System Installation Setup
Before using your computer, you must finish the following steps: 1. Set jumpers on mainboard 2. Install SDRAM module. 3. Install the Processor. 4. Connect Ribbon Cables, Cabinet Wires, and Power supply. 5. Install Add on Cards. 6. Setup the BIOS software.
Static Electricity Precaution
Keep the mainboard and other system components in their antistatic packaging until you are ready to install them. Do all preparative work on a static-free surface with the main board components facing up. Unplug your computer when working on the inside. Wear an Anti-static wrist strap. Hold the system components, boards or cards by its edges only. Be careful not to touch any of IC chips, circuitry, contacts or connections, especially gold contacts on the mainboard.
10 / Chapter 3 Installation
Jumper Settings
Jumpers Several hardware setting are made through the use of jumper caps to connect jumper pins (Jxx) on the mainboard. See " Map of the mainboard" for the locationed the jumpers. The jumper settings will be described numerically such as [----], [1-2], [2-3] for no connection, connect pins 1 & 2, and connect pins 2 & 3 respectively. Pin 1 for our mainboard is always on top one or on the left when holding the mainboard with the keyboard away from yourself. "P1" is written besides pin 1 on jumper with three pins. The jumpers will also be shown graphically such as to connect pin 1&2 and to connect 2&3. Jumpers with two pins will be shown as for Short (on )and for Open (off).For manufacturing simplicity it may be sharing pins from other groups. Use the diagrams in this manual instead of following the pin layout on the board. Settings with two jumper numbers require that both jumpers be moved together. To connect the pin, simply place a plastic jumper cap over the two pins as diagrammed.

Real Time Clock (RTC) RAM - JBAT1 : The CMOS RAM is powered by the onboard button cell battery. To clear the RTC data: (1)Turn off your computer, (2) Move this jumper to "2-3Pin Clear Data", (3) Move the jumper back to "Default", (4) Turn on your computer, (5) Hold down during bootup and enter BIOS setup to re-enter user Preferences.

System Memory ( DIMM Module)
This 5VIA73 main board supports three 168 pins DIMM of 16 MB, 32 MB, 64 MB, 128 MB ,256MB to form a memory size between 16MB to 256MB. The DRAM can be either 45ns,50ns,or 60ns 3.3v SDRAM,and 3.3v Enhanced Data Output (EDO) RAM. Install memory in any or all Banks in Combination: Bank DIMM 1 ( Bank 0-1 ) DIMM 2 ( Bank 2-3 ) DIMM 3 ( Bank 4-5 ) Memory module 16MB,32MB,64MB,128MB,128MB 168 pin,3.3v SDRAM / EDO RAM 16MB,32MB,64MB,128MB,256MB 168 pin 3.3v,SDRAM / EDO RAM 16MB,32MB,64MB,128MB,256MB 168 pin 3.3v,SDRAM / EDO RAM Total System Memory(Max 640 MB)
Note :
The DIMM Slot does not support any 5v EDO DIMM module. The DIMM Slot does not support any 5v SDRAM DIMM module. Memory speed setup is required through "Auto Configuration" in BIOS chipset Setup of BIOS SOFTWARE. If several speed memorious are used, You must set Auto Configuration to low. Example If both 50ns, 60ns are used, Please set Auto configuration to 60ns. It's allowed any DIMM module put in any DIMM slot. It's allowed there are different capacity DIMM module in all DIMM slot.

DIMM Memory Installation
Insert the module (s) as shown. Because the number pins are different on either side of the breaks,the module will only fit in the orientation as shown. SDRAM DIMM modules have different pin contacts on each side and therefore have a higher pin density.

CPU Installation
The motherboard provides a ZIF socket 7. The CPU that came with the motherboard should have a fan attached to it to prevent overheating . If this is not the case then purchase a fan before you turn on your system. 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 correct orientation shown . The notched corner should point towards the end of the lever. Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown.

Clearance Requirements
To maintain proper airflow once the processor is installed on the mainboard, the processor and fan heatsink require certain space clearances. The clearance above the processor must be at least 0.3 inch. The clearance on at least 3 of 4 sides of the processor and fan heatsink must be at least 0.2 inch. All cables (for Floppy drive,Hard drive,CD-ROM,and so on) must be routed clear of the processor and its airspace.
Fan Exhaust
The processor must be kept cool by using a processor with heatsink an fan attached . The temperature of the air filled with the fan/heatsink cannot exceed 45 OC(113 OF ) . The ambient or room temperature must be below 37 OC ( 99 OF) .

7. FAN1 , FAN2 CPU Cooling Fan (JFAN1,2) These connectors support cooling fans of 500mAmp (6Watt) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan's plug to the board taking into consideration the polarity of this connector.

8. Primary / Secondary IDE connectors (Two 40-pin Blocks) These connectors support the provided IDE hard disk ribbon cable. After connecting the single end to the board, connect the two plugs at the other end to your hard disk no space(s) . If you install two hard disks, you must configure the second drive to Slave mode by setting its jumper settings. BIOS now supports SCSI device or IDE CD-ROM boot up (see "HDD Sequence SCSI/ IDE First" & "Boot Sequence" in the BIOS Features Setup of the BIOS SOFTWARE) (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 20 plugged).
Tip :
You may configure two hard disks to be both Masters using one ribbon cable on the primary IDE connector. You may install one operating system on an IDE drive and another on a SCSI drive and select right one the through BIOS Feature Setup. 9. IrDA / Fast IR-Compliant infrared module connector - JIR1 This connector supports the optional wireless transmitting and receiving infrared module. This module mounts to a small opening on system cases that support this feature. You must also configure the setting through UART2 Use Infrared" in Chipset Feature Setup to select whether UART2 is directed for use with COM2 or IrDA. Use the five pins as shown on the Back View and connect a ribbon cable from the module to the motherboard according to the pin definitions.

a. IDE activity LED (HD-LED) This connector supplies power to the cabinet's IDE activity LED. Read and write activity by devices connected to the Primary or Secondary IDE connectors will cause the LED to light up. b. Power LED Lead (PE_BN) The system power LED lights when the system's power is on. c. SMI Suspend Switch Lead (SMI) This allows the user to manually place the system into a suspend mode or "Green" mode where systematic activity will be instantly decreased to save electricity and expand the life of certain components when the system is not in use. This 2-pin connector (see the figure below) connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the "Turbo Switch" since it does not have a function. SMI is activated when it detects a short to open moment and therefore leaving it shorted will not cause any problems. It may require one or two pushes depending on the position of the switch. Wake-up can be controlled by settings in the BIOS but the keyboard will always allow wake-up (the SMI lead cannot wake-up the system). If you want to use this connector,"Suspend Switch" in the Power Management Setup of the BIOS SOFTWARE section should be on the default setting of Enable d. Reset Switch Lead (RST) This 2-pin connector connects to the case-mounted reset switch for rebooting your computer without having to turn off your power switch. This is a preferred method of rebooting in order to prolong the life of the system's power supply.

e. System Power LED (PANEL) The system power LED lights when the system's power is on (same as above Power LED). 11. ATX/AT Power Supply Connector (pin block) - CN2/CN3 This connector connects to a ATX power supply. The plug from the power supply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned.
IMPORTANT:
Make sure that the ATX power supply can take at least 10mAmp load on the 5Volt standby lead (5VSB). You may experience difficulty in powering on your system without this.
