DESCRIPTION

The pnp driver enumerates ISA devices which support ""Plug and Play ISA Specification"" in the system. It assigns ISA bus resources (interrupt line, DMA channel, I/O ports, and memory region) to each device and activates it.

If it cannot assign necessary resources to a PnP ISA device without causing conflict with other devices in the system, the device will not be activated and will be unavailable to programs.

CAVEATS

It is not possible to disable individual PnP ISA devices. The pnp driver will find all devices conforming the PnP ISA specification and try to activate them all.

There is no way to explicitly assign particular resource to the PnP ISA device. The resource assignment is fully automatic and there is no provision for manual override.
