+.Sh NAME
+.Nm intro
+.Nd introduction to 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 8
+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 DEVICE SUPPORT
+This section describes the hardware supported on the PowerPC
+platform.
+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 .
+Character and block
+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 must be rebooted.
+.Pp
+A list of the supported devices is given below.
+.Sh SEE ALSO
+.Xr config 8
+.Sh SUPPORTED SYSTEMS
+The following PowerPC models are 
+.Em supported:
+.Pp
+PowerMac G4
+.br
+PowerMac Dual G4
+.br
+PowerMac G4 Cube

+.br

+iMac DV+
+.br
+PowerBook G3 (FireWire)
+.br
+PowerBook G4
+.br
+iBook (only limited testing)
+.br
+StarMax (development in progress)
+.Pp
+The following are 
+.Em not supported:
+.Pp
+Support for older PREP style machines has been removed; lack of availability
+of the hardware and relatively slow speed compared to more recent machines has
+contributed to this decision.
+.Pp
+Apple PowerMac systems with a 601 processor or lack OpenFirmware will likely
+never be supported.
+.Pp
+At the current time, older OpenFirmware machines are not supported. This is
+mostly due to lack of developer resources to work onthe support in addition
+to limited availability of hardware.
+.Sh LIST OF DEVICES
+The devices listed below are supported in this incarnation of
+the system.  Devices are indicated by their functional interface.
+Not all supported devices are listed.
