FCC/CDC statements
Federal Communications Commission Statement
This device complies with FCC Rules Part 15. Operation is subject to the
following two conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received including interference
that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with
manufacturer’s instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Canadian Department of Communications Statement
This digital apparatus does not exceed the Class B limits for radio noise
emissions from digital apparatus set out in the Radio Interference
Regulations of the Canadian Department of Communications.
This class B digital apparatus complies with Canadian ICES-003.
The use of shielded cables for connection of the monitor to the graphics card is
required to assure compliance with FCC regulations. Changes or modifications
to this unit not expressly approved by the party responsible for compliance
could void the user’s authority to operate this equipment.

Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from
the electrical outlet before relocating the system.
• When adding or removing devices to or from the system, ensure that
the power cables for the devices are unplugged before the signal
cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.
• Before connecting or removing signal cables from the motherboard,
ensure that all power cables are unplugged.
• Seek professional assistance before using an adpater or extension
cord. These devices could interrupt the grounding circuit.
• Make sure that your power supply is set to the correct voltage in your
area. If you are not sure about the voltage of the electrical outlet you
are using, contact your local power company.
• If the power supply is broken, do not try to fix it by yourself. Contact a
qualified service technician or your retailer.
Operation safety
• Before installing the motherboard and adding devices on it, carefully
read all the manuals that came with the package.
• Before using the product, make sure all cables are correctly connected
and the power cables are not damaged. If you detect any damage,
contact your dealer immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from
connectors, slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the
product in any area where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a
qualified service technician or your retailer.

1.5 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. Use a grounded wrist strap or touch a safely grounded object or to a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
5. Before you install or remove any component, ensure that the ATX
power supply is switched off or the power cord is detached from the
power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
1.6 Central Processing Unit (CPU)
The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF)
socket. This socket is specifically designed for the Intel
®
Pentium

1.8 Expansion slots
The P4SE/U2 motherboard has six (6) expansion slots. The following sub-sections
describe the slots and the expansion cards that they support.
1.8.1 Configuring an expansion card
After physically installing the expansion card, configure the card by adjusting the
software settings.
1. Turn on the system and change the necessary BIOS settings, if any.
2. Assign an IRQ to the card. Refer to the tables below.
3. Install the software drivers for the expansion card.
1.7 System memory
The motherboard has three Double Data Rate (DDR) DIMM sockets that supports
up to 3GB non-ECC PC2100/1600 DDR. (Note: PC2700 max. to 4 banks only.)
1. Make sure the memory frequency and bus frequency setting in the
BIOS are the same or set to [Auto] for optimum system performance.
2. A DDR DIMM is keyed with a notch so that it fits in only one direction.
DO NOT force a DIMM into a socket to avoid damaging the DIMM.
3. Visit ASUS website (www.asus.com) for latest DDR333 Qualified Vendor List.

1.9 Jumpers
This section describes and illustrates the jumpers on the motherboard.
1. Keyboard power (3-pin KBPWR1)
This jumper allows you to enable or disable the keyboard wake-up feature. Set
this jumper to pins 2-3 (+5VSB) if you wish to wake up the computer when you
press a key on the keyboard (the default value is [Disabled]). This feature
requires an ATX power supply that can supply at least 1A on the +5VSB lead,
and a corresponding setting in the BIOS (see section 2.5.1 Power Up Control).

2. Clear RTC RAM (CLRCMOS1)
These jumpers allow you to clear the Real Time Clock (RTC) RAM in CMOS.
You can clear the CMOS memory of date, time, and system setup parameters
by erasing the CMOS RTC RAM data. The RAM data in CMOS is powered by
the onboard button cell battery.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the battery.
3. Short the jumper by replacing the jumper cap and removing it after 3 secs.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to
re-enter data.
