ep -- Ethernet driver for 3Com Etherlink III (3c5x9)
The ep device driver supports network adapters based on the 3Com 3C5x9
Etherlink III Parallel Tasking chipset, like the following:
+o 3C1 CF
+o 3C509-TP, 3C509-BNC, 3C509-Combo, 3C509-TPO, 3C509-TPC ISA
+o 3C509B-TP, 3C509B-BNC, 3C509B-Combo, 3C509B-TPO, 3C509B-TPC ISA
+o 3C529, 3C529-TP MCA
+o 3C579-TP, 3C579-BNC EISA
+o 3C562/3C563 PCMCIA
+o 3C569B-J-TPO, 3C569B-J-COMBO CBUS
+o 3C574-TX, 3CCFE574BT, 3CXFE574BT, 3C3FE574BT PCMCIA
+o 3C589, 3C589B, 3C589C, 3C589D PCMCIA
+o 3CXE589EC, 3CCE589EC, 3CXE589ET, 3CCE589ET PCMCIA
+o Megahertz 3CCEM556, 3CXEM556, 3CCEM556B, 3CXEM556B PCMCIA
+o 3Com 3CCFEM556B, 3CCFEM556BI PCMCIA
+o OfficeConnect 3CXSH572BT, 3CCSH572BT PCMCIA
+o Farallon EtherMac PCMCIA
Various models of these cards come with a different assortment of connectors:
AUI/DIX Standard 15 pin connector, also known as 10base5
10Base2 BNC, also known as thin-net
10BaseT UTP, also known as twisted pair
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
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.
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 nonEISA
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).

Support for the 3COM 3C1 is not working. Support for the 3CCFEM556 fast
ethernet cards has not been tested.
are great. There's so many to choose from.
