PNP and PCI Setup
The “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.
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.
Details of PNP and PCI Setup
PNP OS Installed (No)
This field allows you to use a Plug-and-Play (PnP) operating system to configure
the PCI bus slots instead of using the BIOS. Thus interrupts may be reassigned by
the OS when Yes is selected. When a non-PnP OS is installed or to prevent reassign-
ing of interrupt settings, select the default setting of No.
Slot 1 IRQ / Slot 2 IRQ / Slot 3 IRQ (Auto)
These fields set how IRQ use is determined 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 NA, 3, 4, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.
Slot 4/5/Audio IRQ (5)
This field sets the IRQ for PCI slots 4 and 5, which is shared with the onboard audio
The default setting for this field is 5.
PCI Latency Timer (32 PCI Clock)
The default setting of 32 PCI Clock enables maximum PCI performance for this
motherboard.
