The above instructions tell you how to run any arbitrary Linux program, and with root access you should be able to do pretty much anything you want. Install your own build of Chromium OS First, download the recovery kernel, as explained above. Once you have the recovery kernel and the OS image, you'll stitch them together, copy them to a USB drive, and then boot your system from the USB drive.
Combine the recovery kernel and your OS image, to create a recovery image. This image will have the officially-signed Recovery Kernel so you can boot from USB and will install a self-signed SSD image so you can boot only with developer mode.
This disk will be completely erased, so make sure it doesn't have anything important on it. When the cros flash command finishes, you can simply unplug your USB key and it's ready to boot from. Make sure there is nothing important on your USB disk before you run this command. To install your recovery image, do the following:. Turn your Chrome OS Notebook off. Turn it back on. During the boot warning, press space to enter recovery mode. Wait until prompted to put your USB disk in.
Put the USB disk in. Wait while the image is copied to the SSD. If you reboot now, you'll be booting from your image you may need to wait past the recovery screen.
Since your image was not signed by the release keys it's self-signed image , it will only boot in Developer Mode. Components Here is a rundown of the parts that are not soldered down: Power supply: If you just want to see what the inside looks like, gaze upon this click for a high res version : However, we acknowledge that some people like to tinker. So here's a quick guide to taking it apart: Shut the system down and close the lid Flip the laptop over so the bottom is facing up Pop out the battery using the release switch in the middle of the case Remove the visible screws There should be 10 in total a line of 3 black, a line of 3 silver, and a line of 4 silver The black screws are M2x2x0.
Subpages 1 : How to boot Ubuntu on a Cr Douglas Anderson, Dec 8, , PM. Entering Developer Mode You might want to enter developer mode if you're following the instructions in the Chromium OS Developer Guide , or if you just want to get access to a shell on your device to poke around. The first time a Chrome Notebook boots in Developer Mode after leaving Normal Mode it will: Show a scary warning that its software cannot be trusted, since verified boot is disabled press Ctrl-D or wait 30 seconds to dismiss.
Entering Developer mode is easy: Remove the battery. Getting the recovery kernel If you are trying to install your own disk image onto your Cr Chrome Notebook maybe you're following the Chromium OS Developer Instructions , you need the recovery kernel. Leaving Developer Mode Returning to normal mode is as simple as entering developer mode: shut down, remove the battery, flip the switch, reboot. There are a couple of things to note, however.
First, assuming you haven't modified anything, the first time you boot in normal mode after leaving developer mode, the stateful partition will be erased. This is a much faster erase process than when entering developer mode, usually only 30 or 40 seconds, and only happens with the first boot. Second, verified boot will be enabled, meaning that only Google-signed images will be bootable. If you haven't modified the original kernel or rootfs partitions in any way, you should have no problems.
If you've made changes to the kernel partitions, the Cr will refuse to boot that kernel and will display a recovery screen.
You'll have to create a recovery USB drive to restore your Cr to the factory condition. This happens because the kernel verifies the rootfs as each block is read from the SSD, so it may not encounter a modified block until sometime later.
When it does, it will reboot immediately. As we expected, right-clicking doesn't do anything. To finish the review, we had to plug-in an external mouse. The There are very few ports on the device.
On the left is a VGA port. As stated above, storage devices and memory cards work for uploading files to the cloud, but do nothing else. We were able to attach both a wired and a wireless mouse to the USB port and both worked pretty well.
When it came to logging in, we noticed two interesting flaws. First, the system did not recognize any Google account we used with a username that did not end in gmail. When we tried to login with our laptopmag. From hitting the power button to reaching the login prompt was about 15 seconds.
However, then you must select your user account it shows you a list of profiles and enter your password or click guest and wait a few more seconds for everything to appear.
All told, with typing and clicking, this process takes about another 10 seconds for a total of 25 seconds. The latest MacBook Airs let you start working in 15 seconds. All you see is the Chrome browser, which opens with a list of your installed web apps and Chrome extensions and two menus that list Most visited and Recently closed sites.
In the upper right corner of the screen sit the system clock, wireless bars, and a battery indicator. If you have your Cr configured to allow multiple languages, a menu for choosing the input language appears between the clock and the wireless bar status.
While you are in one browser window there is no indicator to let you know that other windows exist. Even when you change windows, you are simply shuffled off to the next window, rather than given a menu that shows you how many windows are open and what they contain. The best example of a mini window like this is Google Talk, which can float around the bottom of the screen while you visit other web sites in the main window.
Another example we encountered is the player window from Napster. Google needs to do a much better job of handling these mini windows as it updates Chrome OS. Chrome OS offers very few configuration options right now for the Cr Nor can you control the power settings.
By clicking on the clock, you can change the time and date. The System section allows you to change the time, touchpad sensitivity and language.
