NAME

     sm - device driver for SMC91C9x-based Ethernet interfaces


SYNOPSIS

     sm0 at isa? port 0x300 irq 10
     sm* at pcmcia? function ?


DESCRIPTION

     The sm device driver supports SMC91C9x-based Ethernet interfaces.

     The ISA attachment of the sm driver supports any SMC91C9x-based Ethernet
     interface on the ISA bus, including the EFA Info*Express SVC VLB inter-
     face, and the on-board SMC91C9x Ethernet found in many embedded PCs and
     laptop docking stations.

     The PCMCIA attachment of the sm driver supports Megahertz X-JACK Ethernet
     cards.


MEDIA SELECTION

     The SMC91C9x supports AUI and UTP media types.

     To enable the AUI media, select the 10base5 or aui media type with
     ifconfig(8)'s `media' directive.  To select UTP, select the 10baseT or
     utp media type.


DIAGNOSTICS

     sm0: unable to read MAC address from CIS  This indicates that the Ether-
     net address, which is stored in the CIS information on the Megahertz X-
     JACK PCMCIA Ethernet card, is corrupted.
