Refer to chapter 4 for instructions on using the DMI utility.

Introduction

1.1.2 Intelligence

Dual Function Power Button

Depending on the setting in the “Soft-Off By PWRBTN” 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 through an internal or external modem. Refer to “Wake-On-Ring Connector” in chapter 2 and “Resume On LAN/Ring” (“IRQ/Event Activity Detect” field) in the Power Management Setup section in chapter 3 for more information.

Important:

If you are using a modem add-in card, the 5VSB power source of your power supply must support ≥720mA.

Wake-On-LAN

The Wake-On-LAN function allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. Your LAN card must support the remote wakeup function. Refer to “Wake-On-LAN Connector” in chapter 2 and “Resume On LAN/Ring” (“IRQ/Event Activity Detect” field) in the Power Management Setup section in chapter 3 for more information.

Important:

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

Introduction

Wake-On-PS/2 Keyboard/Mouse

This function allows you to use the PS/2 keyboard or PS/2 mouse to wake up the system from the S5 state. Refer to “Jumper Settings for Selecting the PS/2 Power” in chapter 2 and “PS2KB Wakeup Select” (“IRQ/Event Activity Detect” field) in the Power Management section in chapter 3 for more information.

Important:

• If you forgot the password, you must power-off the system, unplug the power cord and clear the CMOS data. Follow the steps in the “Jumper Settings for Clearing CMOS Data” section in chapter 2.

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

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. Refer to “USB Resume from S3” (“IRQ/Event Activity Detect” field) in the Power Management Setup section in chapter 3 for more information.

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 mainboard allows your system to automatically power-on on the set date and time. Refer to “Resume On- Alarm” (“IRQ/Event Activity Detect” field) in the Power Management Setup section in chapter 3 for more information.

Introduction

ACPI STR

The mainboard 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 Plugand-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. Refer to “Using the Suspend to RAM Function” in appendix A for more information.

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. Refer to “PWR Lost Resume State” in the Power Management Setup section in chapter 3 for more information.

Virus Protection

Most viruses today destroy data stored in hard drives. The mainboard is designed to protect the boot sector and partition table of your hard disk drive.

Hardware Installation

Warning:

Electrostatic discharge (ESD) can damage your mainboard, processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system chassis throughout any procedures requiring ESD protection.

2.2 System Memory

DDR 2

DDR 1

The system board is equipped with two 184-pin DDR SDRAM DIMM (Dual In-line Memory Module) sockets that suppor t 2.5V 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.

Refer to chapter 1 (System Memory section) for detailed specification of the memory supported by the system board.

Hardware Installation

2.2.1 Installing the DIM Module

A DIM module simply snaps into a DIMM socket on the system board. Pin 1 of the DIM module must correspond with Pin 1 of the socket.

Notch

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.

The system board is also equipped with J13 for connecting 2 additional external USB 2.0/1.1 por ts. The USB 2.0/1.1 ports, which are mounted on a card-edge bracket, will be provided as an option. If you wish to use the optional USB 2.0/1.1 ports, install the cardedge bracket to the system chassis then insert the connector that is attached to the USB 2.0/1.1 port cables to J13. The USB ports’ cable connector can be inserted only if pin 1 of the connector is aligned with pin 1 of J13. Now connect the interface cable connector of your USB 2.0/1.1 device to the USB 2.0/1.1 port that is on the bracket.

You can enable or disable the USB ports in the Integrated Peripherals submenu (“OnChip USB Controller” field) of the BIOS.

The Wake-On-USB Keyboard/Mouse function allows you to use a USB keyboard or USB mouse to wake up a system from the S3 (STR - Suspend To RAM) state.

To use this function:

“USB Resume from S3” (“IRQ/Event Activity Detect” field) in the Power Management Setup submenu of the BIOS must be set to Enabled. Refer to chapter 3 for more information.

Hardware Installation

2.5.4 Serial Ports

COM 1

Serial Port

COM 2

(J4)

The built-in serial por ts are RS-232C asynchronous communication ports with 16C550A-compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices. You can select the serial ports’ I/O address in the Integrated Peripherals submenu (“Super IO Device” field) of the BIOS.

Connecting the Serial Ports

The system board is equipped with an onboard serial port (J3 Teal/Turquoise) for COM 1 primary serial port located at the ATX double deck ports of the board. It is also equipped with a 9-pin connector at location J4 for COM 2 secondar y serial por t.

One card-edge bracket, mounted with a serial port cable, is provided with the system board. If you want to use the secondary serial por t, connect the serial port cable to connector J4. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of connector J4. Mount the card-edge bracket to the system chassis.

Hardware Installation

2.5.5 Parallel Port
