NAME    [Toc]    [Back]

     sn - Ethernet driver for SONIC-based Ethernet adapters

SYNOPSIS    [Toc]    [Back]

     sn* at obio?
     sn* at nubus?

DESCRIPTION    [Toc]    [Back]

     The sn interface provides access to a 10 Mb/s Ethernet  network via the
     National Semiconductor DP83932 (SONIC) Ethernet chip set.

     Each  of  the  host's network addresses is specified at boot
time with an
     SIOCSIFADDR ioctl(2).  The sn interface employs the  address
resolution
     protocol  described in arp(4) to dynamically map between Internet and Ethernet
 addresses on the local network.

HARDWARE    [Toc]    [Back]

     The sn interface is currently known to support the following
NuBus cards:

           Cayman Gatorcard PDS
           Dayna DaynaPort/E30

     In addition, the sn interface supports on-board Ethernet for
500-series
     PowerBooks and non-AV Quadras.
