+  @par Protocol Description:
+  This protocol contains the EDID information retrieved from a video output device.
+
+  @param SizeOfEdid 
+  The size, in bytes, of the Edid buffer. 0 if no EDID information
+  is available from the video output device. Otherwise, it must be a
+  minimum of 128 bytes.
+  
+  @param Edid 
+  A pointer to a read-only array of bytes that contains the EDID
+  information for an active video output device. This pointer is
+  NULL if no EDID information is available for the video output
+  device. The minimum size of a valid Edid buffer is 128 bytes.
+  EDID information is defined in the E-DID EEPROM
+  specification published by VESA (www.vesa.org).
