Chapter 11: System Clone, Backup/Restore & ROM Upgrade
(Note: This is a feature applies to ROM version v1.0a or above)
Introduction
WF28 is the first POS PDA features powerful System Clone (similar to Ghost utility), Backup / Restore & ROM
upgrade tools at no additional cost. Since this is a feature fully integrated with System ROM, it is always
ready to use even the PDA is being configured starting from scratch after clean reset.
With backup tool and user mode locking PDA configurations, it dramatically changes the way of deploying &
supporting PDA solutions. To see the benefits, see the comparison below:
