Control Panel Extension

    A control panel extension is provided to configure certain parameters 
of the driver like Compression, DDC, Panel Support  etc. The details of 
these parameters are as follows:

Registry Settings
	The driver behavior depends upon the way it has been configured. 
        This configuration mechanism is possible by registry settings. 
        Given below are the registry settings that change the behavior 
        of the driver.

	Compression
	This option enables the driver to enable or disable compression. 
        Compression is a hardware feature of Geode.
	By default this option is enabled.

	DDCEnabled
	This option enables the driver to query the monitor for the 
        best-supported resolutions. This will be disabled automatically 
        if flatpanel supported requested.
	By default this option is enabled.

	PanelSupport
	This option enables the driver to output on to flatpanel instead 
        of CRT (default). 
	This option only configures the output as flatpanel and doesn't 
        describe the way the hardware has been initialized. If this option 
        is enabled the DDC query is disabled.
	By default this option is disabled.

	PanelInitInBIOS
	This option enables the driver to use the flatpanel initialization 
        done in the BIOS. Here the BIOS is queried to find out the supported 
        flatpanel resolution. 
	This option needs the PanelSupport option to be enabled. This option 
        overrides the Platform option.
	By default this option is enabled.

	Platform
	This option enables the driver to use the flatpanel initialization done 
        by the driver. Here the hardware is queried to find out the supported 
        flatpanel resolution. The jumper settings on the board dictate the 
        desired resolution and works only on National Development Platforms. 
        The NSC Boards supported today are Centaurus and Dorado Platforms ONLY. 
	This option needs the PanelSupport option to be enabled, for this 
        option to be used disable PanelInitInBIOS.
	The default value is "0".

        |Platform    |   Value |
