Specifications

PCI Auto-configuration

The PCI auto-configuration works in conjunction with the Setup program to support

using PCI add-in boards in the system. When you turn on the system power after

installing a PCI board, the BIOS automatically configures interrupts, DMA channels, I/O

space, and so on. Since PCI add-in boards use the same interrupt resources as ISA

add-in boards, you must specify the interrupts used by non PnP ISA boards in the

Setup program. Chapter 3 tells how to use the Setup program. The PCI auto-

configuration program complies with version 2.1 of the PCI BIOS specification.

IDE Auto-configuration

When an IDE drive is installed in the system, the IDE auto-configuration function

automatically detects and configures the drive for operation in the system. This function

eliminates the need to enter the Setup program after you install an IDE drive.

ISA Plug and Play Capability

This provides auto-configuration of Plug and Play ISA cards and resource management

for legacy (non Plug and Play) ISA cards.

Universal Serial Bus (USB) Support

The USB technology enables users to quickly and easily attach and reconfigure a wide

range of peripheral devices, from keyboards to printers to telephony devices. With

comprehensive support for both USB host controllers and USB devices, AWARD BIOS

offers the ability to fully utilize USB technology. The motherboard features two USB

ports as a factory installed option. The ports permit the direct connection of two USB

peripherals without an external hub. If more devices are required, an external hub can

be connected to either of the built-in ports This motherboard fully supports the standard

Universal Host Controller Interface (UHCI) and uses standard software drivers that are

UHCI compatible. Features of the USB include:

• Self-identifying, hot pluggable peripherals.

• Automatic Mapping of function to driver and configuration.

• Support for Isochronous and Asynchronous transfer types over the same set of

wires.

• Support for up to 127 physical devices.

• Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other

applications.

Error handling and fault recovery mechanisms built into protocol.
