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  man‐
       ual,  the  SYNOPSIS  section of each configurable device gives a sample
       specification for use in constructing a system description for the con���
       fig(8)  program.   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; see syslogd(8) for more information.

       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).

VAX DEVICE SUPPORT
       This section describes the hardware supported on the DEC VAX-11.  Soft‐
       ware 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 autoconfigu‐
       ration  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 UNIBUS device does not respond at autoconfiguration time
       it is not accessible at any time afterwards.  To enable a UNIBUS device
       which did not autoconfigure, the system will have to be rebooted.  If a
       MASSBUS device comes ‘‘on-line’’ after the  autoconfiguration  sequence
       it will be dynamically autoconfigured into the running system.

       The  autoconfiguration  system  is described in autoconf(4).  A list of
       the supported devices is given below.

LIST OF DEVICES
       The devices listed below are supported in this incarnation of the  sys‐
       tem.   Pseudo-devices  are  not listed.  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 similar type may be added simply by  creating  appropriate
       table entries in the driver.
