an interface to support very affordable multichannel audio, V.90 analog modem, Home PNA, 10/100 Ethernet networking, USB hub, as well as future technologies such as xDSL.

• PCI Expansion Slots: Provides three 32-bit PCI (PCI 2.2 compliant) expansion

slots. All PCI slots can support Bus Master PCI cards, such as SCSI or LAN cards. (PCI supports up to 133MB/s maximum throughput.)

• Low Pin Count (LPC) Multi-I/O: Provides two high-speed UAR T compatible

serial ports and one parallel port with EPP and ECP capabilities. UART2 can also be directed from COM2 to the Infrared Module for wireless connections.

• 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: 4Mbit firmware gives a new easy-to-use interface which provides

more control and protection over the motherboard. Provides Vcore and CPU/ SDRAM 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.

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

ter busses to the memory and processor.

• Onboard LED: The onboard LED will light up when there is standby power to

the motherboard. This acts as a reminder to the user to turn OFF the power before plugging and unplugging devices so as not to damage the motherboard, peripherals, and/or components.

2.1.2 Specifications–Optional Components

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

• Smart Networking: Features 3Com’s 3C920 Fast Ethernet controller, which

supports Wired for Management, remote wake-up, and OnNow initiatives to reduce Total Cost of Ownership (TCO).

2.1.3 Performance

2. FEATURES

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/R W , LS-120, and T ape 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 mas-

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

ASUS CUSL2-M User’s Manual

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.

• T emperature Monitoring and Alert: T o prevent system overheat and system dam-

age, 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, Win-

dows NT , and OS/2, 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 infor- mation 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.

Intelligence

2. FEATURES

• 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.

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

3.4 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.

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.

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.

3.6 Central 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. W ithout 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 clamp-

style processor fan or else damage may occur to the motherboard.

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 (see 3.3 Hardware Setup Proce-

dure 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 moth-

erboard 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) 6 14 Floppy Disk Controller 7* 15 Printer Port (LPT1) 8 3 System CMOS/Real Time Clock 9* 4 ACPI Mode when enabled 10* 5 IRQ Holder for PCI Steering 11* 6 IRQ Holder for PCI Steering 12* 7 PS/2 Compatible Mouse Port 13 8 Numeric Data Processor 14* 9 Primary IDE Channel 15* 10 Secondary IDE Channel
