While installing a dual P6/200 with an on-board 10Mbit pcnet32 and an eepro100 card (eth0 and eth1 respectively recognized by the installer), installation assumed eth0 as the installation device (which wasn't hooked up to a switch at the time... had to move over the wire from the eepro100). Selectable when num_eth > 1 would be nice :)
