SUMMARY: Network Interface Identification

  Well, it was an easy one. The Sparc-10 automatically senses for
the "active" ethernet port upon reboot. The only difference in the
boot-up should be "le0: Twisted Pair Ethernet" instead of "le0: AUI
Ethernet".

  The "network interface" stays the same: le0. The board is wired:

CPU--->le0 802.3 AUI chip:----To connector ---: external thinwire---|
                         | at the back transceiver
                         |
                         +----internal 802.3 to Twisted: ------ TP
                                  pair transceiver

(diagram compliments of Marcel Bernards). For obvious reasons, double
line interfacing is not permitted...
