Settings
Description
PNP OS Installed No No Yes ; No If the operating system (OS) is Plug-and-Play, select ‘Yes’ if you
want the OS to allocate resources according to PnP standards, or
‘No’ if you want the same resource allocation at every system boot-
up. Select ‘No’ when the OS is not PnP (for example DOS).
Resources Controlled
By Auto Man. Auto ; Manual The Award Plug and Play BIOS can automatically configure all the
boot and Plug and Play-compatible devices. If you select Auto, all
the interrupt requests (IRQs) and DMA assignment fields disappear,
as the BIOS automatically assigns them.
Reset Configuration
Data Dis. Dis. En. ; Dis. Normally, you leave this field Disabled. Select En. to reset Extended
System Configuration Data (ESCD) when you exit Setup if you have
installed a new add-on and the system reconfiguration has caused
such a serious conflict that the operating system cannot boot.
IRQ n Assigned To
(n=0, 1, 3, 5, 6, 7)
PCI/ISA PnP ;
Legacy ISA
When resources are controlled manually, assign each system
interrupt as one of the following types, depending on the type of
device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific interrupt (such as IRQ4 for serial
port 1).
PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
DMA n Assigned To
(n=3, 4, 5, 7, 9, 11, 12,
13, 14, 15)
PCI/ISA PnP ;
Legacy ISA
When resources are controlled manually, assign each system DMA
channel as one of the following types, depending on the type of
device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific DMA channel.
PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
PCI IRQ Activated By Level Level Level ; Edge Leave the IRQ trigger set at Level unless the PCI device assigned to
the interrupt specifies Edge-triggered interrupts.

This field lets you select PCI IDE IRQ mapping or PC AT (ISA)
interrupts. If your system does not have one or two PCI IDE
connectors on the system board, select values according to the type
of IDE interface(s) installed in your system (PCI or ISA). Standard
ISA interrupts for IDE channels are IRQ14 for primary and IRQ15 for
secondary.
Primary IDE INT

Secondary IDE INT
#
A A A ; B ; C ; D Each PCI peripheral connection is capable of activating up to four
interrupts: INT
#
A, INT
#
B, INT
#
C and INT
#
D. By default, a PCI
connection is assigned INT
#
A. Assigning INT
#
B has no meaning
unless the peripheral device requires two interrupt services rather
than just one. Because the PCI IDE interface in the chipset has two
channels, it requires two interrupt services. The primary and
secondary IDE INT
#
fields default to values appropriate for two PCI
IDE channels, with the primary PCI IDE channel having a lower
interrupt than the secondary.
Used Mem Base
Address N/A N/A NA ; C800 ; CC00

Select a base address for the memory area used by any peripheral
that requires high memory.
Used Mem Length - - 4K, 16K, 32K,

Select a length for the memory area specified in the previous field.
This field does not appear if no base address is specified.
