sis panel open events into LDCM. The onboard battery supports detection even when normal power is removed and through a new design, battery drain is even lower than the RTC used for keeping time!

• PC Health Monitoring: Provides an easy way to examine and manage system

status information, such as CPU and systerm voltages, temperatures, and fan status through the onboard hardware ASUS ASIC and the bundled ASUS PC Probe or Intel LDCM software.

• PCI/ISA Expansion Slots: Provides five 32-bit PCI (Rev. 2.2) expansion slots,

which can support Bus Master PCI cards, such as SCSI or LAN cards, and one ISA slot (optional) to support legacy add-on cards. (PCI supports up to 133MB/s maximum throughput.) In LAN models, supports a secondary Wake-On-LAN activity with an optional Wake-On-LAN Ethernet card on the expansion slot.

• Enhanced ACPI & Anti-Boot Virus Protection: Programmable BIOS (Flash

EEPROM), offering enhanced ACPI for W indows 98 compatibility , built-in firmware-based virus protection, and autodetection of most devices for virtually automatic setup.

• Smart BIOS: 4Mb firmware gives a new easy-to-use interface which provides

more control and protection over the motherboard. Provides Vcore and CPU/ RDRAM frequency adjustments, boot block write protection, and HD/SCSI/MO/ ZIP/CD/Floppy boot selection. Hardware random number generator supports new security software for data protection and secured Internet transactions.

• SMBus: Features the System Management Bus interface, which is used to physi-

cally transport commands and information between SMBus devices.

2. FEATURES

Optional Components

2.1.2 Specifications–Optional Components

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

• Network Interface: Features the Intel 82559 Fast-Ethernet Controller (fully inte-

grated 10BASE-T/100BASE-TX) with Alert-On-LAN and W ake-On-LAN Support.

• Adaptec SCSI Chipset: Features Adaptec’s Ultra160 SCSI controller—AIC-

7892B SCSI chipset—that supports any combination of 50-pin narrow or 68pin Wide/LVD devices through the optional onboard 50- and 68-pin SCSI connectors. Ultra160 SCSI technology provides new levels of I/O performance (160MB/sec compared with Ultra2 SCSI’s 80MB/sec) and reliability. Besides, it is completely backward compatible with every generation of SCSI devices.

• PCI Audio: Provides Yamaha PCI audio chipset.

• Infrared Interface: Integrated serial infrared interface supports an optional re-

mote control package for wireless interfacing with external peripherals, personal gadgets, or an optional remote controller.

• Wake-Up/Alert Support: Supports Wake-On-LAN/-On-Ring and Alert-On-

LAN activity.

2. FEATURES

Performance

2. FEATURES

2.1.3 Performance

• UltraPerformance: Onboard IDE Bus Master controller with two connectors that

support four IDE devices in two channels. Supports 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 T ape Backup drives.

• Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz.

• 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.)

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory to CPU.

• RDRAM Optimized Performance: This motherboard supports the new gen-

eration memory , Rambus Dynamic Random Access Memory (RDRAM). While PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s, Rambus DRAMs can operate at up to 800MHz with a peak bandwidth of 1.6GB/s.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality . W ith 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.

• 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 fall asleep waiting for system bootup.

• New Compliancy: Both the BIOS and hardware levels of the motherboard meet

PC 99 compliancy. 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 W indows 95/98/ NT. Color-coded connectors and descriptive icons make identification easy as required by PC 99.

2. FEATURES

2.1.4 Intelligence

• 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: T oday’s operating systems such as Windows 98, W in-

dows 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.

• 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 25) A TX Power / Soft-Off Switch Lead in 3.8 External 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 infor- mation providers. Through the way a particular LED illuminates, the user can determine if there are messages waiting in the email inbox. A simple glimpse provides useful information to the user.

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

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard 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

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.

3.5 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory. This motherboard has two Rambus Inline Memory Module (RIMM) sockets. These

sockets (see Important notes for details) support Direct RDRAMs (both ECC and non-ECC are supported) in 64, 96, 128, 192, 256, and 512MB densities for a maximum of 1GB.

With the optional ASUS DR2 DIMM Riser, unbuffered Synchronous Dynamic Random Access Memory (SDRAM, 3.3V power level) in 64, 128 , 256, or 512MB densities with Serial Presence Detect (SPD) can also be used on the second socket for a maximum of 1GB.

The chipset’s Error Checking and Correction (ECC) feature is available only when using RDRAMs. ECC feature is not available when using SDRAM with an ASUS DIMM Riser (ECC memory modules may still be used, but the ECC function will not be available).

3.6.7 Precautions

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:

3. H/W SETUP

3. HARDWARE SETUP

CPU

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.

3.7 Expansion 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 PNP and PCI Setup under IV. BIOS SETUP)

7. Install the necessary software drivers for your expansion card.

3. HARDWARE SETUP

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.

*These IRQs are usually available for ISA or PCI devices.

DMA Channels

3. H/W SETUP

Both ISA and PCI expansion cards may require IRQs. System IRQs are available to cards installed in the ISA expansion bus first, then any remaining IRQs are available to PCI cards. Currently, there are two types of ISA cards.

The original ISA expansion card design, now referred to as legacy ISA cards, requires that you configure the card’s jumpers manually and then install it in any available slot on the ISA bus. To see a map of your used and free IRQs in Windows 98, the Control Panel icon in My Computer, contains a System icon, which gives you a Device Manager tab. Double-clicking on a specific hardware device gives you the Resources tab which shows the Interrupt number and address. Double-click Computer to see all the interrupts and addresses for your system. Make sure that no two devices use the same IRQ or your computer will experience problems when those two devices are in use at the same time.

To simplify this process, this motherboard complies with the Plug and Play (PNP) specification which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.

ASUS P3C-L / P3C-S / P3C-LS User’s Manual 39

3. H/W SETUP

Connectors

3. HARDWARE SETUP

If the system has both legacy and PNP ISA cards installed, IRQs are assigned to PNP cards from those not used by legacy cards. The PCI and PNP configuration of the BIOS setup utility can be used to indicate which IRQs are being used by legacy cards. For older legacy cards that do not work with the BIOS, you can contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those used by legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to PCI cards that require an IRQ. To install a PCI card, you need to set the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an INTA #, be sure that the jumpers on your PCI cards are set to INT A.

Assigning DMA Channels for ISA Cards

Some ISA cards, both legacy and PNP , may also need to use a DMA (Direct Memory Access) channel. DMA assignments for this motherboard are handled the same way as the IRQ assignment process described earlier. You can select a DMA channel in the PCI and PNP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy

ISA cards (see PNP and PCI Setup under IV. BIOS SETUP . Choose Yes in IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

3.7.3 Accelerated Graphics Port (AGP)

SCSI Connection and Termination Information

Each SCSI channel is like a water hose where the inside must be opened and the ends must be closed. Each connector, whether 68 pins or 50 pins may have single or double-ended configurations. For Single-Ended configurations, the Termination for that particular channel must be set to Enabled in 4.4.3 PCI Configuration. For Double-ended configurations, the Termination for that particular channel must be set to Disabled in 4.4.3 PCI Configuration. Each channel may have up to 15 devices (ID#0-15, with #7 reserved for the chipset).

The onboard Adaptec AIC-7892B chipset (optional) incorporates an advanced multimode I/O cell that supports both single-ended (SE) and low voltage differential (LVD) devices. With Ultra160 devices, the SCSI bus platform performs at full Ultra160 speeds (up to 80 MB/sec in 8-bit mode and up to 160 MB/sec in 16-bit mode) and extended cabling 12m (or 25m in a point-to-point configuration). When an SE device is attached, the bus defaults to an SE speed and cable length.

In mixed environments of L VD and SE devices, the onboard host adapter can be coupled with the Adaptec AIC-3860Q transceiver chipset (optional) to bridge the compatibility gap. By dividing the SCSI bus into independent SE and low voltage differential (LVD) segments, the transceiver chipset supports legacy devices without limiting performance and cable length on the LVD segment.

4.1 Managing and Updating Your BIOS

4.1.1 Upon First Use of the Computer System

It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later . AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode.

4.2 BIOS Setup Program

This motherboard supports a programmable EEPROM that can be updated using the provided utility as described in 4.1 Managing and Updating Your BIOS.

The utility is used if you are installing a motherboard, reconfiguring your system, or prompted to “Run Setup”. This section describes how to configure your system using this utility.

Even if you are not prompted to use the Setup program, at some time in the future you may want to change the configuration of your computer. For example, you may want to enable the Security Password Feature or make changes to the power management settings. It will then be necessary to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the EEPROM.

The EEPROM on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. This appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup utility . If you are a little bit late in pressing the mentioned key, POST will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing the Reset button on the system chassis. You can also restart by turning the system OFF and then back ON again. But do so only if the first two methods fail.

The Setup program has been designed to make it as easy to use as possible. It is a menu-driven program, which means you can scroll through the various sub-menus and make your selections among the predetermined choices.

To access the BIOS Setup program, press the <Delete> key after the computer has run through its POST.

NOTE: Because the BIOS software is constantly being updated, the following BIOS screens and descriptions are for reference purposes only and may not reflect your BIOS screens exactly.

This field determines when to activate the video OFF feature for monitor power management. Configuration options: [Always On] [Suspend -> Off]

Video Off Method [DPMS OFF]

This field defines the video OFF features. The DPMS (Display Power Management System) feature allows the BIOS to control the video display card if it supports the DPMS feature. [Blank Screen] only blanks the screen (use this for monitors without power management or “green” features. If set up in your system, your screen saver will not display with [Blank Screen] selected). [V/ H SYNC+Blank] blanks the screen and turns OFF vertical and horizontal scanning. Configuration options: [Blank Screen] [V/H SYNC+Blank] [DPMS Standby] [DPMS Suspend] [DPMS OFF] [DPMS Reduce ON]

HDD Power Down [Disabled]

Shuts down any IDE hard disk drives in the system after a period of inactivity as set in this user-configurable field. This feature does not affect SCSI hard drives. Configuration options: [Disabled] [1 Min] [2 Min] [3 Min]...[15 Min]

Suspend-to-RAM Capability [Disabled]

Suspend-to-RAM (STR) is an energy-saving feature. In Suspend-to-RAM state, all devices on the computer are turned OFF, except for the system RAM. Thus, the PC consumes less than 5 Watts of power. [Auto] allows the BIOS to detect if your power supply can supply at least 720mA on the +5VSB lead to support the STR function. If the power supply meets the requirement, the STR function will be enabled; if not, this function will be disabled. If the expansion cards you use on the motherboard do not support the STR function, you must leave this field on the default setting [Disabled]. Configuration options: [Auto] [Disabled]

Suspend Mode [Disabled]

Sets the time period before the system goes into suspend mode. Configuration options: [Disabled] [1~2 Min] [2~3 Min] [4~5 Min]...[1 Hour]

PWR Button < 4 Secs [Soft off]

When set to [Soft off], the ATX switch can be used as a normal system power-OFF button when pressed for less than 4 seconds. [Suspend] allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode. Regardless of the setting, holding the ATX switch for more than 4 seconds will power OFF the system. Configuration options: [Soft off] [Suspend]
