Sharp Zaurus SL-C3000 Instruction Manual page 155

my Zaurus SL-C3000 and SL-C3100
if you are a newbie. Advanced users still should be very careful when they try out the other beta
distros. Keep in mind that putting another distro onto the SL-C3000 will wipe everything on it so
make sure you make appropriate backups before doing so.
Since I have two Zauri, both the SL-C3000 and the SL-C3100, I can make one of them my stable
working mini laptop with all my customised settings, applications and data while the other one will
be used for application development for the Z and trying out other ROMs/distros. Ultimately, I will
need a better alternate distro for my SL-C3000 since the default Sharp ROM or Cacko are too
limiting for its small 4MB home partition. My SL-C3100 on the other hand is functioning perfectly
with a customised Sharp ROM and X/Qt (see pdaXqtrom for details on running a host of X
applications on the default Sharp distro).
Cacko
The Cacko distro is an improved Sharp distro which basically fixes a lot of the shortcomings of the
Sharp distro. Also, Sharp distro is by default completely in Japanese. The Cacko distro is essentially
Sharp distro completely translated into English with updated driver support.
The Cacko 1.23 release was mainly aimed at the SL-C1000, with the SL-C3100 being treated just
like a SL-C1000 with an internal CF. Nothing is put on the internal MicroDrive, so it remains
untouched by the Cacko installation. Cacko 1.23 is released in two editions, the full edition and a
lite edition.
The lite edition is a barebone distro where most the pre-installed applications and modules have
been removed to give you the maximum of available space on the flash. All the left out applications
and modules can be installed from the Cacko feed. They all have a lite in their package names for
easy identification.
The full Cacko 1.23 distro is very similar to the Sharp distro. It enhances the kernel with patches
similar to the Tetsu special kernel and also adds additional filesystem support such as squashfs, hfs,
iso/joliet, ntfs and fuse. The main difference between the Cacko ROM and the Sharp one is that it is
completely in English and all the Japanese components, including the dictionaries have been
removed. Also, a lot of work has been put into networking and bluetooth support, thus a lot of the
network and bluetooth adaptors, both CF based ones as well as USB dongles, are automatically
recognised and just work with Cacko without the need of installing and configuring drivers for them.
Some of the default applications that come with the Sharp distro have also been replaced with
better alternatives, in particular the ones that were Japanese only applications. In addition, a
number of essential Linux tools and Qtopia based applications have also been added and are
available on Cacko pre-installed. See the Cacko release notes for a detailed list of added features.
To install Cacko, you would have to flash your SL-C3100 with the Cacko ROM. This will wipe your
entire flash, so make sure you do a Nand backup so you can restore your Zaurus to the previous
state in case you want to revert back, but also make a backup of your data if it is stored on the
flash since it gets wiped. The /hdd3 partition on your internal MicroDrive won't be wiped by flashing
the Cacko ROM so it is not essential to back it up prior to flashing Cacko, but it would be a good
idea anyway just in case something goes wrong. You do not need to resize the root partition for the
SL-C3100 because 32MB is the default root partition on the SL-C3100 unles you have changed it to
something else previously. The SL-C1000 has a default root partition of 64MB so repartitioning it on
the SL-C1000 will free up extra space for your user partition to install applications and to store user
data.
Thus for the SL-C3100, just flash the ROM without repartitioning root, ie use the Install new ROM
option straight away and say yes to format user partition. If you say no, just your root partition will
be reflashed and you get the Cacko kernel and config, but all your application binaries will remain
unchanged. Select Reboot when the flashing has finished and you are done.
There is a Cacko 1.23 beta available for the SL-C3000. Since the SL-C3000 has a very small flash
partition, installing another distro will wipe your entire MicroDrive. You won't be able to simply
make a Nand backup and restore your system if you want to revert back. You would need to rebuild
your SL-C3000 from scratch. However, the C3000 beta release of Cacko leaves your partition table
layout as is and just reformats your partitions. Be aware that the C3000 beta is quite different from
the normal 1.23 release of Cacko, it does not upgrade the kernel nor does it provide all the extra
