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 4.6 Power Management Setup). 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 the stage the computer is in. 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.

• Temperature Monitoring and Alert: CPU temperature is monitored by the

ASUS ASIC through the CPU’s internal thermal diode (on Pentium III, Deschutes
Pentium II, and PPGA370 Celeron in conjunction with the ASUS S370-D or
S370-L CPU card) to prevent system overheat and system damage.

• 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.

3.4 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. T o 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.

Motherboard Features Settings (DIP Switches - DIP_SW)

The motherboard’s onboard functions are adjusted through the DIP switches. The
white block represents the switch’s position. The example below shows all the

3.5 System 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 Ac-
cess Memory (SDRAM). One side (with memory chips) of the DIMM takes up one
row on the motherboard.

To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and make
the proper settings through 4.5 Chipset Features Setup.

Memory speed setup is recommended through SDRAM Configuration in 4.5 Chipset
Features Setup.

3.6.5 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), 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)

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

3.7.2 Assigning IRQs for Expansion Cards

IMPORTANT: Interrupt requests are shared as shown by the following table:

INT-A INT-B INT-C INT-D

PCI slot 1 -- -- -- -­PCI slot 2 -- -- shared -­PCI slot 3 -- -- -- shared
Audio -- -- -- shared
1394 -- -- shared -­AGPslot -- -- -- --

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.

Some expansion cards need to use 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 extra IRQ will be used, leaving 5 IRQs
free. If your motherboard has ISA audio onboard, an extra 3 IRQs will be used,
leaving 3 IRQs free.

3. H/W SETUP

Expansion Cards

Both ISA and PCI expansion cards may require the use 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 an 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

ASUS P3B-1394 User’s Manual 27

Manager tab. Double-clicking on a specific hardware device gives you the Re-

sources tab which shows the Interrupt number and address. 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.

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

3. H/W SETUP

DMA Channels

something called 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.

3. HARDWARE SETUP

3.7.3 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 4.7 PNP and PCI Setup, choose Yes in IRQ xx Used By ISA and DMA
x Used By ISA for those IRQs and DMAs you want to reserve).

3.7.4 Accelerated Graphics Port (AGP)

This motherboard provides an accelerated graphics port (AGP) slot to support a new
generation of graphics cards with ultra-high memory bandwidth, such as an ASUS
3D Hardware Accelerator.

3.8 External Connectors

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 connectors 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 (6-pin PS2KBMS)

The system will direct IRQ12 to the PS/2 mouse if one is detected. If not de­tected, expansion cards can use IRQ12. See PS/2 Mouse Function Control in
