36 driver enumerates ISA devices which support
37 .Dq "Plug and Play ISA Specification"
39 It assigns ISA bus resources (interrupt line, DMA channel, I/O ports,
40 and memory region) to each device and activates it.
42 If it cannot assign necessary resources to a PnP ISA device without
43 causing conflict with other devices in the system,
44 the device will not be activated and will be unavailable

63 driver first appeared in
65 It has been substantially updated in subsequent versions.
68 PnP support was originally written
73 based on initial work done by
76 It is not possible to disable individual PnP ISA devices.
79 driver will find all devices conforming the PnP ISA specification
80 and try to activate them all.
82 There is no way to explicitly assign particular resource to
84 The resource assignment is fully automatic and there is
85 no provision for manual override.
