PM 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 Enabled, even when the
system is in a power down mode.
The following is a list of IRQ, Interrupt ReQuests, which can be
exempted 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.
• IRQ3 (COM 2)
• IRQ4 (COM 1)
• IRQ5 (LPT 2)
• IRQ6 (Floppy Disk)
• IRQ7 (LPT 1)
• IRQ8 (RTC Alarm)
• IRQ9 (IRQ2 Redir)
• IRQ10 (Reserved)
• IRQ11 (Reserved)
