Hardware Setup 2-1
Chapter 2. Hardware Setup
Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or
disconnect the power cord before installing or unplugging any connectors or add-on cards. Failing to do
so may cause the motherboard components or add-on cards to malfunction or damaged.
2-1. Install The Motherboard
Most computer chassis have a base with many mounting holes to allow motherboard to be securely
attached on and at the same time, prevented from short circuits. There are two ways to attach the
motherboard to the chassis base:
1. use with studs
2. or use with spacers
In principle, the best way to attach the board is to
use with studs. Only if you are unable to do this
should you attach the board with spacers. Line up
the holes on the board with the mounting holes on
the chassis. If the holes line up and there are
screw holes, you can attach the board with studs.
If the holes line up and there are only slots, you
can only attach with spacers. Take the tip of the
spacers and insert them into the slots. After doing
this to all the slots, you can slide the board into
position aligned with slots. After the board has been positioned, check to make sure everything is OK
before putting the chassis back on.
ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they
are already fastened on the chassis base and are without mounting-holes on the motherboard to align with.
2-2. Install CPU and Heatsink
Note
• Installing a heatsink and cooling fan is necessary for heat to dissipate from your processor.
Failing to install these items may result in overheating and processor damage.
• The AMD Socket A processor will produce a lot of heat while operating, so you need to use a
large heat sink that is especially designed for the AMD socket A processor. Otherwise, it may
result in overheating and processor damage.
• If your processor fan and its power cable are not installed properly, never plug the ATX power
cable into the motherboard. This can prevent possible processor damage.
• Please refer to your processor installation manual or other documentation with your processor for
detailed installation instructions.
User’s Manual
2-2 Chapter 2
This motherboard provides a ZIF (Zero Insertion
Force) Socket 462 to install AMD Socket A CPU.
The CPU you bought should have a kit of
heatsink and cooling fan along with. If that’s not
the case, buy one specially designed for Socket A.
Please refer to the figure shown here to install
CPU and heatsink. (For reference only. Your
Heatsink & Fan Assembly may not be exactly the
same as this one.)
1. Locate the Socket 462 on this motherboard.
Pull the CPU release lever sideways to
unlatch and then raise it all the way up.
2. Align the CPU notch to the socket notch for
CPU. Drop the processor with its pin side
down into the CPU socket. Do not use extra
force to insert CPU; it only fit in one
direction. Close the CPU release lever.
3. Remove the plastic film adhesive on the
heatsink. Make sure the stepped portion of
the heatsink is facing toward the end of the
socket that reads “Socket 462”. Put the
heatsink faces down onto the processor until
it covers the processor completely.
4. Push down the short end of the retaining clip
first to lock up with the center lug at the
bottom of the socket.
5. Use a screwdriver to insert into the slot at the
long end of the retaining clip. Push the clip
downward to lock up with the center lug at
the top of the socket. The heatsink & fan
assembly is now firmly attached on the CPU
socket.
6. Attach the fan connector of Heatsink & Fan
Assembly with the fan connector on the
motherboard.
ATTENTION: Do not forget to set the correct
bus frequency and multiple for your processor.

Hardware Setup 2-3
2-3. Install System Memory
This motherboard provides four 184-pin DDR DIMM slots for Dual Channel DDR 266/333/400 memory
modules with memory expansion size up to 4GB.
To reach the performance of Dual Channel DDR, the following rules must be obeyed:
• When installing TWO DIMM modules: Install DIMM modules of the same type and size for
slots [DIMM1]+[DIMM3] or slots [DIMM2]+[DIMM4].
• When installing FOUR DIMM modules: Install DIMM modules of the same type and size for
slots [DIMM1]+[DIMM3], and slots [DIMM2]+[DIMM4].
Bank Memory Module Total Memory
Bank 0, 1 (DIMM1) 256MB, 512MB, 1GB 256MB ~ 1GB
Bank 2, 3 (DIMM2) 256MB, 512MB, 1GB 256MB ~ 1GB
Bank 4, 5 (DIMM3) 256MB, 512MB, 1GB 256MB ~ 1GB
Bank 6, 7 (DIMM4) 256MB, 512MB, 1GB 256MB ~ 1GB
Total System Memory 256MB ~ 4GB
NOTE: Usually there is no hardware or BIOS setup require after adding or removing memory modules,
but you will have to clear the CMOS memory first if any memory module related problem occurs.
User’s Manual
2-4 Chapter 2
Power off the computer and unplug the AC power cord before installing or removing memory modules.
1. Locate the DIMM slot on the board.
2. Hold two edges of the DIMM module
carefully, keep away of touching its
connectors.
3. Align the notch key on the module with the
rib on the slot.
4. Firmly press the module into the slots until
the ejector tabs at both sides of the slot
automatically snaps into the mounting notch.
Do not force the DIMM module in with extra
force as the DIMM module only fit in one direction.
5. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and
then pull out the DIMM module.
ATTENTION: Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a
grounded metal object briefly.

(12). Floppy and IDE Disk Drive Connectors
The FDC1 connector connects up to two floppy drives with a 34-wire, 2-connector floppy cable. Connect
the single end at the longer length of ribbon cable to the FDC1 on the board, the two connectors on the
other end to the floppy disk drives connector. Generally you need only one floppy disk drive in your
system.
NOTE: The red line on the ribbon cable must be aligned with pin-1 on both the FDC1 port and the floppy
connector.
Each of the IDE port connects up to two IDE drives at
Ultra ATA/100 mode by one 40-pin, 80-conductor, and
3-connector Ultra ATA/66 ribbon cables.
Connect the single end (blue connector) at the longer
length of ribbon cable to the IDE port of this board, the
other two ends (gray and black connector) at the shorter
length of the ribbon cable to the connectors of your hard
drives.
NOTE: Make sure to configure the “Master” and “Slave” relation before connecting two drives by one
single ribbon cable. The red line on the ribbon cable must be aligned with pin-1 on both the IDE port and
the hard-drive connector.
