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 X8DTH-6/X8DTH­6F/X8DTH-i/X8DTH-iF. 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, CPU1 Vtt, CPU2 Vtt, CPU1
DIMM, CPU2 DIMM, 1.1V, 1.5V, 1.8V, 3.3V, 12V, 5V, 3.3 Vsb, and VBAT. Once a
voltage becomes unstable, a warning is given or an error message is sent to the
screen. the user 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 system overheating, be sure to provide adequate air
fl ow to the system.

System Resource Alert

This feature is available when used with Supero D octor III in the Windows OS

Chapter 1: Introduction

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
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 both Windows 2000 and Windows 2003
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

X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF User's Manual

The X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF can accommodate 24-pin ATX power
supplies. Although most power supplies generally meet the specifi cations required
by the CPU, some are inadequate. In addition, the two 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 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 for adequate
power supply to your system. Failure in doing 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 website 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 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 16­byte 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.

1-8 Overview of the Winbond WPCM450 Controller (For
