     iinnttrroo - introduction to special files and hardware support

DDEESSCCRRIIPPTTIIOONN
     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 config(8)
     program.  The DIAGNOSTICS section lists messages which may appear on the
     console and/or in the system error log _/_v_a_r_/_l_o_g_/_m_e_s_s_a_g_e_s due to errors in
     device operation; see syslogd(8) for more information.

     This section contains both devices which may be configured into the sys-
     tem and network related information.  The networking support is intro-
     duced in netintro(4).

DDEEVVIICCEE SSUUPPPPOORRTT
     This section describes the hardware supported on the i386 (PC-clone)
     platform.  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 networking 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; see 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 and, if found, enable the
     software support for it.  If a device does not respond at autoconfigura-
     tion time it is not accessible at any time afterwards.  To enable a de-
     vice which did not autoconfigure, the system must be rebooted.

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