INTRO(4)

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).

ARCHIMEDES DEVICE SUPPORT
This section describes the hardware supported on the Acorn Archimedes. 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.

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. (Beware, however, that we promise the software works ONLY with the hardware indicated on the appropriate manual page.) Occasionally, new devices of a similar type may be added simply by creating appropriate table entries in the driver.

cmos	cmos ram access
cent	centronics parallel interface
fdc	floppy disc driver
lbp	cannon CX-8 laser printer driver
serial	serial line driver
st	st506 winchester disc driver
vc	video console/keyboard/mouse driver
