NAME
     sm -- SMC91Cxx-based Ethernet interfaces device driver

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

DESCRIPTION
     The sm device driver supports SMC91C9x-based and SMC91C1xx-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 mhzc attachment of the sm driver supports the Megahertz combo Ether-
     net and modem card.

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

     The nubus attachment of the sm driver supports SMC-based Ethernet cards
     for the macintosh.

MEDIA SELECTION
     The SMC91C1xx supports the MII interface and so the list of supported
     media depends on several factors, including which PHY is attached.  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.

     ifconfig(8)'s -m option will display the full list of supported media
     directives for a particular configuration.

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.
