Step 1

®

Install the CPU:

1. Locate the CPU ZIF (Zero Insertion Force) socket on the upper-right
sector of your mainboard (between the back-panel connectors and the

DIMM memory slots).

2. Pull the CPU ZIF socket lever slightly sideways away from the socket
to unlock the lever, and then bring it to an upward vertical position.

3. Place your PPGA / FC-PGA 370 processor in the ZIF socket. Note that
the CPUs edges have been purposely designed non-symmetrical to

prevent from inserting the processor in wrong direction. The following
diagram demonstrates the correct placement of CPU in the ZIF socket.
You can see that the two blunt-edged corners should face towards the
socket-lever.

4. Slightly push CPU into socket without applying excessive force while
making sure there is no gap between CPU and socket. Then lower
the socket lever all the way down to the horizontal position and lock it to
secure the CPU in place.

5. The PPGA / FC-PGA 370 CPU requires a set of heatsink/fan to ensure
proper cooling of processor. If heatsink/fan are not already mounted on
your CPU, you must purchase them separately and have it installed. Plug
the cable from heatsink/fan to CPU fan power connector located nearby.
Note that there are several types of CPU fan connectors. Normally, if your
mainboard supports hardware monitoring function, a 3-pin fan power
connector should allow your system to detect the CPU fans speed . The
CPU fan can also run with a 2-pin fan power connector, however, detec­tion of CPU fans speed is not supported. Another type of CPU fan may
feature a large 4-pin fan power connector, which does not support CPU
fan's speed detection and must connect directly to the system power
supply unit.

- 12 -

Step 2.

Set Jumpers

This mainboard is jumperless! The default jumper settings have been set for
the common usage standard of this mainboard. Therefore, you do not need
to reset the jumpers unless you require special adjustments as any of the
following cases:

1. Overclock your CPU

2. Clear CMOS

3. Clear system password

4. Clear the password to power on system by PS/2 keyboard

For first-time DIY system builders, we recommend that you do not change the
default jumper settings if you are not totally familiar with the mainboard
configuration procedures. The factory-set default settings are tuned for opti­mum system performance. For the advanced users who wish to customize
their system, section 3.2 Jumper Settings will provide detailed information on
how to configure your mainboard manually.

Step 3

Install SDRAM System Memory

To install memory, insert SDRAM memory module(s) in any one or two or
three DIMM banks. Note that SDRAM modules are directional and will not
go in the DIMM slots if they are not properly oriented. After the module is
fully inserted into the DIMM slot, lift the clips of both sides of the DIMM bank
to lock the module in place.

- 13 -

Step 4

Install Internal Peripherals in System Case

Before you install and connect the mainboard into your system case, we
recommend that you first assemble all the internal peripheral devices into the
computer housing, including but not limited to the hard disk drive (IDE/
HDD), floppy disk drive (FDD), CD-ROM drive, and ATX power supply unit.
This will greatly facilitate in making the connections to the mainboard de­scribed below.

To install IDE & FDD drives, follow this procedure:

1. Set the required jumpers on each device according to the instructions
provided by the manufacturer. (IDE devices, HDD, and CD-ROM, have to
set jumpers to Master or Slave mode depending on whether you install
more than one device of each kind.)

2. Connect IDE cable and FDD cable on the back-panel of the internal
peripheral devices to the corresponding headers on board. Note that the

cable should be oriented with its colored stripe (usually red or magenta)
connected to pin#1 both on the mainboard IDE or FDD connector and on
the device as well.

3. Connect an available power cable from your system power supply unit
to the back-panel of each peripheral device. Note that the power cable is

directional and cannot fit in if not properly positioned.

- 14 -

Step 5

Mount the Mainboard on the Computer Chassis

1. You may find that there are a lot of different mounting hole positions
both on your computer chassis and on the mainboard. To choose
correct mounting holes, the key point is to keep the back-panel of the
mainboard in a close fit with your system case, as shown below.

2. After deciding on the proper mounting holes, position the studs between
the frame of the chassis and the mainboard. The studs are used to fix the
mainboard and to keep a certain distance between the system chassis
and the mainboard, in order to avoid any electrical shorts between the
board and the metal frame of the chassis. (If your computer case is
already equipped with mounting studs, you will need to tighten screws to
attach the mainboard.)

Note: In most computer housings, you will be able to find 4 or more

attachment points to install mounting studs and then fix the
mainboard. If there arent enough matching holes, then make sure to
install at least 4 mounting studs to ensure proper attachment of the
mainboard.

- 15 -

Step 6

Connect Front Panel Switches/LEDs/Speaker/USB

You can find there are several different cables already existing in the system
case and originating from the computers front-panel devices (HDD LED,
Power LED, Reset Switch, PC Speaker, or USB devices etc.) These cables
serve to connect the front-panel switches, LEDs, and USB connectors to the
mainboards front-panel connectors group, as shown below.

others) which contains FDISK and FORMAT utilities into the FDD.

2. Turn on the system power.

3. First, you must use the FDISK utility to create a primary partition of the
hard disk. You can also add an extended partition if your primary parti-

tion does not use all of the available hard disk space. If you choose to
add an extended partition, you will have to create one or more logical
partitions to occupy all the space available to the extended partition. The
FDISK utility will assign a drive letter (i.e., C:, D:, E:,...) to each partition
which will be shown in the FDISK program. After FDISK procedure,
reboot your system by using the same system floppy disk.

Note: DOS 6.2x and Windows 95A can only support up to 2.1GB of

HDD partition. If you use the FDISK utility with one of the opera­ting systems mentioned above, you can only install your HDD into

partitions no larger than 2.1GB each.

4. Now, use the FORMAT utility to format all the partitions youve created.
When formatting the primary partition (C:), make sure to use the FORM-

AT C: /S command.

Note: FORMAT C: /S can transfer all the necessary system files into the

primary partition of your hard disk. Then, your HDD will become
a bootable drive.

5. Install all the necessary drivers for CD-ROM, Mouse, etc.

6. Setup the complete operating system according to your OS installation
guide.

of each jumper, you just find the location with a white right angle which
stands for pin 1#. There are several types of pin 1# shown as below:

3-pin and multi (>3) pin jumpers shown as following:
Pin #1 to the left:

Pin #1 on the top:

Pin #1 to the right:

Pin #1 on the bottom:

Jumpers with two pins are shown as for Close [On] or for
Open [Off]. To Short jumper pins, simply place a plastic mini jumpers over
the desired pair of pins.

Caution!

1. Do not remove the mainboard from its antistatic protective packaging
until you are ready to install it.

2. Carefully hold the mainboard by its edges and avoid touching its
components. When putting the mainboard down, place it on top of its
original packaging film, on an even surface, and components side up.
