1.2Special features
1.2.1Product highlights
Latest processor technology
The PR-DLSR motherboard supports dual Intel® Xeon™ processors via
604-pin surface mount ZIF sockets. The processor features the Intel
NetBurst™ micro-architecture that includes hyper-pipelined technology, a
rapid execution engine, 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
PR-DLSR motherboard supports up to 12GB of system memory using
PC2100/1600 registered ECC DDR DIMMs. The ultra-fast 200MHz
memory bus doubles the speed of the PC100 SDRAM to deliver the
required bandwidth for the latest Internet applications. See page 2-7.
®
Dual-channel Ultra-160 SCSI
The LSI® 53C1010R 64-bit/66MHz PCI SCSI controller is onboard to
support dual-channel Ultra-160 SCSI connectors that provide high-speed
data transfer interfaces.
Advanced 64-bit PCI-X slots
The 64-bit/133MHz expansion slot onboard supports a proprietary riser
card with two PCI-X slots (on both sides). The PCI-X slots maximize I/O
bandwidth for the next generation 64-bit PCI-X cards that support
133/100MHz bus. The PCI-X specification 1.0a allows full peer-to-peer
transactions between PCI buses and provides options for intelligent I/O
and server management cards.
Onboard LAN
The motherboard comes with the Intel® 82551QM Fast Ethernet controller
and the Intel® 82544GC Gigabit Ethernet controller to support the latest
LAN technologies.

Chapter 1: Product introduction
Onboard VGA
The ATI Rage-XL PCI-based VGA controller integrates an 8MB display
SDRAM to provide onboard video solution.
Integrated IDE bridge
The motherboard includes two connectors to support an IDE board with
dual-channel bus master IDE connectors. The IDE connectors support
Ultra DMA 66/33, PIO modes 3 & 4 devices.

1.2.2Value-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 supports BIOS Boot Specification (BBS).
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.

Chapter 1: Product introduction
Chapter 2
This chapter describes the hardware setup
procedures that you have to perform when
installing system components. It includes
details on the switches, jumpers, and
connectors on the motherboard.
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The PR-DLSR uses the
extended ATX form factor that measures 12 x 12 inches (30.5 x 30.5 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.
2.1.1Placement 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.
2.1.2Screw holes
Place seven (7) 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.
The SCSI features are optional. These components are grayed out in
the above motherboard layout.
Chapter 2: Hardware information
2.3Before 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.

2.4.2Installing the CPU
If you are installing two CPUs, install in the CPU socket 2 first.
Follow these steps to install a CPU.
1.Locate the 604-pin ZIF sockets on
the motherboard. Unlock the
socket by pressing the lever
sideways, then lift it up to at least
115° angle.
Make sure that the socket
lever is lifted up to at least
115° angle, otherwise the CPU
does not fit in completely.
2.Position the CPU above the
socket as shown.
3.Carefully insert the CPU into the
socket until it fits in place.
Marked Corner
The CPU fits only in one
correct orientation. DO NOT
force the CPU into the socket
to prevent bending the pins
and damaging the CPU!
4.When the CPU is in place, press it
firmly on the socket while you
push down the socket lever to
secure the CPU. The lever clicks
on the side tab to indicate that it is
locked.

2.4.3Installing the heatsink
Follow these steps to install the CPU heatsink.
1.Carefully place the heatsink on top
of the installed CPU. The heatsink
fits in only one orientation. Take
note of the heatsink placement as
shown.
2.Use a Phillips screwdriver to twist
each of the four screws to secure
the heatsink to the motherboard.
