Onboard LED

The motherboard comes with a standby power LED. The green LED lights
up to indicate that the system is ON, in sleep mode, or in soft-off mode.
This is a reminder that you should shut down the system and unplug the
power cable before removing or plugging in any motherboard component.
The illustration below shows the location of the onboard LED.

2.1 Before you proceed

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

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

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

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

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

•

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, or components, or all of
the above articles.

1. Place the heatsink on top of
the installed CPU, making sure
that the four fasteners match
the holes on the motherboard.

Nar r o w end
of t h e groo v e

•

When you buy a boxed Intel® Pentium® 4 processor, the package
includes the CPU fan and heatsink assembly.

•

Your Intel® Pentium® 4 LGA775 heatsink and fan assembly comes in
a push-pin design and requires no tool to install.

•

If you purchased a separate CPU heatsink and fan assembly, make
sure that you have properly applied Thermal Interface Material to
the CPU heatsink or CPU before you install the heatsink and fan
assembly.

•

Make sure that you use Intel®-certied multi-directional heatsink and
fan only.

•

Make sure that you have installed the motherboard to the chassis

before you install the CPU fan and heatsink assembly.

•

Do not buy a boxed Intel® BTX(Balanced Technology Extend) processor.

2.4 System memory

2.4 .1 Ove rv ie w

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has
a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are
notched differently to prevent installation on a DDR DIMM socket.

The gure illustrates the location of the DDR2 DIMM sockets:

2.4 .2 Mem or y con fi gu rat io ns

You may install 256 MB, 512 MB, and 1 GB unbuffered non-ECC DDR2
400/533/667 DIMMs into the DIMM sockets.

• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from

the same vendor. Refer to the DDR2 Qualied Vendors List on the

ASUS web site (www.asus.com).

• Due to chipset resource allocation, the system may detect less than 4 GB
of system memory when you installed four 1 GB DDR memory modules.

• Due to chipset limitation, DDR2 667 4-4-4 is not supported on this
motherboard.

• When installing one or two DIMMs, install the DIMM(s) to the black
slots (DIMM_A2/DIMM_B2).

• Due to shared chipset memory, the total size of momories installed

may reduce 8MB.

• Three DDR2 DIMMs intalled into any three memory sockets will
function in dual-channel asymmetric mode.

• When the total size of memory module(s) installed per channel is

the same (A1+A2=B1+B2), the system will run in Dual Channel
Interleaved mode which provides optimum performance.

• When the total size of each channel is not the same
(A1+A2≠B1+B2), the system will run in Dual Channel Asymmetric

mode.

ASUS P5LD-MR 2-15

2.4 .3 Ins ta ll ing a D IMM

Unplug the power supply before adding or removing DIMMs or other
system components. Failure to do so can cause severe damage to both
the motherboard and the components.

To install a DIMM:

1. Unlock a DIMM socket by
pressing the retaining clips
outward.

2. Align a DIMM on the socket
such that the notch on the
DIMM matches the break on
the socket.

3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the
DIMM is properly seated.

2.4 .4 Rem ov in g a D IM M

Follow these steps to remove a DIMM.

1. Simultaneously press the retaining
clips outward to unlock the DIMM.

2. Remove the DIMM from the socket.

• A DDR2 DIMM is keyed with a notch so that it ts in only one

direction. DO NOT force a DIMM into a socket to avoid damaging the
DIMM.

• The DDR2 DIMM sockets do not support DDR DIMMs. DO NOT install
DDR DIMMs to the DDR2 DIMM sockets.

Support the DIMM lightly with

your ngers when pressing the

retaining clips. The DIMM might

get damaged when it ips out

with extra force.

3. Remove the bracket opposite the slot that you intend to use. Keep
the screw for later use.

4. Align the card connector with the slot and press rmly 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.

2.5 .2 Con fi gu rin g an e x pa ns io n c ar d

After installing the expansion card, congure it by adjusting the software

settings.

1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 4 for information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

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

When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Otherwise,

conicts will arise between the two PCI groups, making the system

unstable and the card inoperable. Refer to the table on the next page for
details.

2.6 Jumpers

1. Clea r R TC R A M (CLR T C 1 )
This jumper allows you to clear the Real Time Clock (RTC) RAM in

CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Remove the onboard battery.

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the

cap on pins 2-3 for about 5~10 seconds, then move the cap back
to pins 1-2.

4. Re-install the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOS

setup to re-enter data.

4.2 BIOS setup program

This motherboard supports a programmable rmware chip 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,

reconguring your system, or prompted to“Run Setup.” This section
explains how to congure your system using this utility.

Even if you are not prompted to use the Setup program, you can change

the conguration of your computer in the future. For example, you can

enable the security password feature or change the power management

settings. This requires you to recongure your system using the BIOS Setup
program so that the computer can recognize these changes and record

them in the CMOS RAM of the LPC chip.

The rmware chip 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 <Del> 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, reboot the system by doing any of
the following procedures:

• Restart using the OS standard shut-down procedure.

• Press <Ctrl>+<Alt>+<Del> simultaneously.

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys
to force reset from a running operating system can cause damage to
your data or system. We recommend to always shut-down the system
properly from the operating system.

The Setup program is designed to make it as easy to use as possible. Being
a menu-driven program, it lets you scroll through the various sub-menus and
make your selections from the available options using the navigation keys.

5.1 RAID congurations

The server system/motherboard comes with the Intel® ICH7R and the
LSI Logic Embedded SATA RAID technology built-in the Intel

®

ICH7R

SouthBridge chipset that allows you to congure IDE and Serial ATA hard

disk drives as RAID sets. The motherboard supports the following RAID

congurations:

5.1 .1 RAI D de fin it io ns

RAID 0

(Data striping)

optimizes two identical hard disk drives to read and

write data in parallel, interleaved stacks. Two hard disks perform the same
work as a single drive but at a sustained data transfer rate, double that
of a single disk alone, thus improving data access and storage. Use of two
new identical hard disk drives is required for this setup.

RAID 1

(Data mirroring)

copies and maintains an identical image of
data from one drive to a second drive. If one drive fails, the disk array
management software directs all applications to the surviving drive as
it contains a complete copy of the data in the other drive. This RAID

conguration provides data protection and increases fault tolerance to the

entire system. Use two new drives or use an existing drive and a new drive

for this setup. The new drive must be of the same size or larger than the

existing drive.

RAID 5 stripes both data and parity information across three or more hard

disk drives. Among the advantages of RAID 5 conguration include better

HDD performance, fault tolerance, and higher storage capacity. The RAID 5

conguration is best suited for transaction processing, relational database

applications, enterprise resource planning, and other business systems. Use
a minimum of three identical hard disk drives for this setup.

RAID 10 is a striped conguration with RAID 1 segments whose segments

are RAID 1 arrays. This conguration has the same fault tolerance as

RAID 1, and has the same overhead for fault-tolerance as mirroring alone.
RAID 10 achieves high input/output rates by striping RAID 1 segments. In

some instances, a RAID 10 conguration can sustain multiple simultaneous

drive failure. A minimum of four hard disk drives is required for this setup.

Intel® Matrix Storage. The Intel® Matrix Storage technology supported by
the ICH7R chip allows you to create a RAID 0 and a RAID 1 set using only
two identical hard disk drives. The Intel® Matrix Storage technology creates
two partitions on each hard disk drive to create a virtual RAID 0 and RAID
1 sets. This technology also allows you to change the hard disk drive

partition size without losing any data.

If you want to boot the system from a hard disk drive included in a

created RAID set, copy rst the RAID driver from the support CD to a
oppy disk before you install an operating system to the selected hard

disk drive. Refer to section “6.1 RAID driver installation” for details.

5-2 Chapter 5: Driver installation

5.1 .2 Ins ta ll ing S er ial A TA ha rd d isk s

The motherboard supports Serial ATA hard disk drives. For optimal
performance, install identical drives of the same model and capacity when
creating a disk array.

To install the SATA hard disks for a RAID conguration:

1. Install the SATA hard disks into the drive bays.

2. Connect the SATA signal cables.

3. Connect a SATA power cable to the power connector on each drive.

5.1 .3 Set ti ng th e RA ID it em in B IO S

You must set the RAID item in the BIOS Setup before you can create a RAID
set(s). To do this:

1. Enter the BIOS Setup during POST.

2. Go to the

Main Menu, select IDE Conguration, then press <Enter>.

3. Select the item

Congure SATA As, then press <Enter> to display the

conguration options.

4. Select

RAID from the Congure SATA As item options, then press

<Enter>.

5. Select the item

Onboard Serial-ATA BOOTROM, press <Enter>, then

select Enabled from the options.

6. Save your changes, then exit the BIOS Setup.

Refer to Chapter 4 for details on entering and navigating through the
BIOS Setup.

5.1 .4 RAI D co nfi gu ra tio n ut ili ty

Depending on the RAID_SEL1 jumper setting and the operating system, you
can select a utility to create a RAID set. Refer to section “2.6 Jumpers” for
details on the RAID_SEL1 jumper settings.

Use the Intel® Matrix Storage Manager to create a RAID 0, RAID 1, RAID 0+1,
or software RAID 5 under Windows® 2000/2003 Server operating system.

Use the LSI Logic Embedded SATA RAID Setup Utility t o create a
RAID 0, RAID 1, or RAID 0+1 under Windows® 2000/2003 Server or
Red Hat® Enterprise ver. 3.0 operating system.

Refer to the succeeding sections for details on how to use the RAID

conguration utilities.
