1-2 Chipset Overview
The Intel 3000 chipset, designed for use with UP Pentium 4 and Dual Core Pentium
D Processors, is comprised of two primary components: the Memory Controller Hub
(MCH) and the I/O Controller Hub (ICH7R). With the capabilities provided by the
Intel 3000 chipset, the PDSML-LN1+/PDSML-LN2+ provides the performance and
feature-set required for cost-effective UP servers.
Memory Controller Hub (MCH)
The function of the MCH is to manage the data fl ow between four interfaces: the pro-
cessor interface (FSB), the System Memory Interface (DRAM Controller), the Direct
Media Interface (DMI) and the PCI Express Interface. The MCH is optimized for the
Pentium 4 or Pentium D processor in the LGA775 Land Grid Array Package.
Using a scalable FSB Vcc_CPU, the MCH supports FSB speed up to 1066 MT/s
(266 MHz). The Host Interface features supported include: Hyper-Threading Tech-
nology (HT), Pentium 4 and Pentium D processor FSB interrupt delivery, FSB
Dynamic Bus Inversion (DBI). It integrates a system memory DDR2 controller with
two 64-bit interfaces and supports one or two channels of DDR2 SDRAM.
The I/O Controller (ICH7R) provides the data buffering and interface arbitration re-
quired for the system to operate effi ciently. It also provides the bandwidth needed
for the system to maintain its peak performance. The Direct Media Interface (DMI)
provides the chip-to-chip connection between the MCH and the ICH7R.
The ICH7R supports up to four Serial ATA ports, six USB 2.0 ports and two IDE
devices. In addition, the ICH7R offers the Intel Matrix Storage Technology which
provides various RAID options for data protection and rapid data access. It also
supports the next generation of client management through the use of PROActive
technology in conjunction with Intel's next generation Gigabit Ethernet controller.
Intel ICH7 (ICH7R) System Features
The I/O Controller Hub provides the I/O subsystem with access to the rest of the
system. Functions and capabilities include:
*Advanced Confi guration and Power Interface, Version 2.0 (ACPI)
*Intel I/O External Design Specifi cation (EDS)
* The Intel 3000 Memory Controller Hub (MCH) External Design Specifi cation
(EDS)
*Intel I/O Controller Hub 7 (ICH7R) Thermal Design Guideline

PDSML-LN1+/PDSML-LN2+ User’s Manual
1-3 Special Features
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond when AC
power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must hit the power switch to turn it back on)
or for it to automatically return to a power- on state. See the Power Lost Control
setting in the Advanced BIOS Setup section to change this setting. The default
setting is Last State.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the PDSML-LN1+/LN2+.
The motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for the CPU Cores, memory, +1.5V, +1.8V,
+3.3V, +5V, +12V, -12V, +5V Standby, VTT and Vbat
An onboard voltage monitor will scan these voltages continuously. Once a voltage
becomes unstable, a warning is given or an error message is sent to the screen. The
user can adjust the voltage thresholds to defi ne the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management via BIOS (under
Hardware Monitoring in the Advanced Setting).
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will turn
on the thermal control fan whenever the CPU temperature exceeds a user-defi ned
threshold. The overheat circuitry runs independently from the CPU. Once it de-
tects that the CPU temperature is too high, it will automatically turn on the thermal
fan control to prevent any possible CPU overheat. The onboard chassis thermal
circuitry can monitor the overall system temperature and alert the user when the
chassis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It continues to operate when
the system enters Standby mode. When in sleep mode, the CPU will not run at
full power, thereby generating less heat.
Chapter 1: Introduction
1-11
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to defi ne an overheat temperature. When this
temperature exceeds the predefi ned temperature threshold, both overheat fan and
the warning LED will be activated.
System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notify the user of certain system events. For example, if the system is running
low on virtual memory and there is insuffi cient hard drive space for saving the
data, you can be alerted of the potential problem. You can also confi gure Supero
Doctor to provide you with warnings when the system temperature goes beyond
a pre-defi ned range.
1-5 ACPI Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -
cation defi nes a fl exible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC system, including its
hardware, operating system and application software. This enables the system to
automatically turn on and off peripherals such as CD-ROMs, network cards, hard
disk drives and printers. This also includes consumer devices connected to the PC
such as VCRs, TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with Windows 2000, Windows XP and Windows
2003 Server.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button to make the system enter a SoftOff state. The monitor will be
suspended and the hard drive will spin down. Pressing the power button again will
cause the whole system to wake-up. During the SoftOff state, the ATX power
1-12
PDSML-LN1+/PDSML-LN2+ User’s Manual
supply provides power to keep the required circuitry in the system alive. In case
the system malfunctions and you want to turn off the power, just press and hold
the power button for 4 seconds. This option can be set in the Power section of
the BIOS Setup routine.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the Standby or Off state. Note that external modem ring-on
can only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN traffi c is kept to
a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
*Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates.
The PDSML-LN1+/LN2+ can only accommodate 24-pin ATX power supply. Al-
though most power supplies generally meet the specifi cations required by the
motherboard, some are inadequate. You should use one that will supply at least
400W of power. In addition, the 12V 8-pin power connector is also required for
adequate power supply to the system. Also your power supply must supply 1.5A
for the Ethernet ports.
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specifi cation 2.01 or above. It must also be SSI compliant (info at
http://www.ssiforum.org/). Additionally, in areas where noisy power transmission is
present, you may choose to install a line fi lter to shield the computer from noise. It
is recommended that you also install a power surge protector to help avoid problems
caused by power surges.

1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive
controller that is compatible with industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock genera-
tor, drive interface control logic and interrupt and DMA logic. The wide range of
functions integrated onto the Super I/O greatly reduces the number of components
required for interfacing with fl oppy disk drives. The Super I/O supports 360 K, 720
K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s
or 1 Mb/s. It also provides two high-speed, 16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which
support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional Printer
Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
The Super I/O provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

2-1 Static-Sensitive Devices
Electric-Static-Discharge (ESD) can damage electronic com ponents. To
prevent damage to your system board, it is important to handle it very
carefully. The following measures are generally suffi cient to protect your
equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic
bag.
• Handle the board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the motherboard and peripherals back into their antistatic bags when not in
use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the motherboard.
• Use only the correct type of onboard CMOS battery. Do not install the onboard
battery upside down to avoid possible explosion.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.

2-4 Installing DDR2 Memory
Memory Module Installation (See Figure 2-2)
Exercise extreme care when installing or removing memory mod-
ules to prevent any possible damage.
1. Insert each DDR2 memory module vertically into its slot. Pay attention to the
notch along the bottom of the module to prevent inserting the module incor-
rectly. (See support information below.)
2. Gently press down on the memory module until it snaps into place.
Support
The PDSML-LN1+/PDSML-LN2+ supports single/dual channel, ECC/Non ECC
unbuffered DDR2 667/533 SDRAM. Both interleaved and non-interleaved
memory are supported, so you may populate any number of DIMM slots.
(Populating DIMM#1A,DIMM#1B, and/or DIMM#2A, DIMM#2B with memory
modules of the same size and of the same type will result in dual channel,
two-way interleaved memory which is faster than the single channel, non-
interleaved memory. When ECC memory is used, it may take 25-40 seconds
for the VGA to display.)
*Notes:
1. Due to chipset limitation, 8GB Memory can only be supported by the following
operating systems:
32-Bit: Windows 2000 Advanced Server, Windows Server 2003 Enterprise
Edition;
64-Bit: Windows Server 2003 Standard x64 Edition, Windows XP Professional
x64 Edition, Windows Server 2003 Enterprise x64 Edition.
2. You may install a maximum of 2GB DIMMs on each slot; however, only DDR2
533 MHz 2GB density modules are available for this confi guration.
3. Some old-version of DDR2-667 may not match Intel's On-Die-Temperature re-
quirement and will automatically be down-graded to run @ 533 MHz, If this
occurs, contact your memory vendor to check the ODT value.
4. Due to memory allocation to system devices, memory remaining available for
operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. (Refer to the Memory Availability Table
below for details.)
