Build a Custom OpenZaurus ROM for the Zaurus PDA

"Howto build a custom ROM for the Zaurus. Note: Following this howto has the potential of making a nice paperweight out of your Zaurus. Do this at your own risk. There are no guarantees that this will work. Whether or not you upgrade your filesystem, you'll have to do a hard reset during this process, and so you're going to lose all of your data, and any applications you've installed yourself. Now would be a good time to backup anything that you want to keep.
