Plug & Play/PCI
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. 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/Audio IRQ / Slot 4/5 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. If onboard audio is
selected, PCI Slot 5 can only be used with a PCI slave device. 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.
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 and Yes. The
first option, the default value, indicates either that the displayed IRQ is not used or
an ISA Configuration 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 Ye s. For example: If you
install a legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Yes.
