A hardware 73device may be supported with a character or block 74.Em device driver , 75or it may be used within the networking subsystem and have a 76.Em network interface driver . 77Block and character devices are accessed through files in the file 78system of a special type; see 79.Xr mknod 8 . 80Network interfaces are indirectly accessed through the interprocess 81communication facilities provided by the system; see 82.Xr socket 2 . 83.Pp 84A hardware device is identified to the system at configuration time 85and the appropriate device or network interface driver is then compiled 86into the system. When the resultant system is booted, the 87autoconfiguration facilities in the system probe for the device 88and, if found, enable the software support for it. 89If a device does not respond at autoconfiguration 90time it is not accessible at any time afterwards. 91To enable a device which did not autoconfigure, 92the system will have to be rebooted. 93.Pp 94The autoconfiguration system is described in 95.Xr autoconf 4 . 96A list of the supported devices is given below. 97.Sh SEE ALSO 98.Xr config 1 , 99.Xr autoconf 4 , 100.Xr awacs 4 , 101.Xr bm 4 , 102.Xr gem 4 , 103.Xr mc 4 , 104.Xr tlp 4 105.Sh HISTORY 106The 107.Tn macppc 108.Nm intro 109man page first appeared in 110.Nx 1.5.1 , 111based on the 112.Nx Ns /mac68k 113.Xr intro 4 . 114.Sh LIST OF DEVICES 115The devices listed below are supported in this incarnation of 116the system. 117Devices are indicated by their functional interface. 118Not all supported devices are listed. 119.Pp 120PCMCIA devices are supported through the 121.Xr pcmcia 4 122bus and associated devices. 123.Pp 124Cardbus devices are supported through the 125.Xr cardbus 4 126bus and associated devices. 127.Pp 128USB devices are supported through the 129.Xr usb 4 130bus and associated devices. 131.Pp 132Additionally, the following specific devices are supported: 133.Bl -tag -width "xxxxxxxx" -compact -offset indent 134.It Em adb 135Apple Desktop Bus event interface. 136.It Em awacs 137Audio Waveform Amplifier and Converter \(em Apple Sound Chip 138(supported systems include 603 and 604 based 139machines, and 140.Tn Open Firmware 3 141based machines). 142.It Em bm 143BMac Ethernet. 144.It Em de 145DECchip 21x4x based Ethernet cards (see also 146.Xr tlp 4 ) . 147.It Em esp 148.Tn NCR 14953C9x built-in SCSI interface. 150.It Em gm 151GMac Ethernet. 152.It Em kmem 153kernel virtual memory. 154.It Em mc 155MACE Ethernet. 156.It Em mem 157physical memory. 158.It Em mesh 159MESH built-in SCSI interface (most Old World machines up to the 1999 160series of G3 PowerBooks). 161.It Em nvram 162NVRAM access. 163.It Em ofb 164PCI based frame buffer with 165.Tn Open Firmware 166support. 167.It Em openfirm 168.Tn Open Firmware 169access. 170.It Em tlp 171DECchip 21x4x based Ethernet cards. 172.It Em wdc 173Standard on-board IDE controller. 174.It Em zsc 175.Tn Zilog 176Z8530 built-in serial interface. 177.El 178
