To override this, use the following media options with ifconfig(8) or in your /etc/rc.conf file. 10base5/AUI Use the AUI port. 10base2/BNC Use the BNC port. 10baseT/UTP Use the UTP port. If there are multiple cards in the computer, they are searched for in the following order: bus, slot, then ethernet address. NOTES The 3c509 card has no jumpers to set the address. 3Com supplies software to set the address of the card in software. To find the card on the ISA bus, the kernel performs a complex scan operation at IO address 0x110. Beware! Avoid placing other cards at that address! Furthermore, the 3c509 should only be configured in EISA mode when installed in a computer that has actual EISA slots (and an EISA-aware BIOS). The normal driver auto-detection support is sufficient for non- EISA systems. DIAGNOSTICS ep0: reset (status: %x) The driver has encountered a FIFO underrun or overrun. The driver will reset the card and the packet will be lost. This is not fatal. ep0: eeprom failed to come ready The eeprom failed to come ready. This probably means the card is wedged. ep0: 3c509 in test mode. Erase pencil mark! This means that someone has scribbled with pencil in the test area on the card. Erase the pencil mark and reboot. (This is not a joke). SEE ALSO ed(4), el(4), ie(4), intro(4), le(4), ng_ether(4), vx(4), ifconfig(8) STANDARDS are great. There's so many to choose from. FreeBSD 4.10 February 4, 1993 FreeBSD 4.10
