Introduction

Features

The Watchdog Timer function allows your

application to regularly “clear” the system at the set time interval. If the system hangs or fails to function, it will reset at the set time interval so that your system will continue to operate.

The system board supports Intel processors with Hyper-Threading Technology. Ena-

bling 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

Please refer to Appendix A for information about enabling the functionality of the Hyper-Threading Technology. For more information on Hyper-Threading Technology, go to: www.intel.com/info/hyperthreading.

Double Data Rate SDRAM (DDR SDRAM) 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 doubling the speed of data transfer.

The Intel 865G Northbridge chip comes integrated with the Intel

Extreme Graphics 2 technology providing 3D graphics with sharp images, fast rendering, smooth motion and extreme detail. It supports the latest 2D and 3D APIs, delivering real-life environment and character effects.

Introduction

The audio jacks at the rear panel will

support 5.1-channel audio only when the audio utility is configured to support this function. The mic-in at the rear will be disabled. Use the front audio’s mic-in jack.

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 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.

The dual Realtek RTL8110SC PCI Gigabit LAN controllers support up to 1Gbps data transmis-

sion.

AGP is an interface designed to support high per-

formance 3D graphics cards. It utilizes a dedicated pipeline to access system memory for texturing, z-buffering and alpha blending. The AGP slot suppor ts 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. It handles large amounts of graphics data with the following features:

• Pipelined memory read and write operations that hide memory access latency.

• Demultiplexing of address and data on the bus for nearly 100 percent efficiency.

AGP in this system board will deliver faster and better graphics to your PC.

Introduction

The system board is equipped with an IrDA connec-

tor 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.

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.

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:

The 5V_standby power source of your power supply must support ≥720mA.

This feature allows the network to remotely

wake up a Soft Power Down (Soft-Off) PC. It is supported via the onboard LAN port, via a PCI LAN card that uses the PCI PME (Power Management Event) signal or via a LAN card that uses the Wake-On-LAN connector. However, if your system is in the Suspend mode, you can power-on the system only through an IRQ or DMA interrupt.

Important:

The 5V_standby power source of your power supply must support ≥720mA.

This function allows you to use the PS/2 keyboard or PS/2 mouse to power-on the sys-

tem.

Introduction

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 5V_standby power source of your power supply must support

≥

1.5A. For 3 or more USB ports, the

5V_standby power source of your power supply must support

≥

2A.

The RTC installed on the system board allows your system to automatically power-on on the set date

and time.

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

®®

98/2000/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

®®

98/2000/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 5V_standby power source of your power supply must support ≥720mA.

When power returns after an AC power failure, you may choose to either power-on the system manually or let the system power-on

automatically.

Important:

Do not force the CPU into the socket. Forcing the CPU into the socket may bend the pins and damage the CPU.

10. Once the CPU is in place, move the cover down.

Hardware Installation

Installing the Fan and Heat Sink

The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circulation across the CPU and heat sink, the CPU will overheat damaging both the CPU and system board.

Note:

• Use only certified fan and heat sink.

• The fan and heat sink package usually contains the fan and

heat sink assembly, and an installation guide. If the installation procedure in the installation guide differs from the one in this section, please follow the installation guide in the package.

1. Before you install the fan / heat sink, you must apply a thermal paste onto the top of the CPU. The thermal paste is usually supplied when you purchase the CPU or fan heat sink assembly. Do not spread the paste all over the surface. When you later place the heat sink on top of the CPU, the compound will disperse evenly.

Do not apply the paste if the fan / heat sink already has a patch of thermal paste on its underside. Peel the strip that covers the paste before you place the fan / heat sink on top of the CPU.

11. Push the lever down to lock the socket. The lever should hook

onto the side tab to indicate that the CPU is completely secured in the socket.

Hardware Installation

2. Place the heat sink on top of the CPU. The 4 studs around the heat sink which are used to secure the heat sink onto the system board must match the 4 mounting holes around the socket.

Position each stud so that the groove faces the heat sink then push it down firmly until it clicks into place.

Note:

You will not be able to secure the fan and heat sink assembly in place if the groove is not facing the heat sink.

3. Connect the CPU fan’s cable connector to the CPU fan connector on the system board.
