will have instant off capabilities as long as the BIOS has control of the
system. When the Standby or Suspend feature is enabled or when the
BIOS is not in control such as during memory count (the first screen that
appears when the system is turned on), the momentary on/off switch must
be held for more than four seconds to shut down the system. This feature
is required to implement the ACPI features on the motherboard.
Question: I see some of my PCI devices sharing IRQs, but the sys-
tem seems to be fine. Is this correct or not?
Answer: Some PCI Bus Mastering devices can share IRQs without perfor-
mance penalties. These devices are designed to work correctly while shar-
ing IRQs. See Table 3-1 below for details on shared IRQs.
Table 3-1. Shared IRQs
P3TSSA
PCI 1 shares an IRQ with PCI 5, the AGP Pro slot and onboard VGA
PCI 2 shares an IRQ with PCI 6, onboard audio and SM bus*
PCI 3 has a dedicated IRQ (does not share)
PCI 4 shares an IRQ with USB
P3TSSR
PCI 1 shares an IRQ with onboard LAN2, the 4xAGP slot and onboard VGA
PCI 2 shares an IRQ with the onboard SCSI and the SM bus*
PCI 3 has a dedicated IRQ (does not share)
PCI 4 shares an IRQ with the USB and onboard LAN1**
P3TSSE
PCI 1 shares an IRQ with onboard LAN2, the 4xAGP slot and onboard VGA
PCI 2 shares an IRQ with the SM bus*
PCI 3 has a dedicated IRQ (does not share)
PCI 4 shares an IRQ with the USB and onboard LAN1**
*System Management Bus
** The PCI 4 slot shares resources with onboard LAN1. LAN1 must be
disabled to use the PCI 4 slot.
