Hi, I'm wondering if anyone will be able to help me with a problem I've found.

I flashed my Acer C720 some time ago and it has been working beautifully running Ubuntu 14.04. I now want to boot from USB to make some changes to my install, but I find I'm not able to.

When I press "ESC", I can see the USB key in the boot menu, but when I select it I'm booted into Jeltka and asked for login credentials.

The USB key works in other PCs without an issue.

Any ideas?

I tried various ways of creating the USB key and only had reliable success using Win32diskimager from within Windows.

Setup several celeron asus chromeboxes and decided to try my hand at an i3. All went ok until tried to hit 'ESC' to see the USB, but SeaBios didn't pick up on the ESC press. So... I got the same flashrom as I had for the celerons and flashed the system (flashrom -w -i RW_LEGACY:asus-chromebox-SeaBIOS-new.bin). Now, it looks like it's bricked. Is it? No matter what's done, the system stays on the white OS verification screen. 

What can be done to rectify without having to get a bus pirate?
Thanks!

+David S if you want to actually make use of the legacy boot feature, then you need to update the SeaBIOS payload since the stock one is non-functional (it's the same on both the celeron and i3/i7 models).

I already got ChromeOS off my Acer #C720 and I'd like to install the John Lewis firmware.
What steps are necessary? Opening the screw? Exactly the same steps as described on JLs Homepage?
I'm missing the big picture.

Or should I say, download and run the script again - you won't get an updated ROM unless you download an updated script!

I do like this article. If you were being cynical, you might conclude that they were using the "free" angle to help publicise the project, whilst gradually climbing down from their original "bold" (read: BS) claims. "Purism" it ain't ...
 
Purism certainly was backtracking on the firmware side.
; Purism Librem is an interesting project which promises to produce a completely libre laptop, designed to respect the user's privacy and the user's rights. The indivduals behind the project seem so confident as to "promise that a Purism system and all its components will be free according to

Yep. It's certainly the freeest option at the moment, although IIRC you need a small binary blob for graphics in the firmware. Thing is, it will be slow, and Linux ARM support is still not on a par with x86, so you can't use it for as much stuff as an x86 Chromebook.

Does anyone know if flashing a rom with the short delay dev screen flag set - if that will effect the chromebook recovery utility? basically...

open shell
sudo -s
cd /usr/local/
flashrom -r bios.bin
gbb_utility --set --flags=0x01 bios.bin newbios.bin
flashrom -w newbios.bin
(insert recovery usb and attempt to recover)
unknown error after verification of image.

It ended up being the image I was using for the flash drive. I grabbed a new version, and it's recovering. Thanks for the help.

The new Acer chromebooks (c740 and c910) won't have baytrail processors, but they will still have the same issues with seabios since they have emmc, right?

Forgive me if I've over looked it, but I can't seem to find it anywhere. Is there a way to change the time out of the Seabios boot? Right now it takes about 4-6 seconds to then boot grub and I was just wondering if there was a way to shorten that to 1 second.

Hi all! Sorry to bother, I'm a Linux noob and struggling with the installation of this OS on a HP Chromebook 14 (Falco) which I bought for the specific purpose of running it.

I successfully installed Coreboot Lewis firmware (thanks to your script, really appreciated!), I'm able to enter the boot menu through the Esc key (what a funny design.. we can't hold it or even press it to early, and from a non-developer POV I wonder why :) but coreboot doesn't recognize any of my USB key/drives: I tried 4 in total, and to be sure I also use an external powered drive (that one gets recognized actually but won't boot).

Battery has already been disconnected and reconnected.

I'm pretty frustrated cause all those keys/drives (dd was used) have successfully been tested and able to boot on another PC Laptop and even on a MacBook pro (I believed the chromebook to be more penguin-friendly).

Now I'm thinking that I'm doing something really wrong, or to be in possess of a faulty unit (can't test on Chrome os cause I wiped the original firmware but I remember that those drives could mount properly). Could coreboot be that picky about USB peripherals?!?

Any suggestion is welcome! many thanks :)

I think it's usb bus problem.. hope I can put original bios firmware back in place for a warranty claim.. none of those drives could be seen by coreboot. Images format is not making a difference at this stage (anyway I went back to dd just the iso without converting, thanks for the tip! I was just following a probably too old online tutorial).

For those that are interested in coreboot and Chromebook firmware, the recently relesed Embedded Firmware Solutions book has a couple of chapters on the topic.

I have a question before I flash; how would I restore C720P to stock after I have removed the screw and flashed the ROM?

Hi John!

I am having some issues with my Chromebook - I flashed onto your Seabios build not to long ago and in the end I wanted to go back to the old version of my bios but I stupidly lost the recovery USB so I used your guide to extra the bios from an image and I reflashed this (It's the X86 FALCO TEST 0289 ones) and now I am back up and running on ChromeOS but I am unable to update past 39.0.2171.96 which is super frustrating! I have tried reinstalling ChromeOS but to no avail it is still on 39.0.2171.96.

Any ideas on what I can/should be looking at doing to fix this problem?

Did anyone have problems flashing the ROM chip on their Acer C720?

Tried typing in "set_gbb_flags.sh 0×489" and it came back with "command not found"

Ref articles:
http://johnlewis.ie/how-to-make-seabios-the-default-on-your-acer-c720/

http://blogs.fsfe.org/the_unconventional/2014/04/20/c720-debian/
Divulged this evening by Duncan Laurie on the coreboot mailing list: If you want to boot SeaBIOS by default and you have unlocked the SPI flash write protection you can set flags in the (write protected) “GBB” flash region that will make it boot legacy mode by default.

Just flashed my Samsung Chromebox 3 aka Stumpy I/O edition with coreboot-stumpy-seabios-181214.rom from stock and it gave a warning stating:

*This ROM has bricked one Stumpy, although it has worked succesfully on at least one other. Continue at your peril. Please report success to the G+ community or CTRL-C out if you´re not okay with being a guinea pig.*

Therefore this is me reporting my succes to the G+ community. board-status.run reported that everything was up to date, and I am typing this from Ubuntu 14.10 on the Chromebox. Anything else I need to test/check?

Well, I'm thankful that you did. I wonder what happened with the one or two bricks. Perhaps they had a slightly different board rev, or it's "user" error.

John,

Firstly, many thanks for your efforts in producing your ROMs.

I have an Acer C720 that had a bad flash and was bricked. Using your ROM (181214), a raspberry pi and a Pomona clip I was enable to restore Seabios.

The problem is my keyboard only seems to be partially working. Some keys work while others have no effect at all. I eventually figured out what was happening and used a USB keyboard to acres the boot menu and install Ubuntu.

Thinking that it might be something to do with the flash I have since reflashed using your script successfully but the problem persists. Only certain keys are recognised and it's really frustrating...

I've scoured your blog to see if it has happened to anybody else but can't seem to find another instance of this. Any idea what might be going on?

Regards,

Daniel.

Hi John...Thanks for all the knowledgeable input.
I'm using a ACER C710-842G32ll. I wanted to run Windows7 natively.
I've followed the guide by Johnny. Flashed the ROM by using the script stated in your website..."cd; rm -f getnflash_johnlewis_rom.sh; curl -k -L -O https://johnlewis.ie/getnflash_johnlewis_rom.sh; sudo bash getnflash_johnlewis_rom.sh". Boot Windows7 installer from USB.
But instead got a BSOD that says "The BIOS in this system is not fully ACPI compliant"

Did I flashed the wrong ROM? Please help....I'm pretty much a noob :D
Thx!

Kernel 3.19 working nicely here on my C720, at least on Arch Linux (testing repo) CONFIG_ATH9K_PCOEM is enabled so wifi works.
I recommend anyone who avoided the 3.19 RCs to bump to this stable release as it fix the GPU hangs.
