ENSURE YOU TAKE HEED OF THIS STICKY POST AND THE COMMUNITY RULES (TO THE RIGHT) BEFORE POSTING.  

IF ANYONE HAS A BAYTRAIL CHROMEBOOK WHICH ISN'T COVERED BY THE SCRIPT, COULD THEY PLEASE POST THE MODEL NAME (FROM THE SCARY DEV BOOT SCREEN), AND I'LL GET IT ADDED ASAP. PLEASE NOTE - BOOTING DIRECT FROM THE eMMC DOES NOT YET WORK, AND SOUND DOES NOT ALSO WORK OOTB.

I'M CURRENTLY OUT OF THE COUNTRY WITHOUT MY BITS, SO FOR THE NEXT FEW MONTHS I WILL NOT BE ABLE TO TEST ANY BUILDS.

I AM NOT HERE TO TEACH PEOPLE LINUX FUNDAMENTALS. IF YOU DON'T HAVE A REASONABLE IDEA OF HOW TO USE THE LINUX COMMAND LINE, DON'T ASK ADVANCED QUESTIONS, OR AT LEAST COMPLETE THE LINUX FOUNDATION'S FREE "INTRO TO LINUX" COURSE @ https://www.edx.org/course/introduction-linux-linuxfoundationx-lfs101x-2#.VN3jAlWsXWU BEFORE YOU POST.

It"s all pretty much in the Arch wiki (plus a lot besides). I've already brought it back from the dead for someone in the EFF, I'm not about to do it again.

+CoolStar Organization What are your plans for releasing firmware and trackpad driver? I have correctly screwed up my Linux Mint system and I don't want to waste extra time on setting it up again.

Would I be correct in thinking that there'd be a smooth transition from booting from GRUB on a USB/SD card to booting from SeaBIOS once eMMC support for it is available for Bay Trail devices, such as my Swanky Toshiba CB2?

Just make sure, if it asks you where Grub is going to be installed, to choose /dev/sda instead of /dev/mmcblk0

HELP!! I reflashed John Lewis Rom on my Acer C720 because I was having issues installing Chromium OS from USB. I chose option 4 this time with completely flashes a new BIOS. It didn't give me any errors during the flash so I rebooted and it came back to Chrome OS. My it didn't want to shut down so I hit Power + Refresh keys which normally rebooted in the past. Now it shut down and won't turn back on. If I hit the power button nothing happens. If I press Power + Refresh or Power + F2 the power light lights up for a second but thats it. Please help!

May not be the same issue but give it a go..

Ok, looks like the coreboot-related modifications I was planning to do are near complete (I'll probably only modify the DSDT) however sleep doesn't work. +John Lewis , mind sharing the sleep fix you used on your Falco/Peppy ROM's?

Does anyone know how to disable hardware write protection on Toshiba Chromebook 2??

You have to open up the chromebook, there are 2 more screws hidden. Then on very bottom right of the heatsink you will spot the write protect screw. It's shortened with a screw, the heatsink itself and a little metal sticker that you have to peel off after removing the heatsink. Either isolate it then or clip off the bit of the heatsink touching the contacts.

I'd just like to take the opportunity here to thank the open source ReactOS and DragonFlyBSD projects.

(I used driver code from DragonFlyBSD instead of Linux as I found it easier to read.)

Without being able to use their code as reference I wouldn't be able to make such swift progress in getting Windows running on my chromebook :)

C200 baytrail chromebook disassembly
I removed the upper left screw to apply John amazing rom. Before proceeding, Is there a way check if write protection is actually disabled or if I need to remove another screw?

As I said, i'm not a Linux expert. But i've read that the latest alsa driver were now integrated to the kernel. So i tried unsucessfully to update to the latest unstable kernel. Now i guess the next step is to find that "alsa.conf", understading were i have to put the custom file you mentionned, and identify in my chromebook model source what to add in it... Am i right ?

Any ideas how to install Chromium OS with one of John Lewis's SeaBios ROMS?  I'm  opening a terminal and logging in as chronos, but when I run the command: /usr/sbin/chromeos-install, it says it doesn't recognize the location of the dev/sdb1 drive. I want to keep Chrome OS on my Acer C720, but I installed John Lewis's ROM so I can potentially dual boot Ubuntu or Windows later on.

+Timothy Li +John Lewis +Matt DeVillier I got it to work using a different USB flash drive! Kind of weird because the one I was originally using is a SanDisk Cruzer Glide, and the one that worked is some generic brand, so in this case the cheaper flash drive worked better, although I've seen it work the other way around too. Thanks guys so much for your help! By the way +Timothy Li  it was your method that worked, but the other suggestions probably would have worked as well had I tried them with this different flash drive. Thanks again!

This is especially for +Nicolas Lhommet.
You'll need git, gcc, ncurses-devel, iasl and possibly other tools installed. Presumably from your home directory, run: git clone https://chromium.googlesource.com/chromiumos/third_party/seabios -b chromeos-2014.11.03 chromeos-seabios. to download the latest ChromeOS SeaBIOS sources.

Good work on at least getting Coreboot to work reasonably on a Bay Trail chromebook, that's more than good enough for me! one question, though, would one be able to install to an external SD card (I know the internel eMMC is inaccessible to SeaBIOS at current)? otherwise, I could always spare another USB stick, I have tons

Hey all,

I've got an Asus c300 that I've just ran the script on.  When it boots up it loads seabios just fine, but doesn't detect any bootable devices.  Any ideas?

Thanks in advance!

Just reporting back--Arch is installed and working great!  I can't tell you how happy I am to finally have a native linux install on my c300!

+Matt DeVillier and +John Lewis , thank you both SO much! :D

I've removed the write-protect screw from my Acer C720 and flashed +John Lewis SeaBios. Now that I've flashed the bios, is it possible to reenable write-protect without messing up the SeaBios install? The reason I'd like to try this is because I've installed Chromium OS and upgraded it to Chrome OS, but every time I boot into Chrome OS it gives me a hardware ID malfunction error and it also won't allow updating. I wondered it perhaps the write-protect screw being removed was the cause of this and if putting the screw back in would fix the problem without messing up the SeaBios installation?

+John Hill The Chromium OS USB is reusable as many times as you like. It does not change (or lose some of its magic) just because you have used it to install Chromium OS on a HDD. By the way, both "install /dev/sda" under crosh, and "sudo /usr/sbin/chromeos-install --dst /dev/sda" under shell work. I just tried using the latest arnoldthebat build http://chromium.arnoldthebat.co.uk/daily/Camd64OS-20150702010101.img.7z

[Asus C300m - baytrail device]

Hi all,

I've been following this page for some time now as I have this asus c300m which I would like to convert to a linux system. Today I decided to take the plunge. I hoped that Hervé's picture of his C200 would help me out locating the write-protect screw but apparently they have a different mainboard layout.
So, I think it is the one at which the red arrow is pointing, but I'm absolutely not sure. Google ain't helping out either.

+John Lewis Yeah you're right. I guess this time I was a bit too nonchalant. 

Well anyway, unless It does fall under warranty, I guess my hack-a-chromebook-adventure has ended here. Thanks for the help and good luck with further development of your custom roms.

Well thanks to you all, my C200 has now a fully working Linux Mint XFCE installation. sound working like a charm after copying the files given in that post, and activating "Right speaker mixer right dac" and "left speaker mixer left dac" in AlsaMixer. I learned how to manage with grub2, and its custom menu entries to boot on a small usb key (an old 256Mo) ... Thank you guys for helping

So yeah, I'm a girl, a natural blonde and also a geek who LOVES to tinker... so I know the jokes are soon to ensue. :)  Bottom line... I've borked my c270 as I tried to install a new distro (Haze OS https://www.distroshare.com/distros/get/73/) and it appears the live OS committed changes to the partition before I agreed to them. SOOO... now, when rebooting, I'm stuck at the black SeaBIOS screen without any option (ignoring my key strikes) and insists on booting from the hard drive... now, I've got the tune, "Help me, Rhonda... help help me Rhonda". in my head... :) :)

PS - I said coreboot specific because I think some how I've screwed up +John Lewis' ROM....
Haze OS is a highly customizable, easy-to-use and a free Linux based Operating System. It’s based on Debian testing and other modern Linux desktop technologies to keep you updated with the most recent and best software till date and not requiring to upgrade/reinstall this OS ever again.
