Microsoft Windows* Embedded Compact 7 Configuration

The following sections describe how to configure the Intel® EMGD on the Microsoft Windows* Embedded Compact 7 operating system. All the Intel® EMGD-specific registry keys are located within the path [HKEY_LOCAL_MACHINE\DRIVERS\Display\Intel]

All keys use one of the following syntax:

“<keyname>”=dword:<value>,

or

“<keyname>” = <value>

where <value> in the second case is a string in double quotes.

Note: Unless specified otherwise, the “value” field is in hex format.

The emgd.reg file contains display configuration registry entries for the Intel® EMGD. A sample emgd.reg file is provided along with the driver package. The content of this file may be included through the “#include” directive in platform.reg (see Installation and Setup), or it may be copied into the proper section in platform.reg.
