The ep device driver supports the 3Com EtherLink III and Fast EtherLink III family of Ethernet cards. This includes, among others, the following models: 3C509 EtherLink III ISA 3C509B EtherLink III ISA (Plug-and-Play) 3C556 EtherLink III LAN+Modem PC Card (PCMCIA) 3C562 EtherLink III LAN+33.6K Modem PC Card (PCMCIA) 3C574 Fast EtherLink III 10/100 LAN PC Card (PCMCIA) 3C589 EtherLink III LAN PC Card (PCMCIA) 3C590 Fast EtherLink III PCI 3C595 Fast EtherLink III PCI 10/100 Other models of 3Com network cards are supported by the ec(4), ef(4), eg(4), el(4), ie(4), and xl(4) drivers. Category 3, 4 or 5 unshielded twisted-pair (UTP) cable should be used for RJ-45 (10baseT), thick Ethernet coaxial (RG59 B/U, 50 ohm) for AUI/DIX, and thin Ethernet coaxial (RG58 A/U or C/U, 50 ohm +/- 4) for BNC (10base2). Some 3Com NICs also support MII connectors (switchable 10/100Mbps UTP). The following media types and options (as given to ifconfig(8)) are sup- ported: media autoselect Enable autoselection of media type and options. media 100baseTX mediaopt full-duplex Set 100Mbps (Fast Ethernet) operation and force full-duplex mode. media 100baseTX mediaopt half-duplex Set 100Mbps (Fast Ethernet) operation and force half-duplex mode. media 10baseT mediaopt full-duplex Set 10baseT (UTP) operation and force full-duplex mode. media 10baseT mediaopt half-duplex Set 10baseT (UTP) operation and force half-duplex mode. media 10base5 Set 10base5 (thick-net) operation (half-duplex only). media 10base2 Set 10base2 (thin-net) operation (half-duplex only). Note that the 100baseTX media type is only available if supported by the adapter. For more information on configuring this device, see ifconfig(8). To view a list of media types and options supported by your card try "ifconfig -m <device>". For example, "ifconfig -m ep0". If more than one of the supported cards is installed, they are probed for in the following order: 1. PCI cards based on PCI function number order. 2. ISA cards based on increasing Ethernet address order. 3. Any ISA cards in Plug-and-Play mode, in Plug-and-Play order. You may specify the port and IRQ numbers where the cards are expected to be found, but it is not necessary. The cards are intelligent enough to let us know where they live on the bus.
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: erase pencil mark, or disable PnP mode! 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).
