Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the 5400 chipset, the X7DWA-N

motherboard provides the performance and feature set required for quad-core-

processor- or dual-core-processor-based high-end workstations with confi guration

options optimized for complex system platforms. The 5400 chipset supports single

or dual Intel Quad-Core/Dual-Core Xeon 5400/5300/5200/5100 Series processor

with front side bus speeds of up to 1.6 GHz. The chipset consists of the 5400

Memory Controller Hub (MCH) for the host bridge and the 631xESB/632xESB I/O

Controller Hub (Enterprise South Bridge 2-ESB2) for the I/O subsystem.

The Intel 5400 MCH (North Bridge)

The 5400 MCH (North Bridge) provides two FSB processing interfaces, four

fully buffered (FBD) DIMM memory channels, PCI-Express x4 bus interfaces

confi gurable to form x8 or x16 ports, an EB2 South Bridge Interface (ESI) and

SMBus Interfaces for system management, and DIMM Serial Presence Detect

(SPD). The PCI-Express x4 interfaces can be confi gured to form x8 or x16 ports

that can operate up to Gen-2 speeds in x16 confi guration for enhanced graphics

applications.

The Intel 631xESB/632x ESB I/O Controller Hub-ESB2 (South Bridge)

The 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2) integrates

an Ultra ATA 100 Controller, six Serial ATA host controller ports, one EHCI host

controller, six USB 2.0 ports, an LPC interface controller, and a fl ash BIOS inter-

face controller. Additionally, the ESB 2 chip also contains a PCI interface controller,

Azalia/ '97 digital controller, integrated LAN controller, an ASF controller and an

ESI for communication with the MCH. The Intel ESB2 offers the data buffering

and interface arbitration capabilities required for a high-end system to constantly

operate effi ciently and maintain peak performance.

Compliant with the ACPI platform, the ESB2 supports the Full-On, Stop-Grant,

Suspend-to-RAM, Suspend-to-Disk, and Soft-Off power management states.

Combined with the functionality offered by the onboard LAN controller, the ESB2

also supports alert systems for remote management.

With the 5400 chipset built in, the X7DWA-N offers a superb solution for intense

computing and complex I/O environments, and is ideal for high-end server sys-

tems.

X7DWA-N User's Manual

1-3 Special Features

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when

AC power is lost and then restored to the system. You can choose for the system

to remain powered off (in which case you must hit the power switch to turn it

back on) or for it to automatically return to a power- on state. See the Power Lost

Control setting in the Advanced BIOS Setup section to change the setting. The

default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DWA-N. All

have an onboard System Hardware Monitor chip that supports PC health moni-

toring.

Onboard Voltage Monitors for the CPU Cores, Chipset Voltage,
Memory Voltage, +1.8V, +3.3V, +5V, +12V, -12V, +3.3V Standby,
+5V Standby and Vbat

An onboard voltage monitor will scan these voltages continuously. Once a volt-

age becomes unstable, a warning is given or an error message is sent to the

Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard

CPU and chassis fans are controlled by Thermal Management via BIOS (under

Hardware Monitoring in the Advanced Setting).

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will

increase fan speed whenever the CPU temperature reaches a user-defi ned

threshold. The onboard chassis thermal circuitry can monitor the overall system

temperature and alert users when the chassis temperature is too high.

CPU Fan Auto-Off in Sleep Mode

When the power is turned on, the CPU fan becomes active. It stops to operate

when the system enters Standby mode. When in sleep mode, the CPU will not

run at full power, thereby generating less heat.

CPU Overheat LED

This feature is available when the user enables the CPU overheat warning function

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

When the CPU temperature reaches the user-predefi ned threshold, the warning

LED is activated.

1-10

Chapter 1: Introduction

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, if the system is running

low on virtual memory and there is insuffi cient hard drive space for saving the

data, you can be alerted of the potential problem. You can also confi gure Supero

Doctor to provide you with warnings when the system temperature goes beyond

a pre-defi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -

cation defi nes a fl exible and abstract hardware interface that provides a standard

to integrate power management features throughout a PC system, including its

hardware, operating system and application software. This enables the system

to automatically turn on and off peripherals such as CD-ROMs, network cards,

hard disk drives and printers. This also includes consumer devices connected to

the PC such as VCRs, TVs, telephones and stereos.

In addition to enabling operating system-directed power management, ACPI pro-

vides a generic system event mechanism for Plug and Play and an operating- sys-

tem-independent interface for confi guration control. ACPI leverages the Plug and

Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with Windows 2000, Windows XP, Windows

2003, Windows 2003 Servers and Windows Vista.

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 CPU is in the S1 mode,

the Power LED blinks every second. When in the S3 mode, the Power LED will

blink every 5-second. When the user presses any key, the CPU will wake-up and

the LED will automatically stop blinking and remain on.

Main Switch Override Mechanism

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

suspend button to make the system enter SoftOff state. The monitor will be sus-

pended 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

power button for 4 seconds. This option can be set in the Advanced Setup section

of the BIOS Setup routine.

1-11

X7DWA-N User's Manual

External Modem Ring-On

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.

Wake-On-LAN (WOL)

Wake-On-LAN is defi ned as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and asset

tracking can occur after hours and on weekends so that daily LAN traffi c is kept

to a minimum and users are not interrupted. The motherboard has a 3-pin header

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.

1-6 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.

The X7DWA-N can only accommodate 24-pin ATX power supplies. Although

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

are inadequate. You should use one that will supply at least 500W of power. In

addition, the 12V 4-pin power and the 12V 8-pin are also required for adequate

power supply to the system. Also your power supply must supply 1.5A for the

Ethernet ports.

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

ATX power supply Specifi cation 2.01 or above. It must also be SSI compliant

(Refer to the web site at http://www.ssiforum.org/ for more information). Addition-

ally, 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.

1-7 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

1-12

Chapter 1: Introduction

required for interfacing with fl oppy disk drives. The Super I/O supports 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. It also provides two high-speed, 16550 compatible serial com-

munication ports (UARTs). Each UART includes a 16-byte send/receive FIFO.

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 supports one PC-compatible printer port (SPP), Bi-directional

Printer Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port

(ECP).

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 an SMI or SCI function pin. It also features auto power management

to reduce power consumption.

2-1 Static-Sensitive Devices

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

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

lowing procedures 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 onboard CMOS battery as specifi ed by the

manufacturer. Do not install the onboard battery upside down to avoid 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.

2-2 Motherboard Installation

Note: Be sure to mount the motherboard into the chassis before you install the

CPU onto the motherboard.

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

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

chassis match. 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.

Note: some components are very close to the mounting holes. Please take pre-

cautionary measures to prevent damage to these components when installing the

motherboard to the chassis.

Note: Check the Supermicro web site for recommended memory modules.

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also Note that the

memory is interleaved to improve performance (see step 1).

DIMM Installation (See Figure 2-2)

1. Insert the desired number of DIMMs into the memory slots, starting with Bank

1. (Refer to the Memory Confi guration Table below for more details.)

2. Insert each DIMM module vertically into its slot. Pay attention to the notch along

the bottom of the module to prevent inserting the DIMM module incorrectly.

3. Gently press down on the DIMM module until it snaps into place in the slot.

Repeat for all modules (see step 1 above).

Memory Support

The X7DWA-N supports up to 64 GB fully buffered (FBD) ECC DDR2 800/667/533

in 8 DIMMs. Populating DIMM modules with a pair (or pairs) of memory modules

of the same type and same size will result in interleaved memory. For best per-

formance, please install (a) pair(s) of DIMM modules of the same type in both

Branch 0 and Branch 1.

ATX Power Connector

There are a 24-pin main power sup-

ply connector(JPW1) and an 8-pin

CPU PWR connector (JPW3) on

the motherboard. These power con-

nectors meet the SSI EPS 12V speci-

fi cation. The 4-pin power connectors

located at JPW2/JPW4 are also

required to provide adequate power

to the system. See the table on the

right for pin defi nitions. For the 8-pin

PWR (JPW3), please refer to the item

listed below.

High Defi nition Audio (HD Audio)

The X7DWA-N features a 7.1+2 Channel High

Defi nitio n Audio (HDA) (JC1) codecs t hat provides

10DAC channels, simultaneously supporting 7.1

sound playback with 2 channels of independent

stereo sound output (multiple streaming) through

the front panel stereo out (for front L&R, rear

L&R), center and subwoofer speakers. Use the

advanced software included in the CD-ROM with

your motherboard to enable this function. Sound

is then output through the Line In, Line Out and

MIC jacks (see the graphics at right). Enable this

feature in the BIOS to use this feature.

CD Header

A 4-pin CD header is located at CD1 and a Front

Pane Accessible Audio header is located at JC2

on the motherboard. This headers allow you to

use the onboard sound for audio CD playback.

Connect an audio cable from your CD drive to

the CD header that fi ts your cable's connector.

Only one CD header can be used at any time.

See the tables at right for pin defi nitions. (Refer

to the next page for the FP Audio.)

Front Panel Audio Control

When front panel headphones are plugged

in, the back panel audio output is disabled.

This is done through the FP Audio header

(J14). If the front panel interface card is

not connected to the front panel audio

header, jumpers should be installed on

the header (J14) pin pairs: 1-2, 5-6, and

9-10. If these jumpers are not installed,

the back panel line out connector will

be disabled and microphone input Pin

1 will be left fl oating, which can lead to

excessive back panel microphone noise

and cross talk. See the table below for

pin defi nitions.

2-7 Jumper Settings

Explanation of
Jumpers

To modify the operation of the

motherboard, jumpers can be used

to choose between optional settings.

Jumpers create 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 motherboard layout

pages for jumper locations.

Note: On two pin jumpers, "Closed"

means the jumper is on and "Open"

means the jumper is off the pins.

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads

to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such

as a small screwdriver to touch both pads at the same time to short the connection.

Always remove the AC power cord from the system before clearing CMOS.

Note: For an ATX power supply, you must completely shut down the system, remove

the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog is a system monitor that can

reboot the system when a software appli-

cation hangs. Close pins 1-2 to reset the

system if an application hangs. Close pins

2-3 to generate a non-maskable interrupt

signal for the application that hangs. See

the table on the right for jumper settings.

Watch Dog must also be enabled in the

BIOS.

Troubleshooting

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed

all of the procedures below and still need assistance, refer to the ‘Technical Sup-

port Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this

chapter.

Note: Always disconnect the power cord before adding, changing or install-

ing any hardware components.

Before Power On

1. Make sure that there are no short circuits between the motherboard and chas-

sis.

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

keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis

speaker and the power LED to the motherboard. (Check all jumper settings

as well.)

No Power

1. Make sure that there are no short circuits between the motherboard and chas-

sis..

2. Make sure 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 make sure that it still

supplies ~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 B for

details on beep codes.

3. Remove all memory modules and turn on the system. (If the alarm is on, check

the specs of the memory, reset the memory or try a different one.)

3-1

X7DWA-N User's Manual

Losing the System’s Setup Confi guration

1. Make 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 sup-

plies ~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.

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. Check if different speeds of DIMMs have been installed, and make sure that

the BIOS setup is confi gured for the fastest speed of RAM used. It is recom-

mended to use the same RAM speed for all DIMMs in the system.

3. Make sure you are using the correct type of DDR2 FBD (Fully Buffered) ECC

800/667/533 SDRAM (*recommended by the manufacturer). Also make

sure that the type of memory used is supported by the CPU installed on the

motherboard. Refer to Page 2-6 for more information.

4. Check for bad DIMM modules or slots by swapping a single module between

four slots and noting the results.

5. Make sure all memory modules are fully seated in their slots. As an interleaved

memory scheme is used, you must install two modules at a time, beginning

with 1A, then 1B, and so on (see Page 2-6).

6. Check the position of the 115V/230V switch on the power supply.

3-2 Technical Support Procedures

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

that as a motherboard manufacturer, Super Micro 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.

3-2

Chapter 3: Troubleshooting

2. BIOS upgrades can be downloaded from our web site at (http://www.supermicro.

com/support/bios/

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

boot block code.

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

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 [email protected] or by fax at: [phone],

option 2.

3-3 Frequently Asked Questions

Question: What are the various types of memory that my motherboard can

support?

Answer: The X7DWA-N has eight 240-pin DIMM slots that support DDR2 FBD

ECC 800/667/533 SDRAM modules. It is strongly recommended that you do not

mix memory modules of different speeds and sizes.

Question: How do I update my BIOS?

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

encing no problems with your system. Updated BIOS fi les are located on our web

site at

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 BIOS before

downloading. Select your motherboard model and download the BIOS fi le to your

computer. Unzip the BIOS fi les onto a bootable fl oppy and reboot your system.

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DWA-N. The

Phoenix ROM BIOS is stored in a fl ash chip and can be easily upgraded using a

fl o p p y d i s k - b a s e d p r o g r a m .

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. Please refer to the Manual

Download area of the Supermicro web site <http://www.supermicro.com> for any

changes to the BIOS that may not be 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 Phoenix BIOS stores the system parameters,

types of disk drives, video displays, etc. in the CMOS. The CMOS memory requires

very little electrical power. When the computer is turned off, a backup battery

provides power to the CMOS Logic, enabling it to retain system parameters. When

the computer is powered on, the computer is confi gured with the values stored in

the CMOS Logic by the system BIOS, which gains control at boot up.

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

the <Delete> key 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 Security and Power menus. Beginning with Section 4-3,

detailed descriptions are given for each parameter setting in the Setup utility.

Warning: Do not shut down or reset the system while updating BIOS

to prevent possible boot failure.

*If the BIOS detects errors on 2C, 2E, or 30 (base 512K RAM errors), it displays an

additional word-bitmap (xxxx) to indicate the address line or bits that have failed. For

example, “2C 0002” means address line 1 (bit one set) has failed. “2E 1020" means

data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also

sends the bitmap to the port-80 LED display. It fi rst displays the checkpoint code,

followed by a delay, the high-order byte, another delay, and then the loworder byte

of the error. It repeats this sequence continuously.

Appendix C

Intel HostRAID Setup Guidelines

After all the hardware has been installed, you must fi rst confi gure the Intel ESB2

SATA RAID before you install the Windows Operating System and other software

drivers.

Important Notes to the User:

Note 1: If you do not wish to confi gure onboard SATA RAID functions, please

go directly to Section C-2, Appendix D and Appendix E for Operating System &

Other Software Installation.

Note 2: This chapter describes RAID Confi guration Instructions for the Intel ESB2

RAID Controller designed for the Windows OS.

C-1 Introduction to Serial ATA and Parallel ATA

To confi gure the SATA RAID functions, you must fi rst use the Intel ESB2 SATA

RAID Utility program to confi gure the RAID Level that you desire before installing

the Windows XP/2000/2003 operating system and other software drivers. (The

necessary drivers are all included on the Supermicro CD that came packaged

with your motherboard.) Note: the current version of the ESB2 SATA RAID Utility

can only support Windows XP/2000/2003 Operating Systems.

Serial ATA (SATA)

Serial ATA (SATA) is a physical storage interface that 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 transfer rates up to 3.0 Gbps. Because the serial

cables used in SATA are thinner than the traditional cables used in Parallel ATA

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

In addition, the cables used in PATA are limited to a length of 40cm, while Se-

rial ATA cables can be up to one meter in length. Overall, SATA provides better

functionality than PATA.

Introduction to the Intel ESB2 Serial RAID

Located in the South Bridge of the 5400 chipset, the I/O Controller Hub (ESB2)

provides the I/O subsystem with access to the rest of the system. It supports 1-

channel UltraATA/100 Bus Master IDE controller (PATA) and six Serial ATA (SATA)

ports. The ESB2 supports the following PATA and SATA device confi gurations:

Legacy mode and Native mode.

C-1

X7DWA-N User's Manual

The Intel HostRAID Confi gurations

The following types of Intel's HostRAID confi gurations are supported:

RAID 0 (Data Striping): this function allows data to be written (copied) into parallel,

interleaved ("striped") sections of two hard drives, achieving double data-transfer

rate than using a single disk.

RAID1 (Data Mirroring): an identical data image from one drive is copied to another

drive. The second drive must be the same size or larger than the fi rst drive.

RAID 10 (Striping & Mirroring): RAID 0 and 1 schemes are combined (without

parity) to get the benefi ts of both.

RAID 5: both data and parity information are striped and mirrored across three

or more hard drives.

The Intel Matrix Storage

The Intel Matrix Storage, supported by the ESB2, allows the user to create RAID

0, RAID 1, RAID 10 and RAID 5 sets by using only six identical hard disk drives.

The Intel Matrix Storage Technology creates two partitions on each hard disk drive

to generate virtual RAID 0, RAID 1, RAID 10 and RAID 5 sets. It also allows you

the change the HDD partition size without any data being added or deleted.

Confi guring BIOS settings for SATA RAID Functions (Native Mode)

1. Press the <Del> key during system bootup to enter the BIOS Setup Utility.

Note: If it is the fi rst time powering on the system, we recommend you load the

Optimized Default Settings. If you have already done so, please skip to Step 3.

2. Use the arrow keys to select Exit Settings. Once in the Exit settings, Scroll

down to select Load Optimized Default Settings and press the <Enter> key. Select

OK to confi rm the selection. Press the <Enter> key to load the default settings

for the BIOS.

3. Use the arrow keys to select the Main Menu in BIOS.

4. Scroll down to SATA Controller Mode and press the <Enter> key to select

Enhanced.

5. Scroll down to SATA RAID Enabled and press <Enter>. Then, select En-

abled.

6. Go to Exit. Select Exit Saving Changes from the Exit menu. Press <Enter> to

save the changes and exit the BIOS.

7. Once you've exited the BIOS Utility, the system will re-boot.
