PM Events
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.
When an I/O device wants to gain the attention of the operating
system, it signals this by causing an IRQ (Interrupt ReQuest) to
occur. When the operating system is ready to respond to the
request, it interrupts itself and performs the service. The following
is a list of IRQs, which can be disabled:
• COM Ports Activity
• LPT Ports Activity
• HDD Ports Activity
• VGA Activity
• 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)
• IRQ12 (PS/2 Mouse)
• IRQ13 (Coprocessor)
• IRQ14 (Hard Disk)
• IRQ15 (Reserved)
