Once in a while, I see posts by new Zaurus owners on problems with the Cacko installation process, most probably due to the Japanese maintenance menu.
So I thought I'd supplement Mazlovsky's original instructions with screenshots (and some minor editing) where relevant.

IMPORTANT: This ROM requires a flash partition at least 32 MBytes in size!
Make sure to repartition your internal flash before updating ROM!
-------------------------------------------------------------------------------------
Installation:
1. Extract the 3 files - initrd.bin tools.tar updater.sh - to the root of your CF or SD/MMC card.
2. Make sure that Zaurus isn't plugged into AC power.
3. Remove battery for at least 5 seconds.
4. Replace battery (replace battery cover, lock cover), plug in AC power.
5. Press and hold the "OK" button on the keyboard.
6. Turn the power on, you should see the Maintenance Menu.

7. Now Plug in the Power Cord.
You will get an error if it isn't plugged in!
8. Select option 4 (flash/update).

And finally, reboot your Zaurus when ROM installation is complete.
