.Sh NAME
|
||||
.Nm eg
|
||||
.Nd Ethernet driver for 3Com 3c505 Etherlink+ Ethernet board
|
||||
.Sh SYNOPSIS
|
||||
.Cd "device eg0 at isa? port 0x310 net irq 5"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
interface provides access to a 10 Mb/s Ethernet network via the
|
||||
3Com 3c505 board based on the Intel 82586 Ethernet chip.
|
||||
.Sh DIAGNOSTICS
|
||||
.Bl -diag
|
||||
.It "eg%d: configure card command failed"
|
||||
For some reason, the driver could not initialize the card. Please check
|
||||
the card's IRQ and I/O settings relative to those in the kernel
|
||||
configuration file.
|
||||
.El
|
||||
.Pp
|
||||
.Sh BUGS
|
||||
Uses the onboard firmware, which is not a good way to do it.
|
||||
Doesn't support DMA or high speeds.
|
||||
Currently the driver does not support multicast.
|
||||
The timeout interval can be quite long (16 seconds) for a 512k board.

||||

.Sh HISTORY
|
||||
The
|

.Fx 2.0.5
|
||||
coming from NetBSD.
|
||||

The
|

.Nm
|
||||
device driver was written by
