Installing Plug and Play devices

Plug and Play files and utilities


/dev/Pnp
Kernel device driver used to recognize and query ISA Plug and Play hardware, and to allocate resources to that hardware. Any settings specified in /etc/conf/pack.d/PnP/space.c are used as directives.

/etc/isapnpslot
Utility which uses /dev/PnP to extract current and possible resource information. When new resources are specified by the ISA PnP Configuration Manager, isapnpslot verifies that the resource allocation is valid.

/etc/pnp
The ISA PnP Configuration Manager. This utility uses information provided by isapnpslot to display card and device resource selections. When the user sets resources, disables devices, or otherwise modifies the Plug and Play hardware, /etc/pnp rewrites /etc/conf/pack.d/PnP/space.c to reflect the changes.

/dev/string/cfg
A special file (not directly viewable) that contains existing driver settings. The data contained in this file is normally displayed during system boot or by using the hwconfig(C) command.

/etc/hw
A utility used by isapnpslot to obtain system hardware information about EISA, ISA, MCA and PCI buses.

/usr/lib/hw
A database used by isapnpslot to obtain system hardware information about EISA, ISA, MCA and PCI buses.
