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.
