9: .SH NAME
10: intro \- introduction to special files and hardware support
11: .SH DESCRIPTION
12: This section describes the special files, related driver functions,
13: and networking support
14: available in the system.
15: In this part of the manual, the SYNOPSIS section of
16: each configurable device gives a sample specification
17: for use in constructing a system description for the
18: .IR config (8)
19: program.
20: The DIAGNOSTICS section lists messages which may appear on the console
21: and/or in the system error log
22: .I /usr/adm/messages
23: due to errors in device operation;
24: see
25: .IR syslogd (8)
26: for more information.
27: .PP
28: This section contains both devices
29: which may be configured into the system, ``4'' entries,
30: and network related information,
31: ``4N'', ``4P'', and ``4F'' entries;
32: The networking support is introduced in
33: .IR intro (4N).
34: .SH "HP DEVICE SUPPORT"
35: This section describes the hardware supported on the HP 9000/300 series.
36: Software support for these devices comes in two forms. A hardware
37: device may be supported with a character or block
38: .IR "device driver" ,
39: or it may be used within the networking subsystem and have a
40: .IR "network interface driver" .
41: Block and character devices are accessed through files in the file
42: system of a special type; c.f.
43: .IR mknod (8).
44: Network interfaces are indirectly accessed through the interprocess
45: communication facilities provided by the system; see
46: .IR socket (2).
47: .PP
48: A hardware device is identified to the system at configuration time
49: and the appropriate device or network interface driver is then compiled
50: into the system. When the resultant system is booted, the
51: autoconfiguration facilities in the system probe for the device
52: and, if found, enable the software support for it.
53: If a device does not respond at autoconfiguration
54: time it is not accessible at any time afterwards.
55: To enable a device which did not autoconfigure,
56: the system will have to be rebooted.
57: .PP
58: The autoconfiguration system is described in
59: .IR autoconf (4).
60: A list of the supported devices is given below.

68: .SH "LIST OF DEVICES"
69: The devices listed below are supported in this incarnation of
70: the system. Pseudo-devices are not listed.
71: Devices are indicated by their functional interface.
72: Occasionally, new devices of a similar type may be added
73: simply by creating appropriate table entries in the driver;
74: e.g. new CS/80 drives.
