     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).

     This section describes the hardware supported on the Mac. Software sup-
     port for these devices comes in two forms.  A hardware device may be sup-
     ported 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 spe-
     cial 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 will have to be rebooted.

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