36.Nm intro
37.Nd introduction to mac68k special files and hardware support
38.Sh DESCRIPTION
39This section describes the special files, related driver functions,
40and networking support
41available in the system.
42In this part of the manual, the
43.Tn SYNOPSIS
44section of
45each configurable device gives a sample specification
46for use in constructing a system description for the
47.Xr config 1
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;
55see
56.Xr syslogd 8
57for more information.
58.Pp
59This section contains both devices
60which may be configured into the system
61and network related information.
62The networking support is introduced in
63.Xr netintro 4 .
64.Sh MAC68K DEVICE SUPPORT
65This section describes the hardware supported on the
66.Tn Mac .
67Software support for these devices comes in two forms.  A hardware
68device may be supported with a character or block
69.Em device driver ,
70or it may be used within the networking subsystem and have a
71.Em network interface driver .
72Block and character devices are accessed through files in the file
73system of a special type; see
74.Xr mknod 8 .
75Network interfaces are indirectly accessed through the interprocess
76communication facilities provided by the system; see
77.Xr socket 2 .
78.Pp
79A hardware device is identified to the system at configuration time
80and the appropriate device or network interface driver is then compiled
81into the system.  When the resultant system is booted, the
82autoconfiguration facilities in the system probe for the device
83and, if found, enable the software support for it.
84If a device does not respond at autoconfiguration
85time it is not accessible at any time afterwards.
86To enable a device which did not autoconfigure,
87the system will have to be rebooted.
88.Pp
89The autoconfiguration system is described in
90.Xr autoconf 4 .
91A list of the supported devices is given below.
