A hardware 63device may be supported with a character or block 64.Em device driver , 65or it may be used within the networking subsystem and have a 66.Em network interface driver . 67Block and character devices are accessed through files in the file 68system of a special type; see 69.Xr physio 4 70and 71.Xr mknod 8 . 72Network interfaces are indirectly accessed through the interprocess 73communication facilities provided by the system; see 74.Xr socket 2 . 75.Pp 76A hardware device is identified to the system at configuration time 77and the appropriate device or network interface driver is then compiled 78into the system. When the resultant system is booted, the 79autoconfiguration facilities in the system probe for the device 80on either the 81.Tn UNIBUS 82(or 83.Tn Q-bus ) 84or 85.Tn MASSBUS 86and, if found, enable the software 87support for it. If a 88.Tn UNIBUS 89device does not respond at autoconfiguration 90time it is not accessible at any time afterwards. To 91enable a 92.Tn UNIBUS 93device which did not autoconfigure, the system will have to 94be rebooted. If a 95.Tn MASSBUS 96device comes 97.Dq on-line 98after the autoconfiguration sequence 99it will be dynamically autoconfigured into the running system. 100.Pp 101The autoconfiguration system is described in 102.Xr autoconf 4 . 103A list of the supported devices is given below. 104.Sh SEE ALSO 105.Xr autoconf 4 , 106.Xr netintro 4 , 107.Xr config 8 108.Rs 109.%T "Building 4.3 BSD UNIX Systems with Config" 110.%B SMM 111.%N 2 112.Re 113.Sh LIST OF DEVICES 114The devices listed below are supported in this incarnation of 115the system. Pseudo-devices are not listed. 116Devices are indicated by their functional interface. 117If second vendor products provide functionally identical interfaces 118they should be usable with the supplied software. 119.Bf -symbolic 120Beware, 121however, that we promise the software works 122ONLY with the hardware indicated on the appropriate manual page. 123.Ef 124Occasionally, new devices of a similar type may be added 125simply by creating appropriate table entries in the driver. 126.Pp 127.Bl -column tmscp -offset indent 128acc ACC LH/DH IMP communications interface 129ad Data translation A/D interface 130css DEC IMP-11A communications interface 131crl VAX-8600, 8650 console RL02 disk 132ct C/A/T or APS phototypesetter 133ddn ACC ACP625 DDN Standard Mode X.25 IMP interface 134de DEC DEUNA 10Mb/s Ethernet controller 135dh DH-11 emulators, terminal multiplexor 136dhu DHU-11 terminal multiplexor 137dmc DEC DMC-11/DMR-11 point-to-point communications device 138dmf DEC DMF-32 terminal multiplexor and parallel printer interface 139dmz DEC DMZ-32 terminal multiplexor 140dn DEC DN-11 autodialer interface 141dz DZ-11 terminal multiplexor 142ec 3Com 10Mb/s Ethernet controller 143en Xerox 3Mb/s Ethernet controller (obsolete) 144ex Excelan 10Mb/s Ethernet controller 145fl VAX-11/780 console floppy interface 146hdh ACC IF-11/HDH IMP interface 147hk RK6-11/RK06 and RK07 moving head disk 148hp MASSBUS disk interface (with RP06, RM03, RM05, etc.) 149ht TM03 MASSBUS tape drive interface (with TE-16, TU-45, TU-77) 150hy DR-11B or GI-13 interface to an NSC Hyperchannel 151ik Ikonas frame buffer graphics device interface 152il Interlan 1010, 1010A 10Mb/s Ethernet controller 153ix Interlan NP-100 10Mb/s Ethernet controller 154kg KL-11/DL-11W line clock 155lp LP-11 parallel line printer interface 156mt TM78 MASSBUS tape drive interface 157np Interlan NP-100 10Mb/s Ethernet controller (intelligent mode) 158pcl DEC PCL-11 communications interface 159ps Evans and Sutherland Picture System 2 graphics interface 160qe DEC DEQNA Q-bus 10 Mb/s Ethernet interface 161rx DEC RX02 floppy interface 162tm TM-11/TE-10 tape drive interface 163tmscp TMSCP-compatible tape controllers (e.g., TU81, TK50) 164ts TS-11 tape drive interface 165tu VAX-11/730 TU-58 console cassette interface 166uda DEC UDA-50 disk controller 167un DR-11W interface to Ungermann-Bass 168up Emulex SC-21V, SC-31 UNIBUS disk controller 169ut UNIBUS TU-45 tape drive interface 170uu TU-58 dual cassette drive interface (DL-11) 171va Benson-Varian printer/plotter interface 172vp Versatec printer/plotter interface 173vv Proteon proNET 10Mb/s and 80Mb/s ring network interface 174.El 175.Sh HISTORY 176The section 4 177.Nm intro 178appeared in 179.Bx 4.1 . 180
