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 com-
munications, presentation, storage, computation or database applications. The
5000P (Blackford) chipset supports single or dual Xeon 64-bit quad-core/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 64­bit 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 Quad-core/dual-core Processor Features

Designed to be used with conjunction of the 5000P (Blackford) chipset, the Xeon
quad-core/dual-core Processor provides a feature set as follows:

The Xeon Quad-core/dual-core Processors

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

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 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 monitor­ing.

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 chas­sis 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 envi­ronment 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 temperatures,
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 ca-
tion 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, Windows XP and
Windows 2003 Servers.

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 accommodate 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 64­bit 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 generator ,
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 manage­ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

Installation

2-1 Static-Sensitive Devices

Electro-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 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 Processor and Heatsink Installation

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.

6. Refer to the MB Features Section for more details on CPU support.

Chapter 2: Installation

4. Clean the surface of the CPU and the
heatsink to get rid of the old thermal grease.
Reapply the proper amount of thermal grease
on the surface before you re-install the CPU
and the heatsink.

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 two modules at a
time, beginning with DIMM #1A, then DIMM #2A and so on. (*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 Interleaved Memory which will

increase memory performance.

Note 1: Due to OS limitations, some operating systems may not show more than

4 GB of memory.

you need to use the memory modules of the same speed and of the same type on a
motherboard. iii. Interleaved memory is supported when pairs of DIMM modules are
installed. To optimize memory performance, please install pairs of DIMMs in both
Branch 0 and Branch 1. iv. For memory to work properly, you need to follow the
restrictions listed above. )

Note 2: Due to memory allocation to system devices, memory remaining available
for operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. (Refer to the following Memory Availability

ATX Power Connector

There are a 24-pin main power sup­ply connector(JPW1) and an 8-pin
CPU PWR connector (JPW3) on the
motherboard. These power connec­tors 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.

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.)

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 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 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 sy stem moni tor that c an reb oot
the system w hen a soft ware applicati on hangs
Close Pins 1-2 to reset the system if an applica­tion hangs. Close Pins 2-3 to generate a non­maskable 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 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 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 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 the

chassis.

2. Make sure that all jumpers are set to their default positions.

3. Check to make sure 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 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 the Appendix

for details on beep codes.

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.

3-1

X7DB8/X7DBE User's Manual

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.

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 that the DIMM modules are properly and fully installed.

2. Check 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 recommended to
use the same RAM speed for all DIMMs in the system.

3. Make sure that 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 that 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

Before contacting Technical Support, please take the following steps. Also, note
that as a motherboard manufacturer, Supermicro does not sell directly to end-us­ers, 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.

3-3 Frequently Asked Questions

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

support?

Answer: The X7DB8/X7DBE has eight 240-pin DIMM slots that support DDR2

FDB ECC 533/667 SDRAM modules. It is strongly recommended that you do not
mix memory modules of different speeds and sizes. (See Chapter 2 for detailed
Information.)

Question: How do I update my BIOS?

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

experiencing any problems with your system. Updated BIOS fi les are located on
our web site at http://www.supermicro.com/support/bios/. Please check our BIOS
warning message and the information on how to update your BIOS on our web
site. Select your motherboard model and download the BIOS fi le to your computer.
Also, check the current BIOS revision and make sure that it is newer than your
BIOS before downloading. You can choose from the zip fi le and the .exe fi le. If
you choose the zip BIOS fi le, please unzip the BIOS fi le onto a bootable device or
a USB pen. Run the batch fi le using the format fl ash.bat fi lename.rom from your
bootable device or USB pen to fl ash the BIOS. Then, your system will automati-
cally reboot. If you choose the .exe fi le, please run the .exe fi le under Windows to
create the BIOS fl ash fl oppy disk. Insert the fl oppy disk into the system you wish
to fl ash the BIOS. Then, bootup the system to the fl oppy disk. The BIOS utility will
automatically fl ash the BIOS without any prompts. Please note that this process
may take a few minutes to complete. Do not be concerned if the screen is paused
for a few minutes.

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 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. (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 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.

System CMOS has been corrupted or modifi ed incorrectly, perhaps by an application
program that changes data stored in CMOS. The BIOS installed Default Setup V alues.
If you do not want these values, enter Setup and enter your own values. If the error
persists, check the system battery or contact your dealer.

The timer test failed. Requires repair of system board.

Real time clock error
Real-Time Clock fails BIOS hardware test. May require board repair.

Check date and time settings

BIOS found date or time out of range and reset the Real-Time Clock. May require
setting legal date (1991-2099).

Previous boot incomplete - Default confi guration used

Previous POST did not complete successfully. POST loads default values and offers
to run Setup. If the failure was caused by incorrect values and they are not corrected,
the next boot will likely fail. On systems with control of wait states, improper Setup
settings can also terminate POST and cause this error on the next boot. Run Setup
and verify that the waitstate confi guration is correct. This error is cleared the next
time the system is booted.

Memory Size found by POST differed from CMOS

Memory size found by POST differed from CMOS.

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 follow­ing beep codes:

1 long and two short beeps - video confi guration error
1 repetitive long beep - no memory detected
1 continuous beep (with front panel OH LED on) - system overheat

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 errors on 2C, 2E, or 30 (base 512K RAM error), it displays an
additional word-bitmap (xxxx) indicating 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

Appendix C

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-2 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 Se­rial 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 "En­abled."

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.

8. During the system boot-up, press the <Ctrl> and <I> keys simultaneously to run
the Intel RAID Confi guration Utility when prompted by the following message: Press
<Ctrl> <I> for the Intel RAID Confi guration Utility.

(Note: The Intel RAID Confi guration Utility is only available for systems with two
or more drives installed. The Intel RAID Utility screen will not display in systems
with one drive installed.)
