Caution

To avoid damage to the system:

• Use the correct AC input voltage r ange

To reduce the risk of electr ic shock:

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

Battery:

• Danger of explosion if batter y incor rectly replaced.

• Replace only with the same or equivalent type recommend

the manufacturer.

• Dispose of used batteries according to the battery manufacturer’s

instructions.

Joystick or MIDI por t:

• 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 Par t 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 par ticular 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 par ty 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.

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/XP Plug and Play compatible

• 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

English

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

• Monitors ±12V/±5V/3.3V/CPU/VBAT(V)/5VSB(V) voltages

• Monitors CPU/chassis fan speed

• 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 “Hardware Monitor” utility. This utility is included in the CD that came with the system board.

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 war ning beeps.

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.

English

Over V oltage

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.

RTC Timer to Power-on the System
