4.2 CPU Installation
This mainboard has a socket478 processor socket. Follow these instructions
to install the CPU:
1.Unhook the CPU socket’s locking lever by 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/ heatsink unit onto the CPU and CPU socket, and then

10
use the retention module clamps to snap the fan/heatsink into place.
6.Plug the CPU fan power cable into the CPU cooling fan power supply
connector on the mainboard.

4.3 Memory installation
This mainboard supports DDR200/DDR266 DDR memory ，you may install
64/128/256/512MB 184 pin DDR memory。DDR SDRAM 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 othes.
The mainboard ships with and 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
The mainboard 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 mainboard has three audio ports connect audio device.
The left side jack(green) is for a stereo line-out signal. The middle jack
(blue)is for a stereo line-in signal. The right side jack (red)is for a
microphone.
4.5.3 Clear CMOS (JP3)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You

14
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, then move the cap back to pins1-2.
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
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so BIOS can
automatically reset parameter settings to default values.
4.5.4 ATX Power connectors (20-pin ATXPWR1,4-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

15
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 ATXPWR1 and 4-pin ATX12V1 power
plugs. Failure to do so may cause severe damage to the CPU or motherboard!
