-	  If you don't have an Intel Firmware Descriptor (ifd.bin) for your

-	  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

-	  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.
