.Sh NAME
.Nm mc
.Nd Am79C940 (MACE) on-board Ethernet device
.Sh SYNOPSIS
.Cd "mc* at macobio?"
.Sh DESCRIPTION
The
.Nm
interface provides access to a 10 Mb/s Ethernet network via the AMD Am79C940
(MACE) Ethernet chip set.
.Pp
Each of the host's network addresses is specified at boot time with a
.Dv SIOCSIFADDR
.Xr ioctl 2 .
The
.Nm
interface employs the address resolution protocol described in
.Xr arp 4
to dynamically map between Internet and Ethernet addresses on the
local network.
.Pp
The
.Nm
interface supports the on-board Ethernet of most old world
Power Macintosh systems.
