+ 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.
