10. Handling Zauri

This chapter is only a reminder, which helps me on the horse, when handling my CL860 and SL5500. It describes the different possibilities to use system-menus, ...

Up to now it is only a quick reference for the CL860 (as I always forget how to e.g. switch to flash-menu).

This does not really belong here and may be changed in the future.

10.1 Models and Name

• SL-5000D or SL-5500 (Collie)
• SL-5600 (Poodle)
• SLC-700 (Corgi)
• SLC-750 (Shepherd)
• SLC-760 (Husky)
• SLC-860 (Boxer)
• SL-6000 (Tosa)

10.2 CL860

This section cares for the CL860, but should als cover the CL750/760 and the other clamshell models.

ServiceMenu

The service menu may be used for NAND Flash Backup. This is a full copy of the Z and e.g. can be used to make a copy of the sharp original ROM.

To reach the Service-Menu follow the steps below.

• Unplug Power
• Unlock battery
• Remove battery cover
• Remove battery
• Press D+M and insert battery
• If nothing happens : Switch on Power or try again.

FlashMenu

The Flash-Menu can be used to reflash the user partition (e.g. with a new OZ-Image).

• Unplug Power
• Unlock battery
• Remove cover
• Remove battery
• Wait 1 sec
• Insert battery
• Close cover
• Lock battery
• Plugin Power
• Press "OK"-Button + "ON/OFF"

Important hint : Save all your user data before flashing a new image. All unsaved data will be lost.

To flash an image, you have to use a VFAT formatted (not EXT2 or so) CF disk or SD Disk with the following 3 files in its root dir.

• updater.sh
  The script handling the update. The Scripts can be found e.g. here.
• zImage.bin (exactly named like that).
  This is the new kernel, which have to be renamed to that name ( e.g. mv zImage-husky-20050121183004.bin zImage.bin).
• initrd.bin (exactly named like that).
  This is the new initial RAM disk, which have to be renamed to that name ( e.g. mv opie-image-husky-20050205085722.rootfs.img initrd.bin).

Note, that you may flash the kernel only, if initrd.bin is not found (e.g. renamed). The same is possible with initrd.bin only.

To flash, follow the steps below.

• The Display show a menu with 4 Japanese buttons.
• Selecting flash option (Button 4)
• Select Button 2 (CF)
• Left of two buttons (OK)

SysRq keys

Some special kernel functions can be reached using the SysRq function.

• Kernel 2.4 Fn + Home pressed together, release the Fn (keep Home pressed). Press the SysRq key.
• Kernel 2.6 RightJapaneseKey + Home pressed together, release the RightJapaneseKey (keep Home pressed). Press the SysRq key.

The following paragraph describes some helpfull SysRq keys (read src/linux/Documentation/sysrq.txt) for more information.

• s works with OZ
  Does an "Emergency Sync", which tries to sync all mounted filesystems (to guarantee a non corrupt filesystem).
• b works with OZ
  "Reboot". Immediately reboot the system without syncing or unmounting your disks into the low level bootloader and waits for the "ON/OFF" button to be pressed.
• o does not work with OZ
  "Off". Will shut your system off (if configured and supported).
• u
  Will attempt to remount all mounted filesystems read-only.
• p does not work with OZ
  Will dump the current registers and flags to your console.
• t works with OZ
  Will dump a list of current tasks and their information to your console.
• m works with OZ
  Will dump current memory info to your console.
• 0-9 works with OZ
  Sets the console log level, controlling which kernel messages will be printed to your console. ('0', for example would make it so that only emergency messages like PANICs or OOPSes would make it to your console.)
• e works with OZ
  Send a SIGTERM to all processes, except for init.
  Note, that a Fn+Right will lock the system now.
• i works with OZ
  Send a SIGKILL to all processes, except for init. Note, that a Fn+Right will lock the system now.
• h works with OZ
  Will display help ( actually any other key than those listed above will display help. but 'h' is easy to remember :-)
