The MVME230x module uses Digital EquipmentÕs DECchip
21140/21143 PCI Fast Ethernet LAN controller to implement an
Ethernet interface that supports 10Base-T/100Base-TX connections,
via an RJ45 connector on the front panel. The balanced differential
transceiver lines are coupled via on-board transformers.
Every MVME230x is assigned an Ethernet station address. The
address is $08003E2xxxxx, where xxxxx is the unique 5-nibble
number assigned to the board (i.e., every board has a different
value for xxxxx).
Each MVME230x displays its Ethernet station address on a label
attached to the base board in the PMC connector keepout area just
behind the front panel. In addition, the six bytes including the
Ethernet station address are stored in the NVRAM (BBRAM)
configuration area specified by boot ROM. That is, the value
