6.1.2.4 Replacing the boot loader
The boot loader can be automatically replaced/set during a firmware update.
6.1.2.5 Replacing the boot bitmap
The boot bitmap, that is displayed directly when the device is booted and switched on, can be automatically
replaced/set during a firmware update. In this way, it is possible to customise the boot bitmap.
6.1.2.6 Updating the flash disk
The system programs are stored in the \flashdisk\system and \flashdisk\drivers folders. These cannot be
simply deleted and re-configured as the programs in these folders are in use. The procedure below
describes how to update the flash disk:
-
Rename the system and drivers folders, e.g. into system.old and drivers.old
-
Copy the new system and drivers folders to the device
-
Delete the registry with Start
Programs
SysTools
SysTools
-
Reboot the device with Start
Programs
ACD
System
CEReboot
-
Run any update batches on the desktop
-
Delete the folders you have renamed in step 1
By following the steps above, the ACD system programs and drivers are updated and the registry is
configured with the new default parameters.
Keyboard controller, PLD and boot loader are also updated in the flash disk folders created by ACD.
If a .CAB file is launched to execute the update, the installation steps are carried out automatically.
6.1.2.7 Updating the keyboard controller and PLD
Keyboard controller and PLD can be manually updated with the CEHWProg.exe program. These
components can also be updated as part of a general update or a flash disk update.
Risks are associated with an update of a keyboard controller or PLD. If the
programming fails (power interruption), the device must be sent to ACD for repair.
