System memory
2.5.1 Overview
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets
are available for 3.3Volt (power level) unbuffered Synchronous Dynamic
Random Access Memory (SDRAM) of 16, 32, 64, 128MB, 256, 512 or
1024MB to form a memory size between 16MB and 3GB. One side (with
memory chips) of the DIMM takes up one row on the motherboard.
To use the chipset’s Error Checking and Correction (ECC) feature, you
must use a DIMM with 9 chips per side (standard 8 chips/side + 1 ECC
Memory speed setup is recommended through Configure SDRAM
Timing by SPD (see 4.4.2 Advanced Chipset Setup).
Install memory in any combination as follows:
• For optimum signal integrity, inserting the DIMMs in the following
order is recommended: DIMM1, DIMM2, DIMM3
• SDRAMs used must be compatible with the current PC133/PC100
SDRAM specification.
• DO NOT mix SDRAMs with VC SDRAMs.

2.5.2 General DIMM Notes
This motherboard supports SPD (Serial Presence Detect) DIMMs. This
is the memory of choice for best performance vs. stability.
This motherboard does NOT support registered memory.
SDRAM chips are generally thinner with higher pin density than EDO
(Extended Data Output) chips.
BIOS shows SDRAM memory on bootup screen.
Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided
come in 32, 64, 128, 256, 512MB.
ASUS P4S133-VM motherboard user guide
2.5.3 Memory configurations
Insert the module(s) as shown. Because the number of pins are different
on either side of the breaks, the module will only fit in the orientation
shown. DIMM modules are longer and have different pin contact on each
side and therefore have a higher pin density. SIMM modules have the
same pin contact on both sides.

BIOS setup
ASUS P4S133-VM motherboard
Managing and updating your BIOS
4.1.1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS
along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable
floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a
Flash Memory Writer utility that updates the BIOS by uploading a new
BIOS file to the programmable flash ROM on the motherboard. This file
works only in DOS mode. To determine the BIOS version of your
motherboard, check the last four numbers of the code displayed on the
upper left-hand corner of your screen during bootup. Larger numbers
represent a newer BIOS file.
1. Type FORMAT A:/S at the DOS prompt to create a bootable system
disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk.
2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your
CD-ROM drive) to copy AFLASH.EXE to the boot disk you created.
AFLASH works only in DOS mode. It does not work in the DOS prompt
within Windows and does not work 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.
3. Reboot the computer from the floppy disk.
BIOS setup must specify “Floppy” as the first item in the boot
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
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.
ASUS P4S133-VM motherboard user guide
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
press <Enter>.
Chapter 4: BIOS Setup
4.1.2 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
Contact Information on page x for details) 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
ASUS P4S133-VM motherboard user guide
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.
Chapter 4: BIOS Setup
BIOS Setup program
This motherboard supports a programmable EEPROM 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 EEPROM.
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

ASUS P4S133-VM motherboard
1394 is the IEEE designation for a high performance serial bus tht offers data transfers
at 100/200/400 Mbps. This serial bus defines both a back plane physical layer and a
point-to-point cable-connected virtual bus. The primary application of the cable version
is the integration of I/O connectivity at the back panel of personal computers using a
low-cost, scalable, high-speed serial interface. The 1394 standard also provides new
services such as live connect/disconnect capability for external devices including disk
drives, printers and hand-held peripherals such as scanners and cameras. This is a
new standard to complement the slower USB interface and to compete with the more
expensive SCSI interface.
AC97 (Audio Codec '97)
AC '97 is the next step in enabling PCs with audio quality comparable to consumer
electronics devices. The specification defines new cost-effective options to help
integrate the components necessary to support next-generation auto-intensive PC
applications such as DVD, 3-D multiplayer gaming and interactive music. The
specification also defines new extensions supporting modem and docking to help both
desktop and mobile manufacturers adopt these new technologies more quickly and
cost-effectively. This specification uses software emulation to compete with the PCI
SoundBlaster specification.
ACPI (Advanced Configuration and Power Interface)
The ACPI specification defines a cross-platform interface designed to support many
operating systems. ACPI defines a flexible and abstract hardware interface that
provides a standard way to integrate power management features throughout a PC
system, including hardware, operating system and application software. This enables
the system to automatically turn ON and OFF peripherals such as CD-ROMs, network
cards, hard disk drives, and printers, as well as consumer devices connected to the PC
such as VCRs, TVs, phones, and stereos. With this technology, peripherals will also be
able to activate the PC. For example, inserting a tape into a VCR can turn on the PC,
which could then activate a large-screen TV and high-fidelity sound system.
AGP (Accelerated Graphics Port)
An interface specification that enables high-performance 3D graphics on mainstream
PCs. AGP was designed to offer the necessary bandwidth and latency to perform
texture mapping directly from system memory.
Bus Frequency
Data Transfer Rate
Backup. A copy of a file, directory, or volume on a separate storage device from the
original. This copy is for the purpose of data retrieval in case the original is accidentally
erased, damaged, or destroyed.
BIOS (Basic Input/Output System)
BIOS is a set of routines that affect how the computer transfers data between computer
components, such as memory, disks, and the display adapter. The BIOS instructions
are built into the computer’s read-only memory. BIOS parameters can be configured by
the user through the BIOS Setup program. The BIOS can be updated using the
provided utility to copy a new BIOS file into the EEPROM.
Bit (Binary Digit)
A bit is he basic unit of digital data used by the computer. A bit equals either: 0 or 1.
Boot means to start the computer operating system by loading it into system memory.
When the manual instructs you to “boot” your system (or computer), it means to turn ON
your computer. “Reboot” means to restart your computer. When using Windows 95 or
later, selecting “Restart” from “Start | Shut Down...” will reboot your computer.
ASUS P4S133-VM motherboard user guide
Bus Master IDE
PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and
waiting for mechanical events. Bus master IDE transfers data to/from the memory
without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk
drives are required to support bus master IDE mode.
Byte (Binary Term)
One byte is a group of eight contiguous bits. A byte is used to represent a single
alphanumeric character, punctuation mark, or other symbol.
Cache Memory. A type of RAM that allows a faster from the CPU than a regular RAM.
The cache memory eliminates the CPU wait state. When the CPU reads data from the
main memory, a copy of this data is stored in the cache memory. The next time the
same address, the data is transferred from the cache memory instead of from the main
CODEC (Compressor/Decompressor). A software component that translates video or
audio between its uncompressed form and the compressed form in which it is stored.
COM Port
COM is a logical device name used by to designate the computer serial ports. Pointing
devices, modems, and infrared modules can be connected to COM ports. Each COM
port is configured to use a different IRQ and address assignment.
Concurrent PCI
Concurrent PCI maximizes system performance with simultaneous CPU, PCI and ISA
bus activities. It includes multi-transaction timing, enhanced write performance, a
passive release mechanism and support for PCI 2.1 compliant delayed transactions.
Concurrent PCI provides increased bandwidth, reduced system latencies, improves
video and audio performance, and improves processing of host based applications.
CPU (Central Processing Unit)
The CPU, sometimes called “Processor,” actually functions as the “brain” of the
computer. It interprets and executes program commands and processes data stored in
memory. Currently, there are socket 370 (for Pentium III FC-PGA and Celeron-PPGA),
socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III), slot 2 (for Xeon),
and slot A (for AMD) processors.
Device Driver
A device driver is a special set of instructions that allows the computer’s operating
system to communicate with devices such as VGA, audio, printer, or modem.
DOS (Disk Operating System)
DOS is the foundation on which all other programs and software applications operate,
including Windows. DOS is responsible for allocating system resources such as
memory, CPU time, disk space, and access to peripheral devices. For this reason, DOS
constitutes the basic interface between you and your computer.
DRAM (Dynamic Random Access Memory)
A type of RAM that requires refresh cycles to prevent the loss of the data stored in it.
There are several different types of DRAM such as, EDO DRAM (Extended Data Output
DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM) and DDR
DRAM, (Double-Data Rate DRAM).
Flash ROM
non-volatile memory device that retains its data even when power is removed. This
device is similar to EPROM, but unlike EPROM which can be erased only using an
ultra-violet light, flash ROM can be electrically erased. Flash ROM is normally used for
system BIOS, which initiates hardware devices and sets up necessary parameters for
the OS. Since the flash ROM contents can be modified, users can easily update the
IDE (Integrated Drive Electronics)
IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the
need for a separate adapter card (in the case for SCSI devices). UltraDMA/33 IDE
devices can achieve up to 33MB/Sec transfer.
Appendix: Glossary
I/O (Input/Output)
The data transfers from the input devices like a keyboard, mouse, or scanner, to the
output devices like a printer or the monitor screen.
I/O Address
The specific memory location for a particular device. Two devices cannot share the
same I/O address space.
IrDA (Infrared Data Association)
An internaltional organization that creates and promotes inter-operable, low cost,
infrared data interconnection standards that support a walk-up, point-to-point model.
The IrDA protocol is designed to support transmission of data between two devices over
short-range point-to-point infrared at speeds between 9.6Kbps and 4Mbps.
ISP (Internet Service Provider)
A company that provides customer access to the Internet and the World Wide Web for a
fee. The ISP also provides Internet utilities and services like e-mail, newsgroup,
weather reports, and a host of others. The user can connect to the ISP using a modem
installed in the computer and connected to a phone line.
LPT Port (Line Printer Port)
Logical device name reserved by DOS for the computer parallel ports. Each LPT port is
configured to use a different IRQ and address assignment.
A set of 57 new instructions designed to accelerate multimedia and communications
applications, such as 3D video, 3D sound, video conference.
A device that allows a computer to talk to another computer through the phone system.
An interconnected computer system linked by telephone wires, or other means.
The OnNow design initiative is a comprehensive, system-wide approach to system and
device power control. OnNow is a term for PC that is always ON but appears OFF and
responds immediately to user or other requests. The OnNow design initiative involves
changes that will occur in the Microsoft Windows operating system, device drivers,
hardware, and applications, and also relies on the changes defined in the Advanced
Configuration and Power Interface (ACPI) specification.
This is an industry-standard designation for memory capacity as a measure of the
speed of the memory bus. New platform requirements ensure that memory does not
become a bottleneck to system performance.
PCI Bus (Peripheral Component Interconnect Local Bus)
PCI bus is a standard specification that defines a 32-bit data bus interface.
PCI Bus Master
The PCI Bus Master can perform data transfer without local CPU help and the CPU can
be treated as one of the Bus Masters. PCI 2.1 supports concurrent PCI operation to
allow the local CPU and bus master to work simultaneously.
POST (Power On Self Test)
Powering on the computer initiates the POST, a series of software-controlled diagnostic
tests. The POST checks system memory, the motherboard circuitry, the display, the
keyboard, the diskette drive, and other I/O devices.
PS/2 Port
PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture
transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be
used on ATX motherboards.
ASUS P4S133-VM motherboard user guide
Developed by Rambus, Inc., this type of memory can deliver up to 1.6GB of data per
second. RDRAM is the first interface standard that can be directly implemented on high
performance VLSI components such as, CMOS DRAMs, memory controllers, and
graphics/video ICs.
RAM (Random Access Memory). The computer’s primary storage area used to write,
store, and retrieve information and program instructions which are passed to the CPU
for processing. The information in RAM can be repeatedly re-written with new data.
Compared to other storage media like magnetic tape, floppy disk, and hard disk, RAM
has an extraordinarily fast access rate. RAM, however, is volatile, which means that the
data stored in it are lost when the system power is turned off, or if power glitches occur.
See also DRAM and SDRAM.
ROM (Read Only Memory)
ROM is nonvolatile memory used to store permanent programs (called firmware) used
in certain computer components. Flash ROM (or EEPROM) can be reprogrammed with
new programs (or BIOS).
SCSI (Small Computer System Interface)
High speed multi-threaded I/O interface defined by the X3T9.2 committee of the
American National Standards Institute (ANSI) for connecting many peripheral devices.
The standard started from 10MBytes/sec to 160MBytes/sec available today.
SDRAM (Synchronous DRAM)
A type of DRAM with access signals that are synchronized with the CPU clock,
eliminating the delay associated with data transfers between the CPU and memory.
SDRAM takes memory access away from the CPU control; internal registers in the
memory accept the request, and lets the CPU do something else while the data
requested is assembled for the next time the CPU talks to the memory.
SPD for SDRAM module
Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using a
EEPROM component on DIMM module for storing module configuration information
inside. The Serial Presence Detect function is implemented using a 2048 bit EEPROM
component. This nonvolatile storage device contains data programmed by the DIMM
manufacturer that identifies the module type and various SDRAM organization and
timing parameters.
System Disk
A system disk contains the core file of an operating system that boots up the operating
TCP/IP (Transmission Control Protocol/Internet Protocol). The communications
protocol used by the UNIX system and the Internet. TCP checks for lost packets, puts
the data from multiple packets into the correct order, and requests that missing or
damaged packets be resent.
USB (Universal Serial Bus)
A 4-pin serial cable bus that allows up to 127 plug and play computer peripherals such
as keyboard, mouse, joystick, scanner, printer, modem, and monitor to share a
bandwidth through a host scheduled token based protocol. This allows attaching or
detaching while the host and other peripherals are in operation. Supports synchronous
and asynchronous transfer types over the same set of wires up to 12Mbit/sec. USB 2.0
provides twice the transfer rate compared to USB 1.0 and competes with the 1394
Computer will automatically wake-up upon receiving a wake-up packet through a
Network interface when it is under power soft-off, suspend or sleep mode.
