Hello,

This issue is solved.
Fei, your tip concerning the Intel Firmware Descriptor was good.

Another tip came from here: http://www.sublab.org/wiki/coreboot-x201/

I've found an Intel tool 'fict', with which I could build a valid 
descriptor (checked by the 'ifdtool').
Enabling the INCLUDE_ME and ME_PATH in coreboot does the rest.

Now, the Mohon Peak CRB boots with all internal GbE enabled and 
functionning.

Thank to all.
Kind regards,
Patrick Agrain
