NAME
intro - introduction to special files and hardware support
DESCRIPTION
This section describes the special files, related driver functions, and networking support available in the system. In this part of the manual, the SYNOPSIS section of each configurable device gives a sample specifi- cation for use in constructing a system description for the /sys/conf/configscript, the autoconfig(8), program and descibes the major and minor device numbers and their encoding. The DIAGNOSTICS section lists messages which may appear on the console and/or in the system error log /usr/adm/messages due to errors in device oper- ation. This section contains both devices which may be configured into the system, ``4'' entries, and network related information, ``4N'', ``4P'', and ``4F'' entries; The networking support is introduced in intro(4N).
PDP DEVICE SUPPORT
This section describes the hardware supported on the DEC PDP-11. Software support for these devices comes in two forms. A hardware device may be supported with a character or block device driver, or it may be used within the networking subsystem and have a network interface driver. Block and character devices are accessed through files in the file system of a special type; c.f. mknod(8). Network interfaces are indirectly accessed through the interprocess communication facilities provided by the system; see socket(2). A hardware device is identified to the system at configuration time and the appropriate device or network interface driver is then compiled into the system. When the resultant system is booted, the autoconfiguration facilities in the system probe for the device on either the UNIBUS (or Q-bus) or MASSBUS and, if found, enable the software support for it. If a device does not respond at autoconfiguration time it is not accessible at any time afterwards. To enable a device which did not autoconfigure, the system will have to be rebooted. The autoconfiguration system is described in autoconfig(8). A list of the supported devices is given below.

LIST OF DEVICES
The devices listed below are supported in this incarnation of the system. Pseudo-devices are not listed. Listed also are devices which are in various stages of porting to 2.11BSD from 4.3BSD. Devices are indicated by their functional interface. If second vendor products provide functionally identical interfaces they should be usable with the supplied software. (Beware, however, that we promise the software works ONLY with the hardware indicated on the appropriate manual page.) Occasionally, new devices of a simi- lar type may be added simply by creating appropriate table entries in the driver. The following are known to work: acc ACC LH/DH IMP communications interface de DEC DEUNA 10Mb/s Ethernet controller dh DH-11 emulators, terminal multiplexor dhu DHU-11 terminal multiplexor dz DZ-11 terminal multiplexor ec 3Com 10Mb/s Ethernet controller hk RK6-11/RK06 and RK07 moving head disk ht TM03 MASSBUS tape drive interface (with TE-16, TU-45, TU-77) il Interlan 1010, 1010A, 2010A 10Mb/s Ethernet controller lp LP-11 parallel line printer interface qe DEC DEQNA Q-bus 10 Mb/s Ethernet interface ra DEC UDA-50, RQDX, KLESI disk controllers rk DEC RK05 disk controller rl DEC RL-11 disk controller rx DEC RX02 floppy interface si SI 9500 disk controller tm TM-11/TE-10 tape drive interface tmscp TMSCP-compatible tape controllers (e.g., TU81, TK50) ts TS-11 tape drive interface vv Proteon proNET 10Mb/s and 80Mb/s ring network interface xp General purpose SMD disk controller The following should work: dr DR-11W general purpose DMA UNIBUS interface The following worked in the past but will probably require work: css DEC IMP-11A communications interface dmc DEC DMC-11/DMR-11 point-to-point communications device en Xerox 3Mb/s Ethernet controller (obsolete) sri DR-11C IMP interface It should be possible to port these from 4.3BSD: ex Excelan 10Mb/s Ethernet controller ix Interlan NP-100 10Mb/s Ethernet controller np Interlan NP-100 10Mb/s Ethernet controller (intelligent mode) pcl DEC PCL-11 communications interface No idea whether any of the following could be ported: ad Data translation A/D interface ct C/A/T or APS phototypesetter ddn ACC ACP625 DDN Standard Mode X.25 IMP interface dmf DEC DMF-32 terminal multiplexor and parallel printer interface dmz DEC DMZ-32 terminal multiplexor dn DEC DN-11 autodialer interface hdh ACC IF-11/HDH IMP interface hp MASSBUS disk interface (with RP06, RM03, RM05, etc.) hy DR-11B or GI-13 interface to an NSC Hyperchannel kg KL-11/DL-11W line clock mt TM78 MASSBUS tape drive interface tu VAX-11/730 TU58 console cassette interface un DR-11W interface to Ungermann-Bass up Emulex SC-21V, SC-31 UNIBUS disk controller ut UNIBUS TU-45 tape drive interface uu TU58 dual cassette drive interface (DL11) va Benson-Varian printer/plotter interface vp Versatec printer/plotter interface 4th Berkeley Distribution January 27, 1996 INTRO(4)
