NEPTUNE(4)           NetBSD/x68k Kernel Interfaces Manual           NEPTUNE(4)

NAME
     neptune -- Neptune-X ISA bridge driver

SYNOPSIS
     neptune0 at intio0 addr 0xece000 irq 239
     ne0 at neptune? addr 0x300

DESCRIPTION
     The Neptune-X is a Ethernet interface card initially designed by Hirofumi
     Shimada, which uses popular NE2000 or its clone with its own x68k-propri-
     etary bus to ISA bus bridge.

     The NetBSD neptune driver takes charge of the ISA bridge part of the Nep-
     tune-X.  It is implemented as a more generic `bus' with its own
     bus_space(9) interface, and is intended to be used with ne(4) driver.

SEE ALSO
     intro(4), isa(4), ne(4), bus_space(9)

HISTORY
     The neptune device appeared in NetBSD 1.4.

BUGS
     neptune itself is always detected when it is specified in the kernel con-
     fig file.  This is because the Neptune-X ISA bridge is transparent to
     software.  The attached device is detected appropriately.
