help
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.
