LAN.
Modem Ring Power-On - The system can be powered on automatically
by activation of the modem ring.
Optional Features
Voltage Monitoring - Monitors various voltages of key elements, such as
the CPU, and other critical system voltage levels to ensure stable current
reach to mainboard components. System voltages include Vcore/ VTT on
CPU, and +5V, +12V, -5V, -12V on system.
Fan Status Monitoring - To prevent overheating of CPU, the CPU fan is
monitored for RPM and failure. (CPU Cooling FAN with RPM sensor is

This section outlines how to install and configure your AB61 mainboard. Refer to the
following mainboard layout to help you identify various jumpers, connectors, slots, and
ports. Then follow these steps designed to guide you through a quick and correct instal-
lation of your system.
3.1Step-by-Step Installation
Accessories Of AB61
3HARDWAREINSTALLATION

- 11 -
Step 1
Install the CPU
1. Mark your CPU Frequency
Checking the working frequency of your cpu that should be clearly
marked on the CPU cover or write your own combination in the space
provided.
2. Pentium II/III Processor Installation
<Locate the Retention Mechanism>
To install a CPU, first turn off your system and remove its cover.
Locate the Retention Mechanism (1) around the Slot 1.
Take care of the Square Cut Mark (1.1).
Fix (1) by inserting Attach Mounts (1.4) up through holes (A1...A4)
in the bottom of the mainboard, and screw the four captive nuts
(1.3).
<Install the CPU>
Insert CPU (2) into the Retention Mechanism (1).
Ensure that the alignment notch in the processor fits over the plug
(1.2), then push processor down firmly until it is seated.
Push the latches (2.1) on the processor outward until they click into
place.
Connect power cable (2.2) of Fan/Heat Sink.

- 12 -
3. Celeron Processor Installation
<Locate the Retention Mechanism>
To install a CPU, first turn off your system and remove its cover.
Insert two Retention Mechanism (3) on opposite side of Slot 1.
Fix (3) by inserting Attach Mounts (4) up through holes (A1...A4) in
the bottom of the mainboard, and screw the four captive nuts (3.1).
<Install the CPU>
Hold the processor (5) so that the Heatsink is facing toward the DIMM
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 -
Step2.
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 custom-
ize their system, section 3.2 Jumper Settings will provide detailed informa-
tion 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
