35 .Nd support for embedded devices on the motherboard
41 driver enumerates embedded ISA devices on the motherboard whose BIOS
43 .Dq "Plug and Play BIOS 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 device without
48 causing conflict with other devices in the system,
49 the device will not be activated and will be unavailable
52 There is no explicit way to disable individual embedded devices.
55 driver will find all devices reported by the
56 .Dq "Plug and Play (PnP)"
57 BIOS and try to activate them all.
59 There is no way to explicitly assign particular resource to a device.
60 The resource assignment is fully automatic and there is
61 no provision for manual override.
