| 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. |

| 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. |
