     ec - 3Com EtherLink II Ethernet (3c503) driver

SYNOPSIS    [Toc]    [Back]

     ec0 at isa? port 0x250 iomem 0xd8000 irq 9

DESCRIPTION    [Toc]    [Back]

     The ec device driver supports 3Com EtherLink II (3C503) Ethernet cards.
     Other  models  of  3Com  network  cards are supported by the
ef(4), eg(4),
     el(4), ep(4), ie(4), and xl(4) drivers.

     The EtherLink II supports two media types on a single  card.
All support
     the  AUI  media  type.  The other media is either BNC or UTP
behind a
     transceiver.  Software cannot differentiate between BNC  and
UTP cards.

     The ec driver supports the following media types:

           10base5  Set 10base5 (thick-net) operation.

           10base2   Set BNC (10base2/thin-net) or UTP operation.

     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 ec0''.

DIAGNOSTICS    [Toc]    [Back]

     ec0:  wildcarded  IRQ is not allowed  The IRQ was wildcarded
in the kernel
     configuration file.  This is not supported.

     ec0: invalid IRQ <n>, must be 3, 4, 5, or 9   An  IRQ  other
than the above
     listed  IRQs was specified in the kernel configuration file.
The EtherLink
 II hardware only supports the above listed IRQs.

     ec0: failed to clear shared memory at offset <off>  The memory test was
     unable  to clear the interface's shared memory region.  This
often indicates
 that the card is configured at a conflicting iomem address.
