Performance	2.FEATURES

2.FEATURES

2.1.2Performance

•DDR DRAM Optimized Performance: This motherboard supports a new generation memory, Double Data Rate (DDR) Dynamic Random Access Memory (DDR DRAM). This new memory technology increases performance by executing two actions per clock cycle, resulting in data transfer rates of up to 2.1 GB/s for 133MHz DDR SDRAM and 1.6GB/s for 100MHz DDR SDRAM.

•Onboard Audio: Audio models come with the six-channel C-Media CMI8738 PCI audio controller that supplies HRTF 3D positional audio functions. The chip supports software access to PC DVD 5.1/6.1 and AC-3/DTS via SPDIF.

Other integrative featues include: full DVD playback, PCtel 56K modem, and even Karaoke echo effects. The chip offers 24-bit SPDIF digital recording and playback with additional support for legacy audio SBPRO™ and FM emulator/ DLS wavetable music synthesis. A software package helps setup the multichannel PC sound system.

•ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more Energy Saving Features for operating systems that support OS Direct Power Management (OSPM) functionality. With these features employed in the OS, PCs can be ready around the clock but comply with energy saving standards. To fully utilize the ACPI benefits, use an ACPI-supported OS such as Windows 98.

•Smartcard Reader Connector: This connector that provides the convenience of PS/SC compatible Smart Card security plus support for a multitude of new financial, telephonic, and mobile access services.

•PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series motherboards are PC’99 compliant.

2.1.3Intelligence

•Auto Fan Off: The system fans powers off automatically even in sleep mode. This function reduces both energy consumption and system noise, and is an important feature in implementing silent PC systems.

•Dual Function Power Button: Pushing the power button for less than 4 seconds when the system is in the working state places the system into one of two states: sleep mode or soft-off mode, depending on the BIOS or OS setting (See PWR Button < 4 Secs in 4.5 Power Menu). When the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting.

•Fan Status Monitoring and Alarm: To prevent system overheat and system damage, the CPU and system fans can be monitored for RPM and failure. All fans are set for its normal RPM range and alarm thresholds.

•Power LED (requires ACPI OS support): The power LED indicates the system status.

•Remote Ring-On (requires modem): This allows a computer to be turned on remotely through an internal or external modem. With this benefit on-hand, users can access vital information from their computers anywhere.

•Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPU’s internal thermal diode (on Pentium III and Celeron) to prevent system overheat and system damage.

•Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable voltage to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management.

•Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection.

3.3Hardware Setup Procedure

Complete the following steps before using your computer:

1.Check motherboard settings

2.Install memory modules

3.Install the Central Processing Unit (CPU)

4.Install Expansion Cards

5.Connect ribbon cables, panel wires, and power supply cables

6.Configure the BIOS parameter settings

3.4Motherboard Settings

This section tells you how to change motherboard function settings through the switches and/or jumpers.

WARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To avoid damaging them due to static electricity, follow these precautions whenever you work on your computer.

1.Unplug the computer when working on the internal components.

2.Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling computer components.

3.Hold components by the edges and try not to touch the IC chips on them.

4.Whenever you uninstall any component, place the components on a grounded antistatic pad or in the bag that came with the components.

5.Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

(TIP: When lit, the onboard LED indicates that the system is in suspend or soft-off mode, not powered OFF. See illustration below.)

WARNING! Set the CPU frequency only to the recommended settings. Frequencies other than the recommended CPU bus frequencies are not guaranteed to be stable. Overclocking the processor is not recommended. It may result in a slower speed.

3)Manual CPU Ratio Settings (DSW Switches 5-10)

Set DSW switches (5-10) to use the clock multiplier to coordinate the ratio of bus speeds with CPU settings. Set the DSW switches according to the internal speed of your processor and the bus frequency (133/100MHz).

IMPORTANT:
1. To use this feature, JEN must	be set to Jumper Mode, [1-2].
(See 1, JumperFree™ Mode (JEN)	in 3, HARDWARE SETUP.)

2.When JumperFree mode is enabled, use BIOS setup in place of these switches. (Set Operating Frequency Setting to User Define under 4.4 Advanced Menu in BIOS Setup so you can set the CPU Frequency.)

1.Locate the Socket 462 and open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees).

2.Insert the CPU with the correct orientation. The notched corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge.

CAUTION! The CPU fits in one orientation and should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins.

3.Once completely inserted, press the CPU firmly

and close the socket lever until it snaps into its locked position.

4.Place the CPU fan and heatsink on the CPU. The heatsink should entirely cover the CPU. Carefully attach the heatsink locking brace to the plastic clips on the socket base. With the added weight of the CPU fan and heatsink locking brace, no extra force is required to keep the CPU in place.

CAUTION! Take care not to scrape the motherboard surface when mounting a clamp-style processor fan, or else damage may occur. When mounting a heatsink onto your CPU, make sure that exposed CPU capacitors do not touch the heatsink, or else damage may occur! Refer to heatsink/CPU documentation. NOTE! Do not forget to set the correct Bus Frequency and Multiple (available only on unlocked processors) to avoid start-up problems.

3.7.2Assigning IRQs for Expansion Cards

Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively assigned to one use. In a standard design, there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. If your motherboard has PCI audio onboard, an additional IRQ will be used. If your motherboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments. Conflicts arise between the two PCI groups that will make the system unstable or cards inoperable.

The following table lists the default IRQ assignments for standard PC devices. Use this table when configuring your system and for resolving IRQ conflicts.
