4-2-2 Overwrite Factory Default
Architecture Introduction:
The Manufacturer provides a mechanism to merge the OEM application and
OEM specific settings into WindowCE operating system during booting phase.
This feature can make OEM stuffs as system default components. There are
many benefits for device maintenance.
It is a valuable feature for OEM doesn’t have to reinstall OEM programs after
end user reset the device to factory default mode. This benefit also helps to
reduce the RMA cost from OEM vender.
Because of this system architecture, WindowCE operating system and OEM
application programs are not merged together. So both parts can be
upgraded separately.
Architecture of the OEM Device Manager
System Integrator should base on the directory structure of WindowCE to
prepare the OEM installation files in SD card. All files in “GHARST” file
directory would be copy into WindowCE file system during cold booting phase.
By the way, the config files in “configfiles” directory are for system registry
maintenance.
