+.Sh NAME
+.Nm intro
+.Nd introduction to sparc64 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 DEVICE SUPPORT
+This section describes the hardware supported on the SPARC64
+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 .
+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 must be rebooted.
+.Pp
+The autoconfiguration system is described in
+.Xr autoconf 4 .
+A list of the supported devices is given below.
