         kernel configuration file:
    
               device ep
    
         Alternatively, to load the driver as a module at boot time, place the
         following line in loader.conf(5):
    
               if_ep_load="YES"
    
    
    

    DESCRIPTION

         The ep device driver supports network adapters based on the 3Com 3C5x9
         Etherlink III Parallel Tasking chipset.
    
         Various models of these cards come with a different assortment of connec-
         tors:
    
         AUI/DIX               Standard 15 pin connector, also known as 10base5
                               (thick-net)
    
         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.
    
    
    

    HARDWARE

         The ep driver supports Ethernet adapters based on the 3Com 3C5x9 Ether-
         link III Parallel Tasking chipset, including:
    
         ?   3Com 3C1 CF
         ?   3Com 3C509-TP, 3C509-BNC, 3C509-Combo, 3C509-TPO, 3C509-TPC ISA
         ?   3Com 3C509B-TP, 3C509B-BNC, 3C509B-Combo, 3C509B-TPO, 3C509B-TPC ISA
         ?   3Com 3C529, 3C529-TP MCA
         ?   3Com 3C562/3C563 PCMCIA
         ?   3Com 3C569B-J-TPO, 3C569B-J-COMBO CBUS
         ?   3Com 3C574, 3C574TX, 3C574-TX, 3CCFE574BT, 3CXFE574BT, 3C3FE574BT
             PCMCIA
         ?   3Com 3C579-TP, 3C579-BNC EISA
         ?   3Com 3C589, 3C589B, 3C589C, 3C589D, 3CXE589DT PCMCIA
         ?   3Com 3CCFEM556B, 3CCFEM556BI PCMCIA
         ?   3Com 3CXE589EC, 3CCE589EC, 3CXE589ET, 3CCE589ET PCMCIA
         EISA systems.
    
         Many different companies sold the 3Com PC Cards under their own private
         label.  These cards also work.
    
         The Farallon EtherWave and EtherMac card came in two varieties.  The ep
         driver supports the 595 and 895 cards.  These cards have the blue arrow
         on the front along with a 3Com logo.  The Farallon 595a cards, which have
         a red arrow on the front, are also called EtherWave and EtherMac.  They
         are supported by the sn(4) driver.
    
    
    

    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).
    
         ep0: No I/O space?!  The driver was unable to allocate the I/O space that
         it thinks should be there.  Look for conflicts with other devices.
    
         ep0: No irq?!  The driver could not allocate the interrupt it wanted.
         Look for conflicts, although sharing interrupts for PC Card is normal.
    
         ep0: No connectors!  The driver queried the hardware for what ethernet
         attachment were present, but the hardware reported none that the driver
         recognized.
    
         ep0: Unable to get Ethernet address!  The driver was unable to read the
         ethernet address from the EEPROM.  This is likely the result of the card
         being wedged.
    
         ep0: if_alloc() failed  The driver was unable to allocate a ifnet struc-
         ture.  This may happen in extremely low memory conditions.
    
         ep0: strange connector type in EEPROM: assuming AUI  The driver does not
         know what to do with the information the EEPROM has about connectors, so
         it is assuming the worst.
    
         ep0: unknown ID 0xXXXXXXXX  The driver has found an ID that it believes
         it supports, but does not have a specific identification string to
         present to the user.
    
         ep0: <%s> at port 0x%03x in EISA mode  The 3C509 ISA card is in EISA
         mode.  This message appears to be purely informational.
    
         ep0: <%s> at x0%03x in PnP mode  This card appears to be in Plug and Play
         are great.  There is so many to choose from.
    
    
    

    BUGS

         Support for the 3Com 3C1 CompactFlash is not working.
