<p class="Pp">This section describes the special files, related driver
functions, and networking support available in the system. In this part of
the manual, the <a class="Sx" href="#SYNOPSIS">SYNOPSIS</a> section of each
configurable device gives a sample specification for use in constructing a
system description for the <a class="Xr">config(1)</a> program. The
DIAGNOSTICS section lists messages which may appear on the console and/or in
the system error log <span class="Pa">/var/log/messages</span> due to errors
in device operation; see <a class="Xr">syslogd(8)</a> for more
information.</p>
<p class="Pp">This section contains both devices which may be configured into
the system and network related information. The networking support is
introduced in <a class="Xr">netintro(4)</a>.</p>

<h1 class="Sh" id="DEVICE_SUPPORT"><a class="permalink" href="#DEVICE_SUPPORT">DEVICE
SUPPORT</a></h1>
<p class="Pp">This section describes the hardware supported on the atari
(atari-clone) platform. Software support for these devices comes in two
forms. A hardware device may be supported with a character or block
<a class="permalink" href="#device"><i class="Em" id="device">device
driver</i></a>, or it may be used within the networking subsystem and have a
<a class="permalink" href="#network"><i class="Em" id="network">network
interface driver</i></a>. Block and character devices are accessed through
files in the file system of a special type; see <a class="Xr">mknod(8)</a>.
Network interfaces are indirectly accessed through the interprocess
communication facilities provided by the system; see
<a class="Xr">socket(2)</a>.</p>
<p class="Pp">A hardware device is identified to the system at configuration
time and the appropriate device or network interface driver is then compiled
into the system. When the resultant system is booted, the autoconfiguration
facilities in the system probe for the device and, if found, enable the
software support for it. If a device does not respond at autoconfiguration
time it is not accessible at any time afterwards. To enable a device which
did not autoconfigure, the system must be rebooted.</p>
<p class="Pp">The autoconfiguration system is described in
<a class="Xr">autoconf(4)</a>. A list of the supported devices is given
below.</p>
