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.
