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 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 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.

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.

1-11

X8DTN+ User's Manual

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.

1-7 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
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.

2-1 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.

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.
