1-4 Special Features

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when
AC power is lost and then restored to the system. You can choose for the system
to remain powered off (in which case you must hit the power switch to turn it back
on) or for it to automatically return to a power- on state. See the Advanced BIOS
Setup section to change this setting. The default setting is Last State.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the X8DTN+. 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, +12V, -12V 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.

Warning! To avoid possible system overheating, be sure to provide ad­equate airfl ow to the system.

System Resource Alert

This feature is available when used wit h Supero Doctor III in the W indows 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 c onfi gure
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.

1-6 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.

Wake-On-LAN (WOL)

Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN traffi c is kept to
a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

1-11

X8DTN+ User's Manual

WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.

Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power
supply.

1-7 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 X8DTN+ can accommodate 24-pin ATX power supplies. Although most power
supplies generally meet the specifi cations required by the CPU, some are inad-
equate. In addition, the 12V 8-pin power connections are also required to ensure
adequate power supply to the system. Also your power supply must supply 1.5A
for the Ethernet ports.

Warning: To prevent damage to your 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 power connectors to the 24-pin and the two
8-pin power connectors on your motherboard for adequate power supply
to your system. Failure to do so will void the manufacturer warranty on
your power supply and motherboard.

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
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.

1-8 Super I/O

The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive
controller that is compatible with industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock genera­tor, drive interface control logic and interrupt and DMA logic. The wide range of
functions integrated onto the Super I/O greatly reduces the number of components
required for interfacing with fl oppy disk drives. The Super I/O supports 360 K, 720
K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s
or 1 Mb/s. It also provides two high-speed, 16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt

1-12

Chapter 1: Introduction

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 provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage­ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

2-3 Mounting the Motherboard into the Chassis

All motherboards have standard mounting holes to fi t different types of chassis.
Make sure that the locations of all mounting holes for 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 that the metal standoffs click in or are screwed in tightly. Then
use a screwdriver to secure the motherboard onto the motherboard tray. (See the
layout on the right for mounting hole locations.)

Note: Some components are very close to the mounting holes. Please take
all necessary precautionary measures to avoid damaging these compo­nents when installing the motherboard into the chassis.

Fan Headers

The X8DTN+ has six chassis/system
fan headers (Fan1 to Fan6) and two
CPU fans (Fan7/Fan8) on the moth­erboard. All these 4-pin fans headers
are backward compatible with the
traditional 3-pin fans. However, 3-pin
fans do not support fan speed control.
Fan speed control is available for 4-pin
fans only. The onboard 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 mpe rs,
"Closed" means the jumper
is on and "Open" means
the jump er is of f the p ins.

Chapter 4: AMI BIOS

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DTN+. 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
confi 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. (Note:
the AMI BIOS has default text messages built in. Supermicro retains the option to
include, omit, or change any of these text messages.)

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: Options printed in Bold are default settings.

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

X8DTN+ 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

manufacturer to give the CPU and system fans additional time needed for CPU
and system cooling. In both the alarms above, please take immediate action
as shown below.

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 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.

o

C above the threshold temperature as predefi ned by the CPU

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

4-17

X8DTN+ User’s Manual

seeing a temperature reading (i.e., 25oC). 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.

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 are those which 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.

These fatal errors are usually communicated through a series of audible beeps.
The numbers on the fatal error list correspond to the number of beeps for the

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.
