4.2 CPU Installation
This main board has a socket 478 processor socket. Follow these instructions to install
the CPU:
1. Unhook the CPU socket’s locking lever pulling it away from socket and raising it to
the upright position.
2. Match the pin 1 corner of CPU socket to the one of processor, and insert the processor
into the socket. Do not use force.
3. Push the locking lever down and hook it under the latch on the edge of socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU fan/heat sink unit onto the CPU and CPU socket, and then use the
retention module clamps to snap the fan/heat sink into place.
6. Plug the CPU fan power cable into the CPU cooling fan power supply connector on the
main board.

4.3 Memory installation
This main board supports DDR200/DDR266 DDR memory you may install
64/128/256/512MB 184 pin DDR memory. DDR SDROM uses additional power and
ground lines and requires 184-pin 2.5V unbuffered DIMM module rather than the 168-
pin 3.3V unbuffered DIMM used by SDRAM.
Follow these instructions to install the Memory:
1. Push the latches on each side of the DIMM slot down.
2. Align the memory module with the slot. The DIMM slots are keyed with notches and
the DIMMS are keyed with cutouts so that they can only be installed correctly.
3. Check that the cutouts on the DIMM module edge connector match the notches in the
DIMM slot.
4. Install the DIMM module into the slot and press it firmly down until it seats correctly.
The slot latches are levered upwards and latch on to the edges of the DIMM.
5. Install any remaining DIMM modules.
4.4 IDE Devices Installation
IDE devices include hard disk drives, high-density diskette drives, and CD-ROM or
DVD-ROM drives, among others.
The main board ships with an IDE cable that can support one or two IDE devices. If you
connect two devices to a single cable, you must configure one of the drives as Master and
one of the drives as Slave. The documentation of the IDE device will tell you how to
configure the device as a Master or Slave device. The Master device connects to the end
of the cable.

4.5 Other Device Installation
4.5.1 Floppy Disk Drive Installation
This main board ships with a floppy disk drive cable that can support one or two drives.
Drives can be 3.5” or 5.25” wide, with capacities of 360K, 720K, 1.2MB, 1.44MB, or
2.88MB.
Install your drives and connect power from the system power supply. Use the cable
provided to connect the drives to the floppy disk drive connector floppy.
4.5.2 Sound Connector Port Installation
This main board has three audio ports connects audio device.
The left side jack (green) is for a stereo line-out signal. The middle jack (gray) is for a
stereo line-in signal. The right side jack (red) is for a microphone.
4.5.3 Wake on LAN (WOL)
If you have installed a LAN card, use the cable provided with the card to plug into the
main board WOL connector. This enables the Wake on LAN feature. When you system is
in a power saving mode, any LAN signal automatically resumes the system. You must
enable this item using the power Management page of the Setup Utility.
4.5.4 Clear CMOS (JP3)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time, and system setup parameters by erasing the
CMOS RTC RAM data. The RAM data in CMOS, that include system setup information
such as system passwords, is powered by the onboard button cell battery.
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pin 1-2(default) to pin 2-3. Keep the cap on pin 2-3 for
about 5-10 seconds, and then move the cap back to pinsl-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <DEL> key during the boot process and enter BIOS setup to re-enter
data.
Note1: Except when clearing RTC RAM, never remove the cap on CLRTC1 jumper
default position. Removing the cap will cause system boot failure!
Note2: You do not need to clear the RTC when the system hangs due to over
clocking. For system failure due to over clocking, use the C.P.R. (CPU Parameter
Recall) feature. Shut down and reboot the system so BIOS can automatically reset
parameter settings to defaults values.
4.5.5 ATX Power connectors (20-pin ATXPWRI, 4-pin ATX 12V1)

These connectors connect to an ATX 12V power supply. The plugs from the power
supply are designed to fit these connectors in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit. In addition to the
20-pin ATXPWR1 connector, connect the 4-pin ATX +12v power plug to provide
sufficient power to the CPU.
Note1: Make sure that you ATX 12V power supply can provide at least 15A on the
+12V lead and at least 2A on the +5-volt standby lead (+5VSB). The minimum
recommended wattage is 300W or above for a fully configured system. The system
may become unstable and may experience difficulty powering up if the power
supply is inadequate.
Note2: Do not forget to connect the 20-pin ATXPWRI and 4-pin ATX12V1power
plugs. Failure to do so may cause severe damage to the CPU or motherboard!
