2. FEATURES

2.1.4 Intelligence

• Dual Function Power Button: Pushing the power button for less than 4 sec-

onds 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.

• Message LED (requires ACPI OS support): Turbo LEDs now act as informa-

tion 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.

• Remote Ring On (requires modem): This allows a computer with this mother-

board to be turned on remotely through an internal or external modem. With this
feature, users can access their computers from anywhere in the world!

Specifications

2. FEATURES

• 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.

• 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.

3.3 Hardware Setup Procedure

Before using your computer, you must complete the following steps:

1. Check Motherboard Settings

2. Install Memory Modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

5. Connect Ribbon Cables, Panel Wires, and Power Supply

6. Setup the BIOS Software

3.4 Motherboard Settings

This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.

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.

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.

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.

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.

The following table lists the default IRQ assignments for standard PC devices. Use
this table when configuring your system and for resolving IRQ conflicts.

ASUS CUBX-L/CUBX-E User’s Manual 27

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 W indows
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 when-

3. H/W SETUP

DMA Channels

ever a PNP-compliant card is added to the system. For PNP cards, IRQs are as­signed automatically from those available.

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 4.4.3 PCI Configuration. Choose Yes in IRQ xx Used By
ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

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. To determine the BIOS version of your mother­board, check the last four numbers of the code displayed on the upper left­hand corner of your screen during bootup. Larger numbers represent a newer
BIOS file.

1. Type FORMAT A:/S at the DOS prompt to create a bootable system
floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the
disk.

2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-

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.

CPU Upgrade/Reinstallation

To ensure that your system can enter BIOS setup after the processor has
been changed or reinstalled, your system will start up running at a bus speed
of 66MHz and a fail-safe CPU speed (4x66MHz for the Intel Coppermine
processor or 2x66MHz for non-Coppermine processors). It will then auto­matically take you to the Advanced menu with a popup menu of all the

7.2 ASUS CIDB Intrusion Detection Module

The optional ASUS CIDB is a module for providing audible intrusion alarm and
logging for ASUS motherboards equipped with the chassis connector. The module
detects a chassis intrusion by either light striking its photo sensor or by the closing
or opening of a chassis-mounted momentary toggle switch. An intrusion memory
function allows detection and clearing the intrusion notification by the BIOS pro­gram on the next bootup.

7.2.1 Using the ASUS CIDB

1. You must have an ASUS motherboard with: (1) a chassis connector and (2) a
System Management Bus (SMB) connector.

2. Connect the CIDB directly to the chassis connector or use the provided exten­sion cable and mount the CIDB to the chassis using a double-sided foam adhe­sive tape or with screws and spacer posts.

CAUTION! The CIDB’s component pins and metallic points must not come in

contact with another metallic surface or else shorting will occur!

3. Use the SMBIN connector and the provided SMB cable to connect the CIDB to
the SMB connector on the motherboard. If another SMB device is already used
on the motherboard, you may unplug it and connect it to the SMBOUT connec­tor on the CIDB.

4. Check the hardware settings:

• PHOTO jumper should be enabled to use the photo sensor.

• MS1 and/or MS2 connectors should be connected to momentary toggle

switches mounted on the chassis to use the switch close or switch open
method for triggering an intrusion event.

ASUS CUBX-L/CUBX-E User’s Manual 87

5. To stop the alarm from sounding, use the BIOS setup or momentarily place a
jumper on (or short manually) the CLR jumper. Note that the jumper must be
removed for the CIDB to work normally again.

6. If you have an updated BIOS with intrusion support, booting the computer after
an intrusion may require a password if configured through BIOS.

7.2.3 ASUS CIDB Additional Considerations

1. If there is no power to the motherboard (i.e. removing the power cord or turning
the power supply’s switch off), the alarm will not sound but the CIDB will still
memorize an intrusion event which BIOS will detect on the next bootup.

2. Any chassis intrusion detection components on the motherboard will not work if
the CIDB is used.

3. The P2B-LS motherboard must use an external battery pack on the EXTBATT
connector or else neither the alarm or intrusion memory functions will work.

1394

1394 is the IEEE designation for the high performance serial bus at 12.5, 25 or
50MBytes/sec speeds. This serial bus defines both a back plane physical layer and a
point-to-point cable-connected virtual bus. The primary application of the cable ver­sion is the integration of I/O connectivity at the back panel of personal computers
using a low-cost, scalable, high-speed serial interface. The 1394 standard also pro­vides new services such as live connect/disconnect capability for external devices
including disk drives, printers and hand-held peripherals such as scanners and cam­eras. This is a new standard to complement the slower USB interface and to compete
with the more expensive SCSI interface.

AC97 (Audio Codec '97)

AC '97 is the next step in enabling PCs with audio quality comparable to consumer
electronics devices. The specification defines new cost-effective options to help in­tegrate the components necessary to support next-generation auto-intensive PC ap­plications such as DVD, 3-D multiplayer gaming and interactive music. The speci­fication also defines new extensions supporting modem and docking to help both
desktop and mobile manufacturers adopt these new technologies more quickly and
cost-effectively . This specification uses software emulation to compete with the PCI
SoundBlaster specification.

ACPI (Advanced Configuration and Power Interface)

The ACPI specification defines a cross-platform interface designed to support many
operating systems. ACPI defines a flexible and abstract hardware interface that pro­vides a standard way to integrate power management features throughout a PC sys­tem, including hardware, operating system and application software. This enables
the system to automatically turn ON and OFF peripherals such as CD-ROMs, net­work cards, hard disk drives, and printers, as well as consumer devices connected to
the PC such as VCRs, TVs, phones, and stereos. With this technology, peripherals
will also be able to activate the PC. For example, inserting a tape into a VCR can
turn on the PC, which could then activate a large-screen TV and high-fidelity sound
system.

AGP (Accelerated Graphics Port)

An interface specification that enables high-performance 3D graphics on mainstream
PCs. AGP was designed to offer the necessary bandwidth and latency to perform
texture mapping directly from system memory.

BIOS (Basic Input/Output System)

BIOS is a set of routines that affect how the computer transfers data between com­puter components, such as memory, disks, and the display adapter. The BIOS in­structions are built into the computer’s read-only memory. BIOS parameters can be
configured by the user through the BIOS Setup program. The BIOS can be updated
using the provided utility to copy a new BIOS file into the EEPROM.

Bit (Binary Digit)

Represents the smallest unit of data used by the computer . A bit can have one of two
values: 0 or 1.

ASUS CUBX-L/CUBX-E User’s Manual 89

7. APPENDIX

Glossary

7. APPENDIX

Boot

Boot means to start the computer operating system by loading it into system memory .
When the manual instructs you to “boot” your system (or computer), it means to
turn ON your computer . “Reboot” means to restart your computer . When using W in­dows 95 or later, selecting “Restart” from “Start | Shut Down...” will reboot your
computer.

Bus Master IDE

PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and
waiting for mechanical events. Bus master IDE transfers data to/from the memory
without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk
drives are required to support bus master IDE mode.

Byte (Binary Term)

One byte is a group of eight contiguous bits. A byte is used to represent a single
alphanumeric character, punctuation mark, or other symbol.

COM Port

COM is a logical device name used by to designate the computer serial ports. Point­ing devices, modems, and infrared modules can be connected to COM ports. Each
COM port is configured to use a different IRQ and address assignment.

Concurrent PCI

Concurrent PCI maximizes system performance with simultaneous CPU, PCI and
ISA bus activities. It includes multi-transaction timing, enhanced write performance,
a passive release mechanism and support for PCI 2.1 compliant delayed transac­tions. Concurrent PCI provides increased bandwidth, reduced system latencies, im­proves video and audio performance, and improves processing of host based appli­cations.

CPU (Central Processing Unit)

The CPU, sometimes called “Processor,” actually functions as the “brain” of the
computer. It interprets and executes program commands and processes data stored
in memory. Currently, there are socket 370 (for Pentium III FC-PGA and Celeron­PPGA), socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III),
slot 2 (for Xeon), and slot A (for AMD) processors.

Device Driver

A device driver is a special set of instructions that allows the computer’s operating
system to communicate with devices such as VGA, audio, printer, or modem.

DOS (Disk Operating System)

DOS is the foundation on which all other programs and software applications oper­ate, including W indows. DOS is responsible for allocating system resources such as
memory, CPU time, disk space, and access to peripheral devices. For this reason,
DOS constitutes the basic interface between you and your computer.

DRAM (Dynamic Random Access Memory)

There are several different types of DRAM such as, EDO DRAM (Extended Data
Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM).

Flash ROM

The flash ROM is designed to be a resident program and can be updated by a spe­cific programming method. Normally , the flash ROM is used for system BIOS which
initiates hardware devices and sets up necessary parameters for the OS. Since the
contents of flash ROM can be modified, users are able to update the BIOS by them­selves.

IDE (Integrated Drive Electronics)

IDE devices integrate the drive control circuitry directly on the drive itself, elimi­nating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/
100 IDE devices can achieve up to 100MB/Sec transfer.

ASUS CUBX-L/CUBX-E User’s Manual90

7. APPENDIX

LPT Port (Line Printer Port)

Logical device name reserved by DOS for the computer parallel ports. Each LPT
port is configured to use a different IRQ and address assignment.

MMX

A set of 57 new instructions based on a technique called Single Instruction, Multiple
Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium
II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX in­structions are designed to accelerate multimedia and communications applications,
such as 3D video, 3D sound, video conference.

OnNow

The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for PC that is always ON but appears
OFF and responds immediately to user or other requests. The OnNow design initia­tive involves changes that will occur in the Microsoft Windows operating system,
device drivers, hardware, and applications, and also relies on the changes defined in
the Advanced Configuration and Power Interface (ACPI) specification.

PC100

SDRAM is Intel's goal is to ensure that memory subsystems continue to support
evolving platform requirements and to assure that memory does not become a bottle­neck to system performance. It is especially important to ensure that the PC memory
roadmap evolves together with the performance roadmaps for the processors, I/O
and graphics.

PCI Bus (Peripheral Component Interconnect Local Bus)

PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard
widely used by expansion card manufacturers.

PCI Bus Master

The PCI Bus Master can perform data transfer without local CPU help and further­more, the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concur­rent PCI operation to allow the local CPU and bus master to work simultaneously.

Plug and Play BIOS

The ISA bus architecture requires the allocation of memory and I/O address, DMA
channels and interrupt levels among multiple ISA cards. However, configuration of
ISA cards is typically done with jumpers that change the decode maps for memory
and I/O space and steer the DMA and interrupt signals to different pins on the bus.
Further, system configuration files may need to be updated to reflect these changes.
Users typically resolve sharing conflicts by referring to documentation provided by
each manufacturer. For the average user, this configuration process can be unreli­able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard­ware conflict problem. The PnP BIOS uses a memory block to define and remember
each card's configuration, which allows the user to change the card's IRQs and DMA
in BIOS either automatically or manually.

POST (Power On Self Test)

When you turn ON the computer, it will first run through the POST, a series of
software-controlled diagnostic tests. The POST checks system memory , the mother ­board circuitry, the display, the keyboard, the diskette drive, and other I/O devices.

PS/2 Port

PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture
transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be
used on ATX motherboards.

Glossary

RDRAM (Rambus DRAM)

Developed by Rambus, Inc., this type of memory can deliver up to 1.6GB of data
per second. RDRAM is the first interface standard that can be directly implemented
on high performance VLSI components such as, CMOS DRAMs, memory control-

lers, and graphics/video ICs.

7. APPENDIX

ROM (Read Only Memory)

ROM is nonvolatile memory used to store permanent programs (called firmware)
used in certain computer components. Flash ROM (or EEPROM) can be repro­grammed with new programs (or BIOS).

SCSI (Small Computer System Interface)

High speed multi-threaded I/O interface defined by the X3T9.2 committee of the
American National Standards Institute (ANSI) for connecting many peripheral de­vices. The standard started from 10MBytes/sec to 160MBytes/sec available today.

SDRAM (Synchronous DRAM)

The SDRAM features a fully synchronous operation referenced to a positive edge
clock whereby all operations are synchronized at a clock input which enables the
coexistence of high performance and a simple user interface. SDRAM takes memory
access away from the CPU's control; internal registers in the chips accept the re­quest, and let the CPU do something else while the data requested is assembled for
the next time the CPU talks to the memory. As they work on their own clock cycle,
the rest of the system can be clocked faster. There is a version optimized for video
cards, and main memory for motherboards.

SPD for SDRAM module

Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using
a EEPROM component on DIMM module for storing module configuration infor­mation inside. The Serial Presence Detect function is implemented using a 2048 bit
EEPROM component. This nonvolatile storage device contains data programmed
by the DIMM manufacturer that identifies the module type and various SDRAM
organization and timing parameters.

SSE (Streaming SIMD Extensions)

A set of new instructions added to existing architectures that enables a better visual
experience with an accelerated 3D geometry pipeline and support for new applica­tions, such as real-time video encoding and speech recognition.

System Disk

A system disk contains the core file of an operating system and is used to boot up the
operating system.

UltraDMA

Ultra DMA/33 is a "synchronous DMA" protocol designed by Intel. This function is
included into Intel's PIIX4 chipset. The traditional IDE transfer only uses one edge
of the data stroke as the data transfer . Ultra DMA/33 uses both edges of data strobe
when the data is transferred. Hence, the data transfer rate is double of the PIO mode
4 or DMA mode 2 (16.6MB/s x2 = 33MB/s) on ATA-2 devices.

Ultra ATA/66, also known as Ultra DMA/66, is an extension of current Ultra ATA/
33 interface. This new high-speed interface has doubled the Ultra AT A/33 burst data
transfer rate to 66.6 Mbytes/sec and maximized disk performance under current PCI
local bus environment

USB (Universal Serial Bus)

A 4-pin serial cable bus that allows up to 127 plug and play computer peripherals
such as keyboard, mouse, joystick, scanner, printer, modem, and monitor to share a
bandwidth through a host scheduled token based protocol. This allows attaching or
detaching while the host and other peripherals are in operation. Supports synchro­nous and asynchronous transfer types over the same set of wires up to 12Mbit/sec.
USB 2.0 provides twice the transfer rate compared to USB 1.0 and competes with
the 1394 standard.

Wake-On-LAN

Computer will automatically wake-up upon receiving a wake-up packet through a
Network interface when it is under power soft-off, suspend or sleep mode.
