The
sm device driver supports SMC91C9x 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 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.
The SMC91C1xx supports the following media types:
-
-
- autoselect
- Enable autoselection of the media type and options. The user can manually
override the autoselected mode by adding media options to the appropriate
hostname.if(5)
file.
-
-
- 10baseT
- Set 10Mbps operation. The mediaopt option
can also be used to select either
full-duplex or
half-duplex modes.
-
-
- 100baseTX
- Set 100Mbps (Fast Ethernet) operation. The
mediaopt option can also be used to
select either full-duplex or
half-duplex modes.
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.
For more information on configuring this device, see
ifconfig(8).
