1.3 Special features

1.3.1 Product highlights

Latest processor technology

The PRL-DL motherboard supports both Intel® Xeon™ processors via dual
604-pin surface mount ZIF sockets. The processor features the Intel
NetBurst™ micro-architecture that includes hyper-pipelined technology , a
rapid execution engine, a 533MHz or a 400MHz system bus, and an
execution trace cache to offer a significant increase in performance. See
page 2-4 for more information.

DDR memory support

Employing the Double Data Rate (DDR) memory technology, the PRL-DL
motherboard supports up to 4GB of system memory using PC2100/1600
registered ECC DDR DIMMs. The ultra-fast 266MHz memory bus doubles
the speed of the PC100 SDRAM to deliver the required bandwidth for the
latest 3D graphics, multimedia, and Internet applications. See page 2-10.

®

Advanced 64-bit PCI slots

The 64-bit/33MHz PCI slots maximize I/O bandwidth for current 64-bit PCI
cards that support 33MHz bus.

ATA/100 IDE support

The dual-channel bus master IDE connectors comply with the ATA/100
protocol and supports ATA/100, Multi-Word DMA Mode2, PIO modes 3 & 4
IDE devices such as ATAPI IDE CD-ROM, CD-R/RW, ZIP, and LS-120
drives.

Third IDE Channel support

The CSB6 South Bridge chip provides a third IDE with PIO mode 3/4
support which provides more device connectivity in this server system.

1-2

Chapter 1: Product introduction

Onboard LAN

The motherboard comes with the Intel® 82540 Gigabit Ethernet controller
to support the latest LAN technologies.

Onboard VGA

The ATI Rage-XL PCI-based VGA controller integrates an 8MB display
SDRAM to provide onboard video solution.

ASUS PRL-DL motherboard user guide

1-3

1.3.2 Value-added solutions

Temperature, fan, and voltage monitoring

The CPU temperature is monitored by the ASUS ASIC to prevent
overheating and damage. The system fan rotations per minute (RPM) is
monitored for timely failure detection. The system voltage levels are
monitored to ensure stable supply of current for critical components.

Dual function power switch

While the system is ON, pressing the power switch for less than 4 seconds
puts the system to sleep mode or to soft-off mode, depending on the BIOS
setting. Pressing the power switch for more than 4 seconds lets the
system enter the soft-off mode regardless of the BIOS setting.

Remote Ring In

This feature allows the system to wake up remotely through an internal or
external modem, if present.

Wake-Up support

The motherboard includes Wake-On-LAN, Wake-On-Ring, and BIOS
Wake-Up features.

Server management

The motherboard comes with an ASMC connector that supports the
optional ASMC-HE/ME/LE card to comply with server reliability, availability,
and serviceability requirements. Remote management response via
remote diagnostics and troubleshooting still works even when the
operating system has stopped functioning.

ACPI ready

The Advanced Configuration power Interface (ACPI) provides more energy
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
protection.

Smart BIOS

The 4Mbit firmware gives an easy-to-use interface that provides 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.

ASUS PRL-DL motherboard

2.1 Motherboard installation

Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The PRL-DL uses the extended
ATX form factor that measures 12 inches x 10.5 inches (30.5 x 26.67 cm).

Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause you physical injury and
damage motherboard components.

2.1.1 Placement direction

When installing the motherboard, make sure that you place it into the
chassis in the correct orientation. The edge with external ports goes to the
rear part of the chassis as indicated in the image below.

2.1.2 Screw holes

Place screws into the holes indicated by circles to secure the motherboard
to the chassis.

Do not overtighten the screws! Doing so may damage the
motherboard.

Place this side towards
the rear of the chassis

2.3 Before you proceed

Take note of the following precautions before you install motherboard
components or change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any
component.

2. Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.

3. Hold components by the edges to avoid touching the ICs on them.

4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.

5. Before you install or remove any component, ensure that the

ATX power supply is switched off or the power cord is
detached from the power supply. Failure to do so may cause

severe damage to the motherboard, peripherals, and/or
components.

2.4.1 Overview

The motherboard comes with dual surface mount 604-pin Zero Insertion
Force (ZIF) sockets. The sockets are designed for the Intel Processor in
the 603/604-pin package with 512KB L2 cache. The processor includes
the Intel® NetBurst™ micro-architecture that features the hyper-pipelined
technology, rapid execution engine, 400/533 MHz system bus, and
execution trace cache. Together, these attributes improve system
performance by allowing higher core frequencies, faster execution of
integer instructions, and data transfer rates of up to 4.26GB/s or 3.2GB/s.

Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.

Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!

The motherboard supports either one or two CPUs. If you are installing
only one CPU, you MUST install it in CPU socket 1.
