Our system (MFSYS25V2) have two compute modul. The firmware is the latest. Both compute modul have a mezzanine card.
In the server general tab:
MAC3 NOT AVAILABLE: Ethernet Mezz Card not present
MAC4 NOT AVAILABLE: Ethernet Mezz Card not present
But the compute module BIOS seen the Mezz cards, and the server Mezzanine tab have info too (serial number, etc).
