Before being merged with the commitdc6e1f32c1("Import website-build to build the GNU Boot website."), website-build was a separate git repository. And so, even after the merge, until the commit20d122e94a("website-build: use website from local git repository."), it still worked in the same way and still downloaded the website from git. This prevented merging the website and website-build directories together as the GNU Boot repository also needed to be a valid Untitled website repository as well. Now after this commit, the website is built from the same git tree, so we can simply adjust the build scripts to be able to move things around. In addition of making things more clear for contributors, it also simplify the migration to haunt as with haunt we typically have the haunt.cfg (and the autotools build code if needed) code in the top directory and the markdown files in a subdirectory.

title: MacBook2,1 and MacBook1,1
|
|
x-unreviewed: true
|
|
...
|
|
|
|
There is an Apple laptop called the macbook1,1 from 2006 which uses the
|
|
same i945 chipset as the ThinkPad X60/T60. A developer (Mono Moosbart) ported
|
|
the Macbook2,1 to coreboot, working alongside Vladimir Serbinenko. The ROM
|
|
images also work on the macbook1,1. Libreboot's support and documentation for
|
|
this is based on the Libreboot project, which also supports macbook2,1
|
|
|
|
Some macbook2,1 models are late 2006, others are early 2007.
|
|
You do not need to use external flashing equipment when flashing the MacBook2,1
|
|
but the MacBook1,1 requires external flashing equipment while running Apple EFI
|
|
firmware.
|
|
|
|
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.
|
|
|
|

|
Internal flashing
|
|
=================
|
|
|
|
Macbook2,1 can always be flashed internally, even if running Apple firmware:
|
|
|
|
sudo flashrom -p internal:laptop=force_I_want_a_brick,boardmismatch=force -w your.rom
|
|
|
|
Macbook1,1 same as above, but if running Apple firmware see below for
|
|
external flashing.
|
|
|
|
External flashing
|
|
=================
|
|
|
|
macbook1,1 requires external flashing, if running the default Apple firmware.
|
|
macbook2,1 can be flased internally, regardless.
|
|
If running coreboot, libreboot or Libreboot, you can already internally re-flash.
|
|
|
|
[This page shows disassembly
|
|
guides](https://www.ifixit.com/Device/MacBook_Core_2_Duo)
|
|
|
|
Locate the flash. It'll be a SOIC8, which looks like this:
|
|
|
|
|
|
|
|
motherboard. [How to remove the
|
|
motherboard](https://www.ifixit.com/Guide/MacBook+Core+2+Duo+PRAM+Battery+Replacement/529).
|
|
|
|
Refer to the following guide:\
|
|
[Externally rewrite 25xx NOR flash via SPI protocol](../install/spi.md)
|
|
|
|
You need to replace OS X with GNU+Linux before flashing Libreboot. (OSX
|
|
won't run at all in Libreboot), if you wish to internally flash on a macbook21.
|
|
Libreboot won't boot OSX either (well, maybe with Tianocore it would, but that's
|
|
untested and OSX is inferior to GNU+Linux). In general you should think of
|
|
your Macbook like a regular laptop, for the purposes of anything coreboot.
|
|
|
|
If it's a macbook2,1 with the core2duo processors, you can run
|
|
a 64-bit distro. For macbook 1,1 the CPU probably only has 32-bit support.
|
|
|
|
GNU+Linux on Apple EFI firmware
|
|
===============================
|
|
|
|
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.)
|
|
|
|
Coreboot wiki page
|
|
==================
|
|
|
|
The following page has some information:
|
|
|
|
* <https://www.coreboot.org/Board:apple/macbook21>
|
|
|
|
Issues and solutions/workarounds
|
|
================================
|
|
|
|
There is one mouse button only, however multiple finger tapping
|
|
works. Battery life is poor compared to X60/T60. The Apple logo on the
|
|
back is a hole, exposing the backlight, which means that it glows. You
|
|
should [cover it up](http://cweiske.de/tagebuch/tuxbook.htm).
|
|
The MacBook2,1 consumes more power with libreboot than with the Apple EFI firmware, which means it overheats a lot.
|
|
|
|
*The MacBook2,1 comes with a webcam which does not work with free
|
|
software. Webcams are a privacy and security risk; cover it up! Or
|
|
remove it.*
|
|
|
|
Make it overheat less
|
|
---------------------
|
|
|
|
*This section is less relevant for Libreboot 20211122 and newer, because cstate
|
|
level 3 support was added, thanks to vitali64 on IRC. This means that the CPU
|
|
temperature is much lower most of the time, as is power consumption. However,
|
|
you might still benefit from the steps below, just not as much as you would have
|
|
previously benefited.*
|
|
|
|
The MacBook2,1 overheats a lot with libreboot, we still don't know why but a simple workaround is to install macfanctld.
|
|
|
|
Macfanctld is available on the default repos of many distributions.
|
|
|
|
For example, to install macfanctld on an Arch-based distro (Parabola, ...), you would run as root
|
|
|
|
pacman -S macfanctld
|
|
|
|
and don't forget to enable it by using `systemctl` or by a script that will run macfanctld if using runit.
|
|
|
|
Then, you want to install powertop and tlp.
|
|
And then, run the following on battery
|
|
|
|
sudo tlp start && sudo powertop --calibrate
|
|
|
|
Then, after quitting powertop, run :
|
|
|
|
sudo powertop --auto-tune
|
|
|
|
Now, configure tlp, edit the `/etc/tlp.conf` and uncomment/add/modify the following:
|
|
|
|
CPU_BOOST_ON_AC=1
|
|
CPU_BOOST_ON_BAT=0
|
|
|
|
SCHED_POWERSAVE_ON_AC=0
|
|
SCHED_POWERSAVE_ON_BAT=1
|
|
|
|
PLATFORM_PROFILE_ON_AC=performance
|
|
PLATFORM_PROFILE_ON_BAT=low-power
|
|
|
|
The MacBook will still overheat, just less.
|
|
|
|
Enable AltGr
|
|
------------
|
|
|
|
The keyboard has a keypad enter instead of an AltGr. The first key on
|
|
the right side of the spacebar is the Apple "command" key. On its
|
|
right is the keypad enter. We can make it act as an AltGr.
|
|
|
|
If your operating system is Trisquel or other dpkg-based distribution,
|
|
there is an easy solution. Under root (or sudo) run
|
|
|
|
dpkg-reconfigure keyboard-configuration
|
|
|
|
and select the option "apple laptop", leave other settings as their
|
|
defaults until you are given the option "Use Keypad Enter as
|
|
AltGr". Select this. The keypad enter key will then act as an AltGr
|
|
everywhere.
|
|
|
|
|
|
For Parabola or other systemd-based distributions you can enable AltGr
|
|
manually. Simply add the line
|
|
|
|
KEYMAP_TOGGLE=lv3:enter_switch
|
|
|
|
to the file /etc/vconsole.conf and then restart the computer.
|
|
|
|
Enable 3-finger tap
|
|
-------------------
|
|
|
|
A user submitted a utility to enable 3-finger tap on this laptop. It's
|
|
available at *resources/utils/macbook21-three-finger-tap* in the
|
|
Libreboot git repository.
|
|
|
|
Make touchpad more responsive
|
|
-----------------------------
|
|
|
|
Linux kernels of version 3.15 or lower might make the touchpad
|
|
extremely sluggish. A user reported that they could get better
|
|
response from the touchpad with the following in their xorg.conf:
|
|
|
|
Section "InputClass"
|
|
Identifier "Synaptics Touchpad"
|
|
Driver "synaptics"
|
|
MatchIsTouchpad "on"
|
|
MatchDevicePath "/dev/input/event*"
|
|
Driver "synaptics"
|
|
The next two values determine how much pressure one needs
|
|
for tapping, moving the cursor and other events.
|
|
Option "FingerLow" "10"
|
|
Option "FingerHigh" "15"
|
|
Do not emulate mouse buttons in the touchpad corners.
|
|
Option "RTCornerButton" "0"
|
|
Option "RBCornerButton" "0"
|
|
Option "LTCornerButton" "0"
|
|
Option "LBCornerButton" "0"
|
|
One finger tap = left-click
|
|
Option "TapButton1" "1"
|
|
Two fingers tap = right-click
|
|
Option "TapButton2" "3"
|
|
Three fingers tap = middle-mouse
|
|
Option "TapButton3" "2"
|
|
Try to not count the palm of the hand landing on the touchpad
|
|
as a tap. Not sure if helps.
|
|
Option "PalmDetect" "1"
|
|
The following modifies how long and how fast scrolling continues
|
|
after lifting the finger when scrolling
|
|
Option "CoastingSpeed" "20"
|
|
Option "CoastingFriction" "200"
|
|
Smaller number means that the finger has to travel less distance
|
|
for it to count as cursor movement. Larger number prevents cursor
|
|
shaking.
|
|
Option "HorizHysteresis" "10"
|
|
Option "VertHysteresis" "10"
|
|
Prevent two-finger scrolling. Very jerky movement
|
|
Option "HorizTwoFingerScroll" "0"
|
|
Option "VertTwoFingerScroll" "0"
|
|
Use edge scrolling
|
|
Option "HorizEdgeScroll" "1"
|
|
Option "VertEdgeScroll" "1"
|
|
