INTRO(4) Kernel Interfaces Manual INTRO(4)
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 specification 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 operation.
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 appropri-
ate manual page.) Occasionally, new devices of a similar 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)

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:
