with it and make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
3. 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. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
7. Set up the BIOS if necessary.
8. Install the necessary software drivers for your expansion card.

2.6.2 Configuring an expansion card
Some expansion cards need an IRQ to operate. Generally, an IRQ must be
exclusively assigned to one function at a time. In a standard design
configuration, 16 IRQs are available but most are already in use. Normally,
6 IRQs are free for expansion cards. If themotherboard has PCI audio
onboard, an additional IRQ will be used. If your motherboard also has MIDI
enabled, another IRQ will be used, leaving 4 IRQs free. Sometimes IRQs
are “shared” by more than one function; in this case, IRQ assignments are
swapped automatically or adjusted through the BIOS firmware.
IMPORTANT! When using PCI cards on shared slots, ensure that the
drivers support “Share IRQ” or that the cards do not need IRQ
assignments. Otherwise, conflicts will arise between the two PCI groups,
making the system unstable and the card inoperable.

ASUS P4S333-M motherboard
4.1
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.
NOTE! 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.
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.

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 <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.
NOTE! 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.

1394
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)

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
memory.
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
BIOS..
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.
88
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.

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.
PC100/133
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.

RDRAM (Rambus DRAM)
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
system.
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
standard.
