The instructions on the OZ site are for the sl-5500
Before you istall, you should know that OZ is not stable on the sl-5600.
Here is how I did it ...
Go to the download section here and download 5600 v1.32-card.zip from the sharp rom section.
Unzip 5600 v1.32-card.zip to your CF card.
Delete initrd.bin updater.sh and zImage.bin from your CF card.
Go to
http://openzaurus.org/official/3.3.5/poodle/ and download initrd-gcc3.bin updater.sh and zImage.bin to your CF card.
rename initrd-gcc3.bin to initrd.bin
Insert your CF into the zaurus and remove the battery cover. Press the reset button below the battery, replace the cover and flip the switch back to normal operation. Make sure your power card is plugged in.
Hold down the OK button and press the cancel button. You should see a menu. Choose update. Then choose CF card.
Wait for it to flash...
Some of those steps may not be needed (like the sharp rom zip file), but thats what I did to make it install.
I\'m now using the tkcrom. It is stable, as is the Zynergy5600 rom.
