|
.Nd i-cubed EtherLan 100/200/500-series (EtherH) Ethernet driver
|
|
.Sh SYNOPSIS
|
|
.Cd "eh* at podulebus0 slot ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides access to a 10 Mb/s Ethernet network through an
|
|
i-cubed EtherLan 100-series, 200-series or 500-series expansion card.
|
|
It also supports the Acorn-badged variants of the same cards, with part
|
|
numbers
|
|
.Tn AEH75 ,
|
|
.Tn AEH77
|
|
and
|
|
.Tn AEH79 .
|
|
.Pp
|
|
Media selection on cards supporting multiple media can be accomplished
|
|
either using
|
|
.Xr ifconfig 8
|
|
or using links on the card. The links override the software and make the
|
|
card behave as if only one medium is available. The media available,
|
|
subject to the hardware on the card, are:
|
|
.Bl -tag -width 10baseFL
|
|
.It auto
|
|
Automatically select 10BASE-T or 10BASE2. 10BASE-T will be used if a link
|
|
beat appears to be present on that interface. Otherwise, 10BASE2 will be used.
|
|
.It 10baseT
|
|
10BASE-T, 10Mb/s over unshielded twisted pair, RJ45 connector.
|
|
.It 10base2
|
|
10BASE2, 10Mb/s over coaxial cable, BNC connector, also called Thinnet.

.Sh BUGS
|
|
EtherLan 500-series support is untested.
|
|
.Pp
|
|
The 10BASE-FL port on the EtherLan 513 will probably be identified as 10BASE2.
