1-1 Preface

Thank you for purchasing this multifunction motherboard. It has the mos t flexibility you can find in today’s computer market. The mainboard integrates both Intel Pentium®II / Pentium®III & Celeron™(Slot 1) / Coppermine processor and Celeron™ (Socket 370) PPGA / FCPGA processor interface into a compact PC/ATX compatible system along with next generation of 4 X AGP specification, 133MHz FSB, Ultra DMA66, and optional 3D Stereo Sound System audio chip. Moreover, this mainboard allows you conditionally approach 140MHz* of Front Side Bus Frequency to accelerate your CPU speed.

1-2 Feature of motherboard

This motherboard is design for the PC user who wants highest possible quality and value in a small package. It includes following main features：

1-2-1 Overv i ew

• Support both Slot 1 & Socket 370 CPU interface (You can only use one CPU interface

at a time).

Hardware Installation

2-1 Unpacking

This mainboard package should contain the following:

• The mainboard

• USER’S MANUAL for mainboard

• Cable set for Ultra DMA 66 IDE x1, Floppy x1

• CD for Drivers PACK

The mainboard contains sensitive electronic components that can be easily damaged by electron-static, so the mainboard should be left in its original packing until it is installed.

Unpacking and installation should be done on a grounded anti-static mat. The operator should be wearing an anti static wristband, grounded at the same point as the anti-

static mat. Inspect the mainboard carton for obvious damage. Shipping and handling may cause damage to

you r bo a r d . Be s u r e th e r e are no sh i p p i n g a nd handling damages on the board before proceeding. After opening the mainboard carton, extract the system board and place it only on a grounded

anti-static surface component side up. Again inspect the board for damage. Press down on the entire socket IC’s to make sure that they are properly inserted. Do this only

on with the board placed on a firm flat surface.

Warning: Do not apply power to the board if it has been damaged.

You are now ready to install your mainboard. The mounting hole pattern on the mainboard matches the ATX system board.

It is assumed that the chassis is designed for a standard ATX main board mounting. Place the chassis on the anti-static mat and remove the cover.

Take the plastic clips, Nylon stand-off and screws for mounting the system board, and keep them separate.

2-7 Central Processing Unit (CPU)

2-7-1 The mainboard provides a Slot-1 for Pentium II/III processor. The CPU on board must

have a fan or heat sink attached to prevent overheating.

WARNING: Without a fan or heat sink, the CPU will overheat and cause damage to both the CPU

and the mainboard.

To install a CPU, first turn off your system and remove its cover. Locate the Slot- 1 and place RETENTION MODULE as following:

IMPORTANT: You must set jumper U19, U20 for “Bus Frequency Selection” and “CPU Ratio” on

page6 depending on the CPU that you install.

1. Attach heat sink to the CPU.

2. Place Part A on Slot-1 and gently screw four corners on top of the main- board.

PART A

2-7-2 The mainboard also provides a 370-pin ZIF Socket 370. The CPU on mainboard must

have a fan attached to prevent overheating. To install a CPU, first turn off your system and remove its cover. Locate the ZIF Socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree

right angle. Insert the CPU with the white dot as your guide. The white dot should point towards the end of the level. The CPU has a corner pin for three of the four corners, the CPU will only fit in the one orientation as shown as follow. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, hold down on the fan and close the Socket’s lever.

CPU Insertion

Step 1

Open the socket by raising the actuation lever.

Step 2

Insert the processor. Ensure proper pin 1 orientation by aligning the FC-PGA corner marking with the socket corner closest to the actuation arm tip. The pin field is keyed to prevent misoriented insertion.

Don’t force processor into socket. If it does not go in easily, check for mis-orientation and debris.

Make sure the processor is fully inserted into the sock et on all sides.

Step 3

Close the socket by lowering and locking the actuation lever.

Step 1

Remove the protective liner from the thermal interface material on the underside of the heatsink.

This liner is not normally present on the Intel reference active heatsink.

Step 2

Orient the heatsink with the keyed edge of heatsink along the cam box side of the processor.

The clip should be oriented so that the thumb tab will engage on the cam box side of the socket.

Step 3

Seat the heatsink onto the processor and engage the clip opposite from the cam box onto

2-8 Expansion Cards

You must read the documentation come with expansion card for any hardware or software settings that may be required to setup your specific card.

Installation Procedure:

1. Read the documentation from your expansion card.

2. Set any necessary jumpers on your expansion card.

3. Remove your computer’s cover.

4. Remove the bracket on the slot you intend to use.

5. Carefully align the card’s connectors and press firmly.

6. Secure the card on the slot with the screw you remove in step 4.

7. Replace the computer’s cover.

8. Setup the BIOS if necessary.

9. Install the necessary software drivers for your expansion card.

Assigning IRQs for Expansion Cards

Some expansion cards may require an IRQ to operate. Generally an IRQ must be exclusively assigned to only one device. In an standard design there are 16 IRQs available but most of

them are occupied by the system and leaves 6 free for expansion cards. With most recent device, the BIOS automatically assign an IRQ number to PCI expansion cards.

Please make sure there are no any of two devices use same IRQs, otherwise your computer may experience some problems when those two devices are in use at the same time.

Assigning DMA Channels for Expansion Cards

Some devices may also need to use a DMA (Direct Memory Access) channel. DMA assignments for this mainboard are handled the same way as the IRQ assignment process described above. You can select a DMA channel in the PCI and PnP configuration section of the BIOS Setup utility.

2-9 External Connectors

1. Power Connector: ATX Power Connector (20-pin block): PL1

ATX Power Supply connector. This is a new defined 20-pins connector that usually comes with ATX case. The ATX Power Supply allows to use soft power on momentary switch that connect from the front panel switch to 2-pins Power On jumper pole on the mainboard. When the power switch on the back of the ATX power supply turned on, the full power will not come into the system board until the front panel switch is mom entarily pressed. Press this switch again will turn off the power to the system board.
