36 .Nm intro
37 .Nd introduction to sun3 special files and hardware support
38 .Sh DESCRIPTION
39 This section describes the special files, related driver functions,
40 and networking support
41 available in the system.
42 In this part of the manual, the
43 .Tn SYNOPSIS
44 section of
45 each configurable device gives a sample specification
46 for use in constructing a system description for the
47 .Xr config 1
48 program.
49 The
50 .Tn DIAGNOSTICS
51 section lists messages which may appear on the console
52 and/or in the system error log
53 .Pa /var/log/messages
54 due to errors in device operation;
55 see
56 .Xr syslogd 8
57 for more information.
58 .Pp
59 This section contains both devices
60 which may be configured into the system
61 and network related information.
62 The networking support is introduced in
63 .Xr netintro 4 .
64 .Sh DEVICE SUPPORT
65 This section describes the hardware supported on the Sun3
66 platform.
67 Software support for these devices comes in two forms. A hardware
68 device may be supported with a character or block
69 .Em device driver ,
70 or it may be used within the networking subsystem and have a
71 .Em network interface driver .
72 Block and character devices are accessed through files in the file
73 system of a special type; see
74 .Xr mknod 8 .
75 Network interfaces are indirectly accessed through the interprocess
76 communication facilities provided by the system; see
77 .Xr socket 2 .
78 .Pp
79 A hardware device is identified to the system at configuration time
80 and the appropriate device or network interface driver is then compiled
81 into the system. When the resultant system is booted, the
82 autoconfiguration facilities in the system probe for the device
83 and, if found, enable the software support for it.
84 If a device does not respond at autoconfiguration
85 time it is not accessible at any time afterwards.
86 To enable a device which did not autoconfigure,
87 the system must be rebooted.
88 .Pp
89 The autoconfiguration system is described in
90 .Xr autoconf 4 .
91 A list of the supported devices is given below.
