1.2 Special Features of the System Board
Hyper-Threading Technology Functionality Requirements
The system board supports Intel processors with Hyper-Threading
Technology. Enabling the functionality of Hyper-Threading Technology
for your computer system requires ALL of the following platforms.
Components:
• CPU - an Intel
®
Pentium® 4 Processor with HT Technology
• Chipset - an Intel® chipset that supports HT Technology
• BIOS - a BIOS that supports HT Technology and has it enabled
• OS - an operating system that includes optimizations for HT
Technology
Refer to Appendix A for information about enabling the functionality
of the Hyper-Threading Technology. For more information on HyperThreading Technology, go to: www.intel.com/info/hyperthreading.
CPU Overheat Protection
CPU Overheat Protection has the capability of monitoring the CPU’s
temperature during system boot up. Once the CPU’s temperature
exceeded the temperature limit pre-defined by the CPU, the system
will automatically shutdown. This preventive measure has been added
to protect the CPU from damage and insure a safe computing
environment.
DDR
DDR (Double Data Rate) is a type of SDRAM that doubles the
data rate through reading and writing at both the rising and falling
edge of each clock. This effectively doubles the speed of operation
therefore providing two times faster data transfer.
6-channel Audio
The audio jacks at the rear panel will support 6-channel audio only
when the audio utility is configured to support this function. The micin at the rear will be disabled. Use the front audio’s mic-in jack.

Introduction
11
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be converted first to an
analog format. This prevents the quality of the audio signal from
degrading whenever it is converted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device. The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.
Serial ATA Interface
Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s.
IrDA Interface
The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification supports data
transfers of 115K baud at a distance of 1 meter.
USB Ports
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1
supports 12Mb/second bandwidth while USB 2.0 supports 480Mb/
second bandwidth providing a marked improvement in device
transfer speeds between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
AGP (Accelerated Graphics Port)
AGP is an interface designed to support high performance 3D
graphics cards. It utilizes a dedicated pipeline to access system
memory for texturing, z-buffering and alpha blending. The AGP slot
supports AGP 8x (0.8V) with up to 2.13GB/sec. bandwidth and
AGP 4x (1.5V) with up to 1066MB/sec. bandwidth for 3D graphics
applications. AGP in this system board will deliver faster and better
graphics to your PC.

Dual Function Power Button
Depending on the setting in the “Soft-Off By PWR-BTTN” field of
the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥720mA.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power
Down (Soft-Off) PC. It is suppor ted via the onboard LAN port or
via a PCI LAN card that uses the PCI PME (Power Management
Event) signal. However, if your system is in the Suspend mode, you
can power-on the system only through an IRQ or DMA interrupt.
Important:
The 5VSB power source of your power supply must support
≥
720mA.
Wake-On-PS/2 Keyboard/Mouse
This function allows you to use the PS/2 keyboard or PS/2 mouse
to power-on the system.
Important:

Wake-On-USB Keyboard/Mouse
This function allows you to use a USB keyboard or USB mouse to
wake up a system from the S3 (STR - Suspend To RAM) state.
Important:
• If you are using the Wake-On-USB Keyboard/Mouse
function for 2 USB ports, the 5VSB power source of your
power supply must support ≥1.5A.
• If you are using the Wake-On-USB Keyboard/Mouse
function for 3 or more USB ports, the 5VSB power source
of your power supply must support ≥2A.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time.
ACPI STR
The system board is designed to meet the ACPI (Advanced
Configuration and Power Interface) specification. ACPI has energy
saving features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management. Currently, only Windows
®®
®®
®
2000/ME/XP
supports the ACPI function. ACPI when enabled in the Power
Management Setup will allow you to use the Suspend to RAM
function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting “Standby”
when you shut down Windows
®®
®®
®
2000/ME/XP without having to go
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of
storing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The
operating session will resume exactly where you left off the next time
you power-on the system.
Important:
The 5VSB power source of your power supply must support
≥
1A.
