+ 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.
