60 .Nd introduction to x68k special files and hardware support
62 This section describes the special files, related driver functions,
63 and networking support
64 available in the system.
65 In this part of the manual, the
68 each configurable device gives a sample specification
69 for use in constructing a system description for the
74 section lists messages which may appear on the console
75 and/or in the system error log
77 due to errors in device operation;
82 This section contains both devices
83 which may be configured into the system
84 and network related information.
85 The networking support is introduced in
87 .Sh X68k DEVICE SUPPORT
88 This section describes the hardware supported on the
91 Software support for these devices comes in two forms. A hardware
92 device may be supported with a character or block
94 or it may be used within the networking subsystem and have a
95 .Em network interface driver .
96 Block and character devices are accessed through files in the file
97 system of a special type; see
99 Network interfaces are indirectly accessed through the interprocess
100 communication facilities provided by the system; see
103 A hardware device is identified to the system at configuration time
104 and the appropriate device or network interface driver is then compiled
105 into the system. When the resultant system is booted, the
106 autoconfiguration facilities in the system probe for the device
107 and, if found, enable the software support for it.
108 If a device does not respond at autoconfiguration
109 time it is not accessible at any time afterwards.
110 To enable a device which did not autoconfigure,
111 the system will have to be rebooted.
113 The autoconfiguration system is described in
115 A list of the supported devices is given below.
124 The devices listed below are supported in this incarnation of
