Auto-detected as a Tulip-compatible ethernet adapter. However, the install subsequently was hampered by the infamous configuration of automatic update.
To re-start the Ethernet adapter, I pulled the Ethernet cable in and out, and also dropped into the the shell (with Ctrl-Alt-F2) to `ifdown eth0' and eventually `rmmod tulip' and `rmmod dmfe'. `Dmfe' is the other driver which can be used with this Ethernet adapter. You can return to the graphical install with Ctrl-F7.
I settled on manual IP setup, rather than DHCP. Nameservers for Bigpond ADSL (Victoria) are 126.96.36.199 and 188.8.131.52.
