2.5.2 DIMM Memory Installation
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. DIMM mod-
ules are longer and have different pin contact on each side and therefore have a
higher pin density. DIMM modules have the same pin contact on both sides.

thelever gently sideways away from the socket.
Then lift the lever upwards. The socket lever
must be fully opened (90 to 100 degrees).
2. Insert the CPU with the correct orientation.The
notched corner of the CPU must be oriented
toward the inner corner of the socket base
nearest to the lever hinge.
CAUTION! The CPU fits in one orientation
and should drop easily into place. Donotforce
the CPU into the socket to avoid bending the
pins. If the CPU does not fit, check its
alignment and look for bent pins.
3.Once completely inserted,press the CPUfirmly
and close the socket lever until it snaps into its locked position.
4. Place the CPU fan and heatsink on the CPU. The heatsink should entirely cover
the CPU. Carefully attach the heatsink locking brace to the plastic clips on the
socket base. With the added weight of the CPU fan and heatsink locking brace,
no extra force is required to keep the CPU in place.
2.6 Central Processing Unit (CPU)
The motherboard provides a Socket 462 or SocketAfor CPU installation.Afan and
heatsink should be attached to the CPU to prevent overheating. Purchase and install
a fan and heatsink before turning on the system.
CAUTION! Take care not to scrape the motherboard surface when mounting a
clamp-style processor fan, or else damage may occur. Ensure that exposed CPU
capacitors do not touch the heatsink, or else damage may occur!
NOTE! Do not forget to set the correct Bus Frequency and Multiple (available
only on unlocked processors) to avoid start-up problems.

2.7 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.
2.7.1 PCI Expansion Card Installation Procedure
1. Read the documentation for your expansion card and make any necessary hard-
ware 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
7. Install the necessary software drivers for your expansion card.
2.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu-
sively 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 additional IRQ will be used. If your moth-
erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

2.8 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 connector pins 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 connec-
tor 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 one is not
detected, expansion cards can use IRQ12. See PS/2 Mouse Function Control
in 4.4 Advanced Menu.
