Sharp Zaurus SL-C3000 Instruction Manual page 44

my Zaurus SL-C3000 and SL-C3100
This is the emergency partition that you usually don't see. You will need to manually mount the
usual partitions if you want to access them. /home is /dev/mtdblock3 and /dev/mtdblock2 is your
root partition. Don't forget to unmount the partitions after you have finished your changes or they
will be rolled back and all the files remain unchanged.
Zaurus ROM Update
For the C3000, you should update your Sharp ROM to 1.11JP if you are still on 1.01JP
There is no updated Sharp ROM for the C3100 yet.
Put card_update_3000111.exe onto a Windows machine (you got one of those right?) and run
it to extract the files. (it's a self extracting zip file).
Then copy all the extracted files to a SD or CF card (if your windows box has no card reader,
then put the memory card into your Zaurus and connect it via USB cable and switch it to share
your card instead of your hdd so you can transfer the files directly to the card). Make sure you
put the files into the card's root directory, ie don't put them into any folder and don't copy the
folder they were in.
The following files should be on the root of your memory card:
initrd.bin(about 4,337KB)
zImage.bin(about 1,264KB)
mversion.bin(about 16KB)
updater.sh(about 7KB)
hdimage1.tgz(about 19,734KB)
Turn off your Zaurus and disconnect the power cable (and any other cables). Unlock the
battery compartment and press the little reset button with your stylus. Put the lid back on and
make sure to lock it again.
Now make sure your Zaurus is plugged in to the AC power. You don't want to be on battery
power and have your Zaurus run out of juice in the middle of the update process (you can kiss
your Zaurus goodbye if that happens). Also make sure your card with the update files is
inserted.
The charge indicator should be orange now. Hold the "OK" key on the keyboard or the back of
the Zaurus and turn on the device with the "On/Off" button.
You should see the maintenance menu and select option 4 to update/flash the ROM. On the
next screen, select either 1. CF or 2. SD depending on where your update files are. Now
confirm to proceed with the update by selecting Y. Wait about 5 minutes after which your
Zaurus should reboot. You're done. You should have 1.11 JP ROM now.
Warning: Only flash your Zaurus with a ROM intended for your specific model and make sure you
downloaded the complete files. Never ever flash your Zaurus with a ROM for another model. It will
cause you many sleepless nights trying to restore it to a working condition.
Zaurus Kernel Replacement
There are several replacement kernels for the C3000 and C3100 which enhance the stock kernel
that ships with Sharp's ROM. You can even build your own if you want (and know how to). The
kernel source is available on Sharp's developer website. However, there are some smart people who
already build and tested their own enhanced kernels. One of those is Tetsu's special kernel which
has been build for optimised speed and also includes iptables and bluetooth modules. It also makes
the battery status more accurate and it has a few bug fixes too.
Warning: The kernel is an important part of the Linux OS. A bad kernel can corrupt your Zaurus,
so don't play around with it unless you know what you are doing and install the correct kernel for
your model.
Download and place the files onto a CF or SD card.
Turn off your Zaurus. (suspend it).
Unlock the battery compartment and push the little reset button.
Put the lid back on and lock it again.
Plug your Zaurus into the AC power.
