<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 SYNOPSIS 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>
</section>
<section class="Sh">
<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 pmax
(MIPS-based DECstation/DECsystem) 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">pmax/autoconf(4)</a>. A list of the supported devices is given
below.</p>

<div class="Bd-indent">
<dl class="Bl-tag Bl-compact">
<dt>DECstation 2100 and 3100</dt>
<dd>also known as "PMIN" and "PMAX". The 2100 and 3100

<dt>DECsystem 5100</dt>
<dd>also known as "MIPSMATE".</dd>
<dt>DECstation 5000/200</dt>
<dd>also known as "3MAX". The 5000/200 has a 25 MHz R3000 and is the
first-generation TURBOchannel platform.</dd>
<dt>DECstation 5000/1xx</dt>
<dd>also known as "3MIN" or "kmin". The 5000/1xx comes in
20 MHz, 25 MHz, and 33 MHz versions and is numbered appropriately. Two
12.5 MHz TURBOchannel slots are provided.</dd>
<dt>DECstation 5000/xx</dt>
<dd>also known as "Personal DECstation" or "MAXINE". The
5000/xx comes in 20 MHz, 25 MHz, and 33 MHz variants. A baseboard 1024x786
framebuffer, and two 12.5 MHz TURBOchannel slots are provided.</dd>
<dt>DECstation 5000/240 and DECsystem 5900</dt>
<dd>also known as "3MAXPLUS". These systems have a 40 MHz R3400 CPU
and three 25 MHz TURBOchannel slots. The 5900 is an expanded-cabinet
version of the 5000/240.</dd>
</dl>
</div>
<p class="Pp">TURBOchannel systems (except the 5000/200) can be upgraded to an
R4000 or R4400 CPU by upgrading the CPU daughterboard.</p>
