38.Dt INTRO 4 atari
39.Os
40.Sh NAME
41.Nm intro
42.Nd introduction to atari special files and hardware support
43.Sh DESCRIPTION
44This section describes the special files, related driver functions,
45and networking support
46available in the system.
47In this part of the manual, the
48.Sx SYNOPSIS
49section of
50each configurable device gives a sample specification
51for use in constructing a system description for the
52.Xr config 1
53program.
54The
55.Tn DIAGNOSTICS
56section lists messages which may appear on the console
57and/or in the system error log
58.Pa /var/log/messages
59due to errors in device operation;
60see
61.Xr syslogd 8
62for more information.
63.Pp
64This section contains both devices
65which may be configured into the system
66and network related information.
67The networking support is introduced in
68.Xr netintro 4 .
69.Sh LIST OF PLATFORMS SUPPORTED
70Platforms supported by the atari port:
71.Bl -tag -width Falcon -offset indent -compact
72.It TT030
73A standard TT030 model with at least 4Mb of RAM.
74.It Falcon
75A standard Falcon with at least 4Mb of RAM. An FPU is not required as the
76default kernels include FP-emulation support.
77.It Hades
78A standard Hades with either an 040 or 060 processor and at least 8 Mb of RAM.
79.El
80.Sh DEVICE SUPPORT
81This section describes the hardware supported on the atari
82(atari-clone) platform.
83Software support for these devices comes in two forms.  A hardware
84device may be supported with a character or block
85.Em device driver ,
86or it may be used within the networking subsystem and have a
87.Em network interface driver .
88Block and character devices are accessed through files in the file
89system of a special type; see
90.Xr mknod 8 .
91Network interfaces are indirectly accessed through the interprocess
92communication facilities provided by the system; see
93.Xr socket 2 .
94.Pp
95A hardware device is identified to the system at configuration time
96and the appropriate device or network interface driver is then compiled
97into the system.  When the resultant system is booted, the
98autoconfiguration facilities in the system probe for the device
99and, if found, enable the software support for it.
100If a device does not respond at autoconfiguration
101time it is not accessible at any time afterwards.
102To enable a device which did not autoconfigure,
103the system must be rebooted.
104.Pp
105The autoconfiguration system is described in
106.Xr autoconf 4 .
107A list of the supported devices is given below.
108.Sh LIST OF DEVICES
109The devices listed below are supported in this incarnation of
110the system.  Devices are indicated by their functional interface.
111Not all supported devices are listed, not all devices exist on all models.
112.Pp
