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 which 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 all of the socket IC’s to make sure that they are properly inserted. Do this only
on with the board placed on a firm flat surface.
War i g: Do ot apply power to the board if it has bee 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- Installation Steps
Before using your computer, you must follow the steps as follows:
1. Set Jumpers on the Motherboard
2. Install the CPU
3. Install DRAM Modules
. Install Expansion card
5. Connect Cables, Wires, and Power Supply
2-5 Jumper Settings
1. CPU Bus Frequency : This motherboard auto-detected the processor speed. You only
need insert the MD thlon processor into Slot.
2. CMOS RAM Clear: JBAT (Yellow color selector)
WARNING: Make sure your computer is POWER OFF whe you CLEAR CMOS.
Connect a jumper Cap over this jumper for a few seconds, will clears information stored in
the CMOS RAM Chip that input by user, such as hard disk information and passwords.
After CLEAR CMOS, you must enter the BIOS setup (by holding down <DEL> during
power-up) to re-enter BIOS information (see BIOS SETUP).

2-7-1 The motherboard provides a Slot A for AMD® Athlon™ processor. The CPU on board
must have a fan or heat sink attached to prevent overheating.
WARNING: Without a fa or heat si k, the CPU will overheat a d cause damage to both the CPU
a d the motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the Slot1 and place
RETENTION MODULE as following:
1. Attach heat sink to the CPU.
2. Place Part A on slot-1 and gently screw four corners on top of the mother- board.
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.
. 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 .
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 motherboard 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.

AWARD BIOS SETUP
This mainboard has previously set to its best stable status. If you are not an experienced user,
please do not change the default setting. When you are encounter any problem, please choice
“LOAD STANDARD DEFAULTS” to restore best setting.
Award’s ROM BIOS provides a built-in Setup program which allows user modify the basic
system configuration and hardware parameters. The modified data will be stored in a battery-
backed CMOS RAM so data will be retained even when the power is turned off. In general, the
information saved in the CMOS RAM stay unchanged unless here is configuration change in
the system, such as hard drive replacement or new equipment is installed.
It is possible that CMOS had a battery failure which cause data lose in CMOS_RAM. If so, re-
enter system configuration parameters become necessary.
To enter Setup Program
Power on the computer and press <Del> key immediately will bring you into BIOS CMOS
SETUP UTILITY.

This section allows you to configure the system based on the specific features of the installed chipset.
This chipset manages bus speeds and access to system memory resources, such as DRAM and the
external cache. It also coordinates communications between the conventional ISA bus and the PCI bus.
It must be stated that these items should never need to be altered. The default settings have been chosen
because they provide the best operating conditions for your system. The only time you might consider
making any changes would be if you discovered that data was being lost while using your system.
