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

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, Pentium
II Deschutes, and Pentium III FC-PGA and Celeron PPGA in conjunction with
the ASUS S370-133 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.

3.5 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.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Total Memory

Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256MB x1

3.5.1 General DIMM Notes

• For the system CPU bus to operate at 100MHz, use only PC100-compliant
DIMMs. When this motherboard operates at 100MHz, most system will not

even boot if non-compliant modules are used because of the strict timing issues
involved under this speed. If your DIMMs are not PC100-compliant, set the
CPU bus frequency to 66MHz RAM to ensure system stability.

• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.

• Two possible memory chips are supported: SDRAM with and without ECC.

• SDRAM chips are generally thinner with higher pin density than EDO (Ex-

tended Data Output) chips.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,

128, 256MB.

3.5.2 Memory Installation

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.

which supports Pentium III / II and Celeron processors. There are two types of URMs:
(A) With Integrated Retainer Pins and (B) With Separate Retainer Pins.

URM (A) URM (B)

Integrated Retainer Pins

1. Place the motherboard on the anti-static foam that was shipped with the mother­board. Do not place the motherboard on a hard surface while installing the URM
as the black fastener sleeves must protrude through the bottom of the mother­board.

2. Locate the Slot 1 connector on the motherboard.

3. Position the retention mechanism on either side of the Slot 1 connector.

4. Making sure that the top retainer pins are not pushed in, press down on the
retention brackets until the black fastener sleeves fit snugly against the board.

WARNING! Installing the URM while the retainer pins are pushed in will not

only cause the URM to be installed improperly but will also damage the URM.

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)

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

3.7.2 Assigning IRQs for Expansion Cards

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.

T o see a map of your used and free IRQs in W indows 98, the Contr ol 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. 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.

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

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

PCI slot 1 -- not shared -- -­PCI slot 2 -- -- shared -­PCI slot 3 -- -- -- shared
Audio -- -- -- shared
1394 -- -- shared -­AGP slot not shared -- -- --

CPU

3. H/W SETUP

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.
