Chapter 1
Introduction
Congratulations on purchasing the P4ITA2 mainboard. The P4ITA2
mainboard is an ATX mainboard that uses a 6-layer printed circuit
board and measures 305 x 244mm. The mainboard features a Socket
423 that accommodates Intel Pentium 4 processors supporting front
side bus (FSB) speeds up to 400 MHz and data bus bandwidths up to
3.2 GB/s.
The P4ITA2 incorporates the Intel Tehama 850 Northbridge and Intel
82801BA (ICH2) Southbridge chipsets, combining support for dual-
channel RAMBUS DRAM (RDRAM), 2X/4X AGP (1.5V only), and
the AC 97 codec.
The Intel 82801I/O controller hub includes an integrated audio-codec
controller that lets the processor efficiently decode sound generated by
the integrated audio system.

Static Electricity Precautions
Components on this mainboard can be damaged by static electricity.
Take the following precautions when unpacking the mainboard and
installing it in a system.
1. Keep the mainboard and other components in their original static-
proof packaging until you are ready to install them.
2. During installation, wear a grounded wrist strap if possible. If you
don’t have a wrist strap, discharge static electricity by touching the
bare metal of the system chassis.
3. Handle the mainboard carefully by the edges. Avoid touching the
components unless it is absolutely necessary. During installation
put the mainboard on top of the static-protection packaging it came
in with the component side facing up.
Pre-Installation Inspection
Inspect the mainboard for damage to the components and
connectors on the board.
If you suspect that the mainboard has been damaged, do not
connect power to the system. Contact your mainboard vendor and
report the damage.

middle jack is for a stereo line-in signal. The right side
jack is for a microphone.
Installing the Processor
This mainboard has a Socket 423 processor socket. When choosing a
processor, consider the performance requirements of the system. Per-
formance is based on the processor design, the clock speed and system
bus frequency of the processor, and the quantity of internal cache
memory and externalcache memory.

CPU Installation Procedure
The following illustration shows CPU installation components:
CPU fan
Pin-1 corner Socket 423
Locking lever Retention modules
Follow these instructions to install the CPU:
1. Pull the CPU socket locking lever away from the
socket to unhook it and raise the locking lever to the
upright position.
2. Identify the pin-1 corner on the CPU socket and the
pin-1 corner on the processor.
3. Match the pin-1 corners and insert the processor into
the socket. Do not use force.
4. Swing the locking lever down and hook it under the
latch on the edge of the socket.
5. Apply thermal grease to the top of the CPU.
6. Insert the CPU cooling fan/heatsink assembly.
7. Plug the CPU fan cable connector into the CPU cool-
ing fan power supply on the mainboard (CFAN).
8. Insert the retention module clips over the edge of the
CPU fan/heatsink assembly.

Installing Memory Modules
This mainboard accommodates 184-pin 2.5V unbuffered Rambus
DRAM (RDRAM) memory modules. The memory chips must be
standard or registered RDRAM. The memory bus runs at 400 MHz.
Installation Procedure
The mainboard has four RIMM (Rambus DIMM) slots that accommo-
date up to 2 GB of memory. You can only install the memory modules
in pairs; therefore, you must install at least two RIMM modules. The
dummy Rambus DRAM modules (C-RIMM) must be inserted in un-
populated slots.
1. Align the memory module with the slot. The RIMM
slots are keyed with notches and the RIMMs are keyed
with cutouts so that they can only be installed correctly.
2. Push the latches on each side of the RIMM slot down.
3. Check that the cutouts on the RIMM module edge
connector match the notches in the RIMM slot.

4. Install the RIMM module into the slot and press it
firmly down so that it seats correctly. The slot latches
are levered upwards and latch on to the edges of the
RIMM when it is installed correctly.
5. Install any remaining RIMM modules.

6. After installing your RIMM modules, insert the C-
RIMM modules in the unoccupied slots:

Other Devices Installation
Floppy Diskette Drive Installation
The mainboard has a floppy diskette drive (FDD) interface ships with
a diskette drive ribbon cable that supports one or two floppy diskette
drives. You can install a 5.25-inch drive and a 3.5-inch drive with
various capacities. The floppy diskette drive cable has one type of
connector for a 5.25-inch drive and another type of connector for a
3.5-inch drive.
IDE Devices
Your mainboard has a primary and secondary IDE channel interface
(IDE1 and IDE2). An IDE ribbon cable supporting two IDE devices is
bundled with the mainboard. IDE devices have jumpers or switches
that are used to set the IDE device as MASTER or SLAVE. Refer to
the IDE device user’s manual.
If you want to install more than two IDE devices, get a second IDE
cable and you can add two more devices to the secondary IDE channel.
When installing two IDE devices on one cable, ensure that one device
is set to MASTER and the other device is set to SLAVE.
This mainboard supports UltraDMA 33/66/100. UDMA is a technol-
ogy that accelerates the performance of devices in the IDE channel.
Install IDE devices that support UDMA and use IDE cables that sup-
port UDMA for better performance.
Expansion Slots Installation
This mainboard has five 32-bit PCI (Peripheral Components Intercon-
nect) expansion slots, one 4xAGP slot, and one Communications and
Networking Riser (CNR) slot.
PCI Slots
PCI slots are used to install expansion cards that have the
32-bit PCI interface.

15
4 x AGP Slot
The 4xAGP slot is used to install a graphics adapter that supports the
4xAGP specification and has a 4xAGP edge connector. The 4xAGP
slot only supports 1.5V 4xAGP and 2xAGP cards.
CNR Slot
This slot is used to insert CNR cards including LAN, Modem, and
Audio functions.
1. Remove a blanking plate from the system case corre-
sponding to the slot you are going to use.
2. Install the edge connector of the add-on card into the
expansion slot. Ensure that the edge connector is cor-
rectly seated in the slot.
3. Secure the metal bracket of the card to the system case
with a screw.

If you have installed a LAN card, use the cable provided with the card
to plug into the mainboard WOL1 connector. This enables the Wake
On LAN (WOL) feature. When your system is in a power-saving
mode, any LAN signal automatically resumes the system. You must
enable this item using the Power Management page of the Setup Util-
ity.

When your system is in a power-saving mode, any modem signal
automatically resumes the system. You must enable this item using the
Power Management page of the Setup Utility. See Chapter 3 for more
information.
USB2: USB port 3, 4
The mainboard has two USB ports installed on the rear edge I/O port
array. However, some computer cases have a special module that
mounts USB ports at the front of the case. If you have this kind of
case, use auxiliary USB connectors USB2 and USB3 to connect the
front-mounted ports to the mainboard.
