A hardware 72device may be supported with a character or block 73.Em device driver , 74or it may be used within the networking subsystem and have a 75.Em network interface driver . 76Block and character devices are accessed through files in the file 77system of a special type; see 78.Xr mknod 8 . 79Network interfaces are indirectly accessed through the interprocess 80communication facilities provided by the system; see 81.Xr socket 2 . 82.Pp 83A hardware device is identified to the system at configuration time 84and the appropriate device or network interface driver is then compiled 85into the system. When the resultant system is booted, the 86autoconfiguration facilities in the system probe for the device 87and, if found, enable the software support for it. 88If a device does not respond at autoconfiguration 89time it is not accessible at any time afterwards. 90To enable a device which did not autoconfigure, 91the system will have to be rebooted. 92.Pp 93The autoconfiguration system is described in 94.Xr autoconf 4 . 95A list of the supported devices is given below. 96.Sh SEE ALSO 97.Xr autoconf 4 , 98.Xr config 8 99.Sh HISTORY 100The 101.Tn Mac68k 102.Nm intro 103man page first appeared in 104.Nx 1.3 . 105.Sh LIST OF DEVICES 106The devices listed below are supported in this incarnation of 107the system. 108Devices are indicated by their functional interface. 109Not all supported devices are listed. 110.Bl -tag -width "xxxxxx" -compact -offset indent 111.It Em adb 112Apple Desktop Bus event interface 113.It Em ae 114DP8390-based Ethernet interface 115.It Em asc 116Apple Sound Chip 117.It Em esp 118.Tn NCR 11953C9x built-in SCSI interface 120.It Em grf 121on-board and NuBus-based video interface 122.It Em kmem 123kernel virtual memory 124.It Em ite 125Mac68k Internal Terminal Emulator 126.It Em mem 127physical memory 128.It Em ncrscsi 129.Tn NCR 1305380 built-in SCSI interface 131.It Em sbc 132.Tn NCR 1335380 built-in SCSI interface 134.It Em sn 135DP83932-based Ethernet interface (SONIC) 136.It Em zsc 137.Tn Zilog 138Z8530 built-in serial interface 139.El 140
