     iinnttrroo - introduction to special files and hardware support

DDEESSCCRRIIPPTTIIOONN
     The manual pages in section 4 describe the special files, related driver
     functions, and networking support available in the system.  In this part
     of the manual, the _S_Y_N_O_P_S_I_S section of each configurable device gives a
     sample specification for use in constructing a system description for the
     config(8) program.  The _D_I_A_G_N_O_S_T_I_C_S section lists messages which may ap-
     pear 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 SPARC 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 ac-
     cessed 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.

     The devices listed below are supported in this incarnation of the system.
     Pseudo-devices are not listed.  Devices are sorted by their type and
     driver name; not all supported devices are listed.
