PM Events

This section sets the wake-up call of the system. If activity is detected from any

enabled IRQ channels in the left-hand group, the system wakes up from suspended

mode. You can enable power management for IRQs 3 ~ 15 individually in the list at

the right of the screen. The power management feature will work on the enabled

IRQ channels.

Take note that a Microsoft serial mouse or compatible will use either COM1 (IRQ4)

or COM2 (IRQ3), and a PS/2 mouse will use IRQ12. If you know which IRQ your

mouse is using, you can enable the Wake-up Event for that IRQ here and the system

will wake up when you move the mouse or click its button.

IRQ3 to IRQ15

You can set IRQs 3 - 15 individually. Activity detected from any enabled IRQ

channel will wake up the system.

PNP and PCI Setup

This “PNP and PCI Setup” option configures the PCI bus slots. All PCI bus slots on

the system use INTA#, thus all installed PCI cards must be set to this value.

The first four fields on the screen set how IRQ is assigned for each PCI slot. The

default setting for each field is “Auto”, which uses auto-routing to determine IRQ

use. The other options are manual settings of “14” or “15” for each slot.

PCI Latency Timer

The default setting of “32 PCI Clock” enables maximum PCI performance for this

motherboard.
