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 En-
abled, 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)
• IRQ12 (PS/2)
• IRQ13 (Coprocessor)
• IRQ14 (Hard Disk)
• IRQ15 (Reserved)
