Cedar Trail Update

Please note: These instructions only apply to ubermix 0.9x. ubermix 1.x already has Cedar Trail support built-in. See Cedar Trail Devices for details.

If you have an existing ubermix v0.9x image that you would like to add Intel Atom N2x00 (Cedar Trail) compatibility to it without having to completely reinstall and reconfigure, you can do the following to forward-port your image:

First, install a clean version of your image from your already customized USB key. Next, if you are running a version of ubermix prior to v0.913 and have not already done so, increase the size of your base system partition, according to the instructions under Resizing the Base System Partition on the Customization page on the ubermix.org site. Quick steps are:

1. Boot your machine from an ubermix USB key
2. Select option 5, "Expert Options" at the main menu
3. Select option 3, "Resize the base..." from the Expert menu
4. Enter the size you want - I would suggest 5Gb, since we only need a little bit of space.
5. Reboot when done

Once your netbook is imaged and ready, connect it to the Internet and download the following 4 packages using Firefox or Chrome:

• linux-image-3.3.0-22-generic_915_i386.deb
• linux-headers-3.3.0-22-generic_915_i386.deb
• xf86-video-modesetting_0.2.0-1_i386.deb
• lxrandr_0.1.1-4ubuntu1_i386.deb

Now, shutdown your netbook and follow these steps:

1. Boot your machine, and press "esc" when the screen goes blank immediately after showing the model specific splash screen.
2. Select "Normal Boot" and press the "e" key on your keyboard
3. Select the line in the box that begins with the word "initrd" and move the cursor to the end of the line. Backspace over the four letters "aufs" and replace them with "generic". Do not add any spaces.
4. Press "ctrl-x" to boot your machine
5. When your machine finishes booting up, open a terminal (ctrl-alt-t) and type the following: sudo dpkg -i Downloads/*.deb
6. Reboot

When your machine boots back up, make sure that everything is working and delete the 4 files you downloaded above from the downloads folder. Then proceed to update the image on your custom USB key, if you plan to install on additional Cedar Trail netbooks.
