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 memor y. 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.

disk drives. To prevent improper IDE

cable installation, each shrouded PCI

IDE header has a keying mechanism.

The 40-pin connector on the IDE

cable can be placed into the header

only if pin 1 of the connector is

aligned with pin 1 of the header.

Hardware Installation

Note:

An IDE cable with a standard 40-pin connector (without the

keying mechanism) can be installed in the shrouded IDE

header. Be extremely careful to match the colored edge of the

ribbon with pin 1 of the header.

Page 32

P2XLX System Board Users Manual

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 J8). 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 J7).

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.

Page 33

Hardware Installation

To use an IDE drive, you need to enter the drive type (this

information is provided by the drive manufacturer) into the systems

CMOS setup table. Then run FDISK and FORMAT provided with

your operating system. You may also use the IDE HDD Auto

Detection function which will allow the BIOS to auto detect your

hard drive type. Refer to the Chapter 3 - IDE HDD Auto Detection

section for details.

Warning:

Do not run FDISK and FORMAT programs on a drive that has

already been formatted or you will lose all programs and data

stored on 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.

Page 47

Award BIOS Setup Utility

CPU L1 Cache and CPU L2 Cache

These categories speed up the memory access. The default value is

enabled. Enable the External Cache for better performance.

Quick Power On Self Test

This category speeds up Power On Self Test (POST) after you power

on your system. When Enabled, the BIOS will shorten or skip some

check items during POST.

Boot Sequence

This category determines which drive to search first for the disk

operating system. The default is A, C, SCSI. The options are:

A, C, SCSI; C, A, SCSI; C, CDROM, A; CDROM, C, A;

D, A, SCSI; E, A, SCSI; F, A, SCSI; SCSI, A, C;

SCSI, C, A; C only; LS120/ZIP, C.

Swap Floppy Drive

When this option is enabled and the system is booting from the floppy

drive, the system will boot from drive B instead of drive A. When this

option is disabled and the system is booting from the floppy drive, the

system will boot from drive A. You must have two floppy drives to

use this function.

Boot Up Floppy Seek

When enabled, the BIOS will check whether the floppy disk drive installed

is 40 or 80 tracks. Note that the BIOS cannot distinguish between 720K,

1.2M, 1.44M and 2.88M drive types as they are all 80 tracks. When

disabled, the BIOS will not search for the type of floppy disk drive by

track number. Note that there will not be any warning message if the drive

installed is 360KB.

Boot Up NumLock Status

This allows you to determine the default state of the numeric keypad.

By default, the system boots up with NumLock on wherein the function

of the numeric keypad is the number keys. When set to Off, the

function of the numeric keypad is the arrow keys.

Gate A20 Option

This entry allows you to select how gate A20 is handled. Gate A20

is a device used to address memory above 1 Mbyte. Initially, gate A20

was handled via the keyboard controller. Today, while keyboards still

provide this support, it is more common, and much faster, for the

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

to report that the key has been depressed repeatedly. For example,

you would use such a feature to accelerate cursor movements with

the arrow keys.

Typematic Rate (Chars/Sec)

This selection allows you to select the rate at which the keys are

accelerated.

Current CPU Temperature, Current CPU Fan Speed and Current

Chassis Fan Speed

These fields show the current temperature of the processor, and the

current fan speed of the CPU and chassis fans in RPM (Revolutions

Per Minute).

CPU Temperature Limit

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

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

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

a power supply are:

Page 52

- The power supply is not functioning normally. Turn off your

system and replace the power supply.

- The AC input from the power outlet to your system is unstable.

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 ser vice 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 memor y 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 part 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 director y.

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.

B.1 Troubleshooting Checklist

This chapter of the manual is designed to help you with problems

that you may encounter with your personal computer. To efficiently

troubleshoot your system, treat each problem individually. This is to

ensure an accurate diagnosis of the problem in case a problem has

multiple causes.

Some of the most common things to check when you encounter

problems while using your system are listed below.

1. The power switch of each peripheral device is turned on.

2. All cables and power cords are tightly connected.

3. The electrical outlet to which your peripheral devices are

connected is working. Test the outlet by plugging in a lamp or

other electrical device.

4. The monitor is turned on.

5. The displays brightness and contrast controls are adjusted

properly.

6. All add-in boards in the expansion slots are seated securely.

7. Any add-in board you have installed is designed for your system

and is set up correctly.

Monitor/Display

If the display screen remains dark after the system is turned on:

1. Make sure that the monitors power switch is on.

2. Check that one end of the monitors power cord is properly

attached to the monitor and the other end is plugged into a

working AC outlet. If necessary, try another outlet.

3. Check that the video input cable is properly attached to the

monitor and the systems display adapter.

4. Adjust the brightness of the display by turning the monitors

brightness control knob.

The picture seems to be constantly moving.

1. The monitor has lost its vertical sync. Adjust the monitors vertical

sync.

2. Move away any objects, such as another monitor or fan, that

may be creating a magnetic field around the display.

3. Make sure your video cards output frequencies are supported

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.

Troubleshooting

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 por t 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 memory modules are seated securely into the

memory sockets.

4. Make sure the SIMMs 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.
