The xl driver only does autonegotiation using 10/100 port: you can use the 10base2 port, but you have to select it manually. ifconfig_xl0="inet 10.0.0.1 media 10base2/BNC netmask 255.255.255.0" The 10/100 autonegotiation is carried out automatically by the transceiver hardware, but for 10base2, the driver would have to do a lot of its own work to test for media presence. The 3.x driver would attempt to use the media selection specified in the EEPROM (which can be changed with the 3C90XCFG.EXE utility that comes with the card), but the 4.x and later driver always defaults to autonegotiate. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
