You need to complete the following installation steps before you can use your PC.
•Check and Set the Mainboard Settings.
•Install the Central Processing Unit (CPU).
•Install the Memory Modules.
•Install the Expansion Cards.
•Connect the Ribbon Cables, Panel Wires and the Power Supply.

2.3.1. Installation of the CPU
To install your processor, please complete the following set of instructions
1. Locate a small dot marked on the top of the CPU. This mark indicates Pin 1 of the
CPU.
2. Locate Pin 1 for the Socket on the mainboard.
3. There is a lever on the side of the socket. First push this lever sideways and then
lift it to a 90-degree angle.
4. Insert the CPU into the Socket. Please make sure that Pin 1 for the CPU is inserted
into Pin 1 of the Socket.
4. When the CPU is installed correctly push the lever back into place.
5. Install a proper heat sink with cooling fan for proper heat dissipation. Failing
to install a heat sink with cooling fan may cause overheating which will burnout
your CPU and damage your mainboard. The heat sink with cooling fan should be
installed on the retention mechanism that is provided. This retention mechanism is
designed to hold the bigger Heat Sink that is required for the Pentium 4 CPU.
2.3.2. Memory Modules
These mainboards all have three 184-pin DDR SDRAM slots. If registered DDR SDRAM mod-
ules are used then they can support a maximum of 3 GB DRAM. If unbuffered DDR SDRAM
modules are used they can support a maximum of 1.5 GB DRAM
The DDR SDRAM slots are located on the right hand side of the board. To install the DIMM’s
into these slots, make sure the white lever at each side of the slot has been pulled down to
an angle of approximately 45°. Make sure that the DIMM is in the correct orientation. Place
the DIMM on the slot and push down firmly.The white levers will come back up and lock the
module in place.
Heat Sink and Retention Mechanism
You must use an Intel approved Heat Sink. This CPU operates at a very high fre-
quency and therefore heats up very quickly. (A normal heat sink will not be ade-
quate to cool the CPU and the CPU will burn-out.) These heat sinks are very
heavy. A retention mechanism for the Heat Sink has been provided with the main-
board.

2.3. CPU, Memory and Expansion Slots
Hardware Installation

The AZZA P4X2-A MAINBOARD SERIES Page 15
Important: The DIMM’s can only be fitted into the slots in one orientation. Make
sure that the DIMM’s are in the correct orientation and the pins are correctly
aligned before you insert them.
2.3.3. PCI Slots
These boards come with six PCI slots. They are located on the left hand side of the board.
Both PCI and PCI expansion cards may require IRQ’s. This mainboard complies with Plug
and Play (PnP) specifications. Whenever a PnP compliant card is added the system will auto-
matically be configured and the IRQ’s will be assigned automatically.
When you are inserting your PCI card make sure that the pins are correctly aligned. When
the pins are properly aligned with the hole’s in the slot, push down gently.
2.3.4. AGP (Accelerated Graphics Port) Slot
AGP is a dedicated bus slot. It operates at 66 MHz and transfers data at a rate up to 1066
MB/s. This allows 3D applications to run more smoothly. The P4X2-A mainboards each come
with one AGP slot. This slot is able to support 1x, 2x and 4x AGP cards.

NOTE: “Out Of Memory” Error Message
If you have installed more than 512 MB of RAM and are running Microsoft Windows Millennium Edition, Win-
dows 98 Second Edition, Windows 98 or Windows 95 you may experience memory problems. Two symptoms
of these problemsare beingunable to run anMS-DOS sessionwhile you are running Windows orthe computer
may stop responding while Windows isstarting.
Thereare three possible solutionsto thisproblem:
1) Reduce the amount of memory Vcache uses to 512 MB or less by altering the MaxFileCache setting in
the System.ini file.
2) Use the System Configuration Utility to reduce the amount of memoryWindows uses to 512MB or less.
3) Reduce the memory installed on your computer to 512 MB or less.
This problem can also occurif you are using an Advanced GraphicPort (AGP)video adapter.

2.3.5. CNR (Communications Network Riser) Slot (optional for P4X2-AC)
These slots integrate audio, modem and networking on the same card. CNR specifications
support the Audio Codec 97 (AC 97) interface, LAN interfaces, USB interfaces and System
Management Bus (SMBus) interfaces (used specifically to provide Plug and Play functionality).

The P4X2-A mainboards all have two IDE connectors: a primary and secondary. Each IDE
connector can support two IDE drives. These mainboards can therefore support up to four
IDE devices each. If you install two hard drives, you need to configure the second drive to
slave mode in the BIOS setup
. Please refer to your hard drive manual for the appropriate
jumper settings.

2.4.5. ATX Power Supply Connectors
Connector: CN 15-A/ CN15-B/ CN15-C
Type: 20 pin block/2x2 12V/1x6
The mainboards in this series all come with three onboard power supply connectors labled
from CN15-A to CN15-C. CN15-A and the CN15-B are regular ATX power supply connectors
that have been used on all recent motherboards. The CN15-C power connector is for a
+3.3V and +5V power supply. These increased power supplies are necessary to provide ex-
