INTRO(4)             NetBSD/hp700 Kernel Interfaces Manual            INTRO(4)

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 specifi-
     cation for use in constructing a system description for the config(1)
     program.  The DIAGNOSTICS section lists messages which may appear on the
     console and/or in the system error log /var/log/messages 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).

DEVICE SUPPORT
     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 device driver, or it may be
     used within the networking subsystem and have a network interface driver.
     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 autoconfigura-
     tion 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).

LIST OF DEVICES
     The devices listed below are supported in this incarnation of the system.
     Devices are indicated by their functional interface.  Not all supported
     devices are listed.

     asp(4)       The ASP I/O controller; found in most of the older machines
                  which don't have LASI or WAX.  Includes GSC-bus controller,
                  to which most of the devices are attached.  Most of I/O is
                  still on external chips though.

     com(4)       The RS-232 ports.

     cpu(4)       The Central Processor itself, makes sure the machine does
                  something useful.

     tlp(4)       DEC/Intel 21140, 21143, 21145 and clone 10/100 Ethernet con-
                  roller.

     dino(4)      The pci(4) bridge on most of the newer systems.

     harmony(4)   CS4215/AD1849 audio.

     hil(4)       Human Interface Loop, sporting several input devices, e.g.
                  keyboards, mice, tablets and such.

     iee(4)       i82596 CA/DX LAN controller.  Found in every 700, either
                  included in the MBA or on an external chip on mainboard.

     lasi(4)      LSI?, found in almost all HP 9000/700 workstations.  Inte-
                  grates most of the bus and I/O functions into one chip.

     lpt(4)       The Centronics printer port.

     mem(4)       Memory files and memory controller.

     mongoose(4)  The eisa(4) bus controller on most of the older 700
                  machines.

     oosiop(4)    Symbios/NCR 53C700 SCSI I/O processor.

     osiop(4)     Symbios/NCR 53C710 SCSI I/O processor.

     pdc(4)       The PROM interface, allows to call the routines in the
                  machine's PROM for things like initial console output and
                  such.

     siop(4)      LSI/Symbios Logic/NCR 53C8xx SCSI I/O processor.

     sti(4)       The system graphics driver.

     wax(4)       The other reincarnation of lasi(4) used for cheap ASIC
                  implementations for add-on devices.
