User's Manual

NOTICE

If you’ve changed your CPU or overclocked your system, the system may fail to boot up,
even with a Clear CMOS jumper physically resetted. The reason is that NVIDIA’s new
nForce2 chipset introduces a way to reset a Clear CMOS jumper without removing a
chassis. Please follow the steps listed below:

1. Turn off your computer and unplug the power cable. Reconnect it after 30 seconds;

2. Press <Insert > and then press your computer’s start button. Continue holding <Insert>
until the system begins the POST (Power-On Self Test);

3. Immediately press <Del> to enter the BIOS;

4. Select ‘Load Optimized Defaults’ to return your system to a bootable condition; then
select ‘SAVE to CMOS and EXIT’;

5. Reboot your system.

Moreover, if your system fails to boot up after you reset the CPU FSB, select “SAVE to
CMOS and EXIT” in the BIOS. After the system restarts, there is on screen a message
warning you not to reset or turn off your computer:

Warning! New setting is updating now
Do not Reset or Shutdown the system

Your system works after the BIOS is updated.

WARNING

Thermal issue is highly essential for processors with a speed of 600MHz and above.
Hence, we recommend you to use the CPU fan qualified by AMD or motherboard
manufacturer. Meanwhile, please make sure CPU and fan are securely fastened well.
Otherwise, improper fan installation not only gets system unstable but also could
damage both CPU and motherboard because insufficient thermal dissipation.

If you would like to know more about thermal topic please see AMD website for
detailed thermal requirement through the address:

of your mainboard (between the back panel connectors and the DIMM
memory slots).

2. Pull the CPU ZIF socket lever slightly sideways away from the socket to
unlock the lever, and then bring it to an upwardly vertical position.

3. Place your AMD AthlonXP/Athlon/Duron processor in the socket A. Note
that the CPU's edges have been purposely designed non-symmetrically to
prevent from inserting the processor in the wrong direction. The following
diagram demonstrates the correct placement of the CPU in the ZIF socket.
You can see that the two blunt-edged corners should face towards the socket

lever.

Blank

S

4. Slightly push the AMD AthlonXP/Athlon/Duron processor into the socket
without applying excessive force while making sure there is no gap between

CPU and socket. Then lower the socket-lever all the way down to its hori­zontal position and lock it to secure the CPU in place.

5. The AMD AthlonXP/Athlon/Duron processor requires a set of heatsink/fan
to ensure proper cooling of the processor. If heatsink/fan have not been al­ready mounted on your CPU, you must purchase the heatsink/fan separately
and have it installed. Plug the cable throught the heatsink/fan in the CPU fan
power connector located nearby. Note that there are several types of CPU
fan connectors. Normally, if your mainboard supports the hardware moni­toring function, a 3-pin fan power connector should allow your system to
detect the CPU fan's speed. The CPU fan can also run with a 2-pin fan power
connector, however, detection of CPU fan's speed is not supported. An­other type of CPU fan may feature a large 4-pin fan power connector, which
does not support CPU fan's speed detection and must be directly connected
to the system's power supply unit. Please refer to the following diagram.

Step 2.

Set Jumpers

The default jumper settings have been set for the common usage standard of
this mainboard. Therefore, you need not to reset the jumpers unless you re­quire special adjustments as the following case:

Clear CMOS Setting

For first-time DIY system builders, we recommend that you not change the
default jumper settings if you are not quite familiar with the mainboard con­figuration procedures. The factory-set default settings are tuned for optimum
system performance. For advanced users who prefer to customize their sys­tem, section 3.2 Jumper Settings provides the detailed information on how
to configure your mainboard manually.

Step 3

Install DDR SDRAM System Memory

To install memory, insert DDR SDRAM memory module(s) in the DIMM
banks. Note that DDR SDRAM modules are directional and will not go in the
DIMM banks if they are not properly oriented. After the module is fully in­serted into the DIMM bank, lift the clips of both sides of the DIMM bank to
lock the module in place.

DDR SDRAM

Step 4

Install Internal Peripherals in System Case

Before you place the mainboard into your system case, we recommend that
you first assemble all the internal peripheral devices into the computer hous­ing, including, but not limited to, the hard disk drive (IDE/HDD), floppy disk
drive (FDD), CD-ROM drive, and ATX power supply unit.

To install IDE & FDD drives, follow these procedures:

1. Set the required jumpers on each device according to the instructions pro­vided by the manufacturer. (IDE, HDD, and CD-ROM have to set jumpers
to Master or Slave mode depending on whether you install more than one
device of each kind.)

2. Connect the IDE cable and FDD cable on the back panel of the internal
peripheral devices to the corresponding headers on board. Note that the
cable should be oriented with its colored stripe (usually red or magenta)
connected to pin#1 of the IDE or FDD connector on the mainboard and
on the device as well.

3. Connect an available power cable from your system power supply unit to
the back panel of each peripheral device. Note that the power cable is di­rectional and cannot fit in if not properly positioned.

- 13 -

Step 5

Mount the Mainboard on the Computer Chassis

1. You may find there are a lot of mounting holes on your computer chassis
and mainboard. To match the holes on both properly, the key point is to
make the back panel of the mainboard in a close fit with your system case,
as shown below.

2. Position the studs between the chassis and the mainboard. The studs are
used to fix the mainboard and to keep a certain distance between them,
for avoiding any electrical shorts in-between.

(If your computer case is already equipped with mounting studs, you need
to tighten the screws to attach the mainboard.)

Note: In most computer housings, you can find 4 or more holes to place

studs for fixing the mainboard. If there aren't enough matching holes,
screw at least 4 studs to ensure the proper attachment of the main­board.

Step 12

System Boot Up For the First-Time

To ensure your system completedly and correctly installed, please refer to the
above installation steps once again before first booting up your system.

1. Insert a system-bootable floppy disk (DOS 6.2X, Windows 9X/NT, or
others), which contains the FDISK and FORMAT utilities.

2. Turn on the system power.

3. First, you need to use the FDISK utility to create a primary partition of the
hard disk. You can also add an extended partition if your primary partition
does not use all of the available hard disk space. If you choose to add an
extended partition, you will have to create one or more logical partitions
to occupy all the space available to the extended partition. The FDISK

utility will assign a drive letter (i.e. C:, D:, E:,......) to each partition shown in

the FDISK program. After the FDISK procedure, reboot your system by
using the same disk.

Note: DOS 6.2X and Windows 95A can only support up to 2.1GB of HDD

partition. If you use the FDISK utility with one of the operating sys­tems mentioned above, you can only install your HDD into any par­titions no larger than 2.1GB.

4. Now, use the FORMAT utility to format all the partitions you've created.
When formatting the primary partition (C:), key in the command, "FOR­MAT C:/S."

Note: FORMAT C:/S can transfer all the necessary system files into the pri-

mary partition of your hard disk. Afterwards, your HDD will become
a bootable drive.

5. Install all the necessary drivers for CD-ROM, Mouse, etc.

6. Setup the complete operating system according to your OS installation
guide.

- 21 -

Step 13

Install Drivers & Software Components

Please note that all the system utilities and drivers are designed for Win 9x/
2000/ME/NT/XP operating systems. Make sure your operating system is
already installed before running the installation programs on CD-ROM.

1. Insert the AN35 Ultra/AN35N Ultra/AN35-400/AN35N-400 bundled CD-

ROM into your CD-ROM drive. The auto-run program will display the
main installation window on screen.

2. Choose "Install Mainboard AN35 Series Driver."

3. Choose "Install NVIDIA Chipset driver" and complete it.

4. Choose "Install USB 2.0 Driver" and complete it. (for Win9x/ME only)

5. Quit (from the auto-run installation program).

- 22 -

3.2 Jumper Settings

several types of Pin #1 as shown below:

3-pin and multi-pin (>3) jumpers shown as follows:
Pin #1 to the left:

Pin #1 on the top:

Pin #1 to the right:

Pin #1 on the bottom:

Jumpers with two pins capped are shown as for Close [On] or
for Open [Off]. To do this, please place a plastic mini cap on the desired pair
of pins.

Caution!

1. Do not remove the mainboard from its antistatic protective packaging
until you are ready to install it.

2. Carefully hold the mainboard by its edges and avoid touching its compo­nents. When putting the mainboard down, place it on top of its original
packaging film, with the component side up.

3. Wear an antistatic wrist strap or take other suitable measures to prevent
electrostatic discharge (ESD) as handling this equipment.

A traditional ATX system remains in the power-off stage when AC power re­sumes from power failure. However, it is inconvenient for a network server or
workstation if there is not an UPS to execute power-on. Thus, this motherboard
supports an AC Power Auto Recovery function to solve this problem. You may
enable the function, "PWRON After PWR-Fail," in the sub-menu of "Power
Management Setup" within the BIOS setup program.

Note 1: The ATX power connector is directional and will not go in

unless the guides match perfectly, making sure that pin#1 is
properly positioned.

Note 2: Make sure the latch of the ATX power connector clicks into

place to ensure a solid attachment.

Note 3: Your ATX power supply must be supplied to ACPI+5V stand-

Note: For AN35 Ultra/AN35N Ultra, installing a DIMM in any

single slot leads to a 64-bit data transfer rate. To activize
the dual-channel feature of a 128-bit data transfer rate, in­stall DIMMs in any of the following sequences:

ØDIMMs 1 & 3,
ØDIMMs 2 & 3, or
ØDIMMs 1 & 2 & 3.

(AN35-400/AN35N-400 does not support the dual-channel mode.)

2. Upgrade Memory:

You can easily upgrade the system memory by inserting additional DDR
SDRAM modules in available DIMM banks. The total system memory is
calculated by simply adding up the memory in all DIMM banks. After up­grade, the new system memory value will automatically be computed and
displayed in the field "Standard CMOS Setup" of BIOS setup program.
