Intelligent Features (some features require the optional hardware/thermal monitor)
• Auto Fan Off: The system fans will power off automatically even in sleep
mode.This function reduces both energy consumption and system noise, and is
an important feature in implementing silent PC systems.
• DualFunctionPowerButton(requiresATXpowersupply):Pushingthepower
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 setting (see Power Management Setup under BIOS 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 fan and system fans can be monitored for RPM and failure.
All the fans are set for its normal RPM range and alarm thresholds.
• Keyboard Power Up: Keyboard Power Up can be enabled or disabled to allow
the computer to be powered ON using your keyboard.
• Message LED (requiresACPI OS support):Turbo LEDs now act as informa-
tion providers. Through the way a particular LED illuminates, the user can de-
termine the stage the computer is in.Asimple glimpse provides useful informa-
tion to the user.
• Remote Ring On (requires external modem): This allows a computer to be
turned on remotely through an external modem. With this benefit on-hand, any
usercan access vitalinformationfrom theircomputerfrom anywhere intheworld!
• 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 enor-
mous 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: To prevent system overheat and system
damage, there are thermal sensors to monitor the CPU (the Pentium II processor
requires a special heatsink with a thermal sensor) and system temperatures to
warn of damaging temperatures.
•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.

1. Motherboard Settings
This section explains how to change your motherboard’s functions 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 electric-
ity, 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.
Jumpers
III. H/W SETUP
1. Keyboard Power Up (KBPWR)
This allows you to enable or disable the keyboard power up function. Set to
Enable if you want to use your keyboard (by pressing the SPACEBAR) to power
up your system. This feature requires an ATX power supply that can supply at
least 300mA on the +5VSB lead and new BIOS support. The default is set to
Disablebecause not all computers have the appropriateATX power supply.Your
computer will not function if you set this to Enable but do not have the appropri-
ate ATX power supply.

2. System Memory (DIMM)
NOTE: No hardware or BIOS setup is required aftrer 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) of either 8, 16, 32, 64, or 128MB. 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 “Chipset Features Setup” in BIOS setup.
Memoryspeed setupis recommended throughSDRAM Configurationunder“Chipset
Features Setup” in BIOS setup.
General DIMM Notes
•Forthesystem CPU bus tooperateabove 100MHz, use onlyPC100-compli-
ant DIMMs . This motherboard operates at 100MHz, thus most systems 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 for system 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.
• 4 or 8 chips/side modules do not support ECC, only 5 or 9 chips/side modules
support ECC.
• Single-sided DIMMs come in 4, 8, 16, 32, 64,128MB; double-sided come in 8,
16, 32, 64, 128, 256MB.
Install memory in any combination as follows:
DIMM Location 168-pin DIMM Memory Modules Total Memory
Socket 1 (Rows 0&1) SDRAM 4, 8, 16, 32, 64, 128, 256MB x1
Socket 2 (Rows 2&3) SDRAM 4, 8, 16, 32, 64, 128, 256MB x1
Socket 3 (Rows 4&5) SDRAM 4, 8, 16, 32, 64, 128, 256MB x1

DIMM Memory Installation Procedures:
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 as 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.

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,
check the notches on the DIMMs (see figure below).

The notches on the DIMM will shift between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM.
