>
<ul>
<li>
Coreboot uses the <a href="https://en.wikipedia.org/wiki/Rolling_release">rolling release</a> model
(and it is therefore quite volatile; one day when you build coreboot, it may or may not work correctly on your machine).
</li>
<li>
Libreboot changes less often (as far as the release model is concerned), focusing instead on 'tested' releases for <i>specific machines</i>
At any given time, it might also be possible to build ROM images for systems other than those officially supported. If you get your board to work
(without violating the <i>"coreboot development goes in coreboot"</i>, then others could benefit from your work.
</li>
</ul>
<p>
On the other hand, coreboot is also strict about what it accepts (merges) into the main git repository:
most of the time, a lot of changes are under review at review.coreboot.org (as a way of encouraging as much further development
as possible before accepting the patch).
</p>
<p>
Meanwhile, libreboot is a lot less strict in this area and freely merges specific patches that are desirable, sometimes before they are merged into coreboot's main repository.
</p>
<p><a href="#pagetop">Back to top of page.</a></p>
<hr/>
<h1 id="build_dependencies">Install build dependencies</h1>
<p>
Before doing anything, you need the dependencies first.
</p>
<ul>
<li><b>deps-trisquel</b> script installs dependencies for Trisquel 6 (also tested in Trisquel 7).</li>
<li><b>deps-parabola</b> script installs dependencies for Parabola</li>
</ul>
<p>
For all other GNU/Linux distributions, you may have to adapt these scripts. By all means send patches!
</p>
<p><a href="#pagetop">Back to top of page</a></p>
<hr/>
<h1 id="build_meta">Get the full source code from metadata (git clone)</h1>
<p>
If you downloaded libreboot from git, then there are some steps to download and patch
the source code for all relevant dependencies. The archive in the git repository used to be
available as a tarball called 'libreboot_meta.tar.gz'. It contains 'metadata' (scripts)
which define how the source was created (where it came from).
</p>
<p>
You can use the scripts included to dwnload everything.
</p>
<p>
First, <a href="#build_dependencies">install the build dependencies</a>.
</p>
<p>
After that, run the get script:<br/>
<b>$ ./getall</b>
</p>
<p>
What this did was download everything (grub, coreboot, memtest86+, bucts, flashrom)
at the versions last tested for this release, and patch them. Read the script
in a text editor to learn more.
</p>
<p>
To build the ROM's, see <a href="#build">#build</a>.
</p>
<p><a href="#pagetop">Back to top of page.</a></p>
<hr/>
<h1 id="build_bucts">How to build "bucts" (for LenovoBIOS X60/X60S/X60T/T60)</h1>
<p>
<b>This is for Lenovo BIOS users on the ThinkPad X60/X60S, X60 Tablet and T60. If you have coreboot or libreboot running already, ignore this.</b>
</p>
<p>
Bucts is needed when flashing in software the X60/X60S/X60T/T60 ROM while Lenovo BIOS is running;
external flashing will be safe regardless.
Each ROM contains identical data inside the two final 64K region in the file.
This corresponds to the final two 64K regions in the flash chip. Lenovo BIOS will prevent you from writing the
final one, so running "<b>bucts 1</b>" will set the machine to boot from the other block instead (which
is writeable along with everything beneath it when using a patched flashrom. see <a href="#build_flashrom">#build_flashrom</a>).
After shutting down and booting up after the first flash,
the final 64K block is writeable so you flash the ROM again with an unpatched flashrom and run "<b>bucts 0</b>" to
make the machine boot from the normal (highest) block again.
</p>
<p>
BUC.TS utility is included in libreboot_src.tar.gz and libreboot_bin.tar.gz.<br/>
<b>If you downloaded from git, follow <a href="#build_meta">#build_meta</a> before you proceed.</b>
</p>
<p>
"BUC" means "<b>B</b>ack<b>u</b>p <b>C</b>ontrol" (it's a register) and "TS" means "<b>T</b>op <b>S</b>wap"
(it's a status bit). Hence "bucts" (BUC.TS). TS 1 and TS 0 corresponds to bucts 1 and bucts 0.
</p>
<p>
First, <a href="#build_dependencies">install the build dependencies</a>.
</p>
<p>
To build bucts, do this in the main directory:<br/>
<b>$ ./builddeps-bucts</b>
</p>
<p>
The "builddeps" script in libreboot_src also makes use of builddeps-bucts.
</p>
<p><a href="#pagetop">Back to top of page.</a></p>
<hr/>
<h1 id="build_flashrom">How to build "flashrom"</h1>
<p>
Flashrom is the utility for flashing/dumping ROM's. This is what you will use to install libreboot.
</p>
<p>
Flashrom source code is included in libreboot_src.tar.gz and libreboot_bin.tar.gz.<br/>
<b>If you downloaded from git, follow <a href="#build_meta">#build_meta</a> before you proceed.</b>
</p>
<p>
First, <a href="#build_dependencies">install the build dependencies</a>.
</p>
<p>
To build it, do that in the main directory:<br/>
<b>$ ./builddeps-flashrom</b>

<h1 id="config">Configuring libreboot</h1>
<p>
Before building a ROM in libreboot (or coreboot, for that matter), you need to configure it.
This is done using the following inside the source tree:<br/>
<b>$ make menuconfig</b>
</p>
<p>
If you've already built a kernel before, you know how to use this interface.
</p>
<p>
Configurations are then saved as files called <b>".config"</b>. Copies of each configuration used
for each machine type by the libreboot build scripts are stored in resources/libreboot/config/
</p>
<h2 id="config_dmidecode">
dmidecode
</h2>
<p>
There is certain information that can be useful to enter in particular:
</p>
<ul>
<li>Local version string</li>
<li>SMBIOS Serial Number</li>
<li>SMBIOS Manufacturer</li>
<li>SMBIOS Version</li>
<li>SMBIOS Product name</li>
</ul>
<p>
This information can be obtained using:<br/>
<b>$ sudo dmidecode</b><br/>
<b># dmidecode</b>
</p>
<p>
Specifically, it's good practise to enter the same information for libreboot that you found when running this
with the original BIOS or firmware. <b>libreboot has already done this for you. This information is for reference,
in the hope that it will be useful.</b>

<h1 id="build">How to build the ROM's!</h1>
<p>You don't need to do much, as there are scripts already written for you that can build everything automatically.</p>
<p>
First, <a href="#build_dependencies">install the build dependencies</a>.
</p>
<p>If running for the first time, run this:<br/>
<b>$ ./buildall</b> (also performs the "./build" step below)<br/>
Or if you only want to build dependencies (crossgcc, grub and so on):<br/>
<b>$ ./builddeps</b></p>
<p>If you've already run ./builddeps and/or ./buildall before, you don't need to run them again.
Just run that from now on to build your ROM's:<br/>
<b>$ ./build</b></p>
<p>To un-build (clean) the build dependencies that you built before, do the following:<br/>
This also deletes the ROM images under ./bin/:<br/>
<b>$ ./cleandeps</b></p>
<p>Note: after running 'cleandeps', you will need to run 'builddeps' or 'buildall' again before you can use 'build'.</p>
<p>After 'build' or 'buildall' has finished, you'll find the ROM images for each machine under ./bin/</p>
<h2>Preparing release archives (optional)</h2>
<p>
Run that script:<br/>
<b>$ ./build-release</b>
</p>
<p>
You'll find that the files libreboot_bin.tar.xz and libreboot_src.tar.xz have been created.

<p><a href="#pagetop">Back to top of page</a></p>

<h1 id="build_addseabios">How to add SeaBIOS to your ROM's</h1>
<p>
SeaBIOS isn't really needed since libreboot uses the GRUB payload which
is much better (for several reasons), so it is no longer included in the ROM
images by default. Instead, you can add it afterwards.
</p>
<p>
In the supplied binary archives, or in your own (if you did 'build-release') you can add SeaBIOS
to the ROM images, along with SeaVGABIOS which is a free/libre Video BIOS implementation that wraps
around the 'native graphics initializitation' code in coreboot, for boards that have support for it.
</p>
<p>
First, <a href="#build_dependencies">install the build dependencies</a>.
</p>
<p>
Build cbfstool:<br/>
$ <b>./builddeps-cbfstool</b>
</p>
<p>
Now:<br/>
$ <b>./addseabios</b>
</p>
<p>
SeaBIOS and SeaVGABIOS (which the build scripts created, and the build-release script put - compiled -
inside the binary archive) have now been added to all of the ROM images under ./bin/. A GRUB menuentry will show
up when you boot your machine, allowing you to use SeaBIOS.

'Supported' means that the build scripts know how to build ROM's for these machines,
and that the machines have been tested (confirmed working). There may be exceptions;
in other words, this is a list of 'officially' supported machines.

<p>
The T60 typically comes with an Intel wifi chipset which does not work at all without proprietary firmware, and while Lenovo BIOS is running
the machine will refuse to boot if you replace the card. Fortunately it is very easily replaced;
just remove the card and install another one <b>after</b> libreboot is installed. See <a href="#recommended_wifi">#recommended_wifi</a> for replacements.

<h1 id="t60_ati_intel">ThinkPad T60 (ATI GPU) and ThinkPad T60 (Intel GPU) differences.</h1>
<p>
If your T60 is a 14.1" or 15.1" model with an ATI GPU, it won't work with libreboot by default but
you can replace the motherboard with another T60 motherboard that has an Intel GPU, and then libreboot should work.
</p>
<p>
As far as I know, 14.1" (Intel GPU) and 15.1" (Intel GPU) T60 motherboards are the same, where
'spacers' are used on the 15.1" T60. In any case, it makes sense to find one that is guaranteed to fit in your chassis.
</p>
<p>
There is also a 15.4" T60 with Intel GPU.
</p>
<p>
Note: the T60<b>p</b> laptops all have ATI graphics.
The T60p laptops cannot be used with libreboot under any circumstances.
</p>
<p>
The following T60 motherboard (see area highlighted in white) shows an empty space where the ATI GPU would be (this particular motherboard has an Intel GPU):
<img src="howtos/t60_dev/t60_unbrick.jpg" alt="" />
</p>
<p>
The reason that the ATI GPU on T60 is unsupported is due to the VBIOS (Video BIOS) which is non-free.
The VBIOS for the Intel GPU on X60/T60 has been reverse engineered, and replaced with Free Software and
so will work in libreboot.
</p>
<p>
The 'Video BIOS' is what initializes graphics.
</p>
<p>
See: <a href="https://en.wikipedia.org/wiki/Video_BIOS">https://en.wikipedia.org/wiki/Video_BIOS</a>.<br/>
In fact, lack of free VBIOS in general is a big problem in coreboot, and is one reason (among others) why many ports for coreboot are
unsuitable for libreboot's purpose.
</p>
<p>
Theoretically, the ThinkPad T60 with ATI GPU can work with libreboot and have ROM's compiled for it, however
in practise it would not be usable as a laptop because there would be no visual display at all. That being said,
such a configuration is acceptable for use in a 'headless' server setup (with serial and/or ssh console as the display).

<h1 id="macbook11">Information about the macbook1,1</h1>
<p>
There is an Apple laptop called the macbook1,1 from 2006 which uses the same i945 chipset as the ThinkPad X60/T60.
A developer ported the <a href="#macbook21">MacBook2,1</a> to coreboot, the ROM images also work on the macbook1,1.
</p>
<p>
You can refer to <a href="#macbook21">#macbook21</a> for most of this. Macbook2,1 laptops come with Core 2 Duo processors
which support 64-bit operating systems (and 32-bit). The MacBook1,1 uses Core Duo processors (supports 32-bit OS but not 64-bit),
and it is believed that this is the only difference.
</p>
<p>
It is believed that all models are compatible, listed here:

<h1 id="macbook21">Information about the macbook2,1</h1>
<p>
There is an Apple laptop called the macbook2,1 from late 2006 or early 2007 that uses the same i945 chipset
as the ThinkPad X60 and ThinkPad T60. A developer ported coreboot to his macbook2,1, and now libreboot can run on it.
</p>
<p>
Mono Moosbart is the person who wrote the port for macbook2,1. Referenced below are copies (up to date at the time of writing, 20140630)
of the pages he wrote when porting coreboot to the macbook2,1. They are included here in case the main site goes down for
whatever reason, since they include a lot of useful information.

<p>
How to boot an ISO: burn it to a CD (like you would normally) and hold down the Alt/Control key while booting.
The bootloader will detect the GNU/Linux CD as 'Windows' (because Apple doesn't think GNU/Linux exists). Install it like you normally would.
When you boot up again, hold Alt/Control once more. The installation (on the HDD) will once again be seen as 'Windows'. (it's not actually Windows,
but Apple likes to think that Apple and Microsoft are all that exist.)

Bus Pirate recommended for external flashing (there are others) and needed tools: clip (eg Pomona 5250), mini usb cable,
bus pirate cable (for connecting Pomona to the bus pirate).
</p>
<p>
You need to replace OS X with GNU/Linux before flashing libreboot. (OSX won't run at all in libreboot).
</p>
<p>
There are some issues with this machine (compared to other computers that libreboot supports):
</p>
<p>
This is an apple laptop, so it comes with OS X: it has an Apple keyboard, which means that certain keys you expect are missing:
insert, del, home, end, pgup, pgdown. There is also one mouse button only. Battery life is poor compared to X60/T60 (for now).
It also has other issues: for example, the Apple logo on the back is a hole, exposing the backlight, which means that it glows. You should cover it up.
</p>
<p>
The macbook21 gets extremely hot under GNU/Linux and libreboot; Macfanctld (mac fan control daemon) I'm told is a programme (GPLv3 license) that can help with this.
</p>
<p>
Debugging the heating issues (initial work):<br/>
Distro: Trisquel 7. kernel(linux-libre): 3.13.0-32<br/>
<b>CPU temperatures:</b><br/>
52C(idle)/81C(stress) on factory.bin<br/>
70C(idle)/80C(stress) on coreboot(with microcode updates). libreboot results (without microcode updates) were the same.<br/>
(libreboot and coreboot rom's were both built from the same code, just with or without microcode included in the rom)<br/>
battery life was higher on original firmware, lower on coreboot/libreboot.<br/>
microcode patches included [y/n] makes no difference.<br/>
libreboot: 1hr18min left on idle (99% battery), 42mins left on stress (82% battery)<br/>
factory.bin: 2 hours left on idle (99% battery), 48mins left on stress (82% battery)
</p>
<p>
mtjm: see what Macbook's vendor boot firmware has in its ACPI tables?<br/>
fchmmr: if this works, I'll add the patch to libreboot proper, and udpate the build scripts to use it (also, I should submit the change upstream)<br/>
fchmmr: mtjm, how do I do that?<br/>
mtjm: (I don't know if these values are generic or specific to something)<br/>
mtjm: fchmmr: get them, decompile, read, use the spec to understand what _CST does; acpidump and iasl help<br/>
so, acpidump and then iasl -d ?<br/>
http://smackerelofopinion.blogspot.co.uk/2009/10/dumping-acpi-tables-using-acpidump-and.html
cstate entries should be is SSDT.dat. so use iasl -d on it
</p>
<p>
The following patch was made (copied from x60 mainboard.c): <a href="future/donotusethis_macbook_acpi.diff">do not use this</a><br/>
(resulted in bricked macbook21: grub booted, but kernel would get stuck while booting (flashing text). wasn't sure how to debug)

</p>
<p class="lenovobios">
Following this guide means simply flashing a libreboot ROM. This guide will not (directly) teach you how to make a backup (dump) of the original Lenovo BIOS
because to do so would be to explicitly endorse proprietary software. However, for the purposes of reverse engineering it can be useful
to have a backup. Each copy of the original Lenovo BIOS is tied to the specific machine that it came from; it will not run
on any other machine, even if it's the same type of machine as yours. What this means is that, effectively, you can back it up now (so that you can
re-flash it later if you want to run the original Lenovo BIOS again) or lose it forever. The X60/T60 installation
guide on the coreboot wiki will show you how to do this:
<a href="http://www.coreboot.org/Board:lenovo/x60/Installation">http://www.coreboot.org/Board:lenovo/x60/Installation</a>.<br/>
Do not make this decision lightly! This is your last and only chance.
</p>
<p>
The following is for the libreboot image and *not* the factory bios dump:
</p>
<p>
Check the last two 64K regions in your ROM file (libreboot.rom in this example):<br/>
<b>$ dd if=libreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s libreboot.rom) - 0x10000] count=64k</b><br/>
<b>$ dd if=libreboot.rom of=lower64k.bin bs=1 skip=$[$(stat -c %s libreboot.rom) - 0x20000] count=64k</b><br/>
<b>$ sha512sum lower64k.bin top64k.bin</b><br/>
Make *sure* that they match before you continue. The ROM's included pre-compiled in libreboot should already match.
If they don't match, then do this (based on those instructions from <a href="http://www.coreboot.org/Board:lenovo/x60/Installation">coreboot wiki</a>):<br/>
<b>$ dd if=top64k.bin of=libreboot.rom bs=1 seek=$[$(stat -c %s libreboot.rom) - 0x20000] count=64k conv=notrunc</b><br/>
After this, the ROM will be safe to flash. Explanation is provided in <a href="#build_bucts">#build_bucts</a>.

<h1 id="grub_font">Setting font in GRUB (for reference)</h1>
<p>You don't need to do this unless you would like to change the default font yourself.
(this is just for reference. It has already been done for you)</p>
<p>The old font used was Unifont, and this had some missing characters: for instance, the border showed ??? characters instead of lines.</p>
<p>I tried DeJavu Sans Mono from this website:
<a href="http://dejavu-fonts.org/wiki/Download">dejavu-fonts.org</a></p>
<p>Specifically, the version that I chose was the latest at the time of writing (Saturday 21 June 2014):
<a href="http://sourceforge.net/projects/dejavu/files/dejavu/2.34/dejavu-fonts-ttf-2.34.tar.bz2">this one</a></p>
<p>This is a free font that is also contained in GNU/Linux distributions like Trisquel or Parabola.</p>
<p><b>$ cd libreboot_src/grub</b><br/>
compile grub ('build' script has the info on how to do this)<br/>
come back out into libreboot_src/resources/grub:<br/>
<b>$ cd ../libreboot_src/resources/grub/font</b></p>
<p>I took Dejavu Sans Mono from dejavu (included in this version of libreboot) and did:<br/>
<b>$ ../../../grub/grub-mkfont -o dejavusansmono.pf2 ../../../dejavu-fonts-ttf-2.34/ttf/DejaVuSansMono.ttf</b></p>
<p>I then added the instructions to 'build' script to include resources/grub/dejavusansmono.pf2 in all of the ROM's in root of cbfs.<br/>
I then added that instructions to the grub.cfg files (to load the font):<br/>
<b>loadfont (cbfsdisk)/dejavusansmono.pf2</b></p>

<h2 id="grub_custom_keyboard">Custom keyboard layout in GRUB (for reference)</h2>
<p>
Keymaps are stored in resources/utilities/grub-assemble/keymap/.
</p>
<p>
Example (French Azerty):<br/>
<b>$ ckbcomp fr > frazerty</b><br/><br/>
Go in grub directory:<br/>
<b>cat frazerty | ./grub/grub-mklayout -o frazerty.gkb</b>
</p>
<p>
You must make sure that the files are named keymap and keymap.gkb (where 'keymap' can be whatever you want).
</p>
<p>
Then from the above example, you would put <b>frazerty</b> in <b>resources/utilities/grub-assemble/keymap/original/</b> and
the <b>frazerty.gkb</b> file goes under <b>resources/utilities/grub-assemble/keymap/</b>
</p>
<p>
The scripts <b>build</b> and <b>buildrom-withgrub</b> will automatically see this, and automatically build
ROM's with your custom layout (given the name) and include them under bin. Example: <b>libreboot_frazerty.rom</b>.

<h2 id="howtouse_powertop">Powertop - how to use</h2>
<p>Now you can use this command to kill that noise:<br/>
<b>$ sudo powertop --auto-tune</b></p>
<p>You can also run it without parameters and then go into 'Tunables' and set everything to 'Good'</p>
<p>Note: On Trisquel 6, you will need to use a later powertop version from git. The one in the repositories is too old. See below:</p>
<h2 id="powertop_autostart">Powertop - Start automatically at boot time (Trisquel 6)</h2>
<p>Included with libreboot is a script called 'powertop.trisquel6'. Run this and it will setup powertop to run with --auto-tune
at boot time. Load the file in your text editor to see how it does that.</p>
<p><b>$ ./powertop.trisquel6</b></p>

<h1 id="high_pitch_parabola">High Pitched Whining Noise on Idle (how to remove in Parabola)</h1>
<p>The following removes most of the noise. It reduces what is a high frequency whine
(that not everyone can hear) to a slight buzz (which most people can't hear or doesn't bother most people).</p>
<p>This is not perfect! The full solution is still not discovered but this is a step towards that.
Also, in some instances you will need to run 'sudo powertop --auto-tune' again.
This needs to be implemented properly in coreboot itself!</p>
<p>On the X60 with coreboot or libreboot, there is a high pitched sound when idle.
So far we have use processor.max_cstate=2 or idle=halt in GRUB.
These consume power. Stop using them! </p>
<p>Be root<br/>
<b>$ su -</b></p>
<p>Installed powertop:<br/>
<b># pacman -S powertop</b></p>
<p>and added the following to /etc/systemd/system/powertop.service :</p>
<pre><i>
[Unit]
Description=Powertop tunings
[Service]
Type=oneshot
RemainAfterExit=no
ExecStart=/usr/bin/powertop --auto-tune
# "powertop --auto-tune" still needs a terminal for some reason. Possibly a bug?
Environment="TERM=xterm"
[Install]
WantedBy=multi-user.target
</i></pre>
<p>Finally, as root do that:<br/>
<b># systemctl enable powertop</b><br/>
<b># systemctl start powertop</b></p>
<p>The next time you boot the machine, the buzz will be gone.</p>

<h1 id="serial">X60/T60: Serial port - how to use (for dock owners)</h1>
<p>
For the Thinkpad X60 you can use the <b>"UltraBase X6"</b> dock (for the X60 Tablet it is called
X6 Tablet UltraBase). For the ThinkPad T60,
you can use the <b>"Advanced Mini Dock"</b>.
</p>
<p>
If you are using one of the ROM's with 'serial' in the name, then you have serial port enabled in libreboot
and you have memtest86+ included inside the ROM. Connect your null modem cable to the serial port on the dock
and connect the other end to a 2nd machine using your USB Serial adapter.
</p>
<p>
On the 2nd machine, you can try this (using GNU Screen):<br/>
<b>$ sudo screen /dev/ttyUSB0 115200</b>
</p>
<p>
How to quit GNU Screen: Ctrl+A then release and press K, and then press Y.
</p>
<p>There are also others like Minicom but I like GNU Screen</p>
<p>
By doing this before booting the X60/T60, you will see console output from libreboot. You will also see
GRUB displaying on the serial output, and you will be able to see MemTest86+ on the serial output aswell.
You can also configure your distro so that a terminal (TTY) is accessible from the serial console.
</p>
<p>
The following guide is for Ubuntu, and can be followed for Trisquel 6.0 which is based on Ubuntu 12.04
(should also work in Trisquel 7, based on Ubuntu 14.04) to enable a serial console using GeTTY:<br/>
<a href="https://help.ubuntu.com/community/SerialConsoleHowto" target="_blank">https://help.ubuntu.com/community/SerialConsoleHowto</a>
</p>
<p>
Note: part of the tutorial above requires changing your grub.cfg. Just change the <b>linux</b> line to add instructions for enabling getty.

If neither of these options work (or they are unavailable), physically removing the LCD panel is an option.
Usually, there will be information printed on the back.

Document everything listed in this discussion (and the link)
SeaVGABIOS+SeaBIOS support for X60/T60 (VBT is missing, see docs/future/index.html):
Read that: http://www.coreboot.org/pipermail/coreboot/2014-July/078342.html
This page talks about 'calibration' in powertop:
https://docs.fedoraproject.org/en-US/Fedora/15/html/Power_Management_Guide/PowerTOP.html
I should think about adapting information here based on that page.
Look into 'git archive' instead of deleting .git
eg (coreboot directory):
git archive --format=tar --prefix=libreboot/ -o ../libreboot_release.tar HEAD
