Product introduction
Thank you for buying an ASUS® AT5IONT-I Series motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page ix for the list of accessories.
• AT5IONT-I Series motherboards include AT5IONT-I and AT5IONT-I DELUXE two
models. The package contents vary from models.
• If any of the items is damaged or missing, contact your retailer.
1.1 Before 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.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, 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.
• 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, or components.
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate that the system
is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down
the system and unplug the power cable before removing or plugging in any motherboard
component. The illustration below shows the location of the onboard LED.

1.2 Motherboard overview
1.2.1 Motherboard layout
ASUS AT5IONT-I Series motherboards include AT5IONT-I and AT5IONT-I DELUXE two
models. The layout varies with models. The layout illustrations in this user guide are for
AT5IONT-I DELUXE only.
Ensure that you install the motherboard into the chassis in the correct orientation. The edge
with external ports goes to the rear part of the chassis.
Place this side towards
the rear of the chassis.
ASUS AT5IONT-I Series 1-2
Place four screws into the holes indicated by circles to secure the motherboard to the
chassis. DO NOT overtighten the screws! Doing so can damage the motherboard.

1.3 Central Processing Unit (CPU)
The motherboard comes with an onboard Dual-Core Intel® Atom™ D525 processor and a
specially designed CPU heatsink.
1.4 System memory
1.4.1 Overview
This motherboard comes with two Double Data Rate 3 (DDR3) Small Outline Dual Inline
Memory Modules (SO-DIMM) sockets. The gure illustrates the location of the DDR3 DIMM
sockets:
1-3 Chapter 1: Product introduction
1.4.2 Memory congurations
You may install 512MB, 1GB, and 2GB unbuffered non-ECC DDR3 SO-DIMMs into the DIMM
sockets.
• Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.
• Due to the CPU limitation, when you install 4GB or more memory on the motherboard,
the actual usable memory for the OS can be about 3GB or less. For effective use of
memory, we recommend that you do use a maximum of 3GB system memory.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.

1.5 Expansion slot
In the future, you may need to install an expansion card. The following sub-sections describe
the slot and the expansion cards that it supports.
Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.
1.5.1 Installing an expansion card
To install an expansion card:
1. Before installing the expansion card, read the documentation that came 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 rmly 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.
1.5.2 Conguring an expansion card
After installing the expansion card, congure 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.
3. Install the software drivers for the expansion card.
1.5.3 PCI Express x4 slot (@ x1 speed, with latch)
This motherboard supports PCI Express x4 network cards, SCSI cards and other cards that
comply with the PCI Express specications.

1. Clear RTC RAM (3-pin CLRTC)
This jumper allows 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 onboard button cell battery powers the RAM data in
CMOS, which include system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3
for about 5-10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the
data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
<Del> key during the boot process and enter BIOS setup to re-enter
If the steps above do not help, remove the onboard battery and move the jumper again to
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
