.Sh NAME

.Nm neptune
|
|
.Nd Neptune-X ISA bridge driver
|
|
.Sh SYNOPSIS
|
|
.Cd "neptune0 at intio0 addr 0xece000 irq 239"
|
|
.Cd "ne0 at neptune? addr 0x300"
|
|
.Sh DESCRIPTION
|
|
The Neptune-X is a Ethernet interface card initially designed by
|
|
Hirofumi Shimada, which utilizes popular NE2000 or its clone with its
|
|
own x68k-proprietary bus to ISA bus bridge.
|
|
.Pp
|
|
The
|
|
.Nx
|
|
.Nm
|
|
driver takes charge of the ISA bridge part of the Neptune-X.
|
|
It is implemented as a more generic `bus' with its own
|
|
.Xr bus_space 9
|
|
interface, and is intended to be used with
|
|
.Xr ne 4
|
|
driver.

|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device appeared in
|
|
.Nx 1.4 .
|
|
.Sh BUGS
|
|
.Nm
|
|
itself is always detected when it is specified in the kernel config file.
|
|
This is because the Neptune-X ISA bridge is transparent to software.
|
|
The attached device is detected appropriately.
