.Dd November 2, 2003 .Dt EP 4 i386 .Os .Sh NAME .Nm ep .Nd Ethernet driver for 3Com Etherlink III (3c5x9) .Sh SYNOPSIS .Cd "device ep" .Sh DESCRIPTION The .Nm device driver supports network adapters based on the 3Com 3C5x9 Etherlink III Parallel Tasking chipset, like the following:
p l -bullet -compact t 3Com 3C1 CF t 3Com 3C509-TP, 3C509-BNC, 3C509-Combo, 3C509-TPO, 3C509-TPC ISA t 3Com 3C509B-TP, 3C509B-BNC, 3C509B-Combo, 3C509B-TPO, 3C509B-TPC ISA t 3Com 3C529, 3C529-TP MCA t 3Com 3C579-TP, 3C579-BNC EISA t 3Com 3C562/3C563 PCMCIA t 3Com 3C569B-J-TPO, 3C569B-J-COMBO CBUS t 3Com 3C574-TX, 3CCFE574BT, 3CXFE574BT, 3C3FE574BT PCMCIA t 3Com 3C589, 3C589B, 3C589C, 3C589D, 3CXE589DT PCMCIA t 3Com 3CXE589EC, 3CCE589EC, 3CXE589ET, 3CCE589ET PCMCIA t Megahertz 3CCEM556, 3CXEM556, 3CCEM556B, 3CXEM556B PCMCIA t 3Com 3CCFEM556B, 3CCFEM556BI PCMCIA t 3Com OfficeConnect 3CXSH572BT, 3CCSH572BT PCMCIA t Farallon EtherMac PCMCIA .El
p Various models of these cards come with a different assortment of connectors:
p l -tag -width xxxxxxxxxxxxxxxxxxxx t AUI/DIX Standard 15 pin connector, also known as 10base5 (thick-net) t 10Base2 BNC, also known as thin-net t 10BaseT UTP, also known as twisted pair .El
p The default port to use is the port that has been selected with the setup utility. To override this, use the following media options with .Xr ifconfig 8 or in your
p l -tag -width xxxxxxxxxxxxxxxxxxxx t 10base5/AUI Use the AUI port. t 10base2/BNC Use the BNC port. t 10baseT/UTP Use the UTP port. .El
p If there are multiple cards in the computer, they are searched for in the following order: bus, slot, then ethernet address. .Sh 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!
p 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. .Sh DIAGNOSTICS l -diag t 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. t ep0: eeprom failed to come ready The eeprom failed to come ready. This probably means the card is wedged. t 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). .El .Sh SEE ALSO .Xr ed 4 , .Xr el 4 , .Xr ie 4 , .Xr intro 4 , .Xr le 4 , .Xr ng_ether 4 , .Xr vx 4 , .Xr ifconfig 8 .Sh BUGS Support for the 3COM 3C1 is not working. Support for the 3CCFEM556 fast ethernet cards has not been tested. .Sh STANDARDS are great. There's so many to choose from.
