37 .Nd introduction to sun2 special files and hardware support
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
45 each configurable device gives a sample specification
46 for use in constructing a system description for the
51 section lists messages which may appear on the console
52 and/or in the system error log
54 due to errors in device operation;
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
65 This section describes the hardware supported on the Sun2
67 Software support for these devices comes in two forms. A hardware
68 device may be supported with a character or block
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
75 Network interfaces are indirectly accessed through the interprocess
76 communication facilities provided by the system; see
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.
89 The autoconfiguration system is described in
91 A list of the supported devices is given below.
100 The following Sun2 system architectures and models are supported:
101 .Bl -tag -width eeprom
103 Sun2 systems: (MC68010)
105 Sun 2/120, 2/170 (10 MHz)
109 The devices listed below are supported in this incarnation of
110 the system. Devices are indicated by their functional interface.
111 Not all supported devices are listed.
113 .Bl -tag -width eeprom
115 black and white obio frame buffer
117 Intel 82586 Ethernet controller (Sun 2/120, 2/170)
119 3Com 3c400 Multibus Ethernet controller (Sun 2/120, 2/170)
121 Sun type 2, type 3, type 4, and type 5 keyboards (on zstty)
125 Sun "SCSI-2" Multibus SCSI controller
127 Zilog 8530 serial controller
