PNP/PCI Configuration

This section describes configuring the PCI bus system.  PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the
speed the CPU itself uses when communicating with its own special components.

Resources Controlled By
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 request (IRQ) and DMA
assignment fields disappear, as the BIOS automatically assigns them. Choice:  Auto and
Manual.

Reset Configuration Data
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. Choice:  Enabled and Disabled.

IRQ n Assigned to
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
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
This sets the method by which the PCI bus recognizes that an IRQ service is being
requested by a device.  Under all circumstances, you should retain the default configura-
tion unless advised otherwise by your system's manufacturer.
The choice:  Level,  Edge.
