41 driver enumerates ISA devices which support
42 .Dq "Plug and Play ISA Specification"
44 It assigns ISA bus resources (interrupt line, DMA channel, I/O ports,
45 and memory region) to each device and activates it.
47 If it cannot assign necessary resources to a PnP ISA device without
48 causing conflict with other devices in the system,
49 the device will not be activated and will be unavailable
52 It is not possible to disable individual PnP ISA devices.
55 driver will find all devices conforming the PnP ISA specification
56 and try to activate them all.
58 There is no way to explicitly assign particular resource to
60 The resource assignment is fully automatic and there is
61 no provision for manual override.
