sockets on the mainboard.

Slide the processor into the RM. Push the provessor down firmly,
with even pressure on both sides of the top, until it is seated.

- 13 -

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 in any of the
following cases:

1. Over-clock your CPU

2. Clear CMOS

3. Set the wake up function by keyboard/PS2 mouse

For first-time DIY system builders, we recommend that you do not change
the default jumper settings if you are not totally familiar with 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, two or
three DIMM banks. Note that SDRAM modules are directional and will not
go in the DIMM slots unless properly oriented. After the module is fully
inserted into the DIMM socket, lift the clips of both sides of the DIMM bank
to lock the module in place.

- 14 -

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. 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.

- 15 -

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 a
correct mounting hole, 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 be tween 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 fix the mainboard.
If there aren’t enough matching holes, then make sure to install at
least 3 mounting studs to ensure proper attachment of the
mainboard.

- 16 -

Step 6

Connect Front Panel Switches/LEDs/Speaker

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, etc.)
These cables serve to connect the
front-panel switches and LEDs to the
mainboard’s front-panel connectors
group, as shown below.

1. ATX Soft Power On/Off

2. Power-LED

3. HDD-LED

- 17 -

4. EPMI
(Hardware System Management Interface)

5. Green-LED

6. PC Speaker

7. Hardware Reset Switch

8. Keylock

- 18 -

Step 7

Connect IDE & Floppy Disk Drives

1. IDE cable connector

2. FDD cable connector

Step 8

Connect Other Internal Peripherals

1. IR connector

Step 9

Connect the Power Supply

1. System power connector

- 19 -

Step 10

Install Add-on Cards in Expansion Slots

1. Accelerated Graphics Port (AGP) Card

2. PCI Card

3. ISA Card

- 20 -

Step 11

Connect External Peripherals to Back Panel

You are now ready to put the computer case back together and get on to the
external peripherals connections to your system’s back-panel.

1. PS/2 Mouse and Keyboard

2. USB Devices

3. Parallel Port

4. COM Ports

- 21 -

Step 12

First Time System Boot Up

To assure the completeness and correctness of your system installation, you
may check the above installation steps once again before you boot up your
system for the first time.

1. Insert a bootable system floppy disk (DOS 6.2x, Windows 95/98/NT, or

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 parti­tion 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 device 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
FORMAT 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.

- 22 -

Step 13

Install Drivers & Software Components

Please note that all the system utilities and drivers are designed for Win 9x
operating systems only. Make sure your Windows 9x operating system is
already installed before running the drivers installation CD-ROM programs.

1. Insert the AV61 bundled CD-ROM into your CD-ROM drive. The
auto-run program will display the drivers main installation window on
screen.

2. Select the Mainboard related program.

3. Install AV61 Driver for Win9x/Win NT.

- 23 -

3.2 Jumper Settings

Several hardware settings are made through the use of jumper caps to
connect jumper pins on the mainboard. Pin #1 is located on the bottom
or on the left when holding the mainboard with the keyboard connector
or other back-panel connectors opposite from you, as shown below.

3-pin and multi (>3) pin jumpers show as follows:
Pin #1 on the left:

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 jumper cap 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.

3. Wear an antistatic wrist strap or take other suitable measures to prevent
electrostatic discharge (ESD) whenever handling this equipment.

Set Keyboard & PS/2 Mouse Power-On (JP38)

AV61 mainboard provides an easy power-on by keyboard and PS/2 mouse.

Note: When you enable Keyboard Power-On, you also need to configure

the proper hot-key combination <Ctrl> + < function key F1 ~
F12 > in BIOS setup program.

To Power on the system by keyboard, simply strike the proper hot-key.
(A hot-key is the combination of <Ctrl> + <configured function key
F1 ~ F12>)

To power on the system by PS/2 mouse, you only need to double-click with
the mouse. (Note that power-on by serial mouse is not supported)

To enable/disable either or both keyboard and PS/2 mouse power-on func­tions, follow the steps outlined below:

JP38 1-3, 4-6 (default)

Step 1. Adjust the jumper group JP38 as shown in the following table.

Step 2. Set the Power On field to the proper value (Hot-key or PS/2

which has been powered down.

This following is a list of IRQ, Interrupt ReQuests, which can be
exampled much as the COM ports and LPT port above can. When an
I/O device wants to gain the attention of the operating system, it
signals this by causing an IRQ to occur. When the operation system is
ready to respond to the request, it interrupts itself and performs the
service.

As above, the choices are On and Off.
When set On, activity will neither prevent the system from going into

a power management mode nor awaken it.
