+	  The Intel Firmware Descriptor supports preventing write accesses
+	  from the host to the ME or TXE section in the firmware
+	  descriptor. If the section is locked, it can only be overwritten
+	  with an external SPI flash programmer. You will want this if you
+	  want to increase security of your ROM image once you are sure
+	  that the ME/TXE firmware is no longer going to change.

+	  If unsure, say N.
