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-QF. 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), VP1 DIMM, VP2 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-QF 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.

Note 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.

Note: For more information on IPMI confi guration, please refer to the Em-
bedded IPMI User's Guide posted on our website at http://www.supermicro.
com/support/manuals/.

1-8 Super I/O

The Super I/O supports 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

2-6 Connecting Cables

Power Connectors

A 24-pin main power supply connector(JPW1)
and two 8-pin CPU PWR connectors (JPW2/
JPW3) on the motherboard. These power
connectors meet the SSI EPS 12V specifi ca-
tion. All these three power connectors must
be connected to your power supply to ensure
adequate power supply to your system. See
the table on the right for pin defi nitions.

Warning: To prevent damage to the
power supply or motherboard, please
use a power supply that contains a
24-pin and two 8-pin power connec­tors. Be sure to connect these con­nectors to the 24-pin (JPW1) and the
two 8-pin (JPW2,JPW3) power con­nectors on the motherboard. Failure
in doing so will void the manufacturer
warranty on your power supply and
motherboard.

Fan Headers

The X8DTG-QF has ten chassis/system fan
headers (Fan1 ~ Fan10) on the motherboard.
Fan 7 and Fan 8 are CPU Fans. All these are
4-pin fans headers which are backward com­patible with the traditional 3-pin fans. However,
fan speed control is available for 4-pin fans
only . 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
for pin defi nitions.

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 ju mpers, " Closed"
means the jumper is on and "Open"
means th e jumpe r is of f the pi ns.

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact
pads to prevent t he accident al clearin g of CMOS. To clear CMOS , use a metal
objec t such as a sma ll screwdr iver to touc h both pad s at the same t ime to shor t
the co nnec ti on. A lways rem ove the AC p ower c ord f rom t he syste m befo re cl ear­ing CMOS.

Note 1. For an ATX power supply, you must completely shut down the
system, remove the AC power cord and then short JBT1 to clear CMOS.

Note 2. Be sure to remove the onboard CMOS Battery before you short
JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog (JWD) is a system monitor that can
reboot the system when a software application
hangs. Close Pins 1-2 to reset the system if an

BIOS

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DTG-QF. 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.

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

Temperature/System Temperature

o

C above the threshold temperature as predefi ned by the CPU

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. 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).

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’.

4-17

X8DTG-QF User’s Manual

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.

2. The information provided above is for your reference only. For more
information on thermal management, please refer to Intel’s Web site at
www.Intel.com.

Fan Speed Control Modes

This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlative. When the
CPU on-die temperature increases, the fan speed will also increase for effective
system cooling. Select "Full Speed/FS" to allow the onboard fans to run at full
speed for maximum cooling. The FS setting is recommended for special system
confi guration or debugging. Select "Performance/PF" for better system cooling. The
PF setting is recommended for high-power-consuming and high-density systems.
Select "Balanced/BL" for the onboard fans to run at a speed that will balance the
needs between system cooling and power saving. The BL setting is recommended
for regular systems with normal hardware confi gurations. Select "Energy Saving/ES"
for best power effi ciency and maximum quietness. The Options are: Full Speed/FS,
Performance/PF, Balanced/BL, and Energy Saving/ES.

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.

4-27

X8DTG-QF User’s Manual

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

BIOS Error Beep Codes

During the POST (Power-On Self-Test) routines, which are performed each time
the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue the
boot-up process. The error messages normally appear on the screen.

Fatal errors will not allow the system to continue the boot-up procedure. If a
fatal error occurs, you should consult with your system manufacturer for possible
repairs.

C-2 Confi guring Supero Doctor III

The Supero Doctor III program is a Web-based 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.
