1-3 Notice of Hardware Installation Before hardware installation, make sure you have checked the following things. A. Check the package If any of these items is missing or damaged, contact the dealer from whom you purchase. Leave this main board in its original package until you are ready to install it. In the package, there are: This motherboard 1 Manual...
2-3 Jumper Setting There is no Hardward jumper setting when install CPU, meanwhile user needs to set correct “CPU clock ration” under “Frequency/ Voltage Control” in the BIOS, e.g. the ratio for 1.5G CPU is “x15”, 20G CPU is “x20” …(Please refer to page 58).
2-3-2 JP3: Keyboard Wake Up Function JP3 is a 3-pin selector that provides keyboard wake up function. Set “1-2” to disable and set “2-3” to enable keyboard wake up function. Jp3: Keyboard Wake Up Function Selector JP 3 Set "1-2" Normal (default) Set "2-3"...
2-4 CPU Installation The first step in the installation of your CPU is the insertion of the CPU into the 478 pins CPU socket. Please follow the steps as outlined below carefully to avoid damage to the CPU. Avoid Static Electricity The Intel P4 processors and your motherboard contain sensitive electronic components that can be easily damaged by static electricity.

It should take no force to install the processor, this is a zero insertion force (ZIF) socket. If it takes any force you are doing something wrong. Check the pin alignment and also make sure the release lever is raised up completely. After placing the CPU lower the release lever to lock the processor in place.

The following picture shows a side view of the heatsink with the retaining clip at the bottom of the heatsink. Make sure this retaining clip is at the bottom of the heatsink before trying to install it. The following picture shows the non-moveable end of the heatsink retaining clip installed on the lug at the bottom of the processor socket.
2-4-1 CPU and System Cooling Any attempt to operate the Intel P4 Processor without a suitable cooling solution will result in permanent damage to the processor and potentially other components within the system. FAN Headers Your motherboard allows the use of in all 3 FANs. Of these 3 FANs, 1 can be used by the CPU Heatsink assembly.
2-5 Connectors There are many connectors on this main board. Refer to the following pages for details. 2-5-1 Front Panel Front panel has connectors as “SPEAKER,” “RESET,” “HDD_LED,” “SUSLED,” “PWR_LED,” “SOFT-PWR.” Please refer the details as below. PWR_LED HDD_LED SPEAKER RESET SUSLED SOFT_PWR...
Page 20
SPEAKER is a 4-pin keyed Berg strip. This speaker connector is for the internal case speaker. This speaker will enable the BIOS to give spoken messages in case of boot up trouble. The BIOS been codes also use this speaker. For Games and Music this speaker will not be used, but rather the back panel line-out connector.
2-5-2 Back Panel Connectors There are PS/2 keyboard/ mouse, USB, COM1/2, LPT1, MIC, LINE-IN, LINE-OUT and GAME Port on case back panel. Please refer to more details as below.
Page 22
COM1/COM2 The onboard serial port 1 and port 2 are the 9-pin D-subminiature male connector COM1 and COM2. COM1 and COM2 can be disabled in BIOS setup. Please refer to Chapter 3 “Integrated Peripherals” for more information. PS2 Keyboard/ Mouse The Keyboard can be plugged in in only one way.
2-5-3 Power Supply Connector This main board needs P4 power supply which contains ATX, AUX_1 & AUX_PW1 3 power connectors, ATX power supply connector has 20 pins, which is especially designed for ATX case. AUX_1 power supply connector has 4 pins. The ATX power supply supports the function of the “Soft Power On Momentary switch”...
been guaranteed for proper function. 2-5-4 Floppy Disk Connector Floppy Disk Connector has 34 pins and allows connection of a floppy drive. In all two floppy drives can be connected to the mother board, known as floppy A and B. The BIOS allows you to disable the floppy controller if you do not use any floppy driver, that will free an Interrupt.
2-5-5 IDE1 and IDE2 The IDE connectors are used to connect IDE devices such as Harddisks and CD- ROM drives to the motherboard. Each connector constitutes an IDE channel, each channel accepts 2 IDE devices, one Master and one Slave. The IDE 1 connector is also known as the primary channel, IDE 2 is the secondary channel.
2-5-6 Internal Audio Connectors Internal Audio Connectors are “CD_IN.” It is a CD ROM external audio input signal to line-out (speaker) of the main board. CD_IN...
2-5-7 WOL1: Wake up on LAN (Optional) Wake up on LAN marked as “WOL1,” is a 3-pin connector. To support this feature, a network card is required for the system and network management software must be installed, too. WOL1 WOL1 (Wake up on LAN) function requirement: Power supply should be able to offer at least 1A current driving ability to the signal “5V trickle voltage.”...
2-6 Memory This motherboard supports only Dual Inline Memory Modules (DIMMs). Two sockets are available for 3.3 Volt unbuttered SDRAM (Synchronous Dynamic Random Access Memory). The sizes that are supported are:8, 16, 32, 64, 128, or 256 , memory sizes between 64MB to 512MB can be formed this way. Refer to the picture below for the position of the DIMM slots: Memory speed is controlled through the BIOS, on the Advanced Chipset Features Setup page.
WARNING: DIMM modules that have more than 18 chips are not supported on this STOP motherboard. (Due to signal integrity) If the system CPU bus operates at 100MHz/133MHz, use only PC100- /PC133-compliant DIMMs. (System won’t boot otherwise) 2-6-1 Memory Installation The DIMM modules can be inserted in DIMM slots 1 to 2.
Chapter3 Software Install 3-1 Notice of CD Driver Installation This CD contains below drivers. The user must read “Index” before installing required drivers. Index offers all the information on all the drivers. CD driver is always updated with the latest version, so the actual CD content may be somewhat different from the above picture.
Chapter4 The BIOS The BIOS is a piece of software (Basic Input Output System) that performs most low level tasks. When you start up your system, the BIOS is the first code that gets to run. The BIOS resides in a FLASH ROM, and the code in the FLASH ROM can be updated through a special utility called AWDFLASH.
For the latest official BIOS revision, please go to our website at www.lucky-star.com.tw. On the support page you can find the latest BIOS files for our motherboards. Updating the BIOS As said, this procedure is complicated, only update your BIOS when you experience problems with your system.
Go into the Frequency/Voltage Control page to adjust your CPU speed and voltage (please make sure the CPU voltage matches your CPU specs, in case of doubts leave it to ‘default’). Save your settings and you are done. The CMOS memory The BIOS uses the CMOS memory to store all the settings that have been made through the BIOS Setup pages.
Normally JP6 will be in the 1-2 position, this will connect the battery to the southbridge of the chipset which contains the CMOS memory. If JP6 is temporarily set to 2-3 this will interrupt the battery electricity flow, and the CMOS memory will be erased, this will however only work if the power supply is not switched on.
All items that start with a are submenus. Pressing [enter] when a submenu is selected will enter that submenu. Modifying selected items The [Up]/[Down] keys can be used to modify values within the selected fields. Note that some fields also let you enter values directly. Hot Keys Throughout the BIOS Setup Pages the hot keys will give you access to a group of commands.
