Chapter 2: Hardware information

2.4.2 Installing the CPU

Follow these steps to install a CPU:

1. Locate the Socket 462 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 notched or golden
corner of the CPU must be oriented
toward the inner corner of the socket
base nearest to the lever hinge.

CAUTION! The CPU 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.

4. Once completely inserted, press the CPU firmly and close the socket
lever until it snaps shut.

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

CAUTION! Take care not to scrape the motherboard surface when

mounting a clamp-style 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!

NOTE! Do not neglect to set the correct Bus Frequency and leave the

CPU Multiple setting at default to avoid start-up problems.

2.5 System memory

2.5.1 Overview

This motherboard uses only Double Data Rate (DDR) Synchronous Dynamic
Random Access Memory (SDRAM) Dual Inline Memory Modules (DIMMs).
These sockets support up to 3GB system memory using non-ECC 200/266/
333MHz DIMMs.

Each DIMM socket/module is two-sided: each side defines one “row” of
memory. 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 3GB.

~ Three (3) sockets are available for both 333MHz-PC2700, 266MHz-PC2100
or 200MHz-PC1600 DDR DIMMs to form a memory size of 64MB to 3GB.

2.6 Expansion slots

The motherboard has five PCI slot and one Accelerated Graphics Port (AGP)
slot.. The following sub-sections describe the slots and the expansion cards
that they support.

WARNING! Unplug your power supply when adding or removing

expansion cards or other system components. Failure to do so may cause
you physical injury and damage motherboard components.

2.6.1 Installing an expansion card

Follow these steps to install an expansion
card.

1. Before installing the expansion card, read
the documentation that came with it and
make the necessary hardware settings.

2. Remove the system unit cover (if your
motherboard is already installed in a
chassis).

3. Remove the bracket opposite the PCI slot.
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 the 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. Sometimes IRQs
are “shared” by more than one function; in this case, IRQ assignments are
swapped automatically or adjusted through the BIOS firmware.

16

Chapter 2: Hardware information

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 inoperative.

9) Primary (Blue) / Secondary (Black) IDE Connectors

(40-1 pin PRIMARY IDE and SECONDARY IDE)

(40-1 pin PROMISE IDE1 and PROMISE2 IDE)
The Primary and Secondary IDE connectors support the IDE hard disk ribbon
cables supplied with the motherboard. Connect the cable’s blue connector
to the motherboard’s primary IDE connector (recommended) or the secondary
IDE connector . Connect the opposite end of the cable to your UltraDMA133/
100/66 device (hard disk drive). If a second hard disk drive is connected,
you may reset its jumper to Slave or Master/Slave mode. Non-UltraDMA133/
100/66 devices should be connected to the secondary IDE connector . BIOS
supports specific device bootup (see 4.6 Boot Menu.) UltraDMA/133 is
backward compatible with DMA100/66/33 and with all with existing DMA
devices and systems.

~ The A7V333 motherboard is supplied with two extra onboard IDE
connectors: one Promise IDE1 and one Promise IDE2. Use them to setup
the RAID 0 or 1 arrays and to support extra ATAPI devices. A total of eight
hard-disks, two on each IDE connector, can be connected to the A7V333;
but, only two can function in a RAID array. See 5.4 Software Setup for
more information about setting up a RAID array.

NOTE! For high-performance and RAID 0 or 1 set ups, always setup

two hard disks with two separate ribbon cables, one for the primary IDE
connector and another for the secondary IDE connector. Usually, both
disks must be set to the Master settings. Also, you may install one
operating system on an IDE drive and another on a SCSI drive and select
the boot disk through BIOS. (See 4.6 Boot Menu.) Do not connect any
other types of IDE devices to the Promise IDE connectors; they support
hard disk drive devices only.

IMPORTANT! UltraDMA100 and UltraDMA133 IDE devices require a

40-pin 80-conductor cable and RAID arrays only operate with such cables.

NOTE: Orient the red

(3x3 pin CPU_, PWR_, CHA_FAN)

Three fan connectors support cooling fans of 350mA (4.2 Watts) or less.
Orient the fans so that airflow flows across the onboard heat sinks instead of
expansion slots. The fan wiring and plug vary depending on the type
employed. Connect the fan cable to the connector, ensuring that the black
wire matches the ground pin. (Use the “Rotation” signal only with a specially
designed fan with a rotation signal. Y ou can monitor the Rotations Per Minute
(RPM) using ASUS PC Probe (see 6. SOFTWARE REFERENCE).

BIOS setup

ASUS A7V333 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. Proceed
to the next page for more information on using AFLASH from a floppy disk.

ASUS POST Flash Utility

An alternative utility for flashing a new BIOS is now available: ASUS POST
Flash; press <AL T> <F2> just after the memory test during boot-up. ASUS
POST Flash functions much like regular AFLASH, but no floppy disk is

required: ASUS POST Flash is built-in to the existing BIOS firmware of
new BIOS editions. First, visit the ASUS website to download the BIOS
that you want to copy it to a floppy disk. To better protect the system,
download both the new version of the BIOS and the BIOS version presently
in use, then copy them to a floppy disk in case you need to reflash the
original BIOS, or if the new one does not function.

To flash a new BIOS using POST Flash Utility, type the filename of the
new BIOS file at the prompt and press <enter>. Then, select the type of
update and select (Y). The new BIOS is recorded into the firmware
memory. Press <ESC> to reboot.

ASUS A7V333 motherboard user guide

49

Using AFLASH from a Floppy Disk:

1. T ype 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. T ype 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 function in the

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
press <Enter>.

50

Chapter 4: BIOS Setup

4.1.2 Updating BIOS procedures

CAUTION! 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. FTP) (see 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:\XXX­XX.XXX, then press <Enter>.

To cancel this operation, press <Enter>.

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

ASUS A7V333 motherboard user guide

51

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.

52

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 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

4.2 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 sub­menus 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.

Exit menu to ensure the values you selected are saved to the CMOS RAM.
The CMOS RAM is sustained by an onboard backup battery and stays on
even when the PC is turned off. When you select this option, a confirmation
window appears. Select [Yes] to save changes and exit.

NOTE! If you attempt to exit the Setup program without saving your

changes, the program prompts you with a message asking if you want to
save your changes before exiting. Pressing <Enter> saves the changes
while exiting.

Exit Discarding Changes

Select this option only if you do not want to save the changes that you made
to the Setup program. If you made changes to fields other than system date,
system time, and password, the BIOS asks for a confirmation before exiting.
