.Sh NAME
|
|
.Nm pnp
|
|
.Nd support for
|
|
.Dq "Plug and Play"
|
|
(PnP) ISA devices
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver enumerates ISA devices which support
|
|
.Dq "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.
|
|
.Pp
|
|
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.
|
|
.Sh CAVEATS
|
|
It is not possible to disable individual PnP ISA devices.
|
|
The
|
|
.Nm
|
|
driver will find all devices conforming the PnP ISA specification
|
|
and try to activate them all.
|
|
.Pp
|
|
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.
