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 anti-
static 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.

Chapter 3 Installation / 9
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. Set-
tings 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.

System Memory ( DIMM Module)
This 6VIA89 main board supports three 168 pins DIMM of 16
MB, 32 MB, 64 MB, 128 MB ,256MB to form a memory size be-
tween 16MB to 256MB.
The DRAM can be either Intel PC133-compliant SDRAMs.
Install memory in any or all Banks in Combination:
Bank Memory module
DIMM 1 16MB,32MB,64MB,128MB,256MB
( Bank 0-1 ) 168 pin,3.3v SDRAM / EDO RAM
DIMM 2 16MB,32MB,64MB,128MB,256MB
( Bank 2-3 ) 168 pin 3.3v,SDRAM / EDO RAM
DIMM 2 16MB,32MB,64MB,128MB,256MB
( Bank 2-3 ) 168 pin 3.3v,SDRAM / EDO RAM
Total System Memory(Max 768MB)
Note :


At the time this user's manual was written, 256MB
DIMM's are only available as double-sided registered
memory (128Mbit cells).


The motherboard operates at 133MHz, therefore
PC133-compliant modules must be used because of the
strict timing issues involved under this speed.

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

Chapter 3 Installation / 13
The Dual Inline Memory Module (DIMM) memory module must
be 3.3v Extended Data Output (EDO) DRAM or SDRAM. You can
identify the type of DIMM module by the illustration below:
168 Pin DRAM DIMM Notch Key Definitions
The notch on the DIMM module will shift between left, center, or
right to identify the type and also to prevent the wrong type to be
inserted into the DIMM slot on the Mainboard. You must ask your
retailer for Specifications before purchasing.

CPU Installation
The motherboard provides a ZIF socket 370. The CPU that came with
the motherboard should have a fan attached to it to prevent over-
heating . 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
and 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) .

1. PS/2 AT Keyboard port
This connection is for a standard keyboard using an PS/2 plug
(mini DIN) . This connector will not allow standard at AT size
(large DIN) keyboard plugs. You may use a DIN to mini DIN adapter
on standard AT keyboards.
2. PS/2 Mouse port
This system will direct IRQ12 to PS/2 mouse.
3. Serial Port COM 1 and COM 2 port
The COM1/2 serial ports can be used for pointing devices or
other serial devices. See "Onboard Serial Port" in chipset Feature
Setup of the BIOS SOFTWARE.
NOTE:
Serial {D-type 9pin (F) } must be connected to the
serial port.
4. Parallel Printer port
You can enable the parallel port and choose the IRQ through "
Onboard Parallel Port" in Chipset. Feature Setup of the BIOS
SOFTWARE.
5. Universal Serial BUS Ports 1 & 2
Two USB ports are available for connecting USB devices.
6. Floppy drive connector
This connector supports the provided floppy drive ribbon cable.
After connecting the single end to the board, connect the two
plus on the other end to the floppy drives.
7. FAN1 , FAN2 CPU Cooling Fan (FAN1,2)
These connectors support cooling fans of 500mAmp
(6Watt) or less. Orientate the fans so that the heatsink fins
allow airflow to go across the onboard heat sink(s) instead
of the expansion slots. Depending on the fan manufacturer,
