C 7 intro - introduction to 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 (8) program. The DIAGNOSTICS section lists messages which may appear on the console and in the system error log /usr/adm/messages due to errors in device operation.

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 on the VERSAbus and, if found, enable the software support for it. If a VERSAbus device does not respond at autoconfiguration time it is not accessible at any time afterwards. To enable a VERSAbus device which did not autoconfigure, the system will have to be rebooted.

The autoconfiguration system is described in autoconf (4).

autoconf(4), netintro(4), config(8) The devices listed below are supported in this incarnation of the system. Devices are indicated by their functional interface. If second vendor products provide functionally identical interfaces they should be usable with the supplied software. (Beware however that we promise the software works ONLY with the hardware indicated on the appropriate manual page.)
