Hardware SetupHardware Setup

If your mainboard has already been installed in your computer you may still need

to refer to this chapter if you plan to upgrade your system's hardware.

Be sure to disconnect the power cable from the power source before performing

any work on your mainboard, i. e. installing a CPU, memory module, changing

a jumper setting, etc. Not doing so may result in electrical shock!

2-1 Introduction to Jumpers

Jumpers are used to select between various operating modes. A jumper consists of

a row of gold colored pins that protrude from the surface of the mainboard. It is

important not to confuse jumpers with connectors or headers.

Putting jumper caps on anything that is not a jumper may result in damaging

your mainboard. Please refer to Section 1-3, Mainboard Layout, for the location

of jumpers on your mainboard.

As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting

in shorting those pins that it covers. If the cap is removed from the top of the pins,

the jumper is left "open." The number 1 shown both in the diagram below and in

all multiple pin jumper and header diagrams in this manual indicates the pin designated

with the number 1. The numbering of the remaining pins follows in sequence.

2-2 Installing a PGA type CPU in a ZIF Socket

The Intel Socket 7, designed for the Pentium processor, has been incorporated as

a standard mainboard specification and is compatible with AMD and Cyrix CPUs. To

insert your CPU into Socket 7 please do the following:

1. Locate a small dot marked on the top surface of the CPU close to one if it's

corners. The same corner will also be cut off, leaving a noticeable notch in the

CPU's corner. These markings indicate Pin 1 of the CPU. See Figure 2-2.

Figure 2-2 The markings on top of a CPU

2. Pull up the lever of Socket 7 so that it is perpendicular with the surface of the

mainboard. Gently insert the CPU with Pin 1 at the same corner of Socket 7 that

contains the end of the lever. Allow the the weight of the CPU to push itself into

place. Do not apply extra pressure as doing so may result in damaging your CPU.

Snap the lever back into place. See Figure 2-3.

Installing a heat sink and cooling fan on top of your CPU is necessary for

proper heat dissipation. Failing to install these items may result in overheating

and possible burn-out of your CPU.

Overclocking

Operating a CPU at a higher frequency than its specification allows is called overclocking.

If the CPU frequency is set at a higher frequency than its specification allows, it may

or may not run at that freqency, depending on the quality of your CPU and the extent

to which the frequency has been overset. The mainboard manufacturer highly

discourages overclocking as it may result in data loss, CPU burn-out, system failure,

etc.

Many processors are frequency locked processors and are not able to perform

overclocking. Regardless of whether the processor is a frequency locked, overclocking

may cause some processors to hang when turning on the system. When the processor

hangs, the screen remains blank and the system does not boot. To solve this problem,

do the following:

1. Turn off the computer and then press the Home key on your keyboard

2. Turn on your computer, wait for five seconds and then release the Home key.

(Pressing the Home key allows the computer to boot at a low system speed.

For example, 100MHz external clock CPUs boot-up at 133MHz.)

3. Enter BIOS and reconfigure your CPU parameters as described in this section.

Voltage ConfigurationVoltage Configuration

Voltage Configuration

Voltage ConfigurationVoltage Configuration

There are two major processor types in general

use--single and dual voltage processors. Most

single voltage processors such as Pentium,

AMD-K5, and Cyrix 6x86 processors use a

single voltage value of 3.5v for both core and

I/O voltage settings. Most dual voltage

processors such as Pentium processors with

MMX technology and Cyrix 6x86L

processors use a dual voltage value of 2.8v

for core and 3.3v for I/O voltage settings. To

make the voltage setting for single and dual

voltage processors, simply set JP10according

to the table on the next page. The voltage

2-4 Connector and Jumper Settings

Connectors are used to link the system board with other parts of the system, including

the power supply, the keyboard, and the various controllers on the front panel of

the system case.

The power supply connector is the last connection to be made while installing a

mainboard. Before connecting the power supply, please make sure it is not

connected to the power source.

ATX Power Supply Connector

JP9

This mainboard requires a power supply of at least 200

watts. The power cord leading from the system's

power supply to the external power source must be

the very last part connected when assembling a system.

The ATX power supply provides a single 20-pin connector

interface which incorporates standard +/-5V, +/-12V,

optional 3.3V and Soft-power signals. The Soft-power

signal, a 5V trickle supply is continuously supplied when

AC power is available. When the system is in the Soft-

Off mode, this trickle supply maintains the system in it's

minimum power state.

Software Power-Off Control

This mainboard can be powered down using theWindows 95 Software Power-Off

function. To power down your computer, click the START button on the Windows 95

Task Bar. Select "Shut Down The Computer" and the system turns off. The message

"It is now safe to turn off your computer" will not be shown when using this function.

Power-On By ModemPower-On By Modem

A. Over-ride Power Button Connector

The power button on the ATX chassis can be used as a

normal power switch as well as a button to activate Advanced

Power Management Suspend mode. This mode is used for

saving electricity when the computer is not in use for long

periods of time. The Soft-OFF by PWR-BTTN function

in BIOS's Power Management Setup menu must be set to

"Delay 4 Sec." to activate this function. (See section 3-4)

When the Soft-OFF by PWR-BTTN function is enabled,

pushing the power button rapidly will switch the system to

Suspend mode. Any occurence of external activity such as

pressing a key on the keyboard or moving the mouse will

bring the system back to Full-On. Pushing the button while

in Full-On mode for more than 4 seconds will switch the

system completely off. See Over-ride Power Button

Operation diagram.

B. Keyboard Lock & Power Indicator LED Connector

Plugging this connector into the lock on the front panel

of the system case allows the lock to enable or disable

the keyboard. This function provides limited security

against casual intruders. The power indicator LED shows

the system's power status. It is important to pay attention

to the correct cable and pin orientation (i.e., not to reverse

the order of these two connectors.)

C. Green Switch/Green LED Connector

Some ATX cases provide a Green switch which is used

to put the system in Suspend mode. In Suspend mode,

the power supply to the system is reduced to a trickle,

the CPU clock is stopped, and the CPU core is in its

minimum power state. The system is woken up whenever

the keyboard or mouse is touched. The system resumes

in different ways as defined by Power Management Setup

screen in BIOS.

D. System Reset Switch Connector

This connector should be connected to the reset switch

on the front panel of the system case. The reset switch

allows you to restart the system without turning the

fans with minimum of 3500 RPM. The wiring and plug

may vary depending on the manufacturer. On standard

fans, the red is positive (+12V), the black is ground, and

the yellow wire is the rotation signal.

FAN3 (Case Fan) is an independent power line that

is not control by system health monitor and power

management.

WOL (Wake-on-LAN) Connector (CN5)

JP9

Enable the Wake Up On LAN selection in BIOS's Power

Management Menu to use this function. The capability

to remotely manage PCs on a network is a significant

factor in reducing administrative and ownership costs.

Magic Packet technology is designed to give WOL (Wake-

on-LAN) capability to the LAN controller. When a PC

capable of receiving wake up command goes to sleep, the

Magic Packet mode in the LAN controller is enabled.

When the LAN controller receives a Magic Packet frame,

the LAN controller will wake up the PC. This header is

used to connect an add-in NIC (Network Interface Card)

which gives WOL capability to the mainboard.

To support this function, a switching power supply

with a minimum of 750mA 5VSB is required.

Hard Disk Setup (Primary/Secondary; Master/Slave)

This category identifies up to four IDE hard disk drives that have been installed in

the computer. This section does not show information on other IDE devices such

as CD-ROM drives or other hard drive types such as SCSI drives.

Page 21

Award BIOS Setup Program

Type (Auto/User/None): Use the fields under the Type column to determine the method

you will use to configure the IDE devices. If you choose Auto, BIOS will automatically

detect and make optimal settings for most IDE hard drives.

The mainboard manufacturer recommends that you choose Auto for all

drives.

Choose User to define your own drive type manually. You must enter values indicated

in the table below into each drive parameter field. This information should be included

in the documentation from your hard disk vendor or system manufacturer:

TYPE Setting method

CYLS Number of cylinders

HEAD Number of heads

PRECOMP Write precompensation cylinder

LANDZ Landing zone

SECTOR Number of sectors

MODE Mode type

Table 3-1 Hard Disk Drive Parameters

Cyls/Head/Sector: The number of Cylinders, Heads, and Sectors can usually be found

written on the top of the hard disk. If you have a relatively new hard drive, entering

this information alone is usually sufficient for normal hard disk operation. The hard

disk will not work properly if you enter improper information for these categories.

Precomp: Older hard drives (i.e., MFM or RLL drives) have the same number of sectors

per track at the innermost tracks as at the outermost tracks. Thus, the data density

at the innermost tracks is higher and the bits are lying closer together. Even though

the physical size of a sector gets progressively smaller as the track diameter diminishes,

each sector must still hold 512 bytes. Write precompensation circuitry compensates

for the difference in sector size by boosting the write current for inner track sectors.

Landz: This defines the address of the landing zone and is only used for older hard

drives which do not have an auto-parking feature.

Mode: If the Type value is not None for any device, you must set the Mode value

for that device. There are four different Mode values: Auto, Normal, Large, and

LBA.

Auto - BIOS detects and enters the IDE drive type during bootup.

Normal - for IDE drives that meet the old IDE specification which support a

maximum capacity of 528MB (1024 cylinders, 16 heads, and 63 sectors).

Large - for IDE drives that do not support LBA and have more than 1024

cylinders. Try this setting if your hard disk does not operate properly with

Page 22

Chapter 3

the LBA setting. Large mode is not supported by all operating systems, i.e.,

only certain versions of DOS support large mode.

LBA - (Large/Logical Block Addressing) With LBA, the IDE controller

transforms the data address described by sector, head, and cylinder number

into a physical block address, significantly improving data transfer rates. This

mode is for drives with greater than 1024 cylinders and between 528MB and

8.4GB in size. This protocol is the current common standard.

Choose None for Type if there are no IDE HDD devices in your system.

You can use the IDE HDD Auto Detection function to auto detect your hard

drive parameters. Using this function will automatically insert the parameters

discussed under Hard Disk Setup and will indicate User for the Field value.

Please see Section 3-9 for more information.

Floppy Disk Drives

Choose the memory capacity and disk size that corresponds with that of your floppy

disk drive(s).

Video

Select the type of video adapter present in your system. You can ignore this setting

if you are using a VGA monitor since VGA BIOS automatically configures this setting.

Halt

When the system is powered on, BIOS performs a series of diagnotic tests called

POST (Power On Self Test). This function stops the computer if BIOS detects a

hardware error. You can tell BIOS to halt on all errors, no errors, or not to halt on

specific errors.

A. Virus Protection

Anti-Virus Protection

This is an anti-virus code incorporated in the mainboard's BIOS firmware. During

the boot-up sequence, BIOS loads before loading of the partition table or boot

sector. The anti-virus code loads with BIOS and is able to detect boot-up viruses

before they have a chance to infect the hard drive. This function employs rule-

based logic that doesn't look for specific viruses but rather detects patterns found

in every virus, eliminating the need to perform periodical version updates after

new viruses have been found.

B. Cache Control

CPU Internal Cache/External Cache

Cache memory is much faster than conventional DRAM system memory. These

fields allow you to enable or disable the CPUs Level 1 built-in cache and Level

Page 24

Chapter 3

2 external cache. Both settings are left enabled to significantly increase the

performance of your computer.

C. Boot Up Features

After turning on the system, BIOS will perform a series of device initializations

and diagnostic tests discussed below.

Quick Power On Self Test (POST)

Enable this function to reduce the amount of time required to run the POST

(Power On Self Test). BIOS saves time by skipping some items during POST.

It is recommended that you disable this setting. Discovering a problem during

bootup is better than loosing data during your work.

Boot Sequence

This option sets the sequence of drives BIOS attempts to boot from after POST

completes. BIOS will search these drives for an operating system.

Swap Floppy Drive

Enabling this function will swap the floppy drive assignment so that drive A

will function as drive B, and drive B will function as drive A. Note that the

boot sequence assignment mentioned directly above does not inlcude booting

from floppy drive B. This function is useful if floppy drives B and A are of

a different format and you want to boot from floppy drive B.

Boot up Floppy Seek

During POST, BIOS will determine if the installed floppy disk drive has 40

or 80 tracks. A 360K drive has 40 tracks and 720K, 1.2M and 1.44M drives

have 80 tracks. All modern floppy disk drives have 80 tracks.

Boot Up NumLock Status

This function defines the keyboard's numberpad as number keys or arrow keys.

D. Memory Parity/ECC Check

Enable this function to perform ECC (Error Check and Correct). ECC detects and

corrects single-bit errors while it only detects double bit errors. Certain SDRAM

modules have ECC capability. For more information on SDRAM, see Section 2-

5 in this manual.

E. Keyborad Interface

Typematic Rate Setting

When enabled, you can set the following two typematic control items. When

disabled, keystrokes are determined arbitrarily by the keyboard controller in

your system.

Page 25

Award BIOS Setup Program

Typematic Rate (Chars/Sec)

The typematic rate sets the rate at which characters on the screen repeat when

a key is pressed and held down.

Typematic Delay (Msec)

The typematic delay sets how long after you press a key that a character begins

repeating.

F. Security Option

The Supervisor and/or User Password functions shown in Figure 3-1 must be set

to take advantage of this function. See Section 3-8 for password setting information.

When the Security Option is set to System, a password must be entered to boot

the system or enter the BIOS setup program. When the Security Option is set

to Setup, a password is required to enter the BIOS setup program.

G. PCI/VGA Palette Snoop

Some non-standard VGA cards or MPEG video cards may not show colors

properly. Setting this function to Enabled can correct this problem.

H. OS Select (For DRAM > 64MB)

If your system's DRAM is larger than 64MB and you are running OS/2, select

OS/2 as the item value. Otherwise, set the item value to Non-OS/2 for all other

operating systems.

I. Shadow Memory

Software such as system BIOS, video BIOS, SCSI BIOS, etc that resides in ROM

(Read Only Memory) chips is called firmware. Shadowing of firmware occurs

when BIOS is copied to RAM address C0000h through DFFFFh. Video BIOS

loads into the C0000-C7FFF memory area when video shadowing is enabled. If

an expansion peripheral in your system contains ROM-based firmware, you need

to know the address range the ROM occupies to shadow it into the correct area

of RAM.

Shadowing improves the firmware's performance because the firmware can be

read by the CPU through the 16- or 32-bit DRAM bus as opposed to the 8-bit

XT bus. However, shadowing also results in reducing the amount of high memory

(640 KB to 1 MB) for loading device drivers. Shadowing is used mostly for

ROM chips on ISA cards and not for PCI cards. Shadowing and playing games

at the same time may result in system instability as some games access the RAM

memory area being shadowed.

Explanation of the DRAM timing and chipset features setup is lengthy, highly

technical and beyond the scope of this manual. Below are abbreviated descriptions

of the functions in this setup menu. You can look on the world wide web

for helpful chipset and RAM configuration information including AWARD's

web site at http://www.award.com.

A. Cache Timing

Select Fast for a secondary cache of one bank, select Fastest for a secondary

cache of two banks.

B. Video BIOS Cacheable

Enabling this function allows caching of the video BIOS ROM at C0000h-C7FFFh,

resulting in better video performance. However, if any program writes to this

memory area, a system error may result. Caching the video BIOS results in better

performance than shadowing the video BIOS as discussed in Section 3-2.

Page 27

Award BIOS Setup Program

C. System BIOS Cacheable

Enabling this function allows caching of the system BIOS ROM at F0000h-FFFFFh,

resulting in better system performance. However, if any program writes to this

memory area, a system error may result. Caching the system BIOS results in better

performance than shadowing the system BIOS as discussed in Section 3-2.

D. Memory Hole at 15MB Addr.

Enabling this feature will reserve the 15MB to 16MB memory address space for

ISA expansion cards. However, enabling this function will result in not allowing

the system to have access to memory above 16MB. Please note that some

expansion cards require this setting to be enabled. The default setting is Disabled.

E. AGP

This function must be enabled when using an AGP card. If you disable this function

you can still use an AGP card. However, the AGP card will only have PCI card

performance.

F. AGP Aperture Size

This function determines the amount of system memory that is given to the AGP

card. Options range from 4MB to 256MB. This is a dynamic memory allotment

in that the AGP card will only use the amount of memory that it needs. The

remaining memory not in use will be available for the system to use. For example,

if 16MB is alloted to the AGP card and the card only needs 8MB, the remaining

8MB will be available for system use.

G. AGP-2X Mode

Enable this setting to utilize the 2X mode (twice as fast as 1X) offered by advanced

AGP cards. Your VGA card must support 2X mode in order to take advantage

of the faster speed.

H. Flash BIOS Protection

The mainboard manufacturer developed BIOS protection technology that protects

the System BIOS from accidental corruption by unauthorized users or computer

viruses. When enabled, the BIOS data cannot be changed when attempting to update

BIOS with the the FLASH utility. When disabled, the BIOS data can be updated

by using the FLASH utility.

I. System Monitoring and Alerting (Optional)

These optional system health monitoring features are available when an EISCA

v1.0 compliant fan is connected to the Fan 78 connector on your mainboard.

Change the CPU warning temperature according to the specifications of your CPU.

For more information about EISCA fans, see Apendix II of this manual.

A. Advanced Configuration Power Interface (ACPI)

ACPI management enables the operating system to control the amount of power

given to each device attached to the computer. With ACPI, the operating system

can turn off peripherals devices, such as CD-ROM players, when they are not

in use.

B. Power Management

Power management allows the computer to save electricity when it is not in use

by entering increasingly deep power saving modes as shown by the diagram below.

Power Saving Mode Flow Chart

Page 29

Award BIOS Setup Program

The computer runs in Normal operation mode until the Doze timer expires, at which

point the computer enters Doze mode. If no external activity occurs, the computer

will go into Standby and Suspend modes when their respective timers expire. If

external activity occurs, the computer will wake up from Power Management and

return to Normal mode. To activate the function, set Power Management to

Maximum Saving, User Define, or Minimum Saving described

below. For a description of the power saving modes (Doze, Standby, and

Suspend) see their descriptions below.

Disabled - Turns off the Power Management functions.

Max. Saving - All timers are set at the minimum value of one minute to

maximize power saving.

Min. Saving - All timers are set at the maximum value of one hour for

minimal power saving.

User Define - User can configure the timer to a desired time according to

the values available.

Note that enabling the Power Management function will result in enabling the

HDD Power Down function (Max Saving = 15 min, Min Saving = 1 min). The

HDD Power Down function is not part of the Power Management scheme as

indicated in Figure 3-6 Refer to the Standby Mode, Suspend Mode, and HDD

Power Down descriptions below for more informaiton on hard drive power

management.

C. PM Control by APM

This function allows software other than BIOS to control Power Management

features Enable this function in BIOS and make sure APM (Advanced Power

Management) is present. For example, run the Power utility program located

in the DOS directory, C:\DOS\POWER.EXE to use Power Management features

under DOS. For Windows 3.1x and Windows 95, you need to install Windows

with the APM feature.

D. Video Off Option

This setting determines when the monitor enters power saving mode. As the

function name indicates, the monitor enters the power saving mode after the chosen

event expires. The Power Management function must be enabled to use this

function.

E. Video Off Method

This function serves as both a screen saver and power saver for monitors.

See the next function, Video Off After, for setting the video timer.

Page 30

Chapter 3

Blank - BIOS will only blank the monitor's screen. The electricity saved in

this mode is negligible and this function is only used as a screen saver to

prevent screen damage while the screen is on but not in use.

V/H SYNC+Blank - The system turns off the vertical and horizontal syn-

chronization ports, writes blanks to the VGA buffer and the monitor's electron

gun turns off. This function requires a monitor with Green features in order

to take advantage of the power saving function. If you enable this function

and do not have a Green monitor, the result will be the same as if you had

selected Blank. This function serves as both a screen saver and an electricity

saver.

DPMS Supported - Select this option if your video card supports the Display

Power Management Signaling (DPMS) standard (i.e., you have a monitor that

supports Green features). Use software supplied by your video subsystem

to set video power management options.

F. Modem Use IRQ

If your computer has a modem, use this function to tell BIOS which IRQ is being

occupied by the modem card. When the system is in Green mode, the modem

requires an IRQ assignment to wake up the system and perform tasks. This

assignment is compliant with the APM 1.2 specification and is to be used in

coordination with APM 1.2 compliant operating systems.

G. Soft-Off by PWRBTN

When Enabled, this function allows the power button to put the system in Suspend,

a power saving mode. See section 2-4 for operation instructions of the power

button.

H. HDD Power Down

To enable this function, make sure the Power Management function is not set

to disabled. When the HDD idle time has elapsed, BIOS sends a command to

the hard disk to turn off the motor. Set a time between 1 and 15 to indicate

time required to wait before the hard drive enters a power saving mode. Some

old hard drives may not support this function.

I. CPUFAN Off in Suspend

When Enabled, the CPU fan turns off during Suspend mode.

Page 31

Award BIOS Setup Program

J. HDD Power Down

The Power Management function must not be set to disabled to enable this

function. When the HDD idle time has elapsed, BIOS sends a command to the

hard disk to turn off the motor. Set a time between 1 and 15 to indicate time

required to wait before the hard drive enters a power saving mode. Some old

hard drives may not support this function.

K. Doze Mode

To enable this function, make sure the Power Management function is not set

to disabled. If no interrupts have occured and the Doze timer expires, system

will enter Doze mode. In Doze mode, the CPU clock runs at a lower speed while

all other devices operate normaly.

Power saving modes achieved in lower power saving states will either be

maintained or enter higher power saving modes when switching to higher power

saving states. For example, the CPU clock will not switch back to normal

in Standby mode. It will maintain a decreased rate in Standby Mode and turn

off in Suspend Mode.

L. Suspend Mode

To enable this function, make sure the Power Management function is not set

to disabled. If the system runs in Dozemode and the Suspend timer expires, all

devices regulated by power management will shut off and the CPU speed will

be 0 MHz.

M. Power On By Modem

When enabled, a modem that receives a call will wake up the system from Soft-

off or Green mode. To activate this function, you must leave your modem on

and use the Software Power off. See the Software Power-Off control description

in Section 2-4 of this manual.

N. Power On By Alarm

When enabled, this setting allows the system to turn back on at a designated

time of the month. User must designate date of month and time of day. This

function is only available when using an ATX pwer supply and Software Power-

Off. See the Software Power-Off control description in Section 2-4 of this manual.

of the configuration data structures stored in flash memory. Each data

structure defines the resources used by a device or a card in the system.

This includes legacy and PCI/ISA PnP devices.

Page 33

Award BIOS Setup Program

C. Reset Configuration Data

When Enabled the system BIOS will clear/reset the ESCD during POST. After

clearing the ESCD, the BIOS will then change this item's value to "Disabled."

Otherwise, the ESCD data would become useless.

D. IRQ#/DMA# assign to

When resources are controlled manually, you can assign each system interrupt

& DMA channel for "Legacy ISA" or "PCI/ISA PnP" card used. While using Legacy

ISA Cards (non-PnP ISA cards), please set the necessary corresponding resources

(INT#, DMA#) from "PCI/ISA PnP" to "Legacy ISA."

@ All ISA non-PnP devices are legacy devices that select resources (I/O Addr.,

INT# or DMA#) by using hardware jumpers on these devices.

@ IRQ-3/4/7/12/14/15 have been set as default for on board devices

(COM2,COM1, Printer port, PS/2 mouse, IDE1 and IDE2).

E. CPU to PCI Write Buffer

When Enabled, CPU to the PCI bus are buffered, to compensate for the speed

differences between the CPU and the PCI bus.

F. PCI Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delay

transactions cycles. Select Enabled to support compliance with PCI specification

version 2.1.

G. FDD IRQ Can Be Free

This function allows users to choose if the FDD IRQ is able to be freed for use with

other processes that require IRQ.

H. Assign IRQ For USB

If USB is employed this function must be Enabled. Otherwise, disable this function

to optimize Windows 95 IRQ resources for other IRQ usage. N/A (disabled.)

I. Assign IRQ For VGA

This function allows BIOS to make an IRQ available to VGA cards. Current VGA

card models do not require this function to be enabled.

3-8 Supervisor Password & User Password Setting

There are four different variables that control password settings. The first two are

located under the Security Option function in BIOS Features Setup Menu (Figure

3-3). When the Security Option function is set to Setup, a password is required to

enter BIOS and change BIOS settings. When the Securitiy Option function is set

to System, a password is required to to enter both BIOS and the the computer's

operating system (for example Windows 95) found on the boot drive. This is shown

in Figures 3-9 and 3-10.

The third and fourth variables are user password and supervisor password selected

in BIOS (Figure 3-1). The main purpose of separating user and supervisor is to allow

only the supervisor to have control over the settings in BIOS. The user, on the other

hand, is only allowed to access the computer's operating system and change the user

passorword in BIOS (See Figure 3-10 ). Note that when there is no supervisor password

set, the user password controls access to all BIOS settings (See Figure 3-9 below).
