A hardware 45device may be supported with a character or block 46.Em device driver , 47or it may be used within the networking subsystem and have a 48.Em network interface driver . 49Block and character devices are accessed through files in the file 50system of a special type; see 51.Xr mknod 8 . 52Network interfaces are indirectly accessed through the interprocess 53communication facilities provided by the system; see 54.Xr socket 2 . 55.Pp 56A hardware device is identified to the system at configuration time 57and the appropriate device or network interface driver is then compiled 58into the system. When the resultant system is booted, the 59autoconfiguration facilities in the system probe for the device 60and, if found, enable the software support for it. 61If a device does not respond at autoconfiguration 62time it is not accessible at any time afterwards. 63To enable a device which did not autoconfigure, 64the system will have to be rebooted. 65.Pp 66The autoconfiguration system is described in 67.Xr autoconf 4 . 68A list of the supported devices is given below. 69.Sh SEE ALSO 70.Xr intro 4 , 71.Xr intro 4 , 72.Xr autoconf 4 , 73.Xr config 8 . 74.Rs 75.%T "Building 4.3 BSD UNIX Systems with Config (SMM:2)" 76.Re 77.Sh LIST OF DEVICES 78The devices listed below are supported in this incarnation of 79the system. Pseudo-devices are not listed. 80Devices are indicated by their functional interface. 81Occasionally, new devices of a similar type may be added 82simply by creating appropriate table entries in the driver; 83for example, new 84.Tn CS/80 85drives. 86.Bl -column grf/ite -offset indent 87ct 7946/9144 CS/80 cartridge tape 88dca 98644 built-in serial interface 89dcl HP 98628A communications link 90dcm HP 98642A communications multiplexer 91dma 98620B DMA controller 92dv HP98730 ``DaVinci'' device interface 93gb HP98700 ``Gatorbox'' device interface 94grf/ite Topcat/Gatorbox/Renaissance frame buffer 95hil HIL interface 96hpib Built-in and 98625 HP-IB interface 97ite HP Internal Terminal Emulator 98le 98643 Lance-based ethernet interface 99mem main memory 100ppi HP-IB printer/plotter interface 101rb HP98720 ``Renaissance'' device interface 102rd CS/80 disk interface 103rmp HP Remote Maintenance Protocol family 104st CCS SCSI tape drive 105tc HP98544-98550 ``Topcat'' and ``Catseye'' device interface 106.El 107.Sh HISTORY 108The 109.Tn HP300 110.Nm intro 111appeared in 112.Bx 4.3 Reno . 113
