Chapter 1  
Product introduction  
Thank you for buying an ASUS® AT3N7A-I 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.  
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.

Motherboard overview  
1.2.1  
Motherboard layout  
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.  
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.

1.4.2  
Memory configurations  
You may install 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMMs into the DIMM  
sockets.  
You may install varying memory sizes in Channel A and Channel B. The system maps  
the total size of the lower-sized channel for the dual-channel configuration. Any excess  
memory from the higher-sized channel is then mapped for the single-channel operation.  
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 memory address limitation on 32-bit Windows® OS, 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 any of the  
following:  
-
-
Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.  
Install a 64-bit Windows® OS when you want to install 4GB or more memory on  
the motherboard.  
This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.  
This motherboard supports up to 4GB on Windows® XP Professional x64 and Windows®  
Vista x64 editions. You may install a maximum of 2GB DIMMs on each slot.

Expansion slot  
In the future, you may need to install expansion cards. 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.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
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.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.5.2  
Configuring 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.  
3.  
Assign an IRQ to the card.  
Install the software drivers for the expansion card.  
1.5.3  
PCI slot  
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that  
comply with PCI specifications.

Jumpers  
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 <Del> key during the boot process and enter BIOS setup to re-enter  
data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default  
position. Removing the cap will cause system boot failure!  
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.

Internal connectors  
1.  
ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)  
These connectors are for ATX power supply plugs. The power supply plugs are  
designed to fit these connectors in only one orientation. Find the proper orientation and  
push down firmly until the connectors completely fit.  
We recommend that you use an ATX 12V Specification 2.0-compliant power supply unit  
(PSU) with a minimum of 400W power rating. This PSU type has 24-pin and 4-pin power  
plugs.  
If you intend to use a PSU with 20-pin and 4-pin power plugs, ensure that the 20-pin  
power plug can provide at least 15 A on +12 V and that the PSU has a minimum power  
rating of 400W. The system may become unstable or may not boot up if the power is  
inadequate.  
DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the system will  
not boot up.  
We recommend that you use a PSU with higher power output when configuring a  
system with more power-consuming devices or when you intend to install additional  
devices. The system may become unstable or may not boot up if the power is  
inadequate.  
If you are uncertain about the minimum power supply requirement for your system,  
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.

Serial ATA connectors (7-pin SATA1, SATA2, SATA3)  
These connectors are for the Serial ATA signal cables for Serial ATA 3Gb/s hard disk  
drives and optical disk drives. The Serial ATA 3Gb/s is backward compatible with the  
Serial ATA 1.5Gb/s specification. The data transfer rate of the Serial ATA 3Gb/s is faster  
than the standard parallel ATA (133 MB/s).  
Install the Windows® XP Service Pack 1 or later versions before using Serial ATA.  
If you intend to create a Serial ATA RAID set using these connectors, set the SATA  
Mode Select item in the BIOS to [RAID Mode]. See 2.3.4 Storage Configuration for  
details.  
The motherboard does not provide a floppy disk drive connector. You could use a USB  
floppy disk drive when installing Windows® XP operating system on a hard disk drive  
that includes a RAID/AHCI set.  
Due to Windows® XP limitation, Windows® XP may not recognize the USB floppy disk  
drive.  
The motherboard does not support installing Windows® XP OS with SATA ODD under  
RAID/AHCI mode.  
You need to copy RAID driver to other media such as a USB flash disk and load RAID  
driver during installing Windows® Vista OS with SATA ODD.  
For more details on RAID/AHCI, refer to the RAID/AHCI Supplementary Guide included  
in the folder named Manual in the support DVD.

then install the module to a slot opening at the back of the system chassis. This USB  
connector complys with USB 2.0 specification that supports up to 480 Mbps connection  
speed.  
Never connect a 1394 cable to the USB connector. Doing so will damage the motherboard!  
The USB module cable is purchased separately.  
4.  
Chassis intrusion connector (4-1 pin CHASSIS)  
This connector is for a chassis-mounted intrusion detection sensor or switch. Connect  
one end of the chassis intrusion sensor or switch cable to this connector. The chassis  
intrusion sensor or switch sends a high-level signal to this connector when a chassis  
component is removed or replaced. The signal is then generated as a chassis intrusion  
event.  
By default, the pin labeled “Chassis Signal” and “Ground” are shorted with a jumper  
cap. Remove the jumper caps only when you intend to use the chassis intrusion  
detection feature.
