3. HARDWARE SETUP
3.3 Getting Started
Before using your computer, you must complete the following steps:
1. Check Motherboard Settings
2. Install Memory Modules
3. Install the Central Processing Unit (CPU)
4. Install Expansion Cards
5. Connect Ribbon Cables, Panel Wires, and Power Supply
6. Setup the BIOS Software
3.4 Motherboard Settings
This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To protect them against damage from static electric-
ity, you should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a
metal object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.
WARNING! Make sure that you unplug your power supply when adding or
removing system components. Failure to do so may cause severe damage to your
motherboard, peripherals, and/or components. The onboard LED when lit acts as
a reminder that the system is in suspend or soft-off mode and not powered OFF.

3.5 System Memory (DDR DIMM)
This motherboard uses only Double Data Rate (DDR) Synchronous Dynamic
Random Access Memory (SDRAM) Dual Inline Memory Modules (DIMMs).
DIMMs come in combinations of single or double-sided types ranging through 64MB,
128MB, 256MB, 512MB and 1GB to form a total memory size of 64MB to 3.5GB.
Each DIMM socket/module is two-sided: each side defines one “row” of memory.
DDR DIMMs support ECC and non-ECC modules; both types are available in
registered (for servers) and unbuffered (for PCs) versions:
~ Four (4) sockets are available for both 266MHz-PC2100 or 200MHz-PC1600
registered DDR DIMMs to form a memory size of 64MB to 3.5GB.
~ Two (2) sockets are available for 266MHz-PC2100 unbuffered DDR DIMMs:
to form a memory size of 64MB to 2GB.
NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.
Install memory, populating the sockets from left to right:

3.5.1 Memory Installation
WARNING! Make sure that you unplug your power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both your motherboard and expansion cards
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. A 184-pin DDR
SDRAM DIMM has a single notch slightly to the right of center. This motherboard
supports three pairs of differential clock signals per DIMM.
Installing a DIMM:
1. Unlock a DIMM socket by pressing the retaining clips outward.
2. Align a DIMM on the socket such that the notches on the DIMM exactly
match the notches in the socket.
3. Firmly insert the DIMM into the socket until the retaining clips snap back in
place.

3.5.2 General DIMM Memo
•
•
DIMMs that have more than 18 chips are not supported on this motherboard.
For the system CPU bus to operate at 200MHz/266MHz, use only PC1600-/
PC2100-compliant DIMMs.
•
•
•
ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
Single-sided DDR DIMMs come in 64, 128, 256 and 512MB; double-sided come in
128, 256, 512MB and 1GB.
Please refer to Appendix 7.1 for a list of Qualified Vendors for DIMMs that have
been tested for use with the A7M266-D motherboard.

1. Locate the CPU socket. 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 notched corner of the CPU must be
oriented toward the inner corner of the socket
base nearest to the lever hinge.
CAUTION! 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.
3. Once completely inserted, press the CPU
firmly and close the socket lever until it snaps into its locked position.
4. Place a CPU fan and heatsink over the CPU. The heatsink should entirely cover
the CPU. Carefully attach the heatsink locking brace to the plastic clips on the
socket base. No extra force is required to keep the CPU in place.
CAUTION! Take care not to scrape the motherboard surface when mounting a
clamp-style processor fan, or damage may occur. When mounting a heatsink
onto your CPU, ensure that exposed CPU capacitors do not touch the heatsink, or
else damage may occur! Refer to heatsink/CPU documentation.
NOTE! To avoid start-up problems, adjust the correct Bus Frequency and
Multiples. (See: 3.4 Motherboard Settings and, 4.4.Advanced BIOS.)

ASUS A7M266-D 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 exclu-
sively 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 moth-
erboard 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 sup-
port “Share IRQ” or that the cards do not need IRQ assignments. Conflicts will
arise between the two PCI groups that will make the system unstable or cards inop-
erable.
The following table lists the default IRQ assignments for standard PC devices. Use

3.9 Starting Up the First Time
1. After all connections are made, close the system case cover.
2. Be sure that all switches are off (in some systems, marked with ).
3. Connect the power supply cord into the power supply located on the
back of your system case according to your system user’s manual.
4. Connect the power cord into a power outlet that is equipped with a surge
protector.
5. You may then turn on your devices in the following order:
a. Your monitor
b. External SCSI devices (starting with the last device on the chain)
c. Your system power. For ATX power supplies, you need to switch on
the power supply as well as press the ATX power switch on the front
of the case.
6. The power LED on the front panel of the system case will light. For
ATX power supplies, the system LED will light when the ATX power
switch is pressed. The LED on the monitor may light up or switch be-
tween orange and green after the system’s if it complies with “green”
standards or if it has a power standby feature. The system will then run
power-on tests. While the tests are running, the BIOS will alarm beeps
or additional messages will appear on the screen. If you do not see any-
thing within 30 seconds from the time you turn on the power, the system
may have failed a power-on test. Recheck your jumper settings and con-
nections or call your retailer for assistance.

4. BIOS SETUP
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 mother-
board, 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
floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the
disk.
2. Type COPYD:\AFLASH\AFLASH.EXEA:\ (assuming D is your CD-
ROM drive) to copy AFLASH.EXE to the just created boot disk.
NOTE: AFLASH works only in DOS mode. It will not work with DOS
prompt in Windows and will not work with certain memory drivers that
may be loaded when you boot from your hard drive. It is recommended
that you reboot using a floppy.
3. Reboot your 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 “unknown” is displayed after Flash Memory:, the memory
chip is either not programmable or is not supported by theACPI BIOS and there-
fore, 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 and then
press <Enter>.
4.1.2 Updating BIOS Procedures
WARNING! Only update your BIOS if you have problems with your mother-
board and you know that the new BIOS revision will solve your problems. Care-
less updating can result in your motherboard having more problems!
1. Download an updated ASUS BIOS file from the Internet (WWW or
FTP) (see ASUS CONTACT INFORMATION on page 3 for details)
and save to the disk you created earlier.
2. Boot from the disk you created earlier.
3. At the “A:\” prompt, type AFLASH and then press <Enter>.
4. At the Main Menu, type 2 and 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, and then press <Enter>.
NOTE: To cancel this operation, press <Enter>.

4. BIOS SETUP
6. When prompted to confirm the BIOS update, press Y to start the update.
7. The utility starts to program the new BIOS information into the flash
ROM. The boot block will be updated automatically only when neces-
sary. This will minimize the chance that a failed update will prevent
your system from booting up. When the programming is finished, Flashed
Successfully will be displayed.
8. Follow the onscreen instructions to continue.
WARNING! If you encounter problems while updating the new BIOS, DO NOT
turn off your system since this might prevent your system from booting up. Just
repeat the process, and if the problem still persists, update the original BIOS file
you saved to disk above. If the Flash Memory Writer utility was not able to
successfully update a complete BIOS file, your system may not be able to boot
up. If this happens, your system will need servicing.

4.2 BIOS Setup Program
This motherboard supports a programmable EEPROM that can be updated using
the provided utility as 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 press-
ing 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 screens and descriptions are for reference purposes only and may not re-
flect your BIOS screens exactly.
