Chapter 1: Introduction

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 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 ef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 Conguration and Power Interface, Version 2.0 (ACPI)•

Intel I/O External Design Specication (EDS)•

3200 Memory Controller Hub (MCH) External Design Speci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)

X7SBL-LN1/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 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 de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-de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.

1-10

Chapter 1: Introduction

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 de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 insufcient hard drive space for saving the data, you

can be alerted of the potential problem. You can also congure Supero Doctor to

provide you with warnings when the system temperature goes beyond a pre-de-

ned range.

1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion denes a 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 con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.

1-11

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 Con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.

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 suf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 speci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 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.

2-1

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:

1. Always connect the power cord last and always remove it before adding,

removing or changing any hardware components. Make sure that you install the

processor into the CPU LGA 775 socket before you install the CPU heatsink.

2. The Intel LGA 775 Processor package contains the CPU fan and heatsink

assembly. If you buy a CPU separately, make sure that you use only Intel-

certied multi-directional heatsink and fan.

3. Make sure to install the motherboard into the chassis before you install the

CPU heatsink and fan.

4. When purchasing an LGA 775 Processor or when receiving a motherboard

with an LGA 775 Processor pre-installed, make sure that the CPU plastic cap

is in place and none of the CPU pins are bent; otherwise, contact the retailer

immediately.

5. Refer to the MB Features Section for more details on CPU support.

(**Do not drop the CPU on the socket.

Do not move the CPU horizontally or

vertically. Do not rub the CPU against

the surface or against any pins of the

socket to avoid damage to the CPU

or the socket.)

7. With the CPU inside the socket,

inspect the four corners of the CPU

to make sure that the CPU is properly

installed.

8. Use your thumb to gently push the

load lever down to the lever lock.

9. If the CPU is properly installed into

the socket, the plastic PnP cap will be

automatically released from the load

plate when the load lever is pushed

in the lever lock. Remove the PnP cap

from the motherboard.

Note: Please save the plastic

PnP cap. The motherboard

must be shipped with the PnP

cap properly installed to protect

the CPU socket pins. Shipment

without the PnP cap properly

installed will cause damage to

the socket pins.

2-4 Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules.

Warning: Exercise extreme care when installing or removing

DIMM modules to prevent any possible damage. Also note that

!

DIMM Installation

the memory is interleaved to improve performance (see step

1).

Insert the desired number of DIMMs into the memory slots, starting with 1.

DIMM1A. The memory scheme is interleaved so you must install two modules

at a time, beginning with DIMM1A, DIMM1B, then, DIMM2A and DIMM2B

Insert each DIMM module vertically into its slot. Pay attention to the notch 2.

along the bottom of the module to prevent inserting the DIMM module incor-

rectly.

Gently press down on the DIMM module until it snaps into place in the slot. 3.

Repeat for all modules (see step 1 above).

Memory Support

The X7SBL-LN1/LN2 supports up to 8 GB Unbuffered ECC or non-ECC DDR2

800/677 MHz in 4 DIMMs. 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 chan-

nel, non-interleaved memory.

Notes:

Due to the OS limitations, some operating systems may not show more than 1.

4GB of memory.

Both Unbuffered ECC and Non-ECC memory modules can be installed in the 2.

memory slots.

Due to memory allocation to system devices, memory remaining available for 3.

operational use will be reduced when 4 GB of RAM is used. The reduction in

memory availability is disproportional. (Refer to the following Memory Avail-

ability Table for details.)

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads

to prevent the accidental clearing of CMOS. To clear CMOS, use a metal object such

as a small screwdriver to touch both pads at the same time to short the connection.

Always remove the AC power cord from the system before clearing CMOS.

Note: For an ATX power supply, you must completely shut down the system,

3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: The X7SBL-LN1/LN2 supports unbuffered, ECC/Non-ECC DDR2

667/800 MHz memory modules. See Section 2-4 for details on installing

memory.

Question: Why does Microsoft Windows XP (SP2) and Windows Vista show

less memory than what is physically installed?

Answer: Microsoft implemented a design change in Windows XP with Service

Pack 2 (SP2) and Windows Vista. This change is specic to the Physical Ad-

dress Extension (PAE) mode behavior which improves driver compatibility. For

more information, please read the following article at Microsoft’s Knowledge

Base website at: http://support.microsoft.com/kb/888137.

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are not

experiencing any problems with your system. Updated BIOS les are located

on our web site at http://www.supermicro.com/support/bios/. Please check our

BIOS warning message and the information on how to update your BIOS on our

web site. Select your motherboard model and download the BIOS (.rom) le to

your computer. Also, check the current BIOS revision and make sure that it is

newer than your BIOS before downloading. You may choose the zip le or the

.exe le. If you choose the zipped BIOS le, please unzip the BIOS le onto a

bootable device or a USB pen/thumb drive. To ash the BIOS, run the batch

le named “ash.bat” with the new BIOS .rom le from your bootable device or

USB pen/thumb drive. Use the following format:

F:\> ash xxxxxxxx.rom <Enter>

Note: Be sure to insert a space immediately after “ash” and use only the le

named “ash.bat ” to update the BIOS.

When completed, your system will automatically reboot. If you choose the .exe

le, please run the .exe le under Windows to create the BIOS ash oppy disk.

Insert the oppy disk into the system you wish to ash the BIOS. Then, boot

the system to the oppy disk. The BIOS utility will automatically ash the BIOS

without any prompts. Please note that this process may take a few minutes to

complete. Do not be concerned if the screen is paused for a few minutes.

Warning: Do not shut down or reset the system while updating the BIOS to

prevent possible system boot failure!

When the BIOS ashing screen is completed, the system will reboot and will

show “Press F1 or F2”. At this point, you will need to load the BIOS defaults.

3-4

Chapter 3: Troubleshooting

Press <F1> to go to the BIOS setup screen, and press <F9> to load the default

settings. Next, press <F10> to save and exit. The system will then reboot.

Note: The SPI BIOS chip installed on this motherboard is not removable. To

repair or replace a damaged BIOS chip, please send your motherboard to RMA

at Supermicro for service.

Question: What's on the CD that came with my motherboard?

Answer: The supplied compact disc has quite a few drivers and programs that

will greatly enhance your system. We recommend that you review the CD and

install the applications you need. Applications on the CD include chipset drivers

for Windows and security and audio drivers.

Question: After I have installed 4 pieces of 1GB Memory, why does the BIOS only

detect about 3.145 GB of memory during POST?

Answer: Because the chipset does not support memory remapping, and PCI-E

memory requires a great deal of memory, so there is a memory hole located

around the 4GB memory address.

3-4 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be-

fore any warranty service will be rendered. You can obtain service by calling your

vendor for a Returned Merchandise Authorization (RMA) number. When returning

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7SBL-LN1/LN2.

The Phoenix ROM BIOS is stored in a ash chip and can be easily upgraded using

a oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been

added or deleted and might not yet be recorded in this manual. Please refer to

the Manual Download area of the Super Micro web site <http://www.supermicro.

com> for any changes to the BIOS not reected in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and

PS/2® compatible computers. The Phoenix BIOS stores the system parameters,

types of disk drives, video displays, etc. in the CMOS. The CMOS memory requires

very little electrical power. When the computer is turned off, a backup battery pro-

vides power to the CMOS logic, enabling it to retain system parameters. Each time

the computer is powered on, the computer is congured with the values stored in

the CMOS logic by the system BIOS, which gains control at boot-up.

HowToChangetheCongurationData

The CMOS information that determines the system parameters may be changed by

entering the BIOS Setup utility. This Setup utility can be accessed by pressing the

<Delete> key at the appropriate time during system boot. (See below.)

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test. As

the memory is being tested, press the <Delete> key to enter the main menu of the

BIOS Setup utility. From the main menu, you can access the other setup screens,

such as the Security and Power menus. Beginning with Section 4-3, detailed de-

scriptions are given for each parameter setting in the Setup utility.

Warning: Do not shut down or reset the system while updating the BIOS to

!

prevent possible boot failure.

CPU Overheat Alarm

This option allows the user to select the CPU Overheat Alarm setting which

determines when the CPU OH alarm will be activated to provide warning of

possible CPU overheat.

Warning: Any temperature that exceeds the CPU threshold temperature prede

ned by the CPU manufacturer may result in CPU overheat or system instability.

When the CPU temperature reaches this prede ned threshold, the CPU and

system cooling fans will run at full speed.

The options are:

The Default Alarm Setting: Select this setting if you want the CPU overheat

alarm (including the LED and the buzzer) to be triggered when the CPU tem-

peraturereaches about 5oC above the threshold temperature as prede ned by

the CPU manufacturer to give the CPU and system fans additional time needed

for CPUand system cooling.

The Early Alarm Setting: Select this setting if you want the CPU overheat

alarm (including the LED and the buzzer) to be triggered as soon as the CPU

temperature reaches the CPU overheat threshold as prede ned by the CPU

manufacturer. (See the notes on P. 4-23 for more information.)

4-22

Chapter 4: BIOS

CPU Temperature

The CPU Temperature feature will display the CPU temperature status as detected

by the BIOS:

Low – This level is considered as the ‘normal’ operating state. The CPU temperature

is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will

run normally as congured in the BIOS (Fan Speed Control).

User intervention: No action required.

Medium – The processor is running warmer. This is a ‘precautionary’ level and

generally means that there may be factors contributing to this condition, but the CPU

is still within its normal operating state and below the CPU ‘Temperature Tolerance’.

The motherboard fans and CPU will run normally as congured in the BIOS. The

fans may adjust to a faster speed depending on the Fan Speed Control settings.

User intervention: No action is required. However, consider checking the CPU

fans and the chassis ventilation for blockage.

High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem-

perature Tolerance’ has been reached (or has been exceeded) and may activate

an overheat alarm:

The Default Alarm – the Overheat LED and system buzzer will activate if the High

condition continues for some time after it is reached. The CPU fan will run at full

4-23

X7SBL-LN1/LN2 User's Manual

speed to bring the CPU temperature down. If the CPU temperature still increases

even with the CPU fan running at full speed, the system buzzer will activate and

the Overheat LED will turn on.

The Early Alarm – the Overheat LED and system buzzer will be activated exactly

when the High level is reached. The CPU fan will run at full speed to bring the

CPU temperature down.

Note: In both the alarms above, please take immediate action as shown below.

See CPU Overheat Alarm to modify the above alarm settings.

User intervention: If the system buzzer and Overheat LED has activated, take

action immediately by checking the system fans, chassis ventilation and room

temperature to correct any problems. Note: the system may shut down if it con-

tinues for a long period to prevent damage to the CPU.

Notes: The CPU thermal technology that reports absolute temperatures

(Celsius/Fahrenheit) has been upgraded to a more advanced feature by Intel

in its newer processors. The basic concept is that each CPU is embedded

by a unique temperature information that the motherboard can read. This

‘Temperature Threshold’ or ‘Temperature Tolerance’ has been assigned at

the factory and is the baseline by which the motherboard takes action during

different CPU temperature conditions (i.e., by increasing CPU Fan speed, trig-

gering the Overheat Alarm, etc). Since CPUs can have different ‘Temperature

Tolerances’, the installed CPU can now send its ‘Temperature Tolerance’ to

the motherboard resulting in better CPU thermal management.

Supermicro has leveraged this feature by assigning a temperature status to

certain thermal conditions in the processor (Low, Medium and High). This

makes it easier for the user to understand the CPU’s temperature status,

rather than by just simply seeing a temperature reading (i.e., 25oC).

The information provided above is for your reference only. For more informa-

tion on thermal management, please refer to Intel’s Web site at www.Intel.

System Temperature

This item displays the absolute temperature as detected by the BIOS.

Fan1 - Fan 5

The BIOS will automatically display the status of the fan as specied.

Fan Speed Control Modes

This feature allows you to decide how the system controls the speeds of the

onboard fans. The CPU temperature and the fan speed are correlative. When

the CPU on-die temperature increases, the fan speed will also increase, and

vice versa. If the option is set to “4-pin”, the fan speed will be controlled by Pulse

Width Modulation (PWM). Select “Workstation” if your system is used as a Work-

station. Select “Disable” to disable the fan speed control function to allow the

onboard fans to constantly run at full speed (12V). The Options are: 1. Disable

and 2. 3-pin (server) 3-pin (workstation), 4-pin (server) and 4-pin (workstation).

Do not select 4-pin settings if you have a mix of 3-pin and 4-pin fans.

Voltage Monitoring

The following items will be monitored and displayed:

Vcore A, MCH Core, -12V, V-DIMM, 3.3V, +12V, 5V Standby, 5VDD, PVTT,
Vbatt

Note: In the Windows OS environment, the Supero Doctor III settings take pre-

cedence over the BIOS settings. When rst installed, Supero Doctor III adopts

the temperature threshold settings previously set in the BIOS. Any subsequent

changes to these thresholds must be made within Supero Doctor, since the SD

III settings override the BIOS settings. For the Windows OS to adopt the BIOS

temperature threshold settings, please change the SDIII settings to be the same

as those set in the BIOS.
