ASUS A7N8X-LA (Explorer 2) Motherboard

Installing the CPU

Follow these steps to install a CPU.

1. Locate the Socket 462 and open it by

pulling the lever gently sideways

away from the socket. Then lift the

lever upwards. The socket lever

must be fully opened (90 to 100

degrees).

2. Insert the CPU with the correct

orientation. The notched or golden

corner of the CPU must be oriented

toward the inner corner of the socket

base nearest to the lever hinge.

2. Central Processing Unit (CPU)

The motherboard provides a Socket A (462) for CPU installation. AMD processors

offer gigahertz speeds to support all latest computing platforms and applications.

The A7N8X-LA supports AMD Athlon/Athlon XP 3200+ processors. This

motherboard supports 333/266MHz front side bus (FSB), and allows data transfers

of up to 5.4GB/s with PC2700 DDR.

Each AMD CPU has a “marked” corner. This corner is usually indicated with a

notch and/or a golden square or triangle. Refer to this indicator while orienting the

CPU. A fan and a heatsink should be attached to the CPU to prevent overheating.

The CPU fits only in one correct orientation. DO NOT force the CPU into the

socket to prevent bending the pins and damaging the CPU!

3. System memory

The motherboard comes with two Double Data Rate (DDR) Dual Inline Memory

Module (DIMM) sockets. These sockets support up to 2GB system memory using

184-pin unbuffered non-ECC PC2700/PC2100 double-sided DDR DIMMs.

The following figure illustrates the location of the DDR DIMM sockets.

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.

Follow these steps to install a DIMM.

1. Unlock a DIMM socket by pressing

the retaining clips outward.

2. Align a DIMM on the socket such 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 back in

place and the DIMM is properly

seated.

Installing a DIMM

You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into the

DIMM sockets using the memory configurations in this section.

CAUTION: DIMMs are keyed to fit with only one direction. DO NOT force a

DIMM into a socket to avoid damaging the DIMM.

4. E pansion slots

The motherboard has three PCI slots and oneAccelerated Graphics Port (AGP) slot.

To install and configure an expansion card:

1. Install an expansion card following the instructions that came with the chassis.

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

3. Assign an IRQ to the card. Refer to the tables below.

4. Install the drivers and/or software applications for the expansion card

according to the card documentation.

Install only +1.5V AGP cards on this motherboard!

PCI slots

There are three (3) 32-bit PCI slots on this motherboard. The slots support PCI

cards such as a LAN card, SCSI card, USB card, and other cards that comply with

PCI specifications. The figure below shows a typical PCI card installed into a slot.

AGP slot

This motherboard has an Accelerated Graphics Port (AGP) slot that supports

AGP 8X cards. When you buy anAGP card, make sure that you ask for one with

+1.5V specification.

Note the notches on the card golden fingers to ensure that they fit the AGP slot on

your motherboard.

5. Jumper

1. Clear RTC (3-pin CLRTC1)

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 RAM data in CMOS, that include

system setup information, is powered by the onboard button cell battery.

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 (Clear CMOS).

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 jumper caps on default

position. Removing the cap will cause system boot failure!
