C 7 NAME
intro - introduction to special files and hardware support
DESCRIPTION
This section describes the special files, related driver functions,
and networking support
available in the system.
In this part of the manual, the SYNOPSIS section of
each configurable device gives a sample specification
for use in constructing a system description for the
config (8) program.
The DIAGNOSTICS section lists messages which may appear on the console
and/
or in the system error log
/usr/adm/messages due to errors in device operation;
see
syslogd (8) for more information.
This section contains both devices
which may be configured into the system, ``4'' entries,
and network related information,
``4N'', ``4P'', and ``4F'' entries;
The networking support is introduced in
intro (4N).
"HP DEVICE SUPPORT"
This section describes the hardware supported on the HP 9000/300 series.
Software support for these devices comes in two forms. A hardware
device may be supported with a character or block
"device driver" , or it may be used within the networking subsystem and have a
"network interface driver" . Block and character devices are accessed through files in the file
system of a special type; c.f.
mknod (8). Network interfaces are indirectly accessed through the interprocess
communication facilities provided by the system; see
socket (2).
A hardware device is identified to the system at configuration time
and the appropriate device or network interface driver is then compiled
into the system. When the resultant system is booted, the
autoconfiguration facilities in the system probe for the device
and, if found, enable the software support for it.
If a device does not respond at autoconfiguration
time it is not accessible at any time afterwards.
To enable a device which did not autoconfigure,
the system will have to be rebooted.
The autoconfiguration system is described in
autoconf (4). A list of the supported devices is given below.

"LIST OF DEVICES"
The devices listed below are supported in this incarnation of
the system. Pseudo-devices are not listed.
Devices are indicated by their functional interface.
Occasionally, new devices of a similar type may be added
simply by creating appropriate table entries in the driver;
e.g. new CS/80 drives.
ct 7946/9144 CS/80 cartridge tape
dca 98644 built-in serial interface
dma 98620B DMA controller
grf/ite Topcat/Gatorbox/Renaissance frame buffer
hil HIL interface
hpib Built-in and 98625 HP-IB interface
le 98643 Lance-based ethernet interface
ppi HP-IB printer/plotter interface
rd CS/80 disk interface
