A hardware 65device may be supported with a character or block 66.Em device driver , 67or it may be used within the networking subsystem and have a 68.Em network interface driver . 69Block and character devices are accessed through files in the file 70system of a special type; see 71.Xr physio 4 72and 73.Xr mknod 8 . 74Network interfaces are indirectly accessed through the interprocess 75communication facilities provided by the system; see 76.Xr socket 2 . 77.Pp 78A hardware device is identified to the system at configuration time 79and the appropriate device or network interface driver is then compiled 80into the system. When the resultant system is booted, the 81autoconfiguration facilities in the system probe for the device 82on either the 83.Tn UNIBUS 84(or 85.Tn Q-bus ) 86or 87.Tn MASSBUS 88and, if found, enable the software 89support for it. If a 90.Tn UNIBUS 91device does not respond at autoconfiguration 92time it is not accessible at any time afterwards. To 93enable a 94.Tn UNIBUS 95device which did not autoconfigure, the system will have to 96be rebooted. If a 97.Tn MASSBUS 98device comes 99.Dq on-line 100after the autoconfiguration sequence 101it will be dynamically autoconfigured into the running system. 102.Pp 103The autoconfiguration system is described in 104.Xr autoconf 4 . 105A list of the supported devices is given below. 106.Sh SEE ALSO 107.Xr intro 4 , 108.Xr netintro 4 , 109.Xr autoconf 4 , 110.Xr config 8 . 111.Rs 112.%T "Building 4.3 BSD UNIX Systems with Config" 113.%B SMM 114.%N 2 115.Re 116.Sh LIST OF DEVICES 117The devices listed below are supported in this incarnation of 118the system.
