The Ethernet interface is provided by two Fast Ethernet PCI controller
chips. The presence of the Ethernet device can be positively determined by
reading the Vital Product Data Serial EEPROM which provides storage of
the MVME5100 hardware configuration.
Up to two PMC slots and one PCIX slot may be present. The presence of
the PMC's and/or PCIX can be positively determined by reading the Base
Module Feature Register. The INTA#, INTB#, INTC#, and INTD# from
the three PMC/PCIX slots are routed by MVME5100 as follows:
