emgd.reg File Backward Compatibility
Intel® Embedded Media and Graphics Driver expects a configuration file in the PCFVersion 700 format. However, the driver currently supports backward compatibility with version 4.0. This support is not guaranteed, and will be discontinued at a later release. This support is implemented through the PcfVersion key as shown below:
[HKEY_LOCAL_MACHINE\Drivers\Display\Intel\ALL\1\General]
Intel® EMGD uses this key to determine the format of the configuration file. When this key is present, Intel® EMGD parses the configuration file using the format specified by the key (400 or 700). If this key is not present, then Intel® EMGD assumes 4.0 format.
