37.Sh NAME
38.Nm intro
39.Nd introduction to special files and hardware support
40.Sh DESCRIPTION
41This section describes the special files, related driver functions,
42and networking support available in the system.
43In this part of the manual, the
44.Tn SYNOPSIS
45section of each configurable device gives a sample specification
46for use in constructing a system description for the
47.Xr config 8
48program.
49The
50.Tn DIAGNOSTICS
51section lists messages which may appear on the console
52and/or in the system error log
53.Pa /var/log/messages
54due to errors in device operation; see
55.Xr syslogd 8
56for more information.
57.Pp
58This section contains both devices which may be configured into
59the system and network related information.
60The networking support is introduced in
61.Xr netintro 4 .
62.Sh DEVICE SUPPORT
63This section describes the hardware supported by
64.Nx Ns /sgimips .
65Software support for these devices comes in two forms.
66A hardware device may be supported with a character or block
67.Em device driver ,
68or it may be used within the networking subsystem and have a
69.Em network interface driver .
70Block and character devices are accessed through files in the file
71system of a special type; see
72.Xr mknod 8 .
73Network interfaces are indirectly accessed through the interprocess
74communication facilities provided by the system; see
75.Xr socket 2 .
76.Pp
77A hardware device is identified to the system at configuration time
78and the appropriate device or network interface driver is then
79compiled into the system.
80When the resultant system is booted, the autoconfiguration facilities
81in the system probe for the device and, if found, enable the software
82support for it.
83If a device does not respond at autoconfiguration time it is not
84accessible at any time afterwards.
85To enable a device which did not autoconfigure, the system must be rebooted.
86.Pp
87The autoconfiguration system is described in
88.Xr autoconf 4 .
89A list of the supported devices is given below.
