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-G/X6DHE-G motherboard. The X6DH8-G/X6DHE-G supports
single or dual Intel® NoconaTM processors at a 800 MHz front side bus.
Based upon Intel's NetBurst microarchitecture with EM64T support, 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 (800 MHz) supports Hyper-Threading Technol­ogy and is ideal for high performance workstation and server environments
with up to two processors on one system bus. Please refer to the mother­board specifications pages on our web site (http://www.supermicro.com/
Product/) for updates on supported processors. This product is intended to
be professionally installed.

Introduction

X6DH8-G/X6DHE-G 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 power­on state. See the Power Lost Control setting in the Advanced BIOS Setup
section to change this setting. The default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
X6DH8-G/X6DHE-G. 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/Software On/Off 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.

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. It can continue to monitor for overheat conditions even when the
CPU is in sleep mode. Once it detects that the CPU temperature is too high,
it will automatically turn on the thermal control fan to prevent any overheat

Chapter 1: Introduction

1-11

Introduction

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.

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.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to
20A current. This will allow the regulator to run cooler and thus make the
system more stable.

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.

1-12

Introduction

X6DH8-G/X6DHE-G User's Manual

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 the Win­dows 2000, Windows 2003, and Windows XP.

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. 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.

Chapter 1: Introduction

1-13

Introduction

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
Network Interface Card (NIC) that has WOL capability. Wake-On-LAN must
be enabled in the 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 SUPER X6DH8-G/X6DHE-G accommodates ATX 24-pin 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. Your power supply must supply 1.5A for the Ethernet
ports. The +12V, 4-pin power connector (J38) is required to ensure ad­equate power supply to the system. Additionally, you should also use the
onboard 12V 8-pin power connector (J1D1) to support Intel Xeon CPUs.
Failure to provide this extra power will result in instability of the CPU after
only a few minutes of operation. 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 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.

Introduction

X6DH8-G/X6DHE-G User's Manual

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). 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 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.

Installation

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.

2-2

X6DH8-G/X6DHE-G User's Manual

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 heatsink.

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)

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.

!

Socket lever

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.)

Pin 1

Socket lever in the
locking Position

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.

1. Do not apply any thermal grease 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.

X6DH8-G/X6DHE-G User's Manual

(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.

Figure 2-1. PGA604 Socket: Empty and with Processor Installed

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Make sure the locations 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 on Page 2-6)

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-G/X6DHE-G supports up to 16/32 GB Registered ECC DDR 333/
266 (PC2700/PC2100) memory. All motherboards were designed to support
2GB (DDR333)/4GB (DDR 266) modules in each slot, but has only been
verified for up to 1 GB modules.

DDR333 Memory Support

The X6DH8-G/X6DHE-G supports up to 4 Double-Bank or 6 Single-Bank
DDR333 memory modules.

Note: Due to memory allocation to system devices, memory remaining avail­able for operational use will be reduced when 4GB of RAM is used. The
reduction in memory availability is disproportional. (Refer to the table on
Page 2-7.)

Chapter 2: Installation

2-7

To Remove:

Use your thumbs to
gently push near the edge
of both ends of the
module. This should
release it from the slot.

2-4 I/OPorts/Control Panel Connectors

The I/O ports are color coded in conformance with the PC 99 specification.
See Figure 2-3 below for the colors and locations of the various I/O ports.

Power LED/Speaker

On the JDI header, pins 1-3 are for a
power LED and pins 4-7 are for the
speaker. See the table on the right for
speaker pin definitions. Note: The
speaker connector pins are for use with
an external speaker. If you wish to use
the onboard speaker, you should close
pins 6-7 with a jumper.

Fan Headers

The X6DH8-G/X6DHE-G has eight fan
headers (Fan1 to Fan8). (*Note: These
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 definitions. (*The
onboard fan speed is controlled by Ther­mal Management under Hardware Monitor­ing in the Advanced Setting in the BIOS.
Note: Default: Disabled, When using Ther­mal Management setting, please use all 3­pin fans or all 4-pin fans on the mother­board.)

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.

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.

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
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 that there are no short circuits 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.

3-2

X6DH8-G/X6DHE-G User's Manual

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.

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/Non ECC
DDR-333/266 (PC2700/PC2100) SDRAM (*Please refer to Page 2-5 for
the instruction on DDR 333 DIMM population and installation.)

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.

3-3

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/support/faqs/) before con­tacting Technical Support.

2. BIOS upgrades can be downloaded from our web site at

(http://www.supermicro.com/support/bios/).

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 infor-

mation 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/support/contact.cfm).

4. Distributors: For immediate assistance, please have your account number
ready when placing a call to our technical support department. We can
be reached by e-mail at [e-mail], by phone at:
[phone], option 2, or by fax at [phone].

3-3 Frequently Asked Questions

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

Answer: The X6DH8-G/X6DHE-G has eight 184-pin DIMM slots that support

registered ECC/Non ECC DDR 333/266 (PC2700/PC2100) SDRAM modules.
It is strongly recommended that you do not mix memory modules of different
speeds and sizes. (*Please refer to Page 2-5 for the instruction on DDR
333 DIMM population and installation.)

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 down­load the BIOS file to your computer. Unzip the BIOS files onto a bootable
floppy and reboot your system. Then, follow Readme.txt to continue flash­ing the BIOS.

3-4

X6DH8-G/X6DHE-G User's Manual

Question: What's on the CD that came with my motherboard?

Answer: The supplied compact disc has quite a few drivers and programs

that will greatly enhance your system. We recommend that you review the
CD and install the applications you need. Applications on the CD include
chipset drivers for Windows and security and audio drivers.

3-4 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is
required before any warranty service will be rendered. You can obtain
service by calling your vendor for a Returned Merchandise Authorization
(RMA) number. When returning to the manufacturer, the RMA number
should be prominently displayed on the outside of the shipping carton, and
mailed prepaid or hand-carried. Shipping and handling charges will be ap­plied for all orders that must be mailed when service is complete.

This warranty only covers normal consumer use and does not cover dam­ages incurred in shipping or from failure due to the alternation, misuse,
abuse or improper maintenance of products.

Chapter 4

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X6DH8-G/
X6DHE-G. 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 <http://www.supermicro.com/support/bios/> for BIOS updates.

System BIOS

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, 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 BIOS flash chip, en­abling it to retain system parameters. Each time when 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.

System CMOS checksum bad - Default configuration used

System CMOS has been corrupted or modified incorrectly, perhaps by an
application program that changes data stored in CMOS. The BIOS installed Default
Setup Values. 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.

System timer error

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 configuration 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 configuration 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.

Diskette drive A error

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 configuration error
1 continuous 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 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 first 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.

C-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 6300ESB (Hance Rapids) I/O Con­troller Hub

Located in the South Bridge of the Intel E7525 Lindenhurst Chipset, the
6300ESB (Hance Rapids) 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
6300ESB (Hance Rapids) I/O Controller Hub supports the following Parallel
ATA (PATA) and Serial (SATA) device configurations:

Appendix C

Installing Software Drivers and Windows

Operating System

After all the hardware has been installed, you must first configure the

ATA Operate Mode

You can select from the following two modes: Combined Mode and Enhanced
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 sup-

ported;
*Non-Combined Mode: Serial ATA only:with the maximum of 2 devices sup-

ported;
*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-G/X6DHE-G 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-G/X6DHE-G
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.)

C-10

X6DH8-G/X6DHE-G User's Manual

Notes:

1. Before adding a new drive to an array, back up any data contained on
the new drive. Otherwise, all data will be lost.

2. If you stop the Build or Clear process on a RAID 1 from ACU, you can
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.

5. When you are finished, press Done (as the screen shown below).

Initializing Disk Drives

If an installed disk does not appear in the disk selection list for creating a
new array, or if it appears grayed out, you may have to initialize it before
you can use it as part of an array. Drives attached to the controller must be
initialized before they can be used in an array.

Caution: Initializing a disk overwrites the partition table on the disk and
makes any data on the disk inaccessible. If the drive is used in an array,
you may not be able to use the array again. Do not initialize a disk that is
part of a boot array. To determine which disks are associated with a
particular array, please refer to Viewing Array Properties.

To initialize drives:

1. Turn on your computer and press Ctrl+A when prompted to access the
ARC utility.

2. From the ARC menu, select Array Configuration Utility (ACU) (as shown
in the screen below).

3. Select Initialize Drives (as shown in the screen below).
