	  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 Management Engine supports preventing write accesses

	  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.
