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 specifi-
cation 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 /var/log/messages due to errors in
device operation; see syslogd(8) for more information.
ISA and EISA DEVICE SUPPORT
This section describes the hardware supported on ISA and EISA bus comput-
ers using the Intel 386, 486, or Pentium. Software support for these de-
vices 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 de-
vices are accessed through files in the file system of a special type;
see mknod(8). Network interfaces are indirectly accessed through the in-
terprocess 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 de-
vice 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.
