intro -- introduction to hp300 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 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).
HP DEVICE SUPPORT
This section describes the hardware supported on the HP 9000/300 series.
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 will have to be rebooted.
The autoconfiguration system is described in hp300/autoconf(4).
LIST OF DEVICES
The devices listed below are supported in this incarnation of the system.
Pseudo-devices are not listed. Devices are indicated by their functional
interface. Occasionally, new devices of a similar type may be added sim-
ply by creating appropriate table entries in the driver; for example, new
com serial interfaces (98644, 98626, and built-in apci and
