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 X6DH8-G2/X6DHE-G2 motherboard. The X6DH8-G2/
X6DHE-G2 supports single or dual Intel® NoconaTM processors at a 800
MHz front side bus. Based upon Intel's NetBurst microarchitecture, the
Nocona processor supports the IA-32 software and includes features
found in the XeonTM processor such as Hyper Pipelined Technology, which
includes a multi-stage pipeline, allowing the processor to operate at much
higher core frequencies. Packaged in a 604-pin Flip Chip Micro Pin Grid
Array(FC-mPGA4) platform in a Zero Insertion Force(ZIF) socket (mPGA
604), the Nocona Processor, which supports Hyper-Threading Technology
and Intel EM64T, is ideal for high performance workstation and server
environments with up to two processors on one system bus. Please refer

Chapter 1: Introduction
1-2 Chipset Overview
Built upon the functionality and the capability of the E7520 Lindenhurst
chipset, The X6DH8-G2/X6DHE-G2 motherboard provides the performance
and feature set required for dual processor-based servers, with configuration options optimized for communications, presentation, storage, computation or database applications. The Intel E7520 Lindenhurst chipset consists
of the following components: the Lindenhurst Memory Controller Hub (MCH),
the 82801ER I/O Controller Hub 5-R (ICH5-R), and the Intel PCI-X Hub.
The E7520 Lindenhurst MCH supports single or dual Nocona processors
with Front Side Bus speeds of up to 800 MHz(*Note). Its memory controller
provides direct connection to two channels of registered DDR2- 400 with a
marched system bus address and data bandwidths of up to 6.4GB/s. The
Lindenhurst also supports the new PCI Express high speed serial I/O interface for superior I/O bandwidth. The MCH provides three configurable x8
PCI Express interfaces which may alternatively be configured as two independent x4 PCI Express interfaces. These interfaces support connection of
the MCH to a variety of other bridges that are compliant with the PCI Express Interface Specification, Rev. 1.0a. The MCH interfaces with the
82801ER I/O Controller Hub 5-R (ICH5R) via a dedicated Hub Interface supporting a peak bandwidth of 266 MB/s using a x4 base clock of 66 MHz. The
PXH provide connection between a PCI Express interface and two independent PCI bus interfaces that can be configured for standard PCI 2.3 protocol, as well as the enhanced high-frequency PCI-X protocol. The PXH can
be configured to support for 32- or 64-bit PCI devices running at 33 MHz, 66
MHz, 100 MHz, and 133 MHz.
Introduction
The ICH5R I/O Controller Hub provides legacy support similar to that of
previous ICH-family devices, but with extensions in RAID 0,1 support, Serial
ATA Technology, and an integrated ASF Controller. In addition, the ICH5R
also provides various integrated functions, including a two-channel Ultra
ATA/100 bus master IDE controller, USB 2.0 host controllers, an integrated
10/100 LAN controller, an LPC firmware hub (FWH) and Super IO interface,
a System Management Interface, a power management interface, integrated
IOxAPIC and 8259 interrupt controllers.

X6DH8-G2/X6DHE-G2 User's Manual
1-3 Special Features
Recovery from AC Power Loss
Introduction
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 poweron state. See the Power Lost Control setting in the Advanced BIOS Setup
section (Peripheral Device Configuration) to change this setting. The default setting is Always On.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X6DH8-G2/
X6DHE-G2. All have an onboard System Hardware Monitor chip that supports PC health monitoring.
Onboard Voltage Monitors for the CPU Cores, Chipset
Voltage, +3.3V, +5V, +12V and +3.3V 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 define 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-defined 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 define an overheat temperature. When this temperature 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. SDIII is used to
notify the user of certain system events. For example, if the system is
running low on virtual memory and there is insufficient hard drive space for
saving the data, you can be alerted of the potential problem.
.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible 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.
Introduction
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 configuration 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.

X6DH8-G2/X6DHE-G2 User's Manual
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to
Introduction
system and device power control. OnNow is a term for a PC that is always
on but appears to be off and responds immediately to user or other requests.
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.
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. Depressing
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 depress 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 defined as the ability of a management application to remotely power up a computer that is powered off. Remote PC setup, updates and asset tracking can occur after hours and on weekends so that
daily LAN traffic 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
1-12
Chapter 1: Introduction
Network Interface Card (NIC) that has WOL capability. Wake-On-LAN must
be enabled in BIOS. Note that Wake-On-LAN can only be used with 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 X6DH8-G2/X6DHE-G2 can only accommodates 24-pin ATX power supplies. Although most power supplies generally meet the specifications required by the CPU, some are inadequate. You should use one that will
supply at least 400W of power connector. In addition, the 12V 4-pin power
supply (J32) - is also required to ensure adequate power supply to the
system. Also your power supply must supply 1.5A for the Ethernet ports.
NOTE: The + 12V 8-pin Aux. Power Connector (J1D1) is also required
to support Intel Xeon CPUs. Failure to provide this extra power will
result in CPU PWR Failure. See Section 2-5 for details on connecting the power supply.
Introduction
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 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 filter
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 floppy 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 floppy 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), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
1-13
X6DH8-G2/X6DHE-G2 User's Manual
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
Introduction
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 Configuration 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.
The IRQs, DMAs and I/O space resources of the Super I/O can flexibly
adjust to meet ISA PnP requirements, which support ACPI and APM (Advanced Power Management).

2-1 Static-Sensitive Devices
Electric-Static-Discharge (ESD) can damage electronic components. To prevent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient 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. Do not install the
onboard upside down battery 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.
2-1
X6DH8-G2/X6DHE-G2 User's Manual
2-2 Nocona Processor and Heatsink Installation
When handling the processor package, avoid placing direct
pressure on the label area of the fan. Also, do not place the
motherboard on a conductive surface, which can damage the
!
BIOS battery and prevent the system from booting up.
IMPORTANT: 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 (CEK) heat sink. To adequately support the weight of CPU heat
sinks, please install the X6DH8-G2/X6DHE-G2 in a chassis that is compliant
with the SSI EEB 3.5 Specification.
CPU Installation
1. Lift the lever on the CPU socket:
lift the lever completely as shown
on the picture on the right;
otherwise, you will damage the
CPU socket when power is
applied. (Install CPU1 first.)
2. Insert the CPU in the socket,
making sure that pin 1 of the CPU
aligns with pin 1 of the socket
(both corners are marked with a
triangle). When using only one
CPU, install it into CPU socket #1
(socket #2 is automatically disabled
if only one CPU is used).
3. Press the lever down until
you hear the *click* so you
can be sure that the CPU is
securely installed in the CPU
socket.

CEK Heatsink Installation
IMPORTANT: Due to the weight of the CEK
Passive Heatsink (which weights about 1KG),
you need to have Heatsink Mounting plate installed on the chassis to prevent damage to
the CPU and the motherboard)
Chapter 2: Installation
1. Do not apply any thermal compound
to the heatsink or the CPU die-the
required amount has already been
applied.
2. Place the heatsink on top of the
CPU so that the four mounting holes
are aligned with those on the retention
mechanism.
3. Screw in two diagonal screws (ie
the #1 and the #2 screws) until just
snug (-do not fully tighten the screws
to avoid possible damage to the CPU.)
4. Finish the installation by fully
tightening all four screws.

To Un-install the Heatsink
(Caution! We do not recommend that the
CPU or the heatsink be removed. However, if you do need to un-install the
heatsink, please follow the instructions
below to uninstall the heatsink to prevent
damage done to the CPU or the CPU
socket. )
1. Unscrew and remove the heatsink
screws from the motherboard in the
sequence as show in the picture on
the right.
2. Hold the heatsink as show in the
picture on the right and gently wriggle
the heatsink to loosen it from the CPU.
(Do not use excessive force when
wriggling the heatsink!!)
3. Once the CPU is loosened, remove
the heatsink from the CPU socket.
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 fit different types of
chassis. Make sure the location of all the mounting holes for both the
motherboard and the chassis match. Although a chassis may have both
plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure the metal
standoffs click in or are screwed in tightly. Then use a screwdriver to
secure the motherboard onto the motherboard tray.

2-3 Installing DIMMs
Note: Check the Supermicro web site for recommended memory modules:
http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm
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. The memory scheme is interleaved so you must install two
modules at a time, beginning with Bank 1, then Bank 2, and so on.
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 X6DH8-G2/X6DHE-G2 supports up to 16 GB of Registered ECC DDR2400 (PC3200) memory. All motherboards were designed to support 2 GB
modules in each slot, but has only been verified for up to 1 GB modules.

Fan Headers
The X6DH8-G2/X6DHE-G2 has
eight fan headers (Fan1 to Fan8).
Fan1-Fan4 are 3-pin fans, and
Fan5-Fan8 are 4-pin fans. (* Note:
Fan5-Fan8 are 4-pin fan headers;
however, Pins 1-3 of these fan
headers are backward compatible
with the traditional 3-pin fans.)
See the table on the right for pin
definitions. (*The onboard fan
speed is controlled by Thermal
Management via BIOS. To activate
Fan Speed Control, please refer to
"Hardware Monitoring" in the Advanced Setting.)

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 identified
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 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. Do
not use the PW_ON connector to clear CMOS.
Watch Dog
JWD controls Watch Dog, a system
monitor that takes action when a
software application freezes the
system. Pins 1-2 will have WD reset the system if a program
freezes. Pins 2-3 will generate a
non-maskable interrupt for the program that has frozen (requires software implementation). Watch Dog
must also be enabled in BIOS.

2-8 Parallel Port, Floppy/Hard Disk Drive and SCSI
Connections
Note the following when connecting the floppy and hard disk drive cables:
• The floppy disk drive cable has seven twisted wires.
• A red mark on a wire typically designates the location of pin 1.
• A single floppy disk drive ribbon cable has 34 wires and two connectors to
provide for two floppy disk drives. The connector with twisted wires always
connects to drive A, and the connector that does not have twisted wires
always connects to drive B.
Parallel (Printer) Port
Connector
The parallel (printer) port is located on J23. See the table on the

Chapter 3
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 possible 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
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.
3-1
X6DH8-G2/X6DHE-G2 User's Manual
NOTE
If you are a system integrator, VAR or OEM, a POST diagnos-
tics 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 configured 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 you are using the correct type of Registered ECC DDR2-400
(PC3200) SDRAM (*recommended by the manufacturer.)
4. Check for bad DIMM modules or slots by swapping a single module between two 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.
Losing the System’s Setup Configuration
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 ~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fix the Setup Configuration problem, contact
your vendor for repairs.
3-2 Technical Support Procedures
Before contacting Technical Support, please take the following steps. Also,
note that as a motherboard manufacturer, Super Micro does not sell directly
to end-users, so it is best to first check with your distributor or reseller for
troubleshooting services. They should know of any possible problem(s)
with the specific system configuration that was sold to you.
3-2
Chapter 3: Troubleshooting
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/TECHSUPPORT/techsupport.htm)
before contacting Technical Support.
2. BIOS upgrades can be downloaded from our web site at
http://www.supermicro.com/techsupport/download.htm.
Note: Not all BIOS can be flashed depending on the modifications
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 first boots up)
•System configuration
An example of a Technical Support form is on our web site at
http://www.supermicro.com/techsupport/contact_support.htm.
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 support@supermicro.com or by fax at:
(408) 503-8000, option 2.
3-3 Frequently Asked Questions
Question: What are the various types of memory that my motherboard can support?
Answer: The X6DH8-G2/X6DHE-G2 has eight 240-pin DIMM slots that sup-
port registered ECC DDR2-400 (PC3200) 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
experiencing no problems with your system. Updated BIOS files are located
on our web site at http://www.supermicro.com. Please check our BIOS
warning message and the info 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 down-

4-1 Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the X6DH8-G2/
X6DHE-G2. The Phoenix ROM BIOS is stored in a flash chip and can be
easily upgraded using a floppy 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 BIOS that may not be
reflected 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 flash chip stores the
system parameters, such type 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 BIOS flash
chip, enabling it to retain system parameters. Each time the computer is
powered-on the computer is configured with the values stored in the BIOS
ROM by the system BIOS, which gains control at boot-up.
How To Change the Configuration 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.

* If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), it displays an additional
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 first displays the checkpoint code, followed by
a delay, the high-order byte, another delay, and then the loworder byte of the error.

Installing Software Drivers and Windows
Operating System
After all the hardware has been installed, you must first configure the
Adaptec Embedded Serial ATA RAID Driver before you install the Windows
operating system. The necessary drivers are all included on the Supermicro
bootable CDs that came packaged with your motherboard. (*The following
section provides information on Adaptec's SATA RAID Driver based on the
Intel ICH5R Controller. For detailed information on Adaptec's SCSI SATA
HostRAID Utility, please refer to the CDs included in the shipping
package)
B-1 Introduction to the Adaptec Embedded Serial ATA
RAID Controller Driver
Serial ATA (SATA)
Serial ATA(SATA) is a physical storage interface. It uses a single cable with
a minimum of four wires to create a point-to-point connection between
devices. It is a serial link which supports SATA Transfer rates from
150MBps. Because the serial cables used in SATA are thinner than the
traditional cables used in Parallel ATA(PATA), SATA systems have better
airflow and can be installed in smaller chassis than Parallel ATA. In addition,
the cables used in PATA can only extend to 40cm long, while Serial ATA
cables can extend up to one meter. Overall, Serial ATA provides better
functionality than Parallel ATA.
Introduction to the Intel ICH5R I/O Controller Hub
Located in the South Bridge of the Intel E7520 (Lindenhurst)Chipset, the
ICH5 R I/O Controller Hub provides the I/O subsystem with access to the rest
of the system. It supports 2-channel Ultra ATA/100 Bus Master IDE controller
(PATA) and two Serial ATA (SATA) Host Controllers, which support up to two
Serial ATA ports and up to two RAID drives. The ICH5R I/O Controller Hub
supports the following Parallel ATA (PATA) and Serial (SATA) device configurations:
B-1
X6DH8-G2/X6DHE-G2 User's Manual
ATA Operate Mode
You can select from the following two modes: Combined Mode and En-
hanced Mode.
Combined Mode:
In this mode, system BIOS assigns the traditional IRQ 14 and IRQ 15 for the
use of HDD. Up to 4 ATA devices are supported by this mode.
Within the Combined Mode, the following three modes are supported:
*Non-Combined Mode: Parallel ATA only:with the maximum of 4 devices
supported;
*Non-Combined Mode: Serial ATA only:with the maximum of 2 devices
supported;
*Combined Mode: SATA devices and PATA: with the support of 2 devices
each (total: 4 devices maximum). (For IDE/SATA configurations, please refer
to the table below.)
Primary Master(=PM) Yes Yes No No No No
Primary Slave(=PS) Yes No Yes No No No
Secondary Master(=SM) Yes No No Yes No No
Secondary Slave(=SS) Yes No No No Yes No
SATA Port0 No SM SM PM PM PM
SATA Port1 No SS SS PS PS PS
*Note: (No=Not Present, Yes=Present) Also, if Logical Primary is
selected, the IDE channels are no longer available.
Enhanced Mode:
In this mode, system BIOS will automatically search for all available IRQs for
the use of HDD. For newer Operating Systems that support the Enhanced
Mode, such as Windows XP, Windows 2000, and Windows 2003, you can
set SATA and PATA to the Enhanced Mode. (*The newer Operating
Systems can accommodate both Enhanced Mode and Combined Mode and
support up to 6 ATA devices.)
(*Please refer to the "Advanced Chipset Control" under the "Advanced" Setup
in the BIOS for the selection of Combined Mode or Enhanced Mode,).

The Adaptec Embedded Serial ATA with HostRAID Controller Driver
Adaptec's Embedded Serial ATA RAID with HostRAID controller adds RAID
functionality to the Serial ATA I/O controller by supporting RAID 0
(Striping) or RAID 1 (Mirroring) to enhance the industry's pioneer PCI-to-e
host controller products. RAID striping (RAID 0) can greatly improve hard
disk I/O performance because of its capability in striping data across
multiple drives. RAID mirroring (RAID 1) allows the data to be simultaneously written to two drives, so critical data is always available even if
a single hard disk fails. Due to the built-in functionality, the X6DH8-G2/
X6DHE-G2 is specially designed to keep pace with the increasing
performance demands of computer systems by improving disk I/O
throughput and providing data accessibility regardless of a single disk
failure. By incorporating the Adaptec Embedded Serial ATA into the
motherboard design, Supermicro's X6DH8-G2/X6DHE-G2 offers the user
with the benefits of SATARAID without the high costs associated with
hardware RAID applications.
(*Note: For Adaptec's RAID Driver Installation Instructions, please refer to
the Adaptec RAID Controller User's Guide: "Emb_SA_RAID_UG.pdf" in the
CD that came with this motherboard. You can also download a copy of
Adaptec's User's Guide from our web site at www.supermicro.com.)

restart it by pressing Ctrl+R.
3. A RAID 1 created using the Quick Init option may return some data miscompares if you later run a consistency check. This is normal and is not
a cause for concern.
4. The ACU allows you to use drives of different sizes in a
RAID . However, during a build operation, only the smaller drive can be
selected as the source or first drive.
5. When migrating from single volume to RAID 0, migrating from a larger
drive to a smaller drive is allowed. However, the destination drive must
be at least half the capacity of the source drive.
6. Adaptec does not recommend that you migrate or build an array on
Windows dynamic disks (volumes), as it will result in data loss.
Warning: Do not interrupt the creation of a RAID 0 using the Migrate
option. If you do, you will not be able to restart, or to recover the data
that was on the source drive.
