AGP (Accelerated Graphics Port)

The system board is equipped with 1 AGP slot. AGP is an interface

designed to support high performance 3D graphics cards. It utilizes a

dedicated pipeline to access system memory for texturing, z-buffering

and alpha blending; delivering up to 533MB/sec. bandwidth for 3D

graphics applications. AGP in this Pentium II processor based system

board will deliver faster and better graphics with your PC .

SDRAM (Synchronous Dynamic Random Access Memory)

The system board supports unbuffered SDRAM memory. SDRAM is

a DRAM technology that uses the clock on the chip to synchronize

with the CPU clock so that the timing of the memory chips and the

timing of the CPU are synchronized. This saves time during

transmission of data, subsequently increasing system performance.

Ultra DMA/33 Bus Master IDE

Synchronous Ultra DMA mode provides data transfer rate up to a

maximum of 33MB/sec, which is twice the data transfer rate of

Enhanced IDE or ATA-2. This enables the CPU to operate more

efficiently when handling simultaneous events.

Connecting the Hard Disk Cable

1. If you are connecting two hard drives, install the 40-pin connector

of the IDE cable into the primary shrouded IDE header

(connector J6). If you are adding a third or fourth IDE device,

install the 40-pin connector of the other IDE cable into the

secondary shrouded IDE header (connector J5).

2. Install the other 40-pin header connector(s) into the device with

the colored edge of the ribbon cable aligned with pin 1 of the

drive edge connector(s).

Note:

Refer to your disk drive users manual for information about

selecting proper drive switch settings.

Adding a Second IDE Hard Drive

When using two IDE drives, one must be set as the master and the

other as the slave. Follow the instructions provided by the drive

manufacturer for setting the jumpers and/or switches on the drives.

We recommend that you use Enhanced IDE or ATA-2, ATA-3 and

Ultra DMA hard drives be from the same manufacturer. In a few

cases, drives from two different manufacturers will not function

properly when used together. The problem lies in the hard drives,

not the system board.

Important:

If you encountered problems while using an ATAPI CD-ROM

drive that is set in Master mode, please set the CD-ROM drive

to Slave mode. Some ATAPI CD-ROMs may not be recognized

and cannot be used if incorrectly set in Master mode.

Preparing an IDE Drive for Use

IDE disk drives are already low-level formatted, with any bad-track

errors entered, when shipped by the drive manufacturer. Do not

attempt to do a low-level format or you may cause serious damage

to the drive.

Memory

The base memory size, extended memory size and the other memory

size cannot be altered; your computer automatically detects and displays

them.

Base Memory The POST will determine the amount of base (or

conventional) memory installed in the system. The

value of the base memory is typically 512K for

systems with 512K memory installed on the

motherboard or 640K for systems with 640K or

more memory installed on the motherboard.

Extended Memory The BIOS determines how much extended

memory is present during the POST. This is the

amount of memory located above 1MB in the

CPUs memory address map.

Other Memory This refers to the memory located in the 640K to

1024K address space. This is the memor y that can

be used for different applications. DOS uses this

area to load device drivers in an effort to keep as

much base memory free for application programs.

The BIOS is the most frequent user of this RAM

area since this is where it shadows the ROM.

Virus Warning

This category protects the boot sector and partition table of your hard

disk drive. When this item is enabled, the Award BIOS will monitor the

boot sector and partition table of the hard disk drive. If an attempt

is made to write to the boot sector or partition table of the hard disk

drive, the BIOS will halt the system and an error message will appear.

After seeing the error message, if necessary, you will be able to run

an anti-virus program to locate and remove the problem before any

damage is done.

Many disk diagnostic programs which attempt to access the boot

sector table will cause the warning message to appear. If you are

running such a program, we recommend that you first disable this

category. Also, disable this category if you are installing or running

certain operating systems like Windows® 95 or the operating system

may not install nor work.

system chipset to provide support for gate A20.

Typematic Rate Setting

When disabled, continually holding down a key on your keyboard will

cause the BIOS to report that the key is down. When the typematic

rate is enabled, the BIOS will not only report that the key is down,

but will first wait for a moment, and, if the key is still down, it will begin

3.1.3 Chipset Features Setup

This section gives you functions to configure the system based on the

specific features of the chipset. The chipset manages bus speeds and

access to system memory resources. It also coordinates

communications between the conventional ISA bus and the PCI bus.

These items should not be altered unless necessary. Depending on your

add-in cards, you may not or should not enable some of those features.

The default settings have been chosen because they provide the best

operating conditions for your system. The only time you might consider

making any changes would be if you discovered some incompatibility

or that data was being lost while using your system.

Note:

The system board supports the optional System Health Monitor

function. If this function is supported, (a) the System Health

Monitor category will appear in the Chipset Features Setup; and

(b) the system board package will include the System Health

Monitor utility (refer to Chapter 4).

Once the utility is installed, the system will ignore the settings in

the System Health Monitor field of the Chipset Features Setup.

If you are using Windows 95 or Windows NT 4.0, you may

select between using the utility and the Chipset Features Setup.

For other operating systems, you may only use the Chipset

CPU Temperature Limit (optional)

This field allows you to manually set a limit to the processors

temperature. If the temperature of the processor is over the

temperature set in this field (70oC/158oF recommended), an alarm

will sound warning you of system overheat. The sound of the alarm

is continuous low to high beeps. Some of the most common causes

leading to high temperature are:

- The fan is not functioning normally or has stopped. Turn off your

system and replace the fan.

- The space clearance of the processor, fan and heat sink is

inadequate to maintain proper airflow and heat dissipation.

- The chassis or cabinet has poor ventilation.

CPU Fan Speed Limit and Chassis Fan Speed Limit (optional)

These fields allow you to manually set a limit to the speed of the CPU

and chassis fans. If the CPU/chassis fan speed is under the speed set

in these fields, an alarm will sound informing you to attend to any issue

that may damage your system. The sound of the alarm resembles that

of the siren of an ambulance. The failure detection circuit requires a

fan to operate at greater than 3600 RPM.

+1.5V, +3.3V, +5V and +12V Voltages (optional)

Set these fields to Monitor if you want the system board to detect

the output voltage of the power supply. If the output voltage is over

or under +1.5V/+3.3V/+5V/+12V (±10%), an alarm will sound

warning you of voltage issue. The sound of the alarm is continuous

low to high beeps but shorter than the temperature alarm. Some

of the most common causes leading to unstable output voltage of

4.1 Desktop Management Interface (DMI)

The system board comes with a DMI built into the BIOS. DMI,

along with the appropriately networked software, is designed to

make inventory, maintenance and troubleshooting of computer

systems easier. With DMI, a network administrator or MIS engineer

can remotely access some information about a particular computer

system without physically going to it. Quite often a service call may

be unnecessary as the problem can be solved remotely.

The DMI utility in the BIOS automatically records various information

about your system configuration. Information about the type and

speed of CPU, type and amount of memory for each memory slot,

BIOS revision level, types of add-in PCI boards and components,

certain revision numbers of hardware installed, etc. are automatically

detected and stored in the DMI pool, which is a par t of the system

board's Plug and Play BIOS. Additional information, such as ISA

based peripherals, which may not be automatically detected, can be

manually recorded in the DMI pool by using the Add DMI menu.

The DMI pool data is then verified or updated whenever the system

hardware or setup is altered.

4.1.1 Running the DMI Utility

To run the DMI utility, type: DMICFG.EXE. You can download this

utility from http://www.dfiweb.com - BIOS & DRIVERS section or

ftp.dfiusa.com - /pub/DMI directory.

The DMI utility must run in real mode with at least 180K of base

memory. Memory managers like HIMEM.SYS (required by Windows)

must not be installed. You may do this by using one of the 3

methods listed below.

1. Boot up from a system diskette without the AUTOEXEC.BAT

and CONFIG.SYS files,

2. REM HIMEM.SYS in the CONFIG.SYS, or

3. Press <F5> during bootup to bypass your AUTOEXEC.BAT and

CONFIG.SYS files.

by this monitor.

The screen seems to be constantly wavering.

1. If the monitor is close to another monitor, the adjacent monitor

may need to be turned off. Fluorescent lights adjacent to the

monitor may also cause screen wavering.

Power Supply

When the computer is turned on, nothing happens.

1. Check that one end of the AC power cord is plugged into a live

outlet and the other end properly plugged into the back of the

system.

2. Make sure that the voltage selection switch on the back panel is

set for the correct type of voltage you are using.

3. The power cord may have a shor t or open. Inspect the cord

and install a new one if necessary.

Floppy Drive

The computer cannot access the floppy drive.

1. The floppy diskette may not be formatted. Format the diskette

and try again.

2. The diskette may be write-protected. Use a diskette that is not

write-protected.

3. You may be writing to the wrong drive. Check the path

statement to make sure you are writing to the targeted drive.

4. There is not enough space left on the diskette. Use another

diskette with adequate storage space.

Hard Drive

Hard disk failure.

1. Make sure the correct drive type for the hard disk drive has

been entered in the BIOS.

2. If the system is configured with two hard drives, make sure the

bootable (first) hard drive is configured as Master and the

second hard drive is configured as Slave. The master hard drive

must have an active/bootable partition.

Excessively long formatting period.

1. If your hard drive takes an excessively long period of time to

format, it is likely a cable connection problem. However, if your

hard drive has a large capacity, it will take a longer time to

format.

Parallel Port

The parallel printer doesnt respond when you try to print.

1. Make sure that your printer is turned on and that the printer is

on-line.

2. Make sure your software is configured for the right type of

printer attached.

3. Verify that the onboard LPT ports I/O address and IRQ settings

are configured correctly.

4. Verify that the attached device works by attaching it to a parallel

port that is working and configured correctly. If it works, the

printer can be assumed to be in good condition. If the printer

remains inoperative, replace the printer cable and try again.

Serial Port

The serial device (modem, printer) doesnt output anything or is

outputting garbled characters.

1. Make sure that the serial devices power is turned on and that

the device is on-line.

2. Verify that the device is plugged into the correct serial port on

the rear of the computer.

3. Verify that the attached serial device works by attaching it to a

serial port that is working and configured correctly. If the serial

device does not work, either the cable or the serial device has a

problem. If the serial device works, the problem may be due to

the onboard I/O or the address setting.

4. Make sure the COM settings and I/O address are configured

correctly.

Keyboard

Nothing happens when a key on the keyboard was pressed.

1. Make sure the keyboard is properly connected.

2. Make sure there are no objects resting on the keyboard and

that no keys are pressed during the booting process.

System Board

1. Make sure the add-in card is seated securely in the expansion

slot. If the add-in card is loose, power off the system, re-install

the card and power up the system.

2. Check the jumper settings to ensure that the jumpers are

properly set.

3. Verify that all memor y modules are seated securely into the

memory sockets.

4. Make sure the memory modules are in the correct locations.

5. If the board fails to function, place the board on a flat surface

and seat all socketed components. Gently press each component

into the socket.

6. If you made changes to the BIOS settings, re-enter setup and

load the BIOS defaults.
