35 .Nd introduction to dreamcast special files and hardware support
37 This section describes the special files, related driver functions,
38 and networking support
39 available in the system.
40 In this part of the manual, the
42 section of each configurable device gives a sample specification
43 for use in constructing a system description for the
48 section lists messages which may appear on the console
49 and/or in the system error log
51 due to errors in device operation;
56 This section contains both devices which may be configured into
57 the system and network related information.
58 The networking support is introduced in
61 This section describes the hardware supported on the
64 Software support for these devices come in two forms.
65 A hardware device may be supported with a character or block
67 or it may be used within the networking subsystem and have a
68 .Em network interface driver .
69 Block and character devices are accessed through files in the file
70 system of a special type; see
72 Network interfaces are indirectly accessed through the interprocess
73 communication facilities provided by the system; see
76 A hardware device is identified to the system at configuration time
77 and the appropriate device or network interface driver is then
78 compiled into the system.
79 When the resultant system is booted, the autoconfiguration facilities
80 in the system probe for the device and, if found, enable the software
82 If a device does not respond at autoconfiguration time, it is not
83 accessible at any time afterwards.
84 To enable a device which did not autoconfigure,
85 the system must be rebooted.
87 The autoconfiguration system is described in
89 A list of the supported devices is given below.
91 The devices listed below are supported in this incarnation of
93 Devices are indicated by their functional interface.
94 Not all supported devices are listed.
97 Standard builtin devices:
98 .Bl -tag -width gapspci -offset indent -compact
104 bridge used in expansion port peripherals
106 Builtin GD-ROM optical disc drive
108 Framebuffer device using the builtin NEC PVR graphics subsystem
110 Builtin AICA sound system
114 Controller port peripherals are supported though the
116 bus and associated device drivers.
