1 Introduction

1.1.3 Intelligence

CPU Fan Protection

The CPU Fan Protection function has the capability of monitoring the CPU fan when the system boots. Once it has detected that the CPU fan did not rotate, 5 warning beeps will sound then the system will automatically power-off. This preventive measure has been added to protect the CPU from damage and insure a safe computing environment.

CPU Temperature Protection

The CPU Temperature Protection function has the capability of monitoring the CPU’s temperature during system boot-up. Once the system has detected that the CPU’s temperature exceeded the temperature limit defined in the BIOS, 5 warning beeps will sound then the system will automatically power-off.

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.

12

Introduction 1

Wake-On-LAN

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 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:

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

Wake-On-USB Keyboard

This function allows you to use a USB keyboard to wake up a system from the S3 (STR - Suspend To RAM) state.

Important:

If you are using the Wake-On-USB Keyboard 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 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.

13

1 Introduction

ACPI

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® 98SE/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® 98SE/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.

AC Power Failure Recovery

When power returns after an AC power failure, you may choose to either power-on the system manually, let the system power-on automatically or return to the state where you left off before power failure occurs.

ON

The system board supports DDR SDRAM DIMM. 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 four DDR DIMM sockets on the system board are divided into 2 channels:

Channel 0 - DDR 1 and DDR 2

Channel 1 - DDR 1 and DDR 2

19

2 Hardware Installation

The system board supports the following memory interface.

Single Channel (SC)

Data will be accessed in chunks of 64 bits (8B) from the memory channels.

Virtual Single Channel (VSC)

If both channels are populated with different memory configurations, the MCH defaults to Virtual Single Channel.

Dual Channel (DC)

Dual channel provides better system performance because it doubles the data transfer rate.

Dynamic Mode Addressing

This mode minimizes the overhead of opening/closing pages in memory banks allowing for row switching to be done less often.

Single Channel

DIMMs are on the same channel.

 

DIMMs in a channel can be identical or

 

completely different.

 

Not all slots need to be populated.

 

 

Virtual Single

DIMMs of different memory configura-

Channel

tions are on different channels.

 

Odd number of slots can be popu-

 

lated.

 

 

Dual Channel

DIMMs of the same memory configu-

 

ration are on different channels.

 

 

Dynamic Mode

In single channel, requires even

Addressing

number or rows (side of the DIMM)

 

populated. This mode can be enabled

 

with 1 SS, 2 SS or 2 DS.

 

 

 

In VSC mode, both channels must have

 

identical row structure.

Pin 1

1.Pull the “tabs” which are at the ends of the socket to the side.

2.Position the DIMM above the socket with the “notch” in the module aligned with the “key” on the socket.

3.Seat the module vertically into the socket. Make sure it is completely seated.The tabs will hold the DIMM in place.

2 Hardware Installation

2.3 CPU

2.3.1 Overview

The system board is equipped with a surface mount 478-pin CPU socket. This socket is exclusively designed for installing an Intel processor.

2.3.2Installing the CPU

1.Locate Socket 478 on the system board.

2.Unlock the socket by pushing the lever sideways, away from the socket, then lifting it up to a 90o angle. Make sure the socket is lifted to at least this angle otherwise the CPU will not fit in properly.

Lever

24

Hardware Installation 2

3.Position the CPU above the socket then align the gold mark on the corner of the CPU (designated as pin 1) with pin 1 of the socket.

Important:

Handle the CPU by its edges and avoid touching the pins.

Gold mark

Pin 1

4. Insert the CPU into the socket until it is seated in place. The CPU will fit in only one orientation and can easily be inserted without exerting any force.

Important:

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

25

2 Hardware Installation

5.Once the CPU is in place, push down the lever to lock the socket. The lever should click on the side tab to indicate that the CPU is completely secured in the socket.

2.3.3 Installing the Fan and Heat Sink

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

Note:

Only use Intel® certified fan and heat sink.

An Intel® boxed processor package contains a retention mechanism, heat sink, fan and 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.

If you are installing a non-boxed processor, the heat sink, fan and retention mechanism assembly may look different from the one shown in this section but the procedure will more or less be the same.

26

Hardware Installation 2

1.The system board comes with the retention module base already installed.

2.Position the fan / heat sink and retention mechanism assembly on the CPU, then align and snap the retention legs’ hooks to the retention holes at the 4 corners of the retention module base.

Note:

You will not be able to snap the hooks into the holes if the fan / heat sink and retention mechanism assembly did not fit properly onto the CPU and retention module base.
