+	  If you don't have an Intel Firmware Descriptor (ifd.bin) for your
+	  board, you can select this option and coreboot will build without it.
+	  Though, the resulting coreboot.rom will not contain all parts required
+	  to get coreboot running on your board. You can however write only the
+	  BIOS section to your board's flash ROM and keep the other sections
+	  untouched. Unfortunately the current version of flashrom doesn't
+	  support this yet. But there is a patch pending [1].
+
+	  WARNING: Never write a complete coreboot.rom to your flash ROM if it
+		   was built with a fake IFD. It just won't work.

+	  The Intel processor in the selected system requires a special firmware
+	  for an integrated controller called Management Engine (ME). The ME
+	  firmware might be provided in coreboot's 3rdparty repository. If
+	  not and if you don't have the firmware elsewhere, you can still
+	  build coreboot without it. In this case however, you'll have to make
+	  sure that you don't overwrite your ME firmware on your flash ROM.

+	default n
+	help
+	  The Intel Management Engine supports preventing write accesses
+	  from the host to the Management Engine section in the firmware
+	  descriptor. If the ME 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 firmware is no longer going to change.
+
+	  If unsure, say N.
