2-3 Special Features

Recovery from AC Power Loss

The Basic I/O System (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.

2-4 PC Health Monitoring

This section describes the PC health monitoring features of the motherboard. 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 DIMM, CPU2 DIMM, 1.1V, 3.3V, 1.5V, +5V, +12V, 3.3V
Standby, 5V Standby, 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 the
Hardware Monitoring section 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 the CPU from overheating. The onboard chassis thermal circuitry
can monitor the overall system temperature and alert The user when the chassis
temperature is too high.

Note: 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 Doctor III in the Windows OS

Chapter 2: Overview

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 predefi ned range.

2-5 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 also
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 2003, Windows XP, Windows Vista
and Windows 2008 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.

2-6 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.

The X8DTU-LN4F+ motherboard accommodates 24-pin ATX power supplies.
Although most power supplies generally meet the specifi cations required by the
CPU, some are inadequate. In addition, 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! 1. 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.

2-13

X8DTU-LN4F+ Motherboard User ’s Manual

2. To provide adequate power to the add-on cards installed on the mother­board, please connect the UIOP PWR connector to the power supply.

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.

2-7 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
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.

2-8 Overview of the Nuvoton WPCM450 Controller

The Nuvoton WPCM450 Controller is a Baseboard Management Controller (BMC)
that supports the 2D/VGA-compatible Graphics Core with the PCI interface,
Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules. With
blade-oriented Super I/O capability built-in, the WPCM450 Controller is ideal for
legacy-reduced server platforms.

The WPCM450 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, and Platform Environment Control Interface (PECI) buses.
