HARDWARE INSTALLATION
Central Processing Unit: CPU
The mainboard operates with AMD®DuronTM/Athlonprocessor. The
mainboard uses a CPU socket called Socket 462 for easy CPU installation.
The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.
3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

The mainboard CPU Bus Frequency can be set through BIOS setup.
If CPUClock = 100MHz
Core/Bus ratio = 7
then CPU core speed = HostClockx Core/Bus ratio
= 700MHz

•Fan Power Connectors: C_FAN1/S_FAN1
These connectors support system cooling fan with + 12V. It supports
three pin head connector. When connecting the wire to the connec-
tor, always take note that the red wire is the positive and should be
connected to the +12V, the black wire is Ground and should be
connected to GND. If your mainboard has System Hardware Monitor
chipset on-board, you must use a specially designed fan with speed
sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: 1. Always consult vendor for proper CPU cooling fan.
2. CPU FAN supports the FAN control. You can install PC Alert
utility. This will automatically control the CPU FAN Speed according
to the actual CPU temperature.

Clear CMOS Jumper: JBAT1
A battery must be used to retain the mainboard configuration in CMOS
RAM. Short 1-2 pins of JBAT1 to store the CMOS data.

Note: You can clear CMOS by shorting 2-3 pin, while the system is off.
Then, return to 1-2 pin position. Avoid clearing the CMOS while
the system is on, it will damage the mainboard. Always unplug
the power cord from the wall socket.

Memory Installation
•Memory Bank Configuration
The mainboard supports a maximum memory size of 1.5 GB. It provides
three 168-pin unbufferedDIMMs (Double In-Line Memory Module) sockets.
It supports 8 MB to 512 Mbytes DIMM memory module.
DIMM1(Bank0+Bank1)
DIMM2(Bank2+Bank3)
DIMM3(Bank4+Bank5)
There are three kinds of DIMM specification supported
by this mainboard: PC133, PC100 and PC66. If you
use 66MHz CPU Bus Frequency, these three DIMM
Specs. is supported. If you use 100 MHz CPU Bus
Frequency, PC100 and PC133 DIMM Specs. is sup-
ported. If you use 133MHz CPU Bus Frequency, only
PC133 DIMM Specs. will be supported
!

A. HowtoinstallaDIMMModule
1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.

1. Supports only SDRAM DIMM.
2. To operate properly, at least one 168-pin DIMM module must be in-
stalled.
3. This mainboard supports Table Free memory, so memory can be installed
on DIMM 1 or DIMM 2 or DIMM 3 in any order.
4. Supports 3.3 volt DIMM.
5. The DRAM addressing and the size supported by the mainboard is
shown below:

Power Switch
Connect to a 2-pin push button switch.
Reset Switch
Reset switch is used to reboot the system rather than turning the power ON/
OFF. Avoid rebooting while the HDD LED is lit. You can connect the Reset
switch from the system case to this pin.
Power LED
The Power LED is lit while the system power is on. Connect the Power LED
from the system case to this pin. There are two types of LED that you can
use: 3-pin single color LED or 2-pin dual color LED (ACPI request).
a. 3 pin single color LED connect to pin 4, 5, & 6. This LED will lit
when the system is on.
b. 2 pin dual color LED connect to pin 5 & 6.
GREENColor: Indicate the system is in full on mode.
ORANGEColor: Indicate the system is in suspend mode.
Speaker
Speaker from the system case is connected to this pin.
HDD LED
HDD LED shows the activity of a hard disk drive. Avoid turning the power
off while the HDD led is lit. You can connect the HDD LED from the system
case to this pin.
