+// Description:
+// OFBD Default Command Configuration provides BIOS an oppertunity to override end user issued command in AFU.
+//
+// For example, BIOS could disable /k command even user issued it in AFU, or automatically enable /b when /p
+// is issued.
+//
+// For AFU¡¦s "/Ln" and "/Kn" two commands parameter identify. That AFU will replace the OFBD_EXT_TBL_END data
+// from 0xFFFF55AA to OFBD_TC_51_DC_EXT_STRUCT. Therefore, BIOS can through the "ddIndexCfg" flag to identify
+// who is this command structure. (The AFU version 3.05.1 or later supports.)
+//
+// Please reference OFBDDEFCFGHandle for more details.
