Force (ZIF) socket. This socket is specifically designed for the Intel
Pentium® 4 478 Processor.

®

P4T533

P4T533 Socket 478

Gold Arrow

The Intel Pentium 4 Processor in the 478-pin package uses the Flip-Chip
Pin Grid Array 2 (FC-PGA2) package technology, and includes the Intel

®

NetBurst™ micro-architecture. The Intel NetBurst micro-architecture
features the hyper-threading technology, hyper-pipeline technology, rapid
execution engine, 533/400MHz system bus, and execution trace cache.
Together, these attributes improve system performance by allowing higher
processor frequencies, faster execution of integer instructions, and a data
transfer rate of 4.2 GB/s and 3.2GB/s.

Gold Mark

Notes on Intel

®

1. This motherboard supports Intel® Pentium 4 CPUs with Hyper­Threading Technology.

2. Hyper-Threading Technology is supported under Windows XP and
Linux 2.4.x (kernel) and later versions only. Under Linux, use the
Hyper-Threading compiler to compile the code. If you are using
any other operating systems, disable the Hyper-Threading
Technology item in the BIOS to ensure system stability and
performance.

3. It is recommended that you install WinXP Service Pack 1.

4. Make sure to enable the Hyper-Threading Technology item in the
BIOS before installing a supported operating system.

5. For more information on Hyper-Threading Technology, visit

www.intel.com/info/hyperthreading.

Hyper-Threading Technology

To use the Hyper-Threading Technology on this motherboard.

1. Buy an Intel

®

Pentium 4 CPU that supports Hyper-Threading Technology.

Install the CPU.

2. Power up the system and enter the BIOS Setup (See Chapter 4). Under
the Advanced Menu, make sure that the item Hyper-Threading
Technology is set to [Enabled]. The item appears only if you installed a
CPU that supports Hyper-Threading Technology.

2.4.2 Installing the CPU

Follow these steps to install a CPU:

1. Locate the Socket 478 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 gold arrow of the CPU
must be oriented toward the inner
corner of the socket base nearest to the
hinge of the lever handle.

The CPU fits in one orientation and should drop easily into place. Do not
force the CPU into the socket to avoid bending the pins. If the CPU
does not fit, check its alignment and look for bent pins.

Gold

90 -10

Arrow

3. Once completely inserted, press the CPU firmly and close the socket
lever until it snaps into its locked position.

4. Install an Intel fan heatsink.

5. Place the CPU fan and heatsink on the CPU. The heatsink should entirely
cover the CPU. Carefully attach the heatsink locking brace to the plastic
clips on the socket base. With the added weight of the CPU fan and
heatsink locking brace, no extra force is required to keep the CPU in
place

T ake care not to scrape the motherboard surface when mounting a clamp­style processor fan, or else damage may occur. When mounting a
heatsink onto your CPU, make sure that exposed CPU capacitors do not
touch the heatsink, or damage may occur!

Do not neglect to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for your Socket
478 processor or else boot-up may not be possible. Socket 478 processors
provide internal thermal sensing: a socket mounted thermal resistor is
not needed.

ASUS P4T533 motherboard user guide

13

2.4.3 Installing the heatsink and fan

The Intel® Pentium® 4 478 Processor requires a specially designed
heatsink and fan assembly to ensure optimum thermal condition and
performance.

When you buy a boxed Intel Pentium 4 478 Processor, the package
includes the heatsink, fan, and retention mechanism.

In case you buy a CPU separately, make sure that you use only Intel
certified heatsink and fan.

Follow these steps to install the CPU heatsink and fan.

1. Place the heatsink on top of the installed CPU, making sure that the
heatsink fits properly on the retention module base.

The retention module base is already installed on the motherboard
upon purchase.

You do not have to remove the retention module base when installing
the CPU or installing other motherboard components.

CPU Heatsink

Retention Module Base

Your boxed Intel Pentium 4 478 Processor package should come with
installation instructions for the CPU, heatsink, and the retention
mechanism. If the instructions in this section do not match the CPU
documentation, follow the latter.

14

Chapter 2: Hardware information

2. Position the fan with the retention mechanism on top of the heatsink.
Align and snap the four hooks of the retention mechanism to the holes
on each corner of the module base.

Make sure that the fan and retention mechanism assembly perfectly
fits the heatsink and module base, otherwise you cannot snap the
hooks into the holes.

DOS prompt within Windows, and does not function with certain memory
drivers that may be loaded when you boot from the hard drive. It is
recommended that you reboot using a floppy disk. Use only a DOS 6.2,
WIN95 / WIN98 boot disk.

3. Reboot the computer from the floppy disk.

NOTE! BIOS setup must specify “Floppy” as the first item in the boot

sequence.

4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.

IMPORTANT! If the word “unknown” appears after Flash Memory:, the

memory chip is either not programmable or is not supported by the ACPI
BIOS and therefore, cannot be programmed by the Flash Memory Writer
utility.

5. Select 1. Save Current BIOS to File from the Main menu and press
<Enter>. The Save Current BIOS To File screen appears.

6. Type a filename and the path, for example, A:\XXX-XX.XXX, then

4.1.3 Updating BIOS procedures

Update the BIOS only if you have problems with the motherboard and
you are sure that the new BIOS revision will solve your problems.
Careless updating may result to more problems with the motherboard!

1. Download an updated ASUS BIOS file from the Internet (see the ASUS
website: www.asus.com) and save to the boot floppy disk you created
earlier.

2. Boot from the floppy disk.

3. At the “A:\” prompt, type AFLASH and then press <Enter>.

4. At the Main Menu, type 2 then press <Enter>. The Update BIOS
Including Boot Block and ESCD screen appears.

5. Type the filename of your new BIOS and the path, for example,
A:\XXX-XX.XXX, then press <Enter>.

To cancel this operation, press <Enter>.

6. When prompted to confirm the BIOS update, press Y to start the
update.

54

Chapter 4: BIOS Setup

7. The utility starts to program the new BIOS information into the Flash
ROM. The boot block is updated automatically only when necessary.
This minimizes the possibility of boot problems in case of update
failures. When the programming is done, the message “Flashed
Successfully” appears.

8. Follow the onscreen instructions to continue.

If you encounter problems while updating the new BIOS, DO NOT turn
off the system because this may cause boot problems. Just repeat the
process, and if the problem persists, load the original BIOS file you
saved to the boot disk. If the Flash Memory Writer utility is not able to
successfully update a complete BIOS file, the system may not boot. If
this happens, call the ASUS service center for support.

4.2 BIOS Setup program

This motherboard supports a programmable Flash ROM that you can
update using the provided utility described in section “4.1 Managing and

updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you may want to
change the configuration of your computer in the future. For example, you
may want to enable the security password Feature or make changes to the
power management settings. This requires you to reconfigure your system
using the BIOS Setup program so that the computer can recognize these
changes and record them in the CMOS RAM of the Flash ROM.

The EEPROM on the motherboard stores the Setup utility. When you start
up the computer, the system provides you with the opportunity to run this
program. Press <Delete> during the Power-On Self Test (POST) to enter
the Setup utility, otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system
chassis. You can also restart by turning the system off and then back on.
Do this last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. It is
a menu-driven program, which means you can scroll through the various
sub-menus and make your selections among the predetermined choices.

Because the BIOS software is constantly being updated, the following
BIOS setup screens and descriptions are for reference purposes only,
and may not exactly match what you see on your screen.
