Chapter 1: Introduction

1-2 Chipset Overview

The Intel Grantsdale (915G) chipset contains two primary components: the Graphics

Memory Controller Hub (GMCH) and the I/O Controller Hub (ICH6). The Grantsdale

(915G) provides the performance and feature-set required for high-end single-pro-

cessor desktop solutions.

Graphics Memory Controller Hub (GMCH)

The function of the GMCH is to manage the data fl ow between fi ve interfaces: the

CPU interface Front Side Bus (FSB), System Memory Interface (DRAM controller),

PCI Express Graphic Interface, I/O Controller and the Direct Media Interface (DMI).

The GMCH is optimized for the Prescott Processors in an LGA775 Package. It

supports one or two channels of unbuffered, non-ECC DDR 400/333 SDRAM. It

also supports the PCI-Express-based external graphics solutions.

The ACPI component provides the data buffering and interface arbitration required

for the system to interface effi ciently. The Direct Media Interface (DMI) is a point-

to-point interconnection between the Grantsdale GMCH and the ICH6. Virtually

all communication between the GMCH and the ICH occurs over the Direct Media

Interface. DMI supports 2GB/s (IGB/s each direction) of bandwidth, using a 100

MHz differential clock.

Intel ICH6 System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest of the

system. Functions and capabilities include:

*PCI Express Base Specifi cation, Rev. 1.0a-compliant

*PCI 2.3

*ACPI Power Management Logic Support

*USB host interface

*Enhanced DMA Controller

*System Management Bus

*Low Pin Count (LPC) Interface

*Firmware Hub (FWH) Interface

Graphics Features/Display

The Grantsdale GMCH provides an integrated graphics accelerator, delivering 3D,

2D and video capabilities. It also provides interfaces to a progressive scan analog

monitor and two DVO devices. It is compliant with DVI specifi cation and has a

high-speed interface to a digital display.

P8SGA User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the P8SGA. The moth-

erboard has an onboard System Hardware Monitor chip that supports PC health

monitoring.

Eight Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V, +3.3V standby, +5V, 1.5V, Vbat and ±12V

The onboard voltage monitor will scan these voltages continuously. Once a voltage

becomes unstable, it will give a warning or send an error message to the screen.

Users can adjust the voltage thresholds to defi ne the sensitivity of the voltage

monitor.

Fan Status Monitor with Firmware/Software

The PC health monitor can check the RPM status of the cooling fans via Supero

Doctor.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat monitoring in the

BIOS. This allows the user to defi ne an overheat temperature threshold. When this

temperature reaches the threshold, the CPU thermal trip feature will be activated,

and it will send a signal to the Speaker LED and, at the same time, the CPU speed

will be decreased to reduce heat dissipation.

1-4 Power Confi guration Settings

This section describes features of your motherboard that deal with power and

power settings.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake-up and the LED will automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, the keyboard will function

like a normal keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button. When the user presses the power button, the system will enter

1-10

Chapter 1: Introduction

a SoftOff state. The monitor will be suspended and the hard drive will spin down.

Pressing the power button again will cause the whole system to wake-up. During

the SoftOff state, the ATX power supply provides power to keep the required circuitry

in the system "alive." In case the system malfunctions and you want to turn off the

power, just press and hold the power button for 4 seconds. The power will turn off

and no power will be provided to the motherboard.

Wake-On-Ring (WOR) Header

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the SoftOff state. Note that external modem ring-on can only

be used with an ATX 2.01 (or above) compliant power supply.

1-5 Power Supply

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates of 1 GHz and faster.

The

power supplies generally meet the specifi cations required by the CPU, some are

inadequate. A 2 amps of current supply on a 5V Standby rail is strongly recom-

mended.

It is strongly recommended that you use a high quality power supply that meets

12V ATX power supply Specifi cation 1.1 or above. It is also required that the 12V

4-pin power connection (J41) be used for high-load confi gurations. In areas where

noisy power transmission is present, you may choose to install a line fi lter to shield

the computer from noise. It is recommended that you also install a power surge

protector to help avoid problems caused by power surges.

P8SGA accommodates 12V ATX power supplies. Although most

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, drive interface control logic and interrupt and DMA logic. The wide range of

functions integrated onto the Super I/O greatly reduces the number of components

required for interfacing with fl oppy disk drives. The Super I/O supports two 360

K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,

500 Kb/s or 1 Mb/s.

1-11

P8SGA User’s Manual

It also provides two high-speed, 16550 compatible serial communication ports

(UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable baud

rate generator, complete modem control capability and a processor interrupt sys-

tem. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well

as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support

higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Confi guration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.

2-1 Static-Sensitive Devices

Electric Static Discharge (ESD) can damage electronic com ponents. To prevent

damage to your system board, it is important to handle it very carefully. The following

measures are generally suffi cient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the antistatic

bag.

• Handle the board by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when not in

use.

• For grounding purposes, make sure your computer chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the motherboard.

• Use only the correct type of CMOS onboard battery as specifi ed by the Manufac-

turer. Do not install the CMOS onboard battery upside down to avoid a possible

explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

Installation Procedures

Follow the procedures as listed below to install the motherboard into a chassis:

1. Install the processor and the heatsink to the motherboard.

2. Install the motherboard in the chassis.

3. Install the memory modules and add-on cards.

4. Connect cables and install controllers/drivers.

P8SGA User's Manual

2-2 Processor and Heatsink Fan Installation

When handling the processor package, avoid placing direct pres-

!

IMPORTANT: Always connect the power cord last and always remove it before add-

ing, removing or changing any hardware components. Make sure that you install

the processor into the CPU socket before you install the CPU heatsink.

(*Note: The CPU heatsink fan is included only with the retail versions of the P8SGA.

Please note that the North Key and the

South Key are located vertically in the

CPU housing.

4. Position the motherboard in such a way

that Pin 1 of the CPU socket is located at

the left bottom of the CPU housing.

5. Use your thumb and your index fi nger to

hold the CPU at the North Center Edge and

the South Center Edge of the CPU.

6. Align Pin 1 of the CPU with Pin 1 of the

socket. Once aligned, carefully lower the

CPU straight down to the socket. (**Do not

drop the CPU on the socket. Do not move

the CPU horizontally or vertically. Do not

rub the CPU against the surface or against

any pins of the socket to avoid damage to

the CPU or the socket.)

the four corners of the CPU to make sure

that the CPU is properly installed.

8. Use your thumb to gently push the lever

down and lock it in the hook.

9. If the CPU is properly installed into the

socket, the plastic cap will be automatically

released from the load plate when the lever

is pushed into the hook. Remove the plastic

cap from the motherboard.

(*Warning: Please save the plastic cap.

The motherboard must be shipped with

the plastic cap properly installed to protect

the CPU socket pins. Shipment without

the plastic cap properly installed will cause

damage to the socket pins.)

Installation of the Heatsink

1. Locate the CPU Fan on the mother-

board. (Refer to the layout on Page 1-4

for the CPU Fan location.)

2. Position the heatsink in such a way

that the heatsink fan wires are closest to

the CPU fan and are not interfered with

other components.

3. Inspect the CPU Fan wires to make

sure that the wires are routed through

the bottom of the heatsink.

4. Remove the thin layer of the protec-

tive fi lm from the copper core of the

heatsink.

(*Warning: CPU overheat may occur if

the protective fi lm is not removed from

the heatsink.)

5. Apply the proper amount of thermal

grease on the CPU. (*Note: if your

heatsink came with a thermal pad,

please ignore this step.)

6. If necessary, re-arrange the wires

to make sure that the wires are not

pinched between the heatsink and the

CPU. Also make sure to keep clearance

between the fan wires and the fi ns of

the heatsink.

7. Align the four heatsink fasteners with

the mounting holes on the motherboard.

Gently push the fasteners into the mount-

ing holes until you hear a click.

8. Repeat Step 6 to insert all four heatsink

fasteners into the mounting holes.

2-3 Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fi t different types of chassis.

Make sure the locations of all the mounting holes for both the motherboard and the

chassis match. Although a chassis may have both plastic and metal mounting fas-

teners, metal ones are highly recommended because they ground the motherboard

to the chassis. Make sure that the metal standoffs click in or are screwed in tightly.

Then use a screwdriver to secure the motherboard onto the motherboard tray.

2-4 Installing DDR Memory

CAUTION

Exercise extreme care when installing or removing memory modules

to prevent any possible damage.

Memory Module Installation (See Figure 2-2)

1. Insert each DDR memory module vertically into its slot. Pay attention to the

notch along the bottom of the module to prevent incorrect memory installa-

tion.

2. Gently press down on the memory module until it snaps into place.

Support

The P8SGA supports Dual channel, Non-ECC, unbuffered DDR 400/333

(PC3200/2700) SDRAM. Both interleaved and non-interleaved memory

is supported, so you may populate any number of DIMM slots. (Populate

DIMM#1A,DIMM#1B, and/or DIMM#2A, DIMM#2B with memory modules

of the same size and same type will result in the dual channel, two-way

interleaved memory which is faster than the single channel, non-interleaved

memory.)

Figure 2-2. Side and Top Views of DDR Module Installation into Slot

To Install:

Insert module
vertically and
press down
until it snaps
into place.
Pay attention
to the notch.

To Remove:

Use your thumbs
gently to push

Fan Headers

There are three fan headers (Fan

1, Fan 2 and Fan3) on the P8SGA.

(See the table on the right for pin defi -

nitions.) These are 4-pin fan headers;

however, the traditional 3-wire fans

are also supported. (Pins #1-#3 of the

fan headers are backward compatible

with the traditional 3-pin fans.) When

a 3-wire fan is used, it will be set to

run at the full speed by default. When

a 4-pin fan is used, the CPU and

chassis fan speeds will be automati-

cally controlled by PWM (Pulse Width

Modulation) via Hardware Monitoring

in the BIOS.

Chassis Intrusion

The Chassis Intrusion header is lo-

cated at JL1. See the board layout

in Chapter 1 for the location of JL1

and the table on the right for pin

defi nitions.

2-7 Jumper Settings

Explanation of
Jumpers

To modify the operation of the mother-

board, jumpers can be used to choose

between optional settings. Jumpers cre-

ate shorts between two pins to change

the function of the connector. Pin 1 is

identifi ed with a square solder pad on

the printed circuit board. See the mother-

board layout pages for jumper locations.

Note: On a two-pin jumper, "Closed"

means the jumper is on both pins and

"Open" means the jumper is either on

Connector

only one pin or completely removed.

CMOS Clear

JBT1 is not actually a jumper but consists of two contact pads. To clear the

contents of CMOS, short these pads together by touching them both with a metal

conductor such as the head of a small screwdriver. Note: for ATX power supplies,

you must completely shut down the system and remove the AC power cord before

clearing CMOS.

USB Wake-Up

Use JPUSB jumpers to enable the function of System Wake-Up via USB Devices"

to allow you to wake-up the system by pressing a key on the USB keyboard or by

clicking the USB mouse on your system. The JPUSB jumpers are used together

with the USB Wake-Up function in the BIOS. Enable both the jumpers and the

BIOS setting to allow the system to use this function. See the table on the right

for jumper settings and jumper connections.

(*Note: The default setting for the USB ports is "disabled". However, when the

"USB Wake-Up" function is enabled in the BIOS and the desired USB ports are

enabled via the JPUSB jumper, please be sure to remove all USB devices from

the USB ports whose USB jumpers are set to "disabled"; otherwise, the system

will not go into the standby mode.)

2-8 Parallel, Floppy, Hard Disk, and Audio Connections

Use the following information to connect the fl oppy and hard disk drive cables.

• The fl oppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single fl oppy disk drive ribbon cable has 34 wires and two connectors to provide

for two fl oppy disk drives. The connector with twisted wires always connects to

drive A, and the connector that does not have twisted wires always connects to

drive B.

• The 80-wire ATA100/66 IDE hard disk drive cable that came with your system

has two connectors to support two drives. This special cable should be used

to take advantage of the speed this new technology offers. The blue connector

connects to the onboard IDE connector interface and the other connector(s) to

your hard drive(s). Consult the documentation that came with your disk drive

for details on actual jumper locations and settings for the hard disk drive.

Parallel Port Connector

The parallel port is located on J30.

Refer to Figure 2-3 for location. See

the table on the right for pin defi ni-

Introduction to Serial ATA (SATA)

Serial ATA(SATA) is a physical storage interface. It uses a single cable with a

minimum of four wires to create a point-to-point connection between devices. It

is a serial link which supports SATA Transfer rates from 150MBps. Because the

serial cables used in SATA are thinner than the traditional cables used in Paral-

lel ATA(PATA), SATA systems have better airfl ow and can be installed in smaller

chassis than Parallel ATA. In addition, the cables used in PATA can only extend

to 40cm long, while Serial ATA cables can extend up to one meter. Overall, Serial

ATA provides better functionality than Parallel ATA.

Introduction to the Intel ICH6 I/O Controller Hub

Located in the South Bridge of the Intel Grantsdale (915G) chipset, the ICH6 I/O

Controller Hub provides the I/O subsystem with access to the rest of the system. It

supports 2-channel Ultra ATA/100 Bus Master IDE controller (PATA) and two Serial

ATA (SATA) Host Controllers, which support up to two Serial ATA ports and up to

four hard drives. TheICH6 I/O Controller Hub supports the following Parallel ATA

(PATA) and Serial (SATA) device confi gurations:

SATA Operate Modes

You can select from the following modes: Auto, Combined, Enhanced, and SATA

Only Mode. The number of devices supported by these modes are listed below:

*SATA Only: The maximum of 4 devices are supported (4 SATA)

*Auto Mode: The maximum of 6 devices supported (4 SATA + 2 IDE)

*Enhanced Mode: The maximum of 6 devices supported (4 SATA + 2 IDE)

*Combined Mode: The maximum of 4 devices supported (2 SATA + 2 IDE)

Supero Doctor III

The Supero Doctor III program is a Web-based management tool that supports

remote management capability. It includes Remote and Local Management tools.

The local management is called the SD III Client. The Supero Doctor III program

included on the CDROM that came with your motherboard allows you to monitor

the environment and operations of your system. Supero Doctor III displays crucial

system information such as CPU temperature, system voltages and fan status. See

the Figure below for a display of the Supero Doctor III interface.

*Note 1: The default user name and password are ADMIN.

*Note 2: In the Windows OS environment, the Supero Doctor III settings take pre-

cedence over the BIOS settings. When fi rst installed, Supero Doctor III adopts the

temperature threshold settings previously set in the BIOS. Any subsequent changes

to these thresholds must be made within Supero Doctor, since the SD III settings

override the BIOS settings. For the Windows OS to adopt the BIOS temperature

threshold settings, please change the SDIII settings to be the same as those set

in the BIOS.

1. Check that the +5v standby LED is not lit (LE2 on motherboard).

2. Make sure that the 4-pin 12v power connector at J24 is connected to your

power supply.

3. Make sure no short circuits between the motherboard and chassis.

4. Disconnect all ribbon/wire cables from the motherboard, including those for the

keyboard and mouse.

5. Remove all add-on cards.

6. Install a CPU and heatsink (making sure it is fully seated) and connect the

chassis speaker and the power LED to the motherboard. Check all jumper

settings as well.

7. Use the correct type of onboard CMOS battery as specifi ed by the Manu-

facturer. Do not install the CMOS battery upside down to avoid possible

explosion.

No Power

1. Make sure no short circuits between the motherboard and the chassis.

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Turn the power switch on and off to test the system.

5. The battery on your motherboard may be old. Check to verify that it still sup-

plies ~3VDC. If it does not, replace it with a new one.

No Video

1. If the power is on but you have no video, remove all the add-on cards and

cables.

2. Use the speaker to determine if any beep codes exist. Refer to Appendix A for

details on beep codes.

3-1

P8SGA User's Manual

NOTE

If you are a system integrator, VAR or OEM, a POST diagnostics

card is recommended. For I/O port 80h codes, refer to App. B.

Memory Errors

1. Make sure the DIMM modules are properly and fully installed.

2. You should be using unbuffered DDR memory. Also, it is recommended that you

use the same memory speed for all DIMMs in the system. See Section 2-4

for memory limitations.

3. Check for bad DIMM modules or slots by swapping modules between slots and

noting the results.

4. Check the power supply voltage 115V/230V switch.

Losing the System’s Setup Confi guration

1. Make sure that you are using a high quality power supply. A poor quality power

supply may cause the system to lose the CMOS setup information. Refer to

Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

3. If the above steps do not fi x the Setup Confi guration problem, contact your

vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note

that as a motherboard manufacturer, Supermicro does not sell directly to end-us-

ers, so it is best to fi rst check with your distributor or reseller for troubleshooting

services. They should know of any possible problem(s) with the specifi c system

confi guration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked

Question' (FAQ) sections in this chapter or see the FAQs on our web site

(http://www.supermicro.com/support/faqs/) before contacting Technical

Support.

2. BIOS upgrades can be downloaded from our web site at

supermicro.com/support/bios/

).

(http://www.

Note: Not all BIOS can be fl ashed; it depends on the modifi cations to the

boot block code.

3-2

Chapter 3: Troubleshooting

3. If you still cannot resolve the problem, include the following information when

contacting Super Micro for technical support:

• Motherboard model and PCB revision number

• BIOS release date/version (this can be seen on the initial display when your

system fi rst boots up)

•System confi guration

An example of a Technical Support form is on our web site at

(http://www.supermicro.com/support/contact.cfm).

4. Distributors: For immediate assistance, please have your account number ready

when placing a call to our technical support department. We can be reached

by e-mail at [e-mail], by phone at: [phone], option

3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: The P8SGA supports up to 4 GB of non-ECC, unbuffered DDR-400/DDR

333, two-way interleaved or non-interleaved SDRAM. See Section 2-4 for details

on installing memory.

Question: How do I update my BIOS?

Answer: It is recommended that you not upgrade your BIOS if you are not experi-

encing problems with your system. Updated BIOS fi les are located on our web site

at http://www.supermicro.com/techsupport/BIOS/bios.htm. Please check our BIOS

warning message and the information on how to update your BIOS on our web site.

Also, check the current BIOS revision and make sure it is newer than your current

BIOS before downloading. Select your mainboard model and download the BIOS

fi le to your computer. Unzip the BIOS update fi le and you will fi nd the readme.txt

(fl ash instructions), the awdfl ash.exe (BIOS fl ash utility) and the BIOS image (xxxx.

bin) fi les. Copy these fi les onto a bootable fl oppy and reboot your system. Then,

follow the readme.txt to fl ash the BIOS.

Question: After fl ashing the BIOS my system does not have video. How can

I correct this?

Answer: If the system does not have video after fl ashing your new BIOS, it indicates

that the fl ashing procedure failed. To fi x this, fi rst clear CMOS per the instructions

in this manual and retry the BIOS fl ashing procedure. If you still do not have video,

please use the following BIOS Recovery Procedure. First, make sure the JPWAKE

jumper is disabled. Then, turn your system off and place the fl oppy disk with the

saved BIOS image fi le (see above FAQ) in drive A. Press and hold <Alt> and <F2>

3-3

P8SGA User's Manual

at the same time, then turn on the power keeping these keys pressed until your

fl oppy drive starts reading. Your screen will remain blank until the BIOS program

is done. If the system reboots correctly, then the recovery was successful. The

BIOS Recovery Procedure will not update the boot block in your BIOS.

Question: What's on the CD that came with my motherboard?

Answer: The supplied compact disc has quite a few drivers and programs that will

greatly enhance your system. We recommend that you review the CD and install the

applications you need. Applications on the CD include chipset drivers for Windows

and security and audio drivers.

Question: Why can't I turn off the power using the momentary power on/off

switch?

Answer: The instant power off function is controlled in BIOS by the Power But-

ton Mode setting. When the On/Off feature is enabled, the motherboard will have

instant off capabilities as long as the BIOS has control of the system. When the

Standby or Suspend feature is enabled or when the BIOS is not in control such

as during memory count (the fi rst screen that appears when the system is turned

on), the momentary on/off switch must be held for more than four seconds to shut

down the system. This feature is required to implement the ACPI features on the

motherboard.

Question: How do I utilize the six-channel sound?

Answer: The six-channel sound available on the P8SGA can be enabled with the

audio driver software that was included in your motherboard package. When acti-

vated, sound will be routed through the jacks under the Game Port as follows: Line

Out = front L&R speakers, Line In = rear L&R speakers, MIC = center and subwoofer

speakers. You must also enable the "AC97 Audio" setting in the Advanced Chipset

section of the BIOS setup.

Question: I installed my microphone correctly but I can't record any sound.

What should I do?

Answer: Go to <Start>, <Programs>, <Accessories>, <Entertainment> and then

<Volume Control>. Under the Properties tab, scroll down the list of devices in the

menu and check the box beside "Microphone".

Question: How do I connect the ATA100/66 cable to my IDE device(s)?

Answer: The 80-wire/40-pin high-density ATA100/66 IDE cable that came with

your system has two connectors to support two drives. This special cable must be

used to take advantage of the speed the ATA100/66 technology offers. Connect

the blue connector to the onboard IDE header and the other connector(s) to

your hard drive(s). Consult the documentation that came with your disk drive for

details on actual jumper locations and settings.

3-4

Chapter 3: Troubleshooting

Question: After I have installed 4 pieces of 1GB Memory, why does the BIOS

only detect about 3.145 GB of memory during POST?

Answer: Because the chipset does not support memory remapping, and PCI-e

memory requires a great deal of memory, so there is a memory hole located around

the 4GB memory address.

Question: I have already enabled the USB Wake-Up mode in the BIOS, my

system still cannot enter "Standby Mode"? Why?

Answer: When USB Wake-Up is enabled, be sure to unplug the USB devices on

the Front Panel USB ports (-USB 7/8) before entering Standby Mode.

3-4 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be-

fore any warranty service will be rendered. You can obtain service by calling your

vendor for a Returned Merchandise Authorization (RMA) number. When returning

BIOS

4-1 Introduction

This chapter describes the AwardBIOS for the P8SGA. The Award ROM BIOS

is stored in a Flash chip and can be easily upgraded using a fl oppy disk-based

program.

Note: Due to periodic changes to the BIOS, some settings may have been added

or deleted and might not yet be recorded in this manual. Refer to the Manual

Download area of our web site for any changes to BIOS that are not refl ected in

this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and

PS/2® compatible computers. The AwardBIOS Flash chip stores the system pa-

rameters, such as amount of memory, type of disk drives and video displays, etc.

CMOS requires very little power. When the computer is turned off, a back-up battery

provides power to the BIOS Flash chip, enabling it to retain the system parameters.

Each time the computer is powered-on, the computer is then confi gured with the

values stored in the BIOS ROM by the system BIOS, which gains control when the

computer is powered on.

How To Change the Confi guration Data

The CMOS information that determines the system parameters may be changed

by entering the BIOS Setup utility. This Setup utility can be accessed by pressing

<Del> at the appropriate time during system boot.

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test. As

the memory is being tested, press the <Delete> key to enter the main menu of the

BIOS Setup utility. From the main menu, you can access the other setup screens,

such as the Chipset and Power menus. Section 4-3 gives detailed descriptions of

each parameter setting in the Setup utility.
