Instruction to Backup/Restore you personal data/configuration on  Zaurus SLC-760

This readme explains how to backup and restore your personal data
files and configuration file before flashing your zaurus.


Method 1:

1.1 Copy the files in flash memory into your CF Card, for example:
    dd if=/dev/mtdblock# of=/home/samba/CF_Card/save/block#
for #=0 to 3

1.2 Configure your Linux PC/laptop to mount the file system:
    In your kernel configuration, activate (as modules, to not reboot :)):
       - in block devices, activate loopbackdevice
       - Memory Technology Devices (MTD)
	 - in selfcontained MTD device drivers, activate MTD emulation using block device
       - FileSystem/jffs2
    then type 
    # make dep && make modules && make modules_install

1.3 Mount your files as:
    # losetup /dev/loop0  /directory/where/you/saved/data
    # modprobe mtdcore
    # modprobe mtdblock
    # modprobe jffs2
    # modprobe blkmtd device=/dev/loop0
    # mount -t jffs2 -o ro /dev/mtdblock0 /mount/point/

Method 2:

Use the backup/restore software of the zaurus which backups your data on the CF Card.

Method 3:

Boot the Zaurus as you want to flash it: 
- unplug the AC power, 
- remove the battery pack during 5s at least 
- then re-plug the battery and AC power and simultaneously press 
  [Home - Power On] (keyboard button) and [ON-OFF power] (button at the back 
  of the zaurus)

Then choose the option "backup".
