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.
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

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.

1.5Before you proceed
®
d
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.
When lit, the onboard LED (LED1) indicates that the system is ON,
in sleep mode, or in soft-off mode, a reminder that you should shut
down the system before removing of plugging in any motherboard

The motherboard has three Double Data Rate (DDR) DIMM sockets that
supports up to 3GB non-ECC PC2700/2100/1600 DDR.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.

1.8Expansion slots
The P4SE motherboard has six (6) expansion slots. The following subsections describe the slots and the expansion cards that they support.
1.8.1Configuring 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.

This option tells the clock generator what frequency to send the CPU.
This permits selection of the CPU’s external frequency (or Bus
Clock). The BUS Clock multiplied by the Frequency Multiple equals
the CPU’s internal frequency (the advertised CPU speed).
To select the CPU external frequency using the DIP switches, ensure
that the JEN jumper is set to jumper mode.

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 is
the Space Bar). 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 4.5.1 Power Up Control).
