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 _c_o_n_f_i_g(8) program.
The DIAGNOSTICS section lists messages which may appear on
the console and/or in the system error log /_u_s_r/_a_d_m/_m_e_s_s_a_g_e_s
due to errors in device operation; see _s_y_s_l_o_g_d(8) for more
information.
This section contains both devices which may be configured
into the system, ``4'' entries, and network related informa-
tion, ``4N'', ``4P'', and ``4F'' entries; The networking
support is introduced in _i_n_t_r_o(4N).
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 _d_e_v_i_c_e _d_r_i_v_e_r, or it may be used within the net-
working subsystem and have a _n_e_t_w_o_r_k _i_n_t_e_r_f_a_c_e _d_r_i_v_e_r.
Block and character devices are accessed through files in
the file system of a special type; c.f. _m_k_n_o_d(8). Network
interfaces are indirectly accessed through the interprocess
communication facilities provided by the system; see
_s_o_c_k_e_t(2).
A hardware device is identified to the system at configura-
tion 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 autoconfigura-
tion time it is not accessible at any time afterwards. To
enable a UNIBUS device which did not autoconfigure, the sys-
tem 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 _a_u_t_o_c_o_n_f(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, how-
ever, that we promise the software works ONLY with the
hardware indicated on the appropriate manual page.) Occa-
sionally, new devices of a similar type may be added simply
by creating appropriate table entries in the driver.
