If the operating system (OS) is Plug and Play (for example
Windows 95), select "Yes" if you want the OS to allocate
resources according to Plug and Play standards, or "No" if you
want the same resource allocations at every system boot-up.
Select "No" when the OS is not Plug and Play (for example, DOS).
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.
Normally, you leave this field Disabled. Select Enabled 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.
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,
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.
When Legacy ISA is selected for an IRQ line, this resource will not
be available for PCI/ISA PnP.
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.
When Legacy ISA is selected for a DMA channel, this resource
will not be available for PCI/ISA PnP.
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.
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.
Select a base address for the memory area used by any
peripheral that requires high memory.
Select a length for the memory area specified in the previous field.
This field does not appear if no base address is specified.
