Preface

About This Manual

This manual is written for system integrators, PC technicians and

knowledgeable PC users. It provides information for the installation and use of the

X7DB8/X7DBE motherboard. The X7DB8/X7DBE supports dual

Intel Xeon 64-bit dual core processors at a front side bus speed of 1333/1066/667

MHz. With dual Xeon 64-bit dual core processors, the 5000P (Blackford) chipset,

and eight DDR2 FBD 667/533 memory modules built-in, the X7DB8/X7DBE offers

substantial functionality and performance enhancements to the motherboards based

on the dual core NetBurst microarchitecture while remaining compatible with the

32-bit based software. Key features include Intel's Hyper-Threading Technology,

Virtualization Technology, Hyper Pipelined Technology, Execution Trace Cache,

Thermal Monitor 1/2 (TM1/TM2), Enhanced Intel SpeedStep technology, Advanced

Dynamic Execution, Advanced Transfer Cache, Streaming SIMD Extensions 3

(SSE3) and Extended Memory 64 Technology (EM64T). These features allow the

motherboard to operate at much higher speeds with better power management in

much safer environments than the traditional motherboards. The X7DB8/X7DBE

is ideal for high performance dual processor (DP) enterprise server/workstation

environments. This product is intended to be professionally installed.

Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the 5000P (Blackford) chipset, the

X7DB8/X7DBE motherboard provides the performance and feature set required

for dual processor-based servers with confi guration options optimized for commu-

nications, presentation, storage, computation or database applications. The 5000P

(Blackford) chipset supports single or dual Xeon 64-bit dual core processor(s) with

front side bus speeds of up to 1.333 GHz. The chipset consists of the 5000P

(Blackford) Memory Controller Hub (MCH), the Enterprise South Bridge 2 (ESB2),

and the I/O subsystem (PXH).

The 5000P (Blackford) MCH chipset is designed for symmetric multiprocessing

across two independent front side bus interfaces. Each front side bus uses a 64-

bit wide, 1333 MHz data bus that transfers data at 10.7 GB/sec. In addition, the

5000P (Blackford) chipset offers a wide range of RAS features, including memory

interface ECC, x4/x8 Single Device Data Correction, CRC, parity protection, memory

mirroring and memory sparing.

The Xeon Dual Core Processor Features

Designed to be used with conjunction of the 5000P (Blackford) chipset, the Xeon

dual core Processor provides a feature set as follows:

The Xeon Dual Core Processors

*L1 Cache Size: Instruction Cache (32KB/16KB), Data Cache (32KB/24KB)

*L2 Cache Size: 4MB/2MB (per core)

*Data Bus Transfer Rate: 8.5 GB/s

*Package: FC-LGA6/FC-LGA4, 771 Lands

X7DB8/X7DBE 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 (Peripheral Device Confi guration) to

change this setting.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DB8/X7DBE. All

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

ing.

Onboard Voltage Monitors for CPUCore, +3.3V, +5V, +12V, −12V
and +5V standby

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

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

the screen. Users can adjust the voltage thresholds to defi ne the sensitivity

of the voltage monitor.

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 turn

on the thermal control fan whenever the CPU temperature exceeds a user-defi ned

threshold. The overheat circuitry runs independently from the CPU. Once it detects

that the CPU temperature is too high, it will automatically turn on the thermal fan

control to prevent any overheat damage to the CPU. The onboard chassis thermal

circuitry can monitor the overall system temperature and alert users when the chas-

sis temperature is too high.

1-10

Chapter 1: Introduction

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It continues 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 and Control

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. When this tem-

perature is exceeded, both the overheat fan and the warning LED are triggered.

System Resource Alert

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

vironment or used with Supero Doctor II in Linux. Supero Doctor is used to notify

the user of certain system events. For example, you can also confi gure Supero

Doctor to provide you with warnings when the system temperature, CPU tempera-

tures, voltages and fan speeds go 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

way 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

provides a generic system event mechanism for Plug and Play and an operating

system-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 both Windows 2000 and Windows NT 5.0.

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.

1-11

X7DB8/X7DBE User's Manual

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 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. This option can be set in the Power section of

the BIOS Setup routine.

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 X7DB8/X7DBE can only accommodates 24-pin ATX power supplies. Although

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

are inadequate. In addition, the 12V 4-pin power supply - is also required to ensure

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

for the Ethernet ports.

1-12

Chapter 1: Introduction

NOTE: The + 12V 8-pin Aux. Power Connector is also required to support

Intel 64-bit CPUs. Failure to provide this extra power will result in CPU PWR

Failure. See Section 2-5 for details on connecting the power supply.

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

power supply Specifi cation 2.02 or above. It must also be SSI compliant (info at

http://www.ssiforum.org/). Additionally, 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

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 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

system. 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

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 onboard CMOS battery as specifi ed by the manu-

facturer. Do not install the onboard battery upside down to avoid possible explo-

sion.

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.

When handling the processor package, avoid placing

direct pressure on the label area of the fan.

(*Notes: 1. Always connect the power cord last and always remove it before adding,

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

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

2. Intel's boxed Xeon CPU package contains the CPU fan and heatsink assembly.

If you buy a CPU separately, make sure that you use only Intel-certifi ed multi-di-

rectional heatsink and fan.

3. The Intel Xeon LGA 771 heatsink and fan comes with a push-pin design and no

tool is needed for installation.

4. Make sure to install the motherboard into the chassis before you install the CPU

heatsink and fan.)

5. When purchasing an LGA 771 CPU or when receiving a motherboard with an LGA

771 CPU pre-installed, make sure that the CPU plastic cap is in place and none of

the CPU pins are bent; otherwise, contact the retailer immediately.

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fi t different types of chas-

sis. 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

precautionary measures to prevent damage done to these components when you

install the motherboard to the chassis.)

X7DB8/X7DBE User's Manual

2-3 Installing DIMMs

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 DIMM

#1A. The memory scheme is interleaved so you must install four modules at

a time, beginning with DIMM #1A, then DIMM #2A and so on. *For optimal

performance, please install four modules at a time up to 8 modules. (*See

the Memory Installation Table Below.)

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 X7DB8/X7DBE supports up to 16 GB (32 GB) fully buffered (FBD) ECC DDR2

533/667 in 8 DIMMs. Populating DIMM modules with pairs of memory modules

of the same size and same type will result in Interleaving Memory which will

increase memory performance.

*Note: Due to OS limitations, some operating systems may not show more than 4

GB of memory.

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 connec-

tors meet the SSI EPS 12V specifi ca-

tion. The 4-pin 12V PWR supply is

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.

Processor Power Connector

In addition to the Primary ATX power

connector (above), the 12V 8-pin CPU

PWR connector at JPW3 must also

be connected to your power supply.

See the table on the right for pin

defi nitions.

X7DB8/X7DBE User's Manual

Fan Headers

The X7DB8/X7DBE has eight chassis/system

fan headers (Fan1 to Fan8) and two CPU Fans

(Fans 7/8). (*Note: all these fans are 4-pin fans.

However, Pins 1-3 of the fan headers are

backward compatible with the traditional 3-pin

fans.) See the table on the right for pin defi ni-

tions. (*The onboard fan speeds are controlled

by Thermal Management via BIOS Hardware
Monitor in the Advanced Setting. Note: Default:

Disabled, When using Thermal Management

setting, please use all 3-pin fans or all 4-pin

fans on the motherboard.)

Keylock

The keyboard lock connection is designated

JK1. Utilizing this header allows you to inhibit

any actions made on the keyboard, effectively

"locking" it.

Compact Flash Card PWR
Connector

A Compact Flash Card Power

Connector is located at JWF1. For

the Compact Flash Card or the Compact

Flash Jumper (JCF1) to work properly,

you will need to connect the Compact

Flash Card power cable to JWF1 fi rst.

Refer to the board layout below for

the location.

SGPIO Headers

There are two SGPIO (Serial General

Purpose Input/Output) headers (J29,

J30) located on the motherboard. These

headers support serial link interfaces for

the onboard SATA and SAS connectors.

See the table on the right for pin

defi nitions. Refer to the board layout

below for the location.

2-6 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.

Chapter 2: Installation

CMOS Clear

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

pads to prevent the 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 clear-

ing 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

JWD controls the Watch Dog function. Watch

Dog is a system monitor that can reboot the

system when a software application is “hung

up”. Pins 1-2 will cause WD to reset the sys-

tem if an application is hung up. Pins 2-3 will

generate a non-maskable interrupt signal for

the application that is hung up. See the table

on the right for jumper settings. Watch Dog

must also be enabled in BIOS.

Note: When enabled, the user needs to write

their own application software in order to dis-

able the Watch Dog Timer.

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 Support

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

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

any hardware components.

Before Power On

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

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.)

5. Use only the correct type of CMOS onboard battery as recommended by the

Manufacturer. Do not install the onboard battery upside down to avoid pos-

sible explosion.

No Power

1. Make sure no short circuits exist 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 the Appendix

for details on beep codes.

Losing the System’s Setup Confi guration

1. Ensure 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

3-1

X7DB8/X7DBE User's Manual

~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. Determine if different speeds of DIMMs have been installed and verify 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 Fully Buffered (FBD) ECC

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

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 Bank 1, then Bank 2, and so on (see Section 2-3).

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

3-2 Technical Support Procedures

Chapter 4: BIOS

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DB8/X7DBE.

The Phoenix ROM BIOS is stored in a fl ash 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. 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 pro-

vides power to the CMOS Logic, enabling it to retain system parameters. Each time

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. (See below.)

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 de-

scriptions 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.

Appendix B: BIOS POST Codes

Appendix B

BIOS POST Codes

This section lists the POST (Power On Self Test) codes for the PhoenixBIOS. POST

codes are divided into two categories: recoverable and terminal.

Recoverable POST Errors

When a recoverable type of error occurs during POST, the BIOS will display an

POST code that describes the problem. BIOS may also issue one of the follow-

ing beep codes:

1 long and two short beeps - video confi guration error

1 repetitive long beep - no memory detected

Terminal POST Errors

If a terminal type of error occurs, BIOS will shut down the system. Before doing

so, BIOS will write the error to port 80h, attempt to initialize video and write the

error in the top left corner of the screen. The following is a list of codes that may

be written to port 80h.

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

tional word-bitmap (xxxx) indicating the address line or bits that 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

The Intel HostRAID Setup Guidelines

After all the hardware has been installed, you must fi rst confi gure Intel's 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-3 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 that 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 than

Parallel ATA. In addition, the cables used in PATA are limited to a length of 40cm,

while Serial 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 5000P (Blackford) chipset, the I/O Controller

Hub (ESB2) provides the I/O subsystem with access to the rest of the system. It

supports an 1-channel UltraATA/100 Bus Master IDE controller (PATA) and six Se-

rial ATA (SATA) ports. The ESB2 supports the following PATA and SATA device

confi gurations: Legacy mode and Native mode.

C-1

X7DB8/X7DBE User's Manual

The Intel HostRAID Confi gurations

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

RAID 0 (Data Striping): this writes data in parallel, interleaved ("striped") sections

of two hard drives. Data transfer rate is doubled over 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

information) 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 and generate a virtual RAID 0, RAID 1, RAID 10 and RAID 5 sets. It also

allows you the change the HDD partition size without any data.

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 the "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" section 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 the

<Enter> key to save the changes and exit the BIOS.

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