saving features for operating systems that support OS Direct Power
Management (OSPM).

Concurrent PCI

This feature allows multiple PCI transfers from PCI master buses to the
memory and processor.

1-4

Chapter 1: Product introduction

Chassis intrusion detection

The motherboard supports chassis intrusion monitoring through the ASUS
ASIC. A chassis intrusion event is retained in the system memory for more

control and protection to the motherboard. The BIOS has a boot block
write protection and HD/SCSI/MO/ZIP/CD/Floppy boot selection, and is
Year 2000 certified.

Compliance

Both the BIOS and the hardware levels of the motherboard meet the
stringent requirements for SDG 2.0 certification. The new SDG 2.0
requirements for systems and components are based on the following
high-level goals: support for Plug-and-Play compatibility and power
management for configuring and managing all system components, 32-bit
device drivers, and installation procedures for Windows NT/2000/XP.
Color-coded connectors and descriptive icons make identification easy as
required by the PC ‘99 specification.

2.5 System memory

2.5.1 Overview

The motherboard comes with six Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets. These sockets support up to 4GB
system memory using 184-pin registered PC2100/1600 DIMMs with Serial
Presence Detect (SPD) and Error Check and Correction (ECC).

104 Pins

®

PRL-DLS533

80 Pins

PRL-DLS533 184-Pin DDR DIMM Sockets

A DDR DIMM is keyed with a notch so that it fits in only one direction.
DO NOT force a DIMM into a socket to avoid damaging the DIMM.

The DDR SDRAM technology evolved from the mainstream PC66, PC100,
PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory
however, has the ability to perform two data operations in one clock cycle,
thus providing twice the throughput of SDR memory. For example, a
200MHz DDR DIMM will support a 100MHz memory bus, and a 266MHz
DDR DIMM will support a 133MHz memory bus.

DDR Data Transfer Rate DDR Base Frequency

266MHz 133MHz
200MHz 100MHz

A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.

2.6.3 PCI slots

This motherboard implements the PCI-X (Peripheral Component Interconnect
Extended) bus technology to support up to 100MHz data transfers, or about
800MB/s. This bus technology is primarily designed for servers to increase
the performance of high bandwidth devices such as Gigabit Ethernet cards
and Ultra320 SCSI interfaces. PCI-X is backward compatible with the earlier
PCI bus technology making it possible to install PCI and PCI-X cards at the
same time, but the bus speed will be that of the slowest card. The following
figure shows the five PCI-X slots and one PCI slot on the motherboard.

This connector supports the provided UltraDMA/100/66 IDE hard disk
ribbon cable. Connect the cable’s blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray
connector to the UltraDMA/100/66 slave device (hard disk drive) and
the black connector to the UltraDMA/100/66 master device. It is
recommended that you connect non-UltraDMA/100/66 devices to the
secondary IDE connector. If you install two hard disks, you must
configure the second drive as a slave device by setting its jumper
accordingly. Refer to the hard disk documentation for the jumper
settings. BIOS supports specific device bootup. If you have more than
two UltraDMA/100/66 devices, purchase another UltraDMA/100/66
cable. You may configure two hard disks to be both master devices
with two ribbon cables – one for the primary IDE connector and
another for the secondary IDE connector.

1. Pin 20 on each IDE connector is removed to match the covered
hole on the UltraDMA cable connector. This prevents incorrect
orientation when you connect the cables.

2. The hole near the blue connector on the UltraDMA/100/66 cable is

(3-pin FAN1, FAN2, FAN3)

The fan connectors support cooling fans of 350mA~740mA (8.88W
max.) or a total of 1A~2.22A (26.64W max.) at +12V. Connect the fan
cables to the fan connectors on the motherboard, making sure that the
black wire of each cable matches the ground pin of the connector.

Do not forget to connect the fan cables to the fan connectors. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!

SCSI Connection Notes

This motherboard has two 68-Pin Ultra160/320 SCSI connectors; one for
each of the two channels.

The onboard SCSI chipset incorporates an advanced multimode I/O cell
that supports both single-ended (SE), Ultra2, and Ultra160/320 devices.
With Ultra160/320 devices, the SCSI bus platform performs at full
Ultra160/320 speeds (up to 160MB/s or 320MB/s) and extended cabling
12m (or 25m in a point-to-point configuration). When an SE device is
attached, the bus defaults to an SE speed and 1.5m cable length.

Connect SCSI devices as shown. Each channel should have only one
type of SCSI standard (e.g. Ultra320, Ultra160, Ultra2, Ultra-Wide).
Mixing SCSI devices on the same channel decreases performance of
the slower device.

ASUS PRL-DLS533 motherboard

3.1 Starting up for the first time

1. After making all the connections, replace the system case cover.

2. Be sure that all switches are off.

3. Connect the power cord to the power connector at the back of the system
chassis.

4. Connect the power cord to a power outlet that is equipped with a surge
protector.

5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power (if you are using an ATX power supply , you need to

switch on the power supply as well as press the ATX power switch on
the front of the chassis).

6. After applying power, the power LED on the system front panel case lights
up. For ATX power supplies, the system LED lights up when you press the
ATX power switch. If your monitor complies with “green” standards or if it
has a “power standby” feature, the monitor LED may light up or switch
between orange and green after the system LED turns on. The system
then runs the power-on tests. While the tests are running, the BIOS beeps
or additional messages appear on the screen. If you do not see anything
within 30 seconds from the time you turned on the power , the system may
have failed a power-on test. Check the jumper settings and connections or
call your retailer for assistance.

4.1 Managing and updating your BIOS

4.1.1 Creating a bootable disk

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
sequence.

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 PRL-DLS533 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>.

4-2

Chapter 4: BIOS Setup

4.1.2 Updating the BIOS

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 (WWW or
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:\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
update.

ASUS PRL-DLS533 motherboard user guide

4-3

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.

4-4

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 Flash ROM 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 Flash ROM.

The Flash ROM 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.

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.

above appears. Press <Enter>. The password is set to [Disabled].

A note about passwords

The BIOS Setup program allows you to specify passwords in the Main
menu. The passwords control access to the BIOS during system
startup. Passwords are not case sensitive, meaning, passwords typed
in either uppercase or lowercase letters are accepted. The BIOS Setup
program allows you to specify two different passwords: a Supervisor
password and a User password. If you did not set a Supervisor
password, anyone can access the BIOS Setup program. If you did, the
Supervisor password is required to enter the BIOS Setup program and
to gain full access to the configuration fields.

Forgot the password?

If you forget your password, you can clear it by erasing the CMOS
Real Time Clock (RTC) RAM. The RAM data containing the password
information is powered by the onboard button cell battery. See section
“2.7Switches and jumpers” for information on how to erase the R TC
RAM.
