set of I/O features onboard, including two 16550A UART compatible serial

ports, one EPP/ECP capable parallel port and support fur state-of-the-art

Universal Serial Bus (USB) through the optional USB riser card providing

ease-of-use and high-speed Plug & Play connections to future USB complaint

peripheral devices. System I/O connectivity is further enhanced by an IrDA

complaint serial port, an optional PS/2 Keyboard & PS/2 Mouse port and

optional onboard SIR support.

Ample expansion is provided for with four 16-bit ISA slots and four 32-bit PCI

slots. The VT-501 also comes with a built-in Enhanced PCI Bus Master PCI

IDE controller that provides high speed connections to a full range of IDE

devices including HDD, CD-ROM and Tape-Drives, and delivers ultra fast

data transfer up to 20MB/sec through its support for PIO Mode3, Mode4 and

DMA Mode 2.

VT-501 Mainboard Manual

This User Manual

This manual is designed to guide you and facilitate your use of the VT-501

mainboard. It contains a description of the design and features of the

mainboard, and also includes useful information for changing the configuration

of the board and the system it is installed in. The manual is divided into three

chapters:

■Chapter 1 - Overview

gives an overview of the mainboard and describes its major components

and features.

■Chapter 2 - Installation Procedures

gives instructions on how to set up the mainboard, including jumper

settings and CPU installation guides.

■Chapter 3 - Award BIOS Setup

briefly explains the mainboard’s BIOS system setup in general and tells

you

how to run it and change the system configuration settings.

NOTE : The material in this manual is for information only and is subject to

change without notice. We reserve the right to make changes in the product

design without reservation and without notification to its users. We shall not be

liable for technical or editorial omissions made herein; nor for incidental or

consequential damages resulting from the furnishing, performance, or use of

this material.

Overview

Something Interesting

This section provides useful information that you will need to know should you

decide to modify or upgrade the configuration of the mainboard and the system

it is installed in. If you do not have the confidence to upgrade the mainboard

yourself, we advise that you consult a qualified service technician for

assistance.

The BIOS Setup Utility

The BIOS (Basic Input Output System) is the basic firmware that instructs the

computer how to operate. For the BIOS to work properly, there must be a

record of the computer’s hardware and configuration settings for it to refer to.

This record is created using the Setup Utility, a program that is stored

permanently in the BIOS ROM chip on the mainboard.

The system configuration record created by the Setup Utility is also stored on

the mainboard, but not permanently. This section of the memory it is stored is

in the NVRAM.

When you buy your computer, the system configuration record will already be

set and may in some cases differ from the basic defaults. The first time you use

your computer or when you need to re-configure your system, you should run

the Setup Utility and write down the settings.

VT-501 Mainboard Manual

IRQ Functionality

As you read through this manual, you will see the term IRQ on a number of

occasions. It is important for you to know what this term means, particularly if

you intend to upgrade your system.

IRQ stands for Interrupt Request, the process in which an input or output

device tells the processor to temporarily interrupt its current task and

immediately process something from the source of the interrupt. When it has

completed this, the processor returns to the task it was already processing.

Devices that need an

IRQ line to operate sometimes need to have exclusive use of that line.

A large number of add-on cards, such as sound cards and LAN cards, require

the use of an IRQ line to function. Some no. of IRQs may already be in use by

components in the system such as the keyboard and mouse. Add-on cards that

need to use an IRQ draw from the unused group of IRQs. When installing a

card that uses an IRQ, it will have a default IRQ setting which you might have

to change if that IRQ is already in use and cannot be shared.

Both ISA and PCI add-on cards may need to use IRQs. System IRQs are

available to add-on cards installed on the ISA bus first; the remaining ones can

be used by cards installed on the PCI bus. There are two categories of ISA add-

on cards: so-called Legacy ISA cards, which need to be configured manually

and then installed in any available ISA slot; and Plug and Play (PnP) ISA

cards, which are configured automatically by the system. As a result, when you

install Legacy ISA cards, you have to carefully configure the system to ensure

that the installed cards do not conflict with each other by having the same IRQ.

With PnP cards, on the other hand, IRQs are assigned automatically from the

ones available in the system. In the case of PCI add-on cards, the BIOS

automatically assigns an IRQ card to the PCI slot the card is installed in.

Overview

DMA Channels of ISA Cards

Some Legacy and PnP ISA add-on cards may also need to use a Direct

Memory Access (DMA) channel. DMA assignments for this mainboard are

handled in the same way as the IRQ assignment process outlined above. For

more information, please refer to Chapter 3 of this manual.

Enhanced IDE

This mainboard features an integrated Enhanced IDE controller that provides

convenient, high-speed connections with up to four IDE devices, such as Hard

Disk, CD-ROM and Tape Backup Drives. Enhanced IDE is an upgrade of the

original IDE specification and provides increased capabilities and performance

in a number of areas, including support for Hard Disk Drives of over 1.2GB

and faster data transfer rates utilizing the PIO Mode 4 timing scheme.

With the integrated IDE controller you can connect up to four IDE peripheral

devices to your system. All devices are categorized in the same way that IDE

Hard Disks were configured in the past, with one device set as the Master

device and the other as the Slave device. We recommend that Hard Disk

Drives use the Primary IDE connector and that CD-ROM drives utilize the

Secondary IDE connector for improved system performance.

VT-501 Mainboard Manual

Serial Infrared (SIR) Connections

This mainboard features support for highly-sophisticated SIR technology,

which allows bi-directional and cordless data transactions with other IrDA

compliant computers and peripheral devices using infrared as a medium. This

transmission is carried out in either Full Duplex Mode or Half Duplex Mode.

The former allows simultaneous data transmission and reception, while the

latter disables the reception when transmission occurs.

The I/O chipset on this mainboard features a SIR interface that is fully

compliant with the IrDA standard. An IrDA device can be installed via a 9-pin

D-SUB connector in the rear panel of the computer which is linked by a cable

to the onboard IrDA pinhead, as shown in the illustration below.

The serial port COM2 on this mainboard is designed to be an SIR compliant

port. If you wish to install the SIR connection feature, you need to adjust the

BIOS option for high-speed performance.

Overview

Highly Convenient Integrated I/O Connectors

This mainboard features has an integrated rear I/O panel that incorporates a

full set of I/O ports to allow simple and convenient connections to a complete

selection of external peripheral devices.

In addition to two 16550A UART compatible serial ports and one EPP/ECP

capable parallel port, the panel features two USB connectors that provide high

speed connection to the next generation of USB devices. PS/2 keyboard and

PS/2 mouse connectors provide additional I/O connectivity.
