.Sh NAME
.Nm intro
.Nd introduction to sgimips special files and hardware support
.Sh DESCRIPTION
This section describes the special files, related driver functions,
and networking support available in the system.
In this part of the manual, the
.Tn SYNOPSIS
section of each configurable device gives a sample specification
for use in constructing a system description for the
.Xr config 1
program.
The
.Tn DIAGNOSTICS
section lists messages which may appear on the console
and/or in the system error log
.Pa /var/log/messages
due to errors in device operation; see
.Xr syslogd 8
for more information.
.Pp
This section contains both devices which may be configured into
the system and network related information.
The networking support is introduced in
.Xr netintro 4 .
.Sh DEVICE SUPPORT
This section describes the hardware supported by
.Nx Ns /sgimips .
Software support for these devices comes in two forms.
A hardware device may be supported with a character or block
.Em device driver ,
or it may be used within the networking subsystem and have a
.Em network interface driver .
Block and character devices are accessed through files in the file
system of a special type; see
.Xr mknod 8 .
Network interfaces are indirectly accessed through the interprocess
communication facilities provided by the system; see
.Xr socket 2 .
.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.
.Pp
The autoconfiguration system is described in
.Xr autoconf 4 .
A list of the supported devices is given below.
