Introduction to ASUS Smart Series Motherboards
Performance
•SDRAM Optimized Performance:ASUS Smart Series motherboards support the new generation memory—Synchronous Dynamic Random Access Memory (SDRAM)—which increases the data transfer rate to 800MB/sec max using PC100-compliant SDRAM.
•Double the IDE Transfer Speed:ASUS Smart Series motherboards with ALi’s Aladdin V chipset improves IDE transfer rate using UltraDMA/33 Bus Master IDE, which can handle data transfer up to 33MB/sec. The best of all is that this new technology is compatible with existing ATA-2 IDE specifications so there is no need to upgrade current hard drives or cables.
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master buses to memory to CPU.
•ACPI Ready:ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS Smart Series motherboards. ACPI provides more Energy Saving Features for the future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality. With these features implemented in the OS, PCs can be ready around the clock, yet satisfy all the energy saving standards. To fully utilize the benefits of ACPI, an OS that supports ACPI, such as Windows 98, must be used.
•PC’98 Compliant: Both the BIOS and hardware levels of the ASUS Smart Series motherboards meet PC’98 compliancy. The new PC’98 requirements for systems and components are based on the following high-level goals: Support for Plug and Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for Windows 95/Windows 98 and Windows NT.
Intelligence (with optional Hardware Monitor only)
•Fan Status Monitoring and Alarm: To prevent system overheat and system damage, the CPU fan and system fans are monitored for RPM and failure. Each fan can be set for its normal RPM range and alarm thresholds.
•Temperature Monitoring and Alert: To prevent system overheat and system damage, there is a heat sensor under the CPU and on the motherboard itself to monitor CPU and system temperature to make sure the system is operating at a safe heat level to avoid any failures triggered by extremely high temperature.
•Chassis intrusion Detection: Supports chassis-intrusion monitoring through LDCM and the optional ASUS CIDB chassis sensor module.

II.FEATURES
•Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable current to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management.
•System Resources Alert:Today’s operating systems, such as Windows 95, Windows NT, and OS/2, require much more memory and hard drive space to present enormous user interfaces and run large applications. The system resource monitor will warn the user before the system resources are used up to prevent possible application crashes. Suggestions will give the user information on managing their limited resources more efficiently.
•CPU Slow Down:When CPU fans or system fans malfunction, the system will deactivate the CPU Clock line to decrease CPU utilization to the speed upon detection of system overheat. This will prevent CPU damage from system overheat. The CPU utilization will restore normal operations when temperature falls below a safe level.
•Auto Fan Off: The system fans will power 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 (requires ATX power supply): The system can be in one of two states, one is Sleep mode and the other is Soft-Off mode. Pushing the power button for less than 4 seconds places the system into Sleep mode. When the power button is pressed for more than 4 seconds, it enters the Soft-Off mode.
•Remote Ring On (requires ATX power supply):This feature allows a computer to be turned on remotely through a modem. With this benefit on hand, any user can access vital information from their computer from anywhere in the world!
•Message LED (requires ACPI-supported OS): Chassis LEDs now act as information providers. Through the way a particular LED illuminates, the user can determine the stage the computer is in. A simple glimpse provides useful information to the user.

WARNING! Computer motherboards, baseboards and components, such as SCSI cards, contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer.
1.Unplug your computer when working on the inside.
2.Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.
3.Hold components by the edges and try not to touch the IC chips, leads or connectors, or other components.
4.Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.
Jumper Settings
1.Real Time Clock (RTC) RAM (CLRTC)

5.CPU External (BUS) Frequency Selection (FS3, FS2, FS1, FS0)
These jumpers tell the clock generator what frequency to send to the CPU, chipset, and AGP. These allow the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).
6.CPU to BUS Frequency Multiple (BF0, BF1, BF2)
These jumpers set the frequency ratio between the Internal frequency of the CPU and the External frequency (called the BUS Clock) within the CPU. These must be set in conjunction with the jumpers for CPU External (BUS) Frequency Selection.

2.System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of either 8, 16, 32, 64, 128MB, or 256MB to form a memory size between 8MB and 768MB. One side (with memory chips) of the DIMM takes up one row on the motherboard.
To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and make the proper settings through “Chipset Features Setup” in BIOS setup.
Memory speed setup is recommended through SDRAM Configuration under “Chipset Features Setup” in BIOS setup.
IMPORTANT (see General DIMM Notes below)
• To make using bus speeds ≥95MHz possible, SDRAMs used must be compatible with the current Intel PC100 SDRAM specification..
Install memory in any combination as follows:

NOTES
•At the time this User’s Manual was written, 256MB DIMMs are either available as registered memory or 128Mbit DIMMs.
•DIMMs that have more than 18 chips are not supported on this motherboard.
•For the system CPU bus to operate ≥95MHz, use only PC100-compliant DIMMs.
When this motherboard operates at ≥95MHz, most system will not even boot if noncompliant modules are used because of the strict timing issues involved under these speeds. If your DIMMs are not PC100-compliant, set the CPU bus frequency to 66MHz for system stability.
•ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.
•SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips.
•BIOS shows SDRAM memory on bootup screen.
•Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64, 128, 256MB.

III. INSTALLATION
DIMM Memory Installation Procedures:
Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation as shown. DRAM SIMM modules have the same pin contacts on both sides. SDRAM DIMMs have different pin contacts on each side and therefore have a higher pin density.

III.INSTALLATION
3.Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible with ZIF Socket 5 processors. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before you turn on your system.
WARNING! Without a fan circulating air on the CPU, the CPU can overheat and cause damage to both the CPU and the motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree right angle. Insert the CPU with the correct orientation as shown. Use the notched corner of the CPU with the white dot as your guide. The white dot should point toward the end of the lever. Notice that there is a blank area where one hole is missing from that corner of the square array of pin holes and a “1” printed on the motherboard next to that corner. Because the CPU has a corner pin for three of the four corners, the CPU will only fit in the one orientation as shown. The picture is for reference only; you should have a CPU fan that will cover the face of the CPU. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, hold down on the fan and close the socket’s lever.
IMPORTANT: You must set jumpers for “CPU to BUS Frequency Ratio” and jumpers for “BUS Frequency Selection” depending on the CPU that you install.
CAUTION! Be careful not to scrape the motherboard when mounting a clampstyle processor fan or else damage may occur to the motherboard.
