remotely through an internal or external modem. With this benefit on-hand, users
can access vital information from their computers anywhere.

Intelligence

2. FEATURES

• System Resources Alert: Today’s operating systems such as Windows 95/98/

2000/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
warns the user before the system resources are used up to prevent possible
application crashes. Suggestions provide the user some 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.

3.5.2 Memory Installation

WARNING! Make sure that you unplug the power supply when adding or

removing memory modules or other system components. Failure to do so may
cause severe damage to both the motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).

Insert the module(s) into the DIMM sockets as shown. Because the number of pins
are different on either side of the breaks, the module only fits in one direction. SDRAM
DIMMs have different pin contacts on each side and have a higher pin density than
DRAM SIMMs.

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

System Memory

The notches on the DIMM shifts 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.

Note in the illustration that CPUs have marks (usually a notch or a gold mark on one
corner) to help you identify the proper orientation and enable you to correctly install
a CPU. It is important that you match the marked corner of the CPU with the
corresponding corner on the socket so as not to damage the CPU pins.

The CPU picture above is for reference only. Usually, when you buy a CPU, the
heatsink and fan are already attached to the CPU. If a heatsink and fan did not come
with the package, make sure you obtain one before installing the CPU.

WARNING! You must install the proper heatsink and fan to the CPU. Failure to

do so will cause the CPU to overheat and may damage both the CPU and the
motherboard. Install an auxillary fan, if necessary.

CAUTION! Be careful not to scrape the motherboard when mounting/unmounting

a clamp-style processor fan to avoid damaging the motherboard.

Proceed to the next section for the steps on how to properly install a CPU.

3.6.1 CPU Installation

Follow these steps to install a CPU.

1. Locate the ZIP socket on the motherboard.

2. Unlock the socket by pressing the lever sideways then lifting it up to a 90°-100°
angle.

3. Position the CPU above the socket such that its notched or marked corner matches
the socket corner near the end of the lever, while making sure that the CPU is
parallel to the socket.

4. Carefuly insert the CPU into the socket until it fits in place.

CAUTION! The CPU fits only in one orientation. Do not force the CPU into the

socket to prevent bending the pins and damaging the CPU. If the CPU does not
fit completely, check its orientation or check for bent pins.

5. Secure the CPU into the socket by pushing the socket lever all the way down.
You will hear a click indicating that the lever is in place.

6. Attach the heatsink and fan to the CPU, if they were not pre-installed by the
vendor . Refer to the installation instructions that came with the heatsink and fan.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for the processor to avoid
start-up problems.

3.7 Expansion Cards

In the future, you may need to install expansion cards. The motherboard has one PCI
riser card slot to support a PCI card. Follow the steps in the next section when
installing an expansion card.

WARNING! Unplug the system power cord when adding or removing expansion

cards or other system components. Failure to do so may cause severe damage to
both the motherboard and the expansion card.

3.7.1 Installing an Expansion Card

1. Read the documentation that comes with the expansion card and make any
necessary hardware settings for the card before installing it.

3. H/W SETUP

2. Remove the system unit cover and the bracket plate on the slot you intend to use.
Keep the screw for later use.

3. Detach the riser card from the PCI card slot on the motherboard.

4. Carefully insert the golden fingers of the expansion card into the connector on
the riser card.

5. Insert the golden fingers of the riser card to the PCI slot on the motherboard
until it fits in place.

6. Secure the card to the slot with the screw you removed earlier.

7. Replace the system cover.

8. Change the necessary BIOS settings, if any.
(see section 4.4.3 PCI Configuration to change the settings.)

9. Install the necessary software drivers for the expansion card.

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 the motherboard
has PCI audio onboard, an additional IRQ will be used. If the motherboard also has
MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

The following table lists the default IRQ assignments for standard PC devices. Use
this table when configuring your system and for resolving IRQ conflicts.

Standard Interrupt Assignments

IRQ Priority Standard Function

0 1 System Timer
1 2 Keyboard Controller
