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, Com1 & Com2 x 1,PS/2 Mouse x1, LPT x1,
Audio & Game x 1(for motherboard come with Audio Chip)
•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
your board. Be sure there are no shipping and 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 AT system board.
It is assumed that the chassis is designed for a standard AT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.

CLEAR CMOS, you must enter the BIOS setup (by holding down <DEL> during power-up) to re-
enter BIOS information (see BIOS SETUP).

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 JP9 for “Bus Frequency Selection” 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

8
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.

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.
