-	  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

-	  firmware might be provided in coreboot's 3rdparty/blobs 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.
