62.Nm intro
63.Nd introduction to special files and hardware support
64.Sh DESCRIPTION
65The manual pages in section 4 describe the special files,
66related driver functions, and networking support
67available in the system.
68In this part of the manual, the SYNOPSIS section of
69each configurable device gives a sample specification
70for use in constructing a system description for the
71.Xr config 8
72program.
73The DIAGNOSTICS section lists messages which may appear on the console
74and/or in the system error log
75.Pa /var/log/messages
76due to errors in device operation;
77see
78.Xr syslogd 8
79for more information.
80.Pp
81This section contains both devices
82which may be configured into the system
83and network related information.
84The networking support is introduced in
85.Xr netintro 4 .
86.Sh DEVICE SUPPORT
87This section describes the hardware supported on the
88Alpha
89platform.
90Software support for these devices comes in two forms.
91A hardware device may be supported with a character or block
92.Em device driver ,
93or it may be used within the networking subsystem and have a
94.Em network interface driver .
95Block and character devices are accessed through files in the file
96system of a special type; see
97.Xr mknod 8 .
98Network interfaces are indirectly accessed through the interprocess
99communication facilities provided by the system; see
100.Xr socket 2 .
101.Pp
102A hardware device is identified to the system at configuration time
103and the appropriate device or network interface driver is then compiled
104into the system.
105When the resultant system is booted, the autoconfiguration facilities in
106the system probe for the device and, if found, enable the software support
107for it.
108If a device does not respond at autoconfiguration
109time, it is not accessible at any time afterwards.
110To enable a device which did not autoconfigure,
111the system will have to be rebooted.
112.Pp
113The autoconfiguration system is described in
114.Xr autoconf 4 .
115A list of the supported hardware and devices is given below.
116.Sh SUPPORTED SYSTEMS
117.Tn DEC
