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.

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.

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.

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).

WARNING! Some pins are used for connectors or power sources. These are
clearly distinguished from jumpers in the Motherboard Layout. Placing jumper
caps over these connector pins will cause damage to your motherboard.
IMPORTANT: Ribbon cables should always be connected with the red stripe to
Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on
floppy disk drives. Check the connectors before installation because there may
be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the
second drive connector no more than 15 cm (6 in.) from the first connector.
1) PS/2 Mouse Connector (Green 6-pin PS2KBMS)
The system will direct IRQ12 to the PS/2 mouse if one is detected. If one is not
detected, expansion cards can use IRQ12. See PS/2 Mouse Function Control
in 4.4 Advanced Menu.
