3.7 Expansion Cards
In the future, you may need to install expansion cards. The motherboard has five
PCI expansion slots to support these cards. Follow the steps in the next section
when installing expansion cards.
WARNING! Unplug the system power cord when adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both the motherboard and expansion cards.
3.7.1 Installing an Expansion Card
1. Read the documentation that comes with the expansion card and make any
necessary hardware settings for the card before installing it.
2. Remove the system unit cover and the bracket plate on the slot you intend to use.
Keep the screw for later use.
3. Align the card connectors with the slot and press firmly until the card fits in
place.
4. Secure the card to the slot with the screw you removed earlier.
5. Replace the system cover.
6. Change the necessary BIOS settings, if any.
(see section 4.4.3 PCI Configuration to change the settings.)
7. Install the necessary software drivers for the expansion card.

ASUS A7V266-C User’s Manual
3. HARDWARE SETUP
3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively
assigned to one use. In a standard design, there are 16 IRQs available but most of
them are already in use, leaving 6 IRQs free for expansion cards. If your motherboard
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.
IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Conflicts arise between
the two PCI groups that will make the system unstable or cards inoperable.
The following table lists the default IRQ assignments for standard PC devices. Use

4.1 Managing and Updating Your BIOS
4.1.1 Upon First Use of the Computer System
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.

FTP) (see ASUS CONTACT INFORMATION on page 3 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-

ROM. The boot block is updated automatically only when necessary.
This minimizes the possibilities of boot problems in case of update
failures. When the programming is done, Flashed Successfully appears.
8. Follow the onscreen instructions to continue.
WARNING! 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 still 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 EEPROM that you can update using
the provided utility described in 4.1 Managing and Updating Your BIOS.
The utility is used if you are installing a motherboard, reconfiguring your system,
or prompted to “Run Setup”. This section describes how to configure your system
using this utility.
Even if you are not prompted to use the Setup program, at some time in the future
you may want to change the configuration of your computer. For example, you
may want to enable the Security Password Feature or make changes to the power
management settings. It will then be necessary 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. This
appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup
utility. If you are a little bit late in pressing the mentioned key, POST will continue
with its test routines, thus preventing you from calling up Setup. If you still need to
call Setup, 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 again. But do so only if the first two methods fail.
The Setup program has been 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.
To access the BIOS Setup program, press the <Delete> key after
the computer has run through its POST.
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.

7.1 Glossary
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 pe-
ripherals 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 electron-
ics devices. The specification defines new cost-effective options to help integrate the compo-
nents 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 sup-
porting 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 operat-
ing 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.

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, dam-
aged, or destroyed.
BIOS (Basic Input/Output System)
BIOS is a set of routines that affect how the computer transfers data between computer com-
ponents, 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)
Represents the smallest unit of data used by the computer. A bit can have one of two values:
0 or 1.

7. APPENDIX
Boot
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, select-
ing “Restart” from “Start | Shut Down...” will reboot your computer.
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 interrupt-
ing 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. Abyte 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 au-
dio 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 de-
vices, 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, includ-
ing 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.
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 proto-
col 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.
MMX
A set of 57 new instructions designed to accelerate multimedia and communications applica-
tions, such as 3D video, 3D sound, video conference.
Modem
A device that allows a computer to talk to another computer through the phone system.
Network
An interconnected computer system linked by telephone wires, or other means.
OnNow
The OnNow design initiative is a comprehensive, system-wide approach to system and de-
vice 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 appli-
cations, 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

7. APPENDIX
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.
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 (RandomAccess Memory). The computer’s primary storage area used to write, store,
and retrieve information and program instructions which are passed to the CPU for process-
ing. 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 EE-
PROM 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 proto-
col 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 com-
pared to USB 1.0 and competes with the 1394 standard.
Wake-On-LAN
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.
