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.
|
||||
The MacBook1,1 and MacBook2,1 are very similar to the
|
||||
ThinkPad X60. It shares some hardware with the X60 such as the chipset.
|
||||
|
||||
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

believed that this is the only difference.

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.
|
||||
OSes using Linux on Apple EFI firmware
|
||||
======================================
|
||||
|
||||
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.
|
||||
You have 2 choices for booting up OSes using Linux as their kernel
|
||||
on the MacBook:
|
||||
|
||||
GNU+Linux on Apple EFI firmware
|
||||
===============================
|
||||
* Boot via USB ;
|
||||
|
||||
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.)
|
||||
* Boot via a CD or DVD.
|
||||
|
||||
Boot via a CD or DVD
|
||||
--------------------
|
||||
|
||||
The Apple EFI firmware contains a PC BIOS emulation layer for booting
|
||||
Microsoft Windows on CDs and DVDs. That emulation layer **only** works
|
||||
if booting from a CD/DVD or from the hard drive. The MacBook will **not**
|
||||
boot MBR bootloaders from USB, which is why booting from a CD or DVD is
|
||||
easier than booting from a USB.
|
||||
|
||||
* First, burn your ISO to a CD or DVD ;
|
||||
|
||||
* Reboot and while rebooting, hold down the Alt/Control key, a boot menu
|
||||
should pop up, requesting you to choose which device to boot from ;
|
||||
|
||||
* Select the CD/DVD icon with 'Windows' as the label (the Apple EFI firmware
|
||||
elways recognises CDs/DVDs using MBR as 'Windows', because the emulation
|
||||
layer was made specifically for booting Microsoft Windows as part of
|
||||
BootCamp, a tool which allowed dual-booting Windows and OS X) ;
|
||||
|
||||
* Install it like you normally would (If there's an OS X installation then
|
||||
it's highly recommended to save all your data and wipe it. Libreboot isn't
|
||||
able and will never be able to boot OS X) ;
|
||||
|
||||
* While rebooting, hold Alt/Control once again, and select the hard disk
|
||||
icon with the 'Windows' label, after each subsequent boot, the Apple EFI
|
||||
should boot up properly automatically.
|
||||
|
||||
*If you installed your OS alongside OS X then you won't be able to boot
|
||||
to it using GRUB, despite the fact that it does sometimes show up. You
|
||||
also won't be able to boot it up when using Libreboot.*
|
||||
|
||||
Boot via USB
|
||||
------------
|
||||
|
||||
This method is harder than booting from a CD/DVD and may soft-brick your
|
||||
MacBook but it's the only way to boot up successfully from a USB.
|
||||
|
||||
The PC BIOS emulation layer found in the Apple EFI firmware doesn't work
|
||||
when booting up from a USB stick. Despite the fact that the
|
||||
MacBook2,1 does use a 64-Bit processor, the firmware only supports booting
|
||||
32-Bit EFI devices, meaning you're stuck with 32-Bit OSes and rare
|
||||
64-Bit OSes which have ISOs that still support booting from 32-Bit EFI.
|
||||
Meanwhile, GRUB fully supports booting up 64-Bit OSes on 32-Bit EFI.
|
||||
|
||||
* First, search for an ISO that supports 32-Bit EFI while being 64-Bit or
|
||||
a normal 32-Bit ISO and put it in your USB stick ;
|
||||
|
||||
* Reboot and while rebooting, hold down the Alt/Control key, a boot menu
|
||||
should pop up, requesting you to choose which device to boot from ;
|
||||
|
||||
* Select the USB icon ;
|
||||
|
||||
* Install it like you normally would (If there's an OS X installation then
|
||||
it's highly recommended to save all your data and wipe it. Libreboot isn't
|
||||
able and will never be able to boot OS X) ;
|
||||
|
||||
* Reboot. It should boot up to your newly-installed system if you wiped OS X,
|
||||
else, hold Alt/Control and select the correct boot device ;
|
||||
|
||||
* Flash Libreboot. DO NOT REBOOT AGAIN BEFORE FLASHING. Sometimes the
|
||||
firmware can get confused, because Apple never intended to boot other
|
||||
EFI OSes other than OS X, as such there's a chance that your MacBook can
|
||||
become [soft-bricked](https://apple.stackexchange.com/questions/408104/late-2006-macbook-doesnt-turn-on-fan-spinning-but-no-chime/409754).
|
||||
If that is the case then dissassemble it and remove
|
||||
the CMOS/PRAM battery, wait a few minutes, and put it back in.
|
||||
|
||||
*If you want to install Libreboot with the SeaBIOS payload then be sure
|
||||
to reconfigure GRUB2 correctly, else your system won't boot.*
