Caution

To avoid damage to the system:  Use the correct AC input voltage range.

To reduce the risk of electric shock:  Unplug the power cord before removing the system chassis

cover for installation or ser vicing. After installation or servicing, cover the system chassis before plugging the power cord.

Battery:  Danger of explosion if battery incorrectly replaced.  Replace only with the same or equivalent type recommend by

the manufacturer.

 Dispose of used batteries according to the battery

manufacturers instructions.

Joystick or MIDI port:  Do not use any joystick or MIDI device that requires more than

10A current at 5V DC . There is a risk of fire for devices that exceed this limit.

FCC and DOC Statement on Class B

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to tr y to correct the interference by one or more of the following measures:

 Reorient or relocate the receiving antenna.  Increase the separation between the equipment and the receiver.  Connect the equipment into an outlet on a circuit different from

that to which the receiver is connected.

 Consult the dealer or an experienced radio TV technician for

help.

Notice:

1. The changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

2. Shielded interface cables must be used in order to comply with the emission limits.

IrDA Interface

The system board is equipped with an IrDA connector for wireless connectivity between your computer and peripheral devices. It supports peripheral devices that meet the HPSIR and ASKIR standard.

USB Ports

The system board supports 4 USB por ts. Two onboard USB por ts are located at the ATX double deck ports of the board. The J19 connector on the system board allows you to connect the optional 3rd and 4th USB ports. These optional USB ports, which are mounted on a card-edge bracket, will be provided as an option. USB allows data exchange between your computer and a wide range of simultaneously accessible external Plug and Play peripherals.

BIOS

 Award BIOS, Windows® 95/98/2000/ME Plug and Play compat-

ible  Supports SCSI sequential boot-up  Flash EPROM for easy BIOS upgrades  Supports DMI 2.0 function  2Mbit flash memory  Vcore and CPU external bus clock selectable in the BIOS

Desktop Management Interface (DMI)

The system board comes with a DMI 2.0 built into the BIOS. The DMI utility in the BIOS automatically records various information about your system configuration and stores these information in the DMI pool, which is a part of the system board's Plug and Play BIOS. DMI, along with the appropriately networked software, is designed to make inventory, maintenance and troubleshooting of computer systems easier.

2.1.2 System Health Monitor Functions

The system board is capable of monitoring the following system health conditions.

 Monitors CPU/system temperature and overheat alarm  Monitors 12V/5V/3.3V/VCORE voltages and failure alarm  Monitors CPU/chassis fan speed and failure alarm  Automatic chassis fan on/off control  Read back capability that displays temperature, voltage and fan

speed

If you want a warning message to pop-up or a warning alarm to sound when an abnormal condition occurs, you must install the VIA Hardware Monitor utility. This utility is included in the CD that came with the system board.

English

2.1.3 Intelligence

CPU Temperature Protection

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

English

CPU Fan Protection

The CPU Fan Protection function has the capability of monitoring the CPU fan during system boot-up and will automatically power-off the system once it has detected that the CPU fan did not rotate. This preventive measure has been added to protect the CPU from damage and insure a safe computing environment.

Over Voltage

The Over Voltage function allows you to manually adjust to a higher core voltage that is supplied to the CPU. Although this function is supported, we do not recommend that you use a higher voltage because unstable current may be supplied to the system board causing damage.

CPU Overclocking

The CPU Overclocking function allows you to adjust the processors bus clock. However, overclocking may result to the processors or systems instability and are not guaranteed to provide better system performance.

Automatic Chassis Fan Off

The chassis fan will automatically turn off once the system enters the Suspend mode.

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.

Important:

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

English

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.

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.

Important:

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

AC Power Failure Recove ry

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.

ACPI STR

English

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 suppor ts the ACPI function allowing 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 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.

English

Virus Protection

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

2.2 Identifying a CPU that Supports the Multiplier Overclocking Function

Not all AMD CPUs support the multiplier overclocking function. Please give special attention to L1 on the CPU. L1s four bridges must be closed (short) in order for the frequency ratio selected on SW1 to take effect. The figure below will help you identify the type of CPU that would allow you to adjust its frequency ratio.

L1s four bridges closed (short).

L1s four bridges open.
