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 must 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 autoconf 4 , 94.Xr config 8 95.Sh LIST OF DEVICES 96The devices listed below are supported in this incarnation of 97the system.
