.Dd $Mdocdate: December 3 2011 $ .Dt SM 4 .Os .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.
p 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.
p 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: l -tag -width full-duplex t 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. t 10baseT Set 10Mbps operation. The .Ar mediaopt option can also be used to select either .Ar full-duplex or .Ar half-duplex modes. t 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
p The SMC91C9x supports AUI and UTP media types:
p 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.
p For more information on configuring this device, see .Xr ifconfig 8 . .Sh DIAGNOSTICS l -diag t "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. .El .Sh SEE ALSO .Xr arp 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr isa 4 , .Xr netintro 4 , .Xr nsphy 4 , .Xr pcmcia 4 , .Xr hostname.if 5 , .Xr ifconfig 8
