such a mode. In effect, the system remains alert for anything which occurs to a device
which is configured as
On
, even when the system is in a power down mode.
When an I/O device wants to gain the attention of the operating system, it signals this by
causing an IRQ to occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service. As above, the choices are
On
and
Off. Off
is the
default. When set
On
, activity will neither prevent the system from going into a power
management mode nor awaken it.
You can set IRQ3 - 15 individually. Activity detected from any enabled IRQ channel will
wake up the system.

nterconnect Bus was developed by Intel and other industry
leader partners primarily to address two important issues faced by PC hardware designers
today: a) How to allow peripheral devices to take the fullest advantage of the power of
Pentium and Pentium Pro chip technology, and b) Provide a simpler installation process for
peripheral devices, such as Network cards, EIDE or SCSI controllers.
PCI accomplishes these goals with its 32-bit Data path Local Bus design, and support for
Plug & Play. Unlike older expansion bus architectures, PCI provides peripherals with a
direct connection to the CPU and memory. The PCI bus runs at 33Mhz and has a maximum
transfer capability of 132MBps. With Plug & Play, the system BIOS automatically
determines hardware resources for new peripherals, simplifying installation of multiple
interface cards.
This Setup Menu provides configuration options for the PCI Bus and its assigned resources.
