NAME
intro —
introduction to vax 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
config(1) program. The
DIAGNOSTICS section lists messages which may appear on the console and/or in
the system error log
/var/log/messages due to errors in
device operation; see
syslogd(8) for more
information.
VAX DEVICE SUPPORT
This section describes the hardware supported on the DEC VAX-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; see
physio(4) and
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 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
vax/vax/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 system.
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.
