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 HISTORY 98The 99.Tn macppc 100.Nm intro 101man page first appeared in 102.Nx 1.5.1 , 103based on the 104.Nx Ns /mac68k 105.Xr intro 4 . 106.Sh SEE ALSO 107.Xr intro 4 , 108.Xr autoconf 4 , 109.Xr awacs 4 , 110.Xr config 8 111.Sh LIST OF DEVICES 112The devices listed below are supported in this incarnation of 113the system. 114Devices are indicated by their functional interface. 115Not all supported devices are listed. 116.Pp 117PCMCIA devices are supported through the 118.Xr pcmcia 4 119bus and associated devices. 120.Pp 121Cardbus devices are supported through the 122.Xr cardbus 4 123bus and associated devices. 124.Pp 125USB devices are supported through the 126.Xr usb 4 127bus and associated devices. 128.Pp 129Additionally, the following specific devices are supported: 130.Bl -tag -width "xxxxxxxx" -compact -offset indent 131.It Em adb 132Apple Desktop Bus event interface. 133.It Em awacs 134Audio Waveform Amplifier and Converter \(em Apple Sound Chip 135(supported systems include 603 and 604 based 136machines, and 137.Tn Open Firmware 3 138based machines). 139.It Em bm 140bmac ethernet (at least in the G3 series). 141.It Em esp 142.Tn NCR 14353C9x built-in SCSI interface. 144.It Em gmac 145gmac ethernet. 146.It Em kmem 147kernel virtual memory. 148.It Em mc 149MACE ethernet. 150.It Em mem 151physical memory. 152.It Em mesh 153MESH built-in SCSI interface (most Old World machines up to the 1999 154series of G3 PowerBooks). 155.It Em nvram 156NVRAM access. 157.It Em ofb 158PCI based frame buffer with 159.Tn Open Firmware 160support. 161.It Em openfirm 162.Tn Open Firmware 163access. 164.It Em wdc 165Standard on-board IDE controller. 166.It Em zsc 167.Tn Zilog 168Z8530 built-in serial interface. 169.El 170
