DESCRIPTION    [Toc]    [Back]

     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)
           3C579   EtherLink III EISA
           3C589   EtherLink III LAN PC Card (PCMCIA)
           3C590   Fast EtherLink III PCI
           3C592   EtherLink III EISA Bus Master
           3C595   Fast EtherLink III PCI 10/100
           3C597   Fast EtherLink III EISA 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 supported:


           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.  EISA cards based on EISA slot number order.
           3.  ISA cards based on increasing Ethernet address order.
           4.   Any ISA cards in Plug-and-Play mode, in Plug-andPlay 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.

DIAGNOSTICS    [Toc]    [Back]

     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).
