This function reduces both energy consumption and system noise, and is an
important feature in implementing silent PC systems.
•Dual Function PowerButton: Pushing the power button for less than 4 seconds
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 and system fans can be monitored for RPM and failure. All
fans are set for its normal RPM range and alarm thresholds.
•PowerLED (requiresACPIOS support):The power LEDindicates the system
status.
•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 vital information from their computers anywhere.
•Temperature Monitoring and Alert: CPU temperature is monitored by the
ASUS ASIC through the CPU’s internal thermal diode (on Pentium III and
Celeron) to prevent system overheat and system damage.
•Voltage Monitoring andAlert: 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.
•Chassis Intrusion Detection: Supports chassis-intrusion monitoring through
the ASUS ASIC. A chassis intrusion event is kept in memory on battery power
for more protection.

3.3 Hardware Setup Procedure
Complete the following steps before using your computer:
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 cables
6. Configure the BIOS parameter settings
3.4 Motherboard Settings
This section tells you how to change motherboard function settings through the
switches and/or jumpers.
3. H/W SETUP
Motherboard Settings
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To avoid damaging them due to static electricity,
follow these precautions whenever you work on your computer.
1. Unplug the computer when working on the internal components.
2. Use a grounded wrist strap or touch a safely grounded object or to a metal
object, suchas thepower supplycase, before handling computercomponents.
3. Hold components by the edges and try not to touch the IC chips on them.
4. Wheneveryou uninstall any component, placethe componentsonagrounded
antistatic pad or in the bag that came with the components.
5. Beforeyouinstallorremoveanycomponent,ensurethattheATX power
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.
(TIP:When lit, the onboard LED indicates that the system is in suspend or
soft-off mode, not powered OFF. See illustration below.)

Motherboard Frequency Settings (DIP Switches)
The motherboard frequency is adjusted through the DIP switches. The white block
represents the switch’s position. The illustration below shows all the switches in the
OFF position.
1) JumperFree™Mode (JEN)
This jumper allows you to enable or disable the JumperFree™mode. The
JumperFree™mode allows processor settings to be made through the BIOS
setup (see 4.4 Advanced Menu).
Setting JEN
Enable (JumperFree) [2-3] (default)
Disable (Jumper Mode) [1-2]
NOTE: In JumperFree™mode, set all DIP switches (DIP_SW) to OFF.

2) CPU External Frequency Selection (DIP_SW Switches 1–4)
This option tells the clock generator what frequency to send to the CPU, DRAM,
and the PCI bus. This allows the selection of the CPU’s External frequency (or
BUS Clock). The BUS Clock multiplied by the Frequency Multiple equals the
CPU’s Internal frequency (the advertised CPU speed).

3) Manual CPU Ratio Settings (DSW Switches 5-10)
Set DSW switches (5-10) to use the clock multiplier to coordinate the ratio of
bus speeds with CPU settings. Set the DSW switches according to the internal
speed of your processor and the bus frequency (133/100MHz).
IMPORTANT:
1. To use this feature, JEN must be set to Jumper Mode, [1-2].
(See 1, JumperFree™ Mode (JEN) in 3, HARDWARE SETUP.)
2. When JumperFree mode is enabled,useBIOSsetupin place of these switches.
(SetOperatingFrequency Settingto User Define under 4.4AdvancedMenu
in BIOS Setup so you can set the CPU Frequency.)
WARNING!SettheCPUfrequencyonlytotherecommendedsettings.Frequencies
other than the recommended CPU bus frequencies are not guaranteed to be stable.
Overclocking the processor is not recommended. It may result in a slower speed.

4) CPU Type Frequency Setting (PALO_FREQ)
This jumper setting accomodates the difference between the internal frequency
between standard and new AMD CPUs. If changing from one type of CPU to
another, the jumper caps must be adjusted. The factory default setting, [2-3], is
for standard Athlon/Duron CPUs. The Palomino processor will only function
on this motherboard after the jumpers are adjusted to [1-2].
