BabbageJauntyBetaInstall
This page describes how to install a Jaunty beta image to a babbage board.
Image writing
First of all you need to dd the image from http://cdimage.ubuntu.com/releases/jaunty/beta/ to an SD card
sudo dd bs=4M if=./ubuntu-9.04-beta-desktop-armel+imx51.img of=/dev/mmcblk0
(assuming your SD card is called /dev/mmcblk0)
Starting the live system
Plug the SD card into the SD card slot of your babbage board, you need a USB mass storage device (e.g. USB key or disk) as target device attached, or a SATA disk attached.
Starting the installer
Now just doubleclick the "Install" icon on the desktop and follow the normal install procedure.
Note that it's hard to install to the SD card (/dev/mmcblk0) itself, you would have to create the partitions manually yourself first; it's preferable to install to an USB mass storage device or to a SATA disk instead.
After installation
You need to leave your SD card in the board as the boot device: the babbage currently only boots from SD. It will load your target installed system.
