Okay, so, why would you want to do this? Well, in a nutshell, so your Chromebook pretty much behaves like a normal laptop i.e. no secure boot, will boot from any USB key, no more signing kernels and dd’ing them to obscure partitions, etc, etc. Before you start: It’s important to note this comes without any warranty, express or implied. If something goes wrong you will end up with a bricked Chromebook. If that happens you can purchase a Bus Pirate, Bus Pirate probe cable, and Pomona 5250 SOIC clip and get unbricking, as per my previous post. This will also make ChromeOS unbootable, so if you want to use ChromeOS at all, then don’t do this. The impatient and ill-resourced among you can scroll to the end for instructions on how to download and flash my Coreboot build, which again comes without any warranty and could bring hell and damnation upon your souls. There is now a patch which allows all 4 GB of RAM to be recognised, but it takes 5 seconds to reach the SeaBIOS prompt on a cold boot.
