2.FEATURES
2.1.2Special Features
•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 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 ACPI-supported OS, such as Windows 98 must be used.
•Easy Installation: Incorporates BIOS that supports autodetection of hard disk drives, PS/2 mouse, and Plug and Play devices to make the setup of hard disk drives, expansion cards, and other devices virtually automatic.
•PC’98 Compliant: Both the BIOS and hardware levels of ASUS smart series motherboards meet PC’98 compliancy. The 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 Windows95/98/NT .
•Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through the onboard SYMBIOS firmware.
2.1.3 Performance Features
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master busses to the memory and processor.
•High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus Master IDE can handle rates up to 33MB/s. This motherboard with its chipset and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to 66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA and with existing DMA devices and systems so there is no need to upgrade current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin 80-conductor cable to be enabled and/or for UltraDMA Mode 4.)
•VCM/HSDRAM Optimized Performance: Supports the new generation memory, NEC’s Virtual Channel (VC) SDRAMs (Synchronous Dynamic Random Access Memory) or Enhanced Memory System’s High-speed DRAMs (HSDRAMs) for higher system performance at minimal cost premium.

2.FEATURES
2.1.4Intelligence
•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: 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, power supply, and system fans can be monitored for RPM and failure. All fans are set for its normal RPM range and alarm thresholds.
•PS/2 Keyboard/Mouse Power Up: Keyboard/Mouse Power Up can be enabled or disabled to allow the computer to be powered on by either pressing the space bar, Ctrl-Esc, or Power keys (see 4.5.1 Power Up Control).
•Message LED (requires ACPI OS support): Turbo LEDs now act as information providers. Through the way a particular LED illuminates, the user can determine if there are messages waiting in the mailbox. A simple glimpse provides useful information to the user.
•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 from anywhere in the world!
•System Resources Alert: Today’s operating systems such as Windows 95/98/ 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.
•Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPU’s internal thermal diode (on Pentium III, Pentium II (Deschutes), and PPGA370 Celeron in conjunction with the ASUS S370-133 CPU card) 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
Before using your computer, you must complete the following steps:
•Check Motherboard Settings
•Install Memory Modules
•Install the Central Processing Unit (CPU)
•Install Expansion Cards
•Connect Ribbon Cables, Panel Wires, and Power Supply
3.4Motherboard Settings
WARNING! Computer motherboards and expansion 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.
5.Ensure that the ATX power supply is switched off before you plug in or remove the ATX power connector on the motherboard.
Motherboard Feature Settings (U12)
The motherboard’s onboard functions are either adjusted through jumpers or DIP switches. When using DIP switches, the white block represents the switch’s position. The example below shows all the switches in the OFF position.

2.AGP Bus Frequency Setting (U12-Switches 5&6)
This option sets the frequency ratio between the AGP bus frequency and the DRAM (CPU bus) frquency. The default sets the AGP frequency to be 2/3 of the DRAM frequency. When the CPU/DRAM frequency is set to 66MHz, set Switch 5 to [ON] and Switch 6, [ON]. See the processor table on the following page.

3.CPU Bus Frequency Selection (U12–Switches 7, 8, 9, 10)
This option tells the clock generator what frequency to send to the CPU, DRAM, and PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock multiplied by the BUS Multiple equals the CPU’s Internal frequency (the advertised CPU speed).
NOTE: In JumperFree mode, all dip switches must be set to OFF.

3.HARDWARE SETUP
3.5System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Four sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 2GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NEC’s Virtual Channel (VC) SDRAMs and Enhanced Memory System’s High-speed DRAMs (HSDRAMs).
Memory speed setup is recommended through 4.4.1 Chip Configuration.
IMPORTANT (see General DIMM Notes below for more)
•SDRAMs used must be compatible with the current Intel PC133 SDRAM specification.
•DO NOT attempt to mix registered SDRAMs with VC SDRAMs.
Install memory in any combination as follows:

General DIMM Notes
•DIMMs that have more than 18 chips are not supported on this motherboard.
•For the system bus to operate at 100 MHz, use only PC100or PC133-compliant DIMMs; for the system bus to operate at 133MHz, use PC133-compliant DIMMs.
•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, 64,128, or 256MB; double-sided come in 32, 64, 128, 256, or 512MB.

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.

3.6.6 Recommended Heatsinks for Slot 1 Processors
The recommended heatsinks for the Slot 1 processors are those with three-pin fans that can be connected to the motherboard’s CPU fan connector. These heatsinks dissipate heat more efficiently and with an optional hardware monitor, they can monitor the fan’s RPM and use the alert function with the Intel LANDesk Client Manager (LDCM) or the ASUS PC Probe software.

3.6.7Precautions
Operating a processor at temperatures above its maximum specified operating temperature will shorten the processor lifetime and may cause unreliable operation. To prevent system overheat and/or damage, it is important to have accurate temperature readings of the processor core (the main source of power dissipation) for system thermal management. Included inside Pentium III, Pentium II (Deschutes), FCPGA370 Celeron, and PPGA370 Celeron processors is a thermal sensor that is connected to the internal thermal diode.
Unlike other motherboards, this motherboard was designed to acquire thermal data directly from the processor thermal diode. Therefore, the CPU temperature reported may be higher than those from motherboards that take readings from thermal sensors external to the processor. This is not a cause for alarm. If, however, the BIOS and/or your hardware monitoring program is reporting a CPU temperature above the threshold, check the following:
1.An Intel recommended fan heatsink is used.
2.Good quality thermal interface material is used.
3.The heatsink is correctly installed onto the processor with a strong retention clip.
4.There is no visible gap between the processor die and heatsink.
The thermal interface material should be continuous with no through-holes or debris.

3.7Expansion Cards
WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
3.7.1 Expansion Card Installation Procedure
1.Read the documentation for your expansion card and make any necessary hardware or software settings for your expansion card, such as jumpers.
2.Remove your computer system’s cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use.
3.Carefully align the card’s connectors and press firmly.
4.Secure the card on the slot with the screw you removed above.
5.Replace the computer system’s cover.
6.Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in 4.4.3 PCI Configuration)
7.Install the necessary software drivers for your expansion card.
3.7.2 Assigning 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 will arise between the two PCI groups that will make the system unstable or cards inoperable.
