NAME
intro -- introduction to acorn32 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 specifi-
cation for use in constructing a system description for the config(1)
program. The DIAGNOSTICS section lists messages which may appear on the
console and/or in the system error log /var/log/messages due to errors in
device operation; see syslogd(8) for more information.
This section contains both devices which may be configured into the sys-
tem and network related information. The networking support is intro-
duced in netintro(4).
DEVICE SUPPORT
This section describes the hardware supported on the acorn32 (RiscPC)
platform. 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; see 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 autoconfigura-
tion time it is not accessible at any time afterwards. To enable a
device which did not autoconfigure, the system must be rebooted.
The autoconfiguration system is described in autoconf(4). A list of the
supported devices is given below.
