2.1.1 Jumper Settings
In this manual , (1-2) represents the first and second pins of the jumper. (2-3) represents the second and
third pins of the jumper. On the motherboard, you will see two sets of jumpers with different color jumper
caps:
Yellow Jumper Caps: Sets the Function of Flash CMOS
JRTC
Green Jumper Caps: Sets the type and speed of CPU
JF0, JF1, JF2, JF3
Red Jumper Caps : Sets the FSB frequency of CPU
JFSB0, JFSB1
WARNING: Electronic parts are Static sensitive. To prevent damage to the computer and its parts please take
the following measures.
Work on a surface such as concrete, linoleum or hard wood floor.
Ground your self with either a properly installed grounding strap or by touching a major electrical
appliance long enough to discharge the static.
2.1.2 Clearing the CMOS(Yellow Jumper Caps)
JRTC : CMOS Function Selection
1-2:Clear data
2-3:Normal Operation(Default Setting)
How to Clear the CMOS Setting
1. Turn off the power.
2. Remove ATX power cable from connector ATXPWR.
3. Remove Yellow Jumper Cap from JRTC(2-3)and put on JRTC(1-2)to remove the CMOS setting.
4. Remove Yellow Jumper Cap from JRTC(1-2)and put on JRTC(2-3).
5. Connect ATX power cable back to connector ATXPWR.
6. Turn on the power.
7. While the system reboots, press <DEL> key to set the BIOS setup.
2.1.3 CPU Voltage Setting
The motherboard supports CPU VID function. It can automatically detect CPU VID signal and generates proper
CPU core voltage.

The Ratio of some latest CPUs are fixed by Intel and VIA such as Celeron/Celeron II/Pentium III 366, 400,566…
etc and VIA Cyrix III CPU. You can ignore the four jumpers if you have this CPU on board and it will be auto
detected by motherboard. Please check with the CPU manufacturer or vendor for the CPU Ratio information.
2.1.5 CPU FSB Frequency Setting
The JFSB jumper provides some FSB frequency settings for the CPU. Auto Detect , 66MHz, 100MHz or
133MHz FSB frequency can be selected with this jumper. The over specification operation is not recommended.
2.2 Installation of CPU
2.2.1 For Celeron, Pentium II & III CPU
The motherboard provides a Single Edge Contact(SEC)slot for processor packaged in an SEC cartridge. Follow
these steps to install CPU:
Mount the Universal Retention Mechanism (URM) & Insert the CPU: ( The illustration is just for reference )

This URM was designed to accommodate 3 types of CPU Form Factor. ( SECC, SECCII & SEPP ). For
example : Pentium II, Pentium III & Celeron family.
Note : Please put a soft pad under M/B before the installation of URM.
Installation for SECC CPU :
1. Leave space below each mounting hole for the fastener to protrude through the hole.
2. Position URM on the M/B next to the slot1 connector.
3. Push down retainer pin into respective fastener to secure URM onto the M/B.
4. Push CPU into URM to contact with slot1.
5. Make sure latching portion of CPU engaged with windows ledge of URM.
Installation for SECC II or SEPP CPU :
1. Same as step (1) of SECC.
2. Same as step (2) of SECC.
3. Same as step (3) of SECC.
4. Same as step (4) of SECC.
5. Snap in 2 clips into side windows of URM to secure SEPP CPU.
If there is a fan on the CPU, Please plug in the fan cable to the three pin fan connector on the motherboard
(FAN1).
2.2.2 For Socket 370 CPU
Before installing CPU, make sure the power is off. Locate the level bar on the PGA370 ZIF socket. Push level
bar away from the socket and pull upward 90 degrees. Insert the CPU into the socket. Make sure the notch of
the CPU corresponds with the white dot on the ZIF socket (the corner without pin socket). Do not push in the
CPU. Make sure all pins are aligned with the CPU socket. ON the level bar.
2.3 Installation of Memory
The motherboard has 3x168-pin 64-bit Dual Inline Memory Module (DIMM) sockets divided into 3 banks. You
can install 3.3V Unbuffered PC100/133 compliant Synchronous DRAM(SDRAM)memory. This will increase the
system reliability.
2.3.1 Installation of 168-pin DIMM (Dual Inline Memory Module)
1. Before inserting the DIMM, make sure the pin1 of the DIMM matches with the pin1 on the DIMM socket.
2. Insert DIMM into the DIMM sockets at a 90-degree angle and press down.
2.3.2 Removal of 168-pin DIMM
1. Press the holding clips on both sides of the socket outward to release the DIMM.

2. Gently pull the DIMM out of the socket.
2.3.3 Memory Configuration
There is no jumper setting required for the memory size or type. It is automatically detected by the system BIOS, and
the total memory size is to add them together.
DIMM Socket DIMM Modules
DIMM1 PC100/133 SDRAM 8, 16, 32, 64, 128, 256, 512MB
