1.4Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

•Unplug the power cord from the wall socket before touching any component.

•Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity

•Hold components by the edges to avoid touching the ICs on them.

•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

Important notice on installing Windows® XP 32-bit version

If you install Windows® XP 32-bit version Operating System (OS), the limitation of this OS version is that it may reserve a certain amount of memory space for system devices. We recommend that you install less than 3 GB system memory if you would like to work under Windows® XP 32-bit version OS. The excess memory installation will not cause any usage problem, but it will not give users the benefit of manipulating this excess memory space.

Make sure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components.

			2
1.	Unlock a DIMM socket by pressing	3	DDR2 DIMM notch
	the retaining clips outward.
2.	Align a DIMM on the socket such		1
	that the notch on the DIMM matches
	the break on the socket.
3.	Firmly insert the DIMM into the

socket until the retaining clips snap	1
back in place and the DIMM is
properly seated.
	Unlocked retaining clip

•A DDR2 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.

•The DDR2 DIMM sockets do not support DDR DIMMs. Do not install DDR DIMMs to the DDR2 DIMM sockets.

1.8Expansion slots

In the future, you may need to install expansion cards. The following sub sections describe the slots and the expansion cards that they support.

Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.

1.8.1Installing an expansion card

To install an expansion card:

1.Before installing the expansion card, read the documentation that comes with it and make the necessary hardware settings for the card.

2.Remove the system unit cover (if your motherboard is already installed in a chassis).

3.Remove the bracket opposite the slot that you intend to use. Keep the screw for later use.

4.Align the card connector with the slot and press firmly until the card is completely seated on the slot.

5.Secure the card to the chassis with the screw you removed earlier.

6.Replace the system cover.

1.8.2Configuring an expansion card

After installing the expansion card, configure it by adjusting the software settings.

1.Turn on the system and change the necessary BIOS settings, if any. See

Chapter 2 for information on BIOS setup.

2.Assign an IRQ to the card. Refer to the tables on the next page.

3.Install the software drivers for the expansion card.

	12		PS/2 Compatible Mouse Port*
	13	8	Numeric Data Processor
	14		Primary IDE Channel
	15	10	Secondary IDE Channel

* These IRQs are usually available for ISA or PCI devices.

IRQ assignments for this motherboard

	A	B	C	D
PCI slot 1	used	—	—	—
PCI slot 2	—	used	—	—

When using PCI cards on shared slots, ensure that the drivers support “Share

IRQ” or that the cards do not need IRQ assignments; otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.
