Power Down & Resume Events (IRQ 3 - 15)
Power Down and Resume events are I/O events whose occurrence can
prevent the system from entering a power saving mode or can awaken
the system from 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.
The following is a list of IRQ's, Interrupt ReQuests, which can be ex-
empted much as the COM ports and LPT ports above can. 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.
When set on, activity will neither prevent the system from going into a
power management mode nor awaken it.
The default value is On.
On
Off
The activity of this event causes the power management tim-
ers to be reset, i.e., the Power Management Unit (PMU)
monitors the specified activities as power management
events.
The activity of this event will not affect the power manage-
ment timers.
PNP/PCI Configuration Setup
This section describes configuring the PCI bus system. PCI, or Personal
Computer Interconnect, is a system which allows I/O devices to operate
at speeds nearing the speed the CPU itself uses when communicating
with its own special components. This section covers some very techni-
cal items and it is strongly recommended that only experienced users
should make any changes to the default settings.
