How to backup and restore your AC100
There is number of options available, but generally Ubuntu Oneiric Ocelot is what you are looking for.
GET UBUNTU 11.10 NOW!
Ubuntu is definitely the easiest way to get Linux onto a AC100. However - if you are a Linux-User with more experience - or - if you want to learn more about how Linux works - then Gentoo might be an interesting alternative. All software is compiled during installation (interesting for all NON-X86 architectures) and therefore the assortment of software is bigger and your are not dependent on the choice the distribution made for you. Another advantage of Gentoo is shurely the possibility to get the smallest Linux running (light-weight) which fits exactly to your demands. But WARNING: This stuff is not for Linux-Newbies!
- Download boot-installer-2.6.37-1-ac100.img.
- Start AC100 into developer mode (CTRL + ESC + POWER).
- nvflash -r –download 6 boot-installer-2.6.37-1-ac100.img
- Download ubuntu-natty-netbook-2.6.37-1-ac100-rootfs.tgz to a usb stick and put it into the AC100.
- Restart the AC100 normal.
- Installation to mmcblk0p7? ⇒ yes [it is the biggest partition 14, the storage-partition of android]
- After a automatical reboot some error message ocurrs (plymouth…). But it doesn't matter.
- Now go through the normal installation process.
- If the mouse pointer freezes please unplug the usb stick and plug in a usb mouse.
- If all finished, please upgrade with the following: sudo apt-get update && sudo apt-get install linux-ac100
Same as the above but use the rootfs from here: http://cdimage.ubuntu.com/releases/oneiric/release/
Install instructions can be found here: https://wiki.ubuntu.com/ARM/TEGRA/AC100
Note on suspend: It works out of box if you're running Android 2.1 bootloader, otherwise you'll need either revert to 2.1 or tweak /boot/bootimg.cfg:
- remove lp0_vec option from cmdparam line in /boot/bootimg.cfg
- <ctrl-C> whole line with resulting cmdline
- execute sudo abootimg -u /dev/mmcblk0p2 -c ”<ctrl-V>”

linux-ac100 package is provided in Oneiric repositories, not need to add ppa. Atomatic kernel update is supported.
With Beta 2 release and kernel 2.6.38-1000-ac100 as provided in the Oneiric repository since 2011/09/24 all the features of previous versions are supported (suspend, headphone sound, lid events) and we recommend an Oneiric install instead of Natty.
Anyway, it is adviseable to use some lightweight desktop environment. I can recommend LXDE on the Ubuntu basis. It is much faster regarding boot time, tool launch, file manager, etc and uses less RAM/eMMC in contrast to Ubuntu Unity/Gnome. — Peter Ibach 2011/10/02 15:58
See ubuntu_deubuntuization on how to cleanup your installation.
- phh (ubuntu with kernel version 2.6.32, working suspend and headphones audio)
- ubuntu (offical ubuntu page with install instructions for kernel version 2.6.38 and later. Automatic kernel updates through Oneiric repositories or PPA 2) for Natty. Status 2011/10/01, Ubuntu Oneiric Ocelot Beta 2 with kernel 2.6.38-1000-ac100: suspend works with Android 2.1 bootloader, audio working over headphones
