2.FEATURES

2.1.2Specifications–Optional Components

The following onboard components are optional at the time of purchase:

•Onboard Audio: AC97 V2.1 compliant Audio Codec with 3D sound circuitry and sample rate conversion from 7kHz to 48kHz.

2.1.3 Performance

•UltraPerformance: Onboard IDE Bus Master controller with two connectors that support four IDE devices in two channels. Supports UltraDMA/100, UltraDMA/ 66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices, such as DVD-ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.

•High-Speed Data Transfer Interface: IDE transfers using UltraDMA/66 Bus Master IDE can handle rates up to 66.6MB/s. This motherboard with its chipset and support for UltraDMA/100 increases the data transfer rate to 100MB/s. UltraDMA/100 is backward compatible with DMA/66, 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/66/100 requires a 40-pin 80conductor cable to be enabled.)

•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master buses to memory and processor.

•SDRAM Optimized Performance: This motherboard supports PC133-com- pliant Synchronous Dynamic Random Access Memory (SDRAM), which increases the data transfer rate to 1066MB/s max.

•ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for 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 ACPI-supported OS, such as Windows 98/2000/Millenium, must be used.

•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings

as an alternative to leaving the computer ON and QuickStart™ so that you do not have to wait for a long time for system bootup.

•New Compliancy: Both the BIOS and hardware levels of the motherboard meet the stringent requirements for PC 99 certification. The new PC 99 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 95/98/NT and later. Color-coded connectors and descriptive icons make identification easy as required by PC 99.

2.FEATURES

2.1.4Intelligence

•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 the fans are set for its normal RPM range and alarm thresholds.

•Temperature Monitoring and Alert: To prevent system overheat and system damage, this motherboard supports processor thermal sensing and auto-protection.

•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 98/ Millenium, Windows NT/2000, require much more memory and hard drive space to present enormous user interfaces and run large applications. The onboard hardware ASUS ASIC in conjunction with either the bundled ASUS PC Probe or Intel LDCM 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.

•Dual Function Power Button: Through BIOS, the power button can be defined as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see ATX Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button. Regardless of the setting, pushing the power button for more than 4 seconds will enter the Soft-Off mode.

•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 any information from their computers from anywhere in the world.

•Message LED (requires ACPI OS support): Message LEDs now act as information providers. Through the way a particular LED illuminates, the user can determine if a message has been received from a fax/modem. A simple glimpse provides useful information to the user. This function requires ACPI OS and driver support.

•Peripheral Power Up: Keyboard or Mouse power up can be enabled or disabled through BIOS setup to allow the computer to be powered ON using your keyboard or mouse click.

3.3 Hardware 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.

WARNING! Make sure that you unplug your power supply when adding or removing system components. Failure to do so may cause severe damage to your motherboard, peripherals, and/or components. The onboard LED when lit acts as a reminder that the system is in suspend or soft-off mode and not powered OFF.

3.5System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM). One side (with memory chips) of the DIMM takes up one row on the motherboard.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.

Install memory in any combination as follows:

DIMM Location	168-pin DIMM		Total Memory
Socket 1 (Rows 0&1)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
Socket 2 (Rows 2&3)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
Socket 3 (Rows 4&5)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
	Total System Memory (Max 512MB)	=

NOTE: Make sure the total installed memory does not exceeds 512MB. Otherwise, the system may hang during startup.

3.5.1 General DIMM Notes

•ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.

•BIOS shows SDRAM memory on bootup screen.

•Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64, 128, 256, 512MB.

NOTE: For PC133 SDRAM to run at 133MHz, the system CPU bus must also operate at that speed.

3.5.2Memory Installation

WARNING! Make sure that you unplug your power supply when adding or removing memory modules or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards (see 3.3 Hardware Setup Procedure for more information).

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 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.

System Memory

The notches on the DIMM will shift between left, center, or right to identify the type and also to prevent the wrong type from being inserted into the DIMM slot on the motherboard. You must tell your retailer the correct DIMM type before purchasing. This motherboard supports four clock signals per DIMM.

3.6Central Processing Unit (CPU)

The motherboard provides a ZIF Socket 370. 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! Be sure that there is sufficient air circulation across the processor’s heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary.

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 angle. Insert the CPU with the correct orientation as shown. The notched corner should point towards the end of the lever. Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown. The picture is for reference only; you should have a CPU fan that covers the face of the CPU. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, close the socket’s lever while holding down the CPU. After the CPU is , install an Intel recommended fan heatsink. Locate the CPU fan connector (see 3.1 Motherboard Layout or 3.8 Connectors) and connect the CPU fan cable to it.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for your Socket 370 processor or else boot-up may not be possible. Socket 370 processors provide internal thermal sensing so that a socket mounted thermal resistor is not needed.

CAUTION! Be careful not to scrape the motherboard when mounting a clampstyle processor fan or else damage may occur to the motherboard.

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 (see 3.3 Hardware Setup Procedure for more information).

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 PNP AND PCI SETUP)

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.

Standard Interrupt Assignments

IRQ	Priority	Standard Function
0	1	System Timer
1	2	Keyboard Controller
2	N/A	Programmable Interrupt
3*	11	Communications Port (COM2)
4*	12	Communications Port (COM1)
5*	13	Sound Card (sometimes LPT2)
