NAME    [Toc]    [Back]

     we - device driver for Western Digital/SMC WD80x3, SMC Elite
Ultra, and
     SMC EtherEZ Ethernet cards

SYNOPSIS    [Toc]    [Back]

     we0 at isa? port 0x280 iomem 0xd0000 irq 9
     we1 at isa? port 0x300 iomem 0xcc000 irq 10
     we* at isapnp?

DESCRIPTION    [Toc]    [Back]

     The  we  device  driver supports Western Digital/SMC WD80x3,
SMC Elite Ultra,
 and SMC EtherEZ Ethernet cards.

MEDIA SELECTION    [Toc]    [Back]

     The ability to select media from software  is  dependent  on
the particular
     model  of  WD/SMC  card.   The following models support only
manual configuration:
 WD8003S, WD8003E, and WD8013EBT.

     Other WD/SMC 80x3 interfaces support two types of media on a
single card.
     All  support  the AUI media type.  The other media is either
BNC or UTP being
 a transceiver.  Software  cannot  differentiate  between
     cards.  On some models, the AUI port is always active.

     The SMC Elite Ultra and SMC EtherEZ interfaces support three
media on a
     single card: AUI, BNC, and UTP.  If the transceiver  is  active, the BNC
     media  is  selected.   Otherwise,  the AUI and UTP ports are
both active.
     Cards of this vintage may also be found which  lack  one  or
two of the connectors.
  These cards also know what interrupt they are configured for,
     and will correct such problems (for  further  interrupt  issues, see isa(4)
     and pci(4)).

     The  SMC  EtherEZ  does  not yet work correctly in isapnp(4)
mode.  The SMC
     Elite Ultra does not work in ``soft configuration'' mode.

     To enable the AUI media, select the  10base5  or  aui  media
type with
     ifconfig(8)'s  `media' directive.  To select the other media
 select the 10base2 or bnc media type.

DIAGNOSTICS    [Toc]    [Back]

     we0: overriding IRQ <n> to <m>  The  IRQ  specified  in  the
kernel configuration
  file is different from that found in the card's configuration registers.
  The value in the kernel configuration file is being
     by the one configured into the card.

     we0: can't wildcard IRQ on a <model>  The IRQ was wildcarded
in the kernel
 configuration file, and the card is a WD8003S,  WD8003E,
or WD8013EBT,
     which do not support software IRQ configuration.

     we0: 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.
