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 JRTC1
Green Jumper
Caps: Sets the type and speed of CPU JF0, JF1,
JF2
Red Jumper Cap: Sets the FSB frequency of CPU JFSB
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]
JRTC1: 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 J3.
3. Remove Yellow Jumper Cap from JRTC1(2-3)and put on JRTC1(1-2)to remove the CMOS setting.
4. Remove Yellow Jumper Cap from JRTC1(1-2)and put on JRTC1(2-3).
5. Connect ATX power cable back to connector J3.
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 Pentium II VID function, the CPU core voltage is automatically detected, the
range is from 1.3V to 3.5V.

550/100 366/66 5.5x 2-3 2-3 2-3
The Ratio of some latest CPUs are fixed by Intel, such as Celeron 366,400...etc. You can ignore the three
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 three FSB frequency settings for the CPU. Auto Detect , 66MHz or 100MHz or
133MHz FSB frequency can be selected with this jumper. The 100MHz FSB frequency setting is over
specification operation for 66MHz FSB CPU. The over specification operation is not recommended.
2.2 Installation of CPU
The motherboard provides a Single Edge Contact(SEC)slot for a Pentium II processor packaged in an SEC
cartridge. Follow these steps to install Pentium II CPU:
Mount the Universal Retention Mechanism (URM) & Insert the Pentium II 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 CPU, please plug in the fan cable to the three pin fan connector on the motherboard (
CPUFAN ).
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 Extended Data Output (EDO)or Unbuffered 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 EDO/SDRAM 8, 16, 32, 64, 128, 256MB
DIMM2 EDO/SDRAM 8, 16, 32, 64, 128, 256MB

This connector supports the optional wireless transmitting and receiving infrared module, with this
module and application software such as Laplink or Win95 Direct Cable Connection, user can
transfer files to or from their laptops, notebooks, PDA, PCs and printers. The connector supports
IrDA (115.2Kbps, 2 meters) and ASK-IR (56Kbps). Install infrared module onto Infrared connector
and configure the setting through 'UART Mode Select' in Integrated Peripherals to select whether
UART is directed for use with COM2 or Infrared.
2.4.4 Wake-up on LAN Connector (3-pin JP1)
The JP1 connector powers up the system when a wakeup packet or signal is received from the
network . This feature requires the Wake up on LAN function in BIOS is set to Enabled and that your
system has an ATX power supply with at least 720mA +5V standby power.
2.4.5 Floppy Disk Drive Connector (34-pin JFLP1)
This connector supports the provided floppy disk drive ribbon cable. Orient the red stripe to pin 1
2.4.6 Primary/Secondary IDE Connector (Two 40-pin IDE)
These connectors support the provided IDE hard disk ribbon cable. Connect your first IDE hard disk
to master mode of the primary channel. If you have second IDE device to install in your system,
