|

.Nd introduction to pmppc special files and hardware support
|
|
.Sh DESCRIPTION
|
|
This section describes the special files, related driver functions,
|
|
and networking support available in the system.
|
|
In this part of the manual, the
|
|
.Tn SYNOPSIS
|
|
section of each configurable device gives a sample specification
|
|
for use in constructing a system description for the
|
|
.Xr config 1
|
|
program.
|
|
The
|
|
.Tn DIAGNOSTICS
|
|
section lists messages which may appear on the console
|
|
and/or in the system error log
|
|
.Pa /var/log/messages
|
|
due to errors in device operation;
|
|
see
|
|
.Xr syslogd 8
|
|
for more information.
|
|
.Pp
|
|
This section contains both devices
|
|
which may be configured into the system
|
|
and network related information.
|
|
The networking support is introduced in
|
|
.Xr netintro 4 .
|
|
.Sh PMPPC DEVICE SUPPORT
|
|
This section describes the hardware supported on the
|
|
.Tn Artesyn PM/PPC
|
|
card.
|
|
Software support for these devices comes in two forms.
|
|
A hardware device may be supported with a character or block
|
|
.Em device driver ,
|
|
or it may be used within the networking subsystem and have a
|
|
.Em network interface driver .
|
|
Block and character devices are accessed through files in the file
|
|
system of a special type; see
|
|
.Xr mknod 8 .
|
|
Network interfaces are indirectly accessed through the interprocess
|
|
communication facilities provided by the system; see
|
|
.Xr socket 2 .
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The autoconfiguration system is described in
|
|
.Xr autoconf 4 .
|
|
A list of the supported devices is given below.

.Sh LIST OF DEVICES
|
|
The devices listed below are supported in this incarnation of
|
|
the system.
