A hardware 68device may be supported with a character or block 69.Em device driver , 70or it may be used within the networking subsystem and have a 71.Em network interface driver . 72Block and character devices are accessed through files in the file 73system of a special type; see 74.Xr mknod 8 . 75Network interfaces are indirectly accessed through the interprocess 76communication facilities provided by the system; see 77.Xr socket 2 . 78.Pp 79A hardware device is identified to the system at configuration time 80and the appropriate device or network interface driver is then compiled 81into the system. When the resultant system is booted, the 82autoconfiguration facilities in the system probe for the device 83and, if found, enable the software support for it. 84If a device does not respond at autoconfiguration 85time it is not accessible at any time afterwards. 86To enable a device which did not autoconfigure, 87the system will have to be rebooted. 88.Pp 89The autoconfiguration system is described in 90.Xr autoconf 4 . 91A list of the supported devices is given below. 92.Sh SEE ALSO 93.Xr config 1 , 94.Xr autoconf 4 95.Sh HISTORY 96The 97.Tn Mac68k 98.Nm intro 99man page first appeared in 100.Nx 1.3 . 101.Sh LIST OF DEVICES 102The devices listed below are supported in this incarnation of 103the system. 104Devices are indicated by their functional interface. 105Not all supported devices are listed. 106.Bl -tag -width "xxxxxx" -compact -offset indent 107.It Em adb 108Apple Desktop Bus event interface 109.It Em ae 110DP8390-based Ethernet interface 111.It Em asc 112Apple Sound Chip 113.It Em esp 114.Tn NCR 11553C9x built-in SCSI interface 116.It Em grf 117on-board and NuBus-based video interface 118.It Em kmem 119kernel virtual memory 120.It Em ite 121Mac68k Internal Terminal Emulator 122.It Em mem 123physical memory 124.It Em ncrscsi 125.Tn NCR 1265380 built-in SCSI interface 127.It Em sbc 128.Tn NCR 1295380 built-in SCSI interface 130.It Em sn 131DP83932-based Ethernet interface (SONIC) 132.It Em zsc 133.Tn Zilog 134Z8530 built-in serial interface 135.El 136
