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 interface, and the on-board SMC91C9x Ether-
     net found in many embedded PCs and laptop docking stations.

     The mhzc attachment of the sm driver supports the Megahertz combo Ethernet 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 sev-
     eral 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 par-
     ticular configuration.

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