+;* Description: Handles an SCI generated by the graphics driver. The
+;* PARM and SCIC input fields are parsed to determine the
+;* functionality requested by the driver. GBDA or SBCB
+;* is called based on the input data in SCIC.
+;*
+;* Usage: The method must be called in response to a GPE 06 event
+;* which will be generated by the graphics driver.
+;* Ex: Method(\_GPE._L06) {Return(\_SB.PCI0.GFX0.GSCI())}
+;*
+;* Input: PARM and SCIC are indirect inputs
+;*
+;* Output: PARM and SIC are indirect outputs
+;*
+;* References: GBDA (Get BIOS Data method), SBCB (System BIOS Callback
+;* method)
