NAME

     intro -- introduction to atari 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).


LIST OF PLATFORMS SUPPORTED

     Platforms supported by the atari port:
           TT030   A standard TT030 model with at least 4Mb of RAM.
           Falcon  A standard Falcon with at least 4Mb of RAM. An FPU is not
                   required as the default kernels include FP-emulation sup-
                   port.
           Hades   A standard Hades with either an 040 or 060 processor and at
                   least 8 Mb of RAM.


DEVICE SUPPORT

     This section describes the hardware supported on the atari (atari-clone)
     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.  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
     device 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.


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, not all devices exist on all models.

     Standard builtin devices:
           clock    System clock
           fd       Floppy device as found on the Falcon/TT030
           grf      The standard internal video as found on the Falcon and
                    TT030.
           grfet    The et4000-PCI video as found on the HADES
           hdfd     Floppy device as found on the Hades (NEC 765 compatible)
           isa      ISA I/O bus (Hades only)
           kbd      Standard keyboard
           lpt      Parallel port device interface
           mem      Main memory interface
           ncrscsi  Onboard 5380 SCSI-bus
           nvr      Non-volatile RAM interface
           pci      PCI I/O bus (Hades only).
           ser0     Serial1 (when connector available).
           vme      VME I/O bus
           wd       IDE interface (not on TT030)
           zs0      Serial2 and modem2 ports.
