Customization stick

The customization key allows you to install your own set of activities and library content on top of a signed OLPC build.

Preparing the key:

• Unpack customization-1.zip into the root directory of a USB key.
  • This will create an empty subdirectory 'bundles' and a subdirectory 'boot' containing two files 'runos.zip' and 'actos.zip'.
• Add 'fs.zip' and 'osXYZ.img' from the base build you want to install.
  • For example, the files for build 656 are at http://download.laptop.org/xo-1/os/official/656/jffs2/
• Drag the .xo files (activity bundles) and .xol files (library bundles) you want to install into the 'bundles' directory.
• If you create a zip file containing 'frame00.565' through 'frame26.565' and place it in 'bundles' with a name ending in '.pb', you can customize the boot sequence.

Using the key:

Once you've created your usb stick(s) in this way:

• Insert the stick into a powered-off XO
• Turn the machine on while holding down all four game pad keys.

The machine will erase all contents of the flash on the XO, install the base build, and then install your custom activity and content set. It will then power-off, and you can remove the stick and move on to the next XO.

NOTE: If your machine is unactivated, this key does not perform the activation step for you. You will need to Activate your XO in order to get the machine to boot after this process.

Advanced usage:

You can use this technique to upgrade activities without installing a new base build. Just insert the key and boot without holding down the gamepad keys.
