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 autoconf 4 , 99.Xr awacs 4 , 100.Xr config 8 101.Sh HISTORY 102The 103.Tn macppc 104.Nm intro 105man page first appeared in 106.Nx 1.5.1 , 107based on the 108.Nx Ns /mac68k 109.Xr intro 4 . 110.Sh LIST OF DEVICES 111The devices listed below are supported in this incarnation of 112the system. 113Devices are indicated by their functional interface. 114Not all supported devices are listed. 115.Pp 116PCMCIA devices are supported through the 117.Xr pcmcia 4 118bus and associated devices. 119.Pp 120Cardbus devices are supported through the 121.Xr cardbus 4 122bus and associated devices. 123.Pp 124USB devices are supported through the 125.Xr usb 4 126bus and associated devices. 127.Pp 128Additionally, the following specific devices are supported: 129.Bl -tag -width "xxxxxxxx" -compact -offset indent 130.It Em adb 131Apple Desktop Bus event interface. 132.It Em awacs 133Audio Waveform Amplifier and Converter \(em Apple Sound Chip 134(supported systems include 603 and 604 based 135machines, and 136.Tn Open Firmware 3 137based machines). 138.It Em bm 139bmac ethernet (at least in the G3 series). 140.It Em esp 141.Tn NCR 14253C9x built-in SCSI interface. 143.It Em gmac 144gmac ethernet. 145.It Em kmem 146kernel virtual memory. 147.It Em mc 148MACE ethernet. 149.It Em mem 150physical memory. 151.It Em mesh 152MESH built-in SCSI interface (most Old World machines up to the 1999 153series of G3 PowerBooks). 154.It Em nvram 155NVRAM access. 156.It Em ofb 157PCI based frame buffer with 158.Tn Open Firmware 159support. 160.It Em openfirm 161.Tn Open Firmware 162access. 163.It Em wdc 164Standard on-board IDE controller. 165.It Em zsc 166.Tn Zilog 167Z8530 built-in serial interface. 168.El 169
