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.
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. Default setting is No.
Slot 1 (RIGHT) IRQ to Slot 4 (LEFT) 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, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.
PCI Latency Timer (32 PCI Clock)
The default setting of 32 PCI Clock enables maximum PCI performance for this
motherboard.
IRQ xx Used By ISA (No/ICU)
These fields indicate whether or not the displayed IRQ for each field is being used
by a legacy (non-PnP) ISA card. Two options are available: No/ICU (default) and
Yes. No/ICU indicates either that the displayed IRQ is not used or an ISA Configura-
tion Utility (ICU) is being used to determine if an ISA card is using that IRQ. If you
install a legacy ISA card that requires a unique IRQ, and you are not using an ICU,
you must set the field for that IRQ to Yes. For example: If you install a legacy ISA
card that requires IRQ 10, then set IRQ10 Used By ISA to Yes.
