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 press the power switch to turn it back
on) or for it to automatically return to a power- on state. See 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 X8DTG-DF. All have
an onboard System Hardware Monitor chip that supports PC health monitoring.
An onboard voltage monitor will scan these onboard voltages continuously: CPU1
VCore, CPU2 VCore, +5Vin, 12Vcc (V), V P1 DIMM, V P2 DIMM, +3.3Vcc (V),
and Battery Voltage. 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.

To avoid possible system overheating, please be sure to provide adequate
airfl ow to your system.

System Resource Alert

This feature is available when used with Supero D octor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notif y the user of cer tain system events. For example, you can also confi gure

1-10

Chapter 1: Introduction

Supero Doctor to provide you with warnings when the system temperature, CPU
temperat ures, volt ages a nd fan spe eds go beyon d 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.

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 Windows XP/Windows 2003/Windows 2008/
Windows Vista Operating Systems.

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.

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.

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 (For more

1-11

X8DTG-DF User's Manual

information, please refer to the web site 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.

Note 1. For the proprietary 20-pin main power connector (JPW1) and the
8-pin PCI-Exp. Graphic card power connectors (JPW2/JPW3) to work prop­erly , please customize your power cables based on the SMC PWR Connec­tor Pin-Out Defi nitions listed in the tables on Page 2-20 in Chapter 2.

2. For the PCI-Exp. Graphic cards to work properly, please connect the
PCI-E graphic card power connectors (JPW2/JPW3) to the power sup­ply.

1-7 Overview of the Winbond WPCM450 Controller

The Winbond WPCM450, a Baseboard Management Controller (BMC), supports
the 2D/VGA-compatible Graphics Core with the PCI interface, Virtual Media, and
Keyboard/Video/Mouse (KVM) Redirection modules.

The WPCM450 BMC interfaces with the host system via a PCI interface to com­municate with the graphics core. It supports USB 2.0 and 1.1 for remote keyboard/
mouse/virtual media emulation. It also provides LPC interface to control Super IO
functions. The WPCM450 is connected to the network via an external Ethernet
PHY module.

The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, Platform Environment Control Interface (PECI) buses.

2-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. T o 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

•

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

Unpacking

The motherboard is shipped in antist atic packag i n g t o avo id static da m a ge. When
unpacking the board, make sure the person handling it is static protected.

X8DTG-DF User's Manual

2-2 Motherboard Installation

All motherboards have standard mounting holes to fi t different types of chassis.
Make sure that the locations of all the mounting holes for both motherboard and
chassis match. 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 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 to these components when installing
the motherboard to the chassis.

Fan Headers

The X8DTG-DF has eight chassis/system fan
headers (Fan1 to Fan8) on the motherboard.
All these 4-pin fans headers are backward
compatible with the traditional 3-pin fans. 3-pin
fans do not support fan speed control. How­ever, fan speed control is available for 4-pin
fans. The fan speeds are controlled by Thermal
Management via Hardware Monitoring in the
Advanced Setting in the BIOS. (The Default
setting is Disabled.) See the table on the right

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 th e jumpe r is of f the pi ns.

X8DTG-DF User's Manual

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 (JWD1) is a system monitor that
reboots the system when a software applica­tion hangs. Close Pins 1-2 to reset the system
if an application hangs. Close Pins 2-3 to
generate a non-maskable interrupt signal for
the application that hangs. See the table on
the right for jumper settings. Watch Dog must
also be enabled in the BIOS.

J_UID_OW (-Overwriting)

When the jumper J_UID_OW is set to Off (de­fault), the Red LED (Overheat/Fan Fail/PWR
Fail/UID LED) located on Pin 8 of the Front
Control Panel (JF1) will take precedence over
the Blue UID_LED located on Pin 7 of JF1. In
this case, when the Red LED is on, the Blue
LED will be turned off. When the RED LED
is off, the Blue UID_LED can be on or off. In
other words, the Red LED signal overwrites the
Blue UID_LED signal if J_UID-OW is set to off.
When the jumper J_UID_OW is On, the Red
LED (OH/Fan Fail/PWR Fail/UID LED) and the
Blue_UID_LED work independently. The Red
LED will have no effects on the Blue LED. See
the table on the right for jumper settings.

Chapter 4: AMI BIOS

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DTG-DF. The AMI
ROM BIOS is stored in a Flash EEPROM and can be easily updated. This chapter
describes the basic navigation of the AMI BIOS Setup Utility setup screens.

Starting BIOS Setup Utility

To enter the AMI BIOS Setup Utility screens, press the <Delete> key while the
system is booting up.

Note: In most cases, the <Delete> key is used to invoke the AMI BIOS
setup screen. There are a few cases when other keys are used, such as
<F1>, <F2>, etc.

Each main BIOS menu option is described in this manual. The Main BIOS setup
menu screen has two main frames. The left frame displays all the options that can
be confi gured. Grayed-out options cannot be confi gured. Options in blue can be con-
fi gured by the user. The right frame displays the key legend. Above the key legend is
an area reserved for a text message. When an option is selected in the left frame, it
is highlighted in white. Often a text message will accompany it. The AMI BIOS Setup
Utility uses a key-based navigation system called "hot keys". Most of the AMI BIOS
setup utility "hot keys" can be used at any time during the setup navigation process.
These keys include <F1>, <F10>, <Enter>, <ESC>, arrow keys, etc.

Note 1: Options printed in Bold are default settings.
Note 2: the AMI BIOS has default text messages built in. Supermicro re-

tains the option to include, omit, or change any of these text messages.)

How To Change the Confi guration Data

The confi guration data that determines the system parameters may be changed by
entering the AMI BIOS Setup utility. This Setup utility can be accessed by pressing
<Del> at the appropriate time during system boot.

4-1

X8DTG-DF User’s Manual

Starting the Setup Utility

Normally, the only visible Power-On Self-Test (POST) routine is the memory test.
As the memory is being tested, press the <Delete> key to enter the main menu of
the AMI BIOS Setup Utility. From the main menu, you can access the other setup
screens. An AMI BIOS identifi cation string is displayed at the left bottom corner of
the screen below the copyright message.

Warning! Do not upgrade the BIOS unless your system has a BIOS-related
issue. Flashing the wrong BIOS can cause irreparable damage to the
system. In no event shall Supermicro be liable for direct, indirect, special,
incidental, or consequential damages arising from a BIOS update. If you
have to update the BIOS, do not shut down or reset the system while the
BIOS is updating. This is to avoid possible boot failure.

4-2 Main Setup

When you fi rst enter the AMI BIOS Setup Utility , you will enter the Main setup screen.
You can always return to the Main setup screen by selecting the Main tab on the
top of the screen. The Main BIOS Setup screen is shown below.

System Overview: The following BIOS information will be displayed:

System Time/System Date

Use this option to change the system time and date. Highlight System Time or Sys­tem Date using the arrow keys. Enter new values through the keyboard and press

<Enter>. Press the <Tab> key to move between fi elds. The date must be entered in
Day MM/DD/YY format. The time is entered in HH:MM:SS format. (Note: The time
is in the 24-hour format. For example, 5:30 P.M. appears as 17:30:00.)

CPU Temperature/System Temperature

This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference only:

CPU 1 Temperature/CPU 2 Temperature

The CPU thermal technology that reports absolute temperatures (Celsius/Fahr­enheit) has been upgraded to a more advanced feature by Intel in its newer
processors. The basic concept is each CPU is embedded by unique temperature
information that the motherboard can read. This ‘Temperature Threshold’ or ‘Tem­perature Tolerance’ has been assigned at the factory and is the baseline on which
the motherboard takes action during different CPU temperature conditions (i.e., by
increasing CPU Fan speed, triggering the Overheat Alarm, etc). Since CPUs can
have different ‘Temperature Tolerances’, the installed CPU can now send informa­tion to the motherboard what its ‘Temperature Tolerance’ is, and not the other way
around. This results in better CPU thermal management.

Supermicro has leveraged this feature by assigning a temperature status to certain
thermal conditions in the processor (Low, Medium and High). This makes it easier
for the user to understand the CPU’s temperature status, rather than by just simply
seeing a temperature reading (i.e., 25

o

C). The CPU Temperature feature will display

the CPU temperature status as detected by the BIOS:
Low – This level is considered as the ‘normal’ operating state. The CPU temperature

is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will
run normally as confi gured in the BIOS (Fan Speed Control).

User intervention: No action required.
Medium – The processor is running warmer. This is a ‘precautionary’ level and

generally means that there may be factors contributing to this condition, but the CPU
is still within its normal operating state and below the CPU ‘Temperature Tolerance’.
The motherboard fans and CPU will run normally as confi gured in the BIOS. The
fans may adjust to a faster speed depending on the Fan Speed Control settings.

User intervention: No action is required. However, consider checking the CPU fans
and the chassis ventilation for blockage.

High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem­perature Tolerance’ has been reached (or has been exceeded) and may activate
an overheat alarm.

User intervention: If the system buzzer and Overheat LED has activated, take action
immediately by checking the system fans, chassis ventilation and room temperature
to correct any problems.

Notes: 1. The system may shut down if it continues for a long period to
prevent damage to the CPU.

4-7 BIOS Recovery

Warning! Do not upgrade the BIOS unless your system has a BIOS-related

issue. Flashing the wrong BIOS can cause irreparable damage to the
system. In no event shall Supermicro be liable for direct, indirect, special,
incidental, or consequential damages arising from a BIOS update. If you
need to update the BIOS, do not shut down or reset the system while the
BIOS is updating. This is to avoid possible boot failure.

How to Recover the AMIBIOS Image (-the Main BIOS
Block)

An AMIBIOS fl ash chip consists of a boot sector block, and a main BIOS code block
(a main BIOS image). The boot sector block contains critical BIOS code, including
memory detection and recovery code to be used to fl ash a new BIOS image if the
original BIOS Image is corrupted. When the system is powered on, the boot sector
code executes fi rst. Once it is completed, the main BIOS code will continue with
system initialization and complete the bootup process.

Notes: BIOS Recovery described below is used when the main BIOS
block crashes. However, when the BIOS Boot sector crashes, you will need
to send the motherboard back to Supermicro for RMA repairs.

4.7.1 Boot Sector Recovery from a USB Device

This feature allows the user to recover a BIOS image using a USB device without
additional utilities needed. A user can download the BIOS image into a USB fl ash
device, and name the fi le "SUPER.ROM" for the recovery process to load the fi le.
A USB fl ash device such as a USB Flash Drive, a USB CDROM or a USB CDRW
device can be used for this purpose,

Insert the USB device that contains the new BIOS image (the ROM fi les) 1.
saved in a root directory into your USB drive.

While turning the power on, press and hold <Ctrl> and <Home> at the same 2.
time until the USB Access LED Indicator comes on. This might take a few
seconds.

Once the USB drive LED is on, release the <Ctrl> and <Home> keys. 3.
AMIBIOS will issue beep codes to indicate that the BIOS ROM fi le is being
updated.

When BIOS fl ashing is completed, the computer will reboot. Do not interrupt 4.
the fl ashing process until it is completed.

4-26

Chapter 4: AMI BIOS

4.7.2 Boot Sector Recovery from an IDE CD-ROM

This process is almost identical to the process of Boot Sector Recovery from a USB
device, except that the BIOS image fi le is loaded from a CD-ROM. Use a CD-R or
CD-RW drive to burn a CD with the BIOS image fi le in it, and name the fi le "SUPER.
ROM" for the recovery process to load the fi le.

4.7.3 Boot Sector Recovery from a Serial Port ("Serial
Flash")

This process, also known as "Serial Flash," allows the user to use a serial port to
load a BIOS image for Boot Sector recovery . This feature is usually used for embed­ded systems that rely on a serial port for remote access and debugging.

Requirements

In order to use Serial Flash for Boot Sector Recovery, you will need to meet the
following requirements.

The "Target system," the system that needs BIOS updates, must have a serial

•

port and "Serial Flash" support embedded in the BIOS image fi le.
The "Host system" should also have a serial port and a terminal program that

•

supports XModem Transfer protocol (Hyper Terminal for the Windows operating
systems, and minicom for Linux/FreeSBD, etc.).

A Null_modem serial cable

•

How to use Serial Flash for Boot Sector Recovery

Connect a Null_modem serial cable between the target system and the host 1.
system that runs the terminal program.

Make sure that the new BIOS Image fi le is accessible for the host system.2.

Start the terminal program on the host system and create a new connection. 3.
Use the following communication parameters for the new connection.

Bits per second: 115200 bits/sec.

•

Data Bits: 8•
Parity: None•
Stop Bit: 1•
Flow Control: None•

b. When asked to confi rm BIOS updating, press <y> to confi rm BIOS

updates.

c. Press <y> again to begin fl ashing BIOS remotely.

Note: Be sure to complete Steps a~c above quickly because
you have a second or less to do so.

6. Once you've completed the instructions given, a screen will display to indicate
that remote fl ashing is starting and the new BIOS fi le is being uploaded.

7. To use Hyper Terminal to transfer the XModem protocol by using the "Send
File" dialog under the "Transfer" menu, follow the instructions below to com­plete XModem transfers.

a. Select the "Transfer" menu and enter <Send>.

b. Specify the location of the ROM fi le and select the proper protocol (XMo-

dem).

c. Press <Send> to start ROM File extraction. (See the picture below.)

4-28

Chapter 4: AMI BIOS

d. Once the ROM fi le extraction is completed, the message: "New BIOS re-

ceived OK" will display.

8. Once remote BIOS fl ash is completed, the system will reboot.

Note: AMIBIOS Serial Flash will work with any terminal communications
program that supports VT-100 and XModem protocols, including protocols
designed for GNU/LINUX & BSD operating systems such as minicom. It
is recommended that the terminal program be confi gured to use the 'CR/
LF' style of line termination.

C-2 Confi guring Supero Doctor III

The Supero Doctor III program is a Web-base management tool that supports
remote management capability. It includes Remote and Local Management tools.
The local management is called the SD III Client. The Supero Doctor III program
included on the CDROM that came with your motherboard allows you to monitor
the environment and operations of your system. Supero Doctor III displays crucial
system information such as CPU temperature, system voltages and fan status. See
the Figure below for a display of the Supero Doctor III interface.

Note: 1 The default user name and password are ADMIN.
Note 2: In the Windows OS environment, the Supero Doctor III settings

take precedence over the BIOS settings. When fi rst installed, Supero Doc-
tor III adopts the temperature threshold settings previously set in BIOS. Any
subsequent changes to these thresholds must be made within Supero Doc­tor, since the SD III settings override the BIOS settings. For the Windows
OS to adopt the BIOS temperature threshold settings, please change the
SDIII settings to be the same as those set in BIOS.
