     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 _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
     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
     system and network related information.  The networking support is
     introduced in netintro(4).

DDEEVVIICCEE SSUUPPPPOORRTT
     This section describes the hardware supported on the HP PA-RISC 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.
     Character and block 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
     autoconfiguration time it is not accessible at any time afterwards.  To
     enable a device which did not autoconfigure, the system must be rebooted.

     The autoconfiguration system is described in autoconf(4).
