Overview

A good place to start is the Chromium site. They have guides howto set your Chromebook into developer-mode and disassembly guides for almost all Chormebooks.

Both things will be nessary, if you want to flash your own version of Coreboot onto your Chromebook. It is nessary to close a circuit on the motherboard via either a jumper or a srew disable the write-protection of the spi chip. And to use the flashing tool flashrom in ChromeOs, you have to be in the developer-mode. If you already installed a Gnu/Linux-system or likely you can also use the flashrom from there (but then you would be in developer-mode any way).

Note: The first three Chromebooks are not supported by coreboot (and flashrom!?) at the moment. Namely

Release date Manufacturer Model Project code name
December 2010 Google Cr-48 Mario
June 2011 Samsung Series 5 Chromebook Alex
July 2011 Acer AC700 Chromebook ZGB

They are running Insyde H20
