NAME
     sm - SMC91C9x-based Ethernet driver

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, NewMedia BASICS Ethernet cards, and SMC EtherEZ 8020 series 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.
