1-2 Chipset Overview

The Intel 3200 chipset, designed for use with an Intel Xeon 3000 sequence proces-

sor in the LGA 775 Land Grid Array Package, is comprised of two primary com-

ponents: the Memory Controller Hub (MCH) and the I/O Controller Hub (ICH9R).

The X7SBL-LN1/LN2 provides the performance and feature-set required for the

mainstream server market.

Memory Controller Hub (MCH)

The function of the MCH is to manage the data ﬂ ow between four interfaces: the

CPU interface, the DDR2 System Memory interface, the PCI Express interface (Note

2), and the Direct Media Interface (DMI). The MCH is optimized for the Intel Xeon

3000 sequence processor in the LGA775 Land Grid Array package. It supports one

or two channels of DDR2 SDRAM.

Intel ICH9R System Features

The I/O Controller (ICH9R) provides the data buffering and interface arbitration

required 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 connection between the MCH and the ICH9R. The ICH9R supports

two PCI-Express devices, six Serial ATA ports, and up to seven USB 2.0 ports/

headers. In addition, the ICH9R 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.

Functions and capabilities include:

Advanced Conﬁ guration and Power Interface, Version 2.0 (ACPI)•

Intel I/O External Design Speciﬁ cation (EDS)•

3200 Memory Controller Hub (MCH) External Design Speciﬁ cation (EDS)•

Intel I/O Controller Hub 9 (ICH9R ) Thermal Design Guideline•

Intel 82573 Platform LAN Connect (PLC) PCI Design•

Note 1: For more information on the ICH9R, please refer to Intel's website at

www.intel.com.

Note 2: The Intel 3200 chipset does not support add-in graphics cards in the

PCI-E interface provided by the Memory Controller Hub (MCH)

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 section to change this setting. (Default: Last State).

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7SBL-LN1/LN2.

All have an onboard System Hardware Monitor chip that supports PC health moni-

toring.

Onboard Voltage Monitors for the CPU Cores, Memory Voltage, +1.8V, +3.3V, +5V,

+5V Standby, +12V, −12V and Vbatt.(via SuperO Doctor)

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.

Users 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 detects

that the CPU temperature is too high, it will automatically turn on the thermal fan

control to prevent any overheat damage to the CPU. The onboard chassis thermal

circuitry can monitor the overall system temperature and alert users when the chas-

sis temperature is too high.

Chapter 1: Introduction

1-11

I/O Virtualization Technology

With the Intel ICH9R built in, the X7SBL-LN1/LN2 supports I/O Virtualization Tech-

nology (VT-d) that enables multiple operating systems and applications to run in

independent partitions. Each partition uses its own subset of host physical memory,

and behaves like a virtual machine (VM), providing isolation and protection across

multiple partitions. This feature is available when a processor that supports I/O

Virtualization Technology is installed on the motherboard.

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 tem-

perature is exceeded, both the overheat fan and the warning LED are triggered.

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS en-

vironment 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-de-

ﬁ ned range.

1-5 ACPI Features

ACPI stands for Advanced Conﬁ guration and Power Interface. The ACPI speciﬁ ca-

tion 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 Operating Systems.

X7SBL-LN1/LN2 User’s Manual

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.

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock generator,

drive interface control logic and interrupt and DMA logic. The Super I/O supports

two 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 sys-

tem. 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 provides functions that comply with the ACPI (Advanced Conﬁ gura-

tion and Power Interface), which includes support of legacy and ACPI power man-

agement through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.

Installation

2-1 Static-Sensitive Devices

Electrostatic-Discharge (ESD) can damage electronic com ponents. To prevent dam-

age 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 as speciﬁ ed by the •

manufacturer. 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.

2-2 Motherboard Installation

Note: Be sure to mount the motherboard into the chassis before you install the

CPU onto the motherboard.

All motherboards have standard mounting holes to ﬁ t different types of chassis.

Make sure that the locations of all the mounting holes for both motherboard and

chassis match. Make sure that the metal standoffs click in or are screwed in tightly.

Then use a screwdriver to secure the motherboard onto the motherboard tray.

2-2

X7SBL-LN1/LN2 User’s Manual

Note: Some components are very close to the mounting holes. Please take

precautionary measures to prevent damage to these components when install-

ing the motherboard to the chassis.

2-3 Processor and Heatsink Installation

Warning: When handling the processor package, avoid placing direct pres-

sure on the label area of the fan.

Notes:
