intro —
introduction to atari special files and hardware support
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 specification 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 system and network related information. The networking support is
    introduced in
    netintro(4).
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 support.
- Hades
- A standard Hades with either an 040 or 060 processor and at least 8 Mb of
      RAM.
 
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 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). A list of
    the supported devices is given below.
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.
