+.Sh NAME
+.Nm sm
+.Nd SMC91C9x and SMC91C1xx-based 10/100 Ethernet device
+.Sh SYNOPSIS
+.Cd "sm0 at isa? port 0x300 irq 10"
+.Cd "sm* at pcmcia?"
+.Cd "nsphy* at mii?"
+.Sh DESCRIPTION
+The
+.Nm
+device driver supports SMC91C9x and SMC91C1xx-based Ethernet interfaces.
+.Pp
+The ISA attachment of the
+.Nm
+driver supports any SMC91C9x-based Ethernet interface on the ISA
+bus, including the EFA Info*Express SVC VLB interface, and the
+on-board SMC91C9x Ethernet found in many embedded PCs and laptop
+docking stations.
+.Pp
+The PCMCIA attachment of the
+.Nm
+driver supports Megahertz X-JACK Ethernet cards, NewMedia BASICS Ethernet
+cards, and SMC EtherEZ 8020 series cards.
+.Sh MEDIA SELECTION
+The SMC91C1xx supports the following media types:
+.Bl -tag -width full-duplex
+.It autoselect
+Enable autoselection of the media type and options.
+The user can manually override the autoselected mode by adding media options
+to the appropriate
+.Xr hostname.if 5
+file.
+.It 10baseT
+Set 10Mbps operation.
+The
+.Ar mediaopt
+option can also be used to select either
+.Ar full-duplex
+or
+.Ar half-duplex
+modes.
+.It 100baseTX
+Set 100Mbps (Fast Ethernet) operation.
+The
+.Ar mediaopt
+option can also be used to select either
+.Ar full-duplex
+or
+.Ar half-duplex
+modes.
+.El
+.Pp
+The SMC91C9x supports AUI and UTP media types:
+.Pp
+To enable the AUI media, select the
+.Em 10base5
+or
+.Em aui
+media type with
+.Xr ifconfig 8 Ns 's
+.Sq media
+directive.
+To select UTP, select the
+.Em 10baseT
+or
+.Em utp
+media type.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "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.
