1-3 Special Features

Recovery from AC Power Loss

Basic I/O System (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 press the

power switch to turn it back on), or for it to automatically return to a power-on state.

See 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 board. All have

an onboard System Hardware Monitoring chip that supports PC health monitoring.

An onboard voltage monitor will scan these onboard voltages continuously: CPU

cores, +3.3V, +5V, +/-12V, +3.3V Stdby, +5V Stdby, VBAT, CPU Vcore, Memory.

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denethesensitivity

of the voltage monitor.

Fan Status Monitor with Firmware Control

PC health monitoring in the BIOS can check the RPM status of the cooling fans. The

onboard CPU and chassis fans are controlled by Thermal Management via BIOS

(under the Hardware Monitoring section 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 the ther-

mal sensor detects that the CPU temperature is too high, it will automatically turn

on the thermal fans to prevent the CPU from overheating. The onboard chassis

thermal circuitry can monitor the overall system temperature and alert the user when

the chassis temperature is too high.

Note: To avoid possible system overheating, please be sure to provide

adequateairowtoyoursystem.

System Resource Alert

1-10

B1SA4-2750F/B1SA4-2550F Motherboard User’s Manual

This feature is available when the system is 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,youcanalsocongure

Supero Doctor to provide you with warnings when the system temperature, CPU

temperatures,voltagesandfanspeedsgobeyondpredenedthresholds.

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.

In addition to enabling operating system-directed power management, ACPI also

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 XP, Windows Vista and Windows

2008 Operating Systems.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start to blink

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 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. This motherboard draws power from the backplane. Make sure that power

coming from the backplane and chassis is enough to power this motherboard and

the other nodes that reside in the same chassis.

It is strongly recommended that you use a high quality power supply that meets ATX

powersupplySpecication2.02orabove.ItmustalsobeSSIcompliant.(Formore

information, please refer to the web site at http://www.ssiforum.org/). Additionally, in

areas where noisy power transmission is present, you may choose to install a line

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 Advanced Power Management

Intel® Intelligent Power Node Manager (NM)

The Intel® Intelligent Power Node Manager (IPNM) provides your system with

real-timethermalcontrolandpowermanagementformaximumenergyefciency.

AlthoughIPNMSpecicationVersion1.5issupported bytheBMC(Baseboard

Management Controller), your system must also have IPNM-compatible Manage-

abilityEngine(ME)rmwareinstalledtousethisfeature.

Manageability Engine (ME)

The Manageability Engine, which is an ARC controller embedded in the IOH (I/O

Hub), provides Server Platform Services (SPS) to your system. The services

provided by SPS are different from those proveded by the ME on client platforms.

1-8 Introduction to the BMC (Baseboard Management
Controller)

This motherboard incorporates the ASPEED AST2400 Graphics and BMC.

The AST2400 is ASPEED's 5th generation of Advanced PCIe Graphics & Remote

Management Processor, with a mainstream double data rate memory migrating from

DDR2 to DDR3. The AST2400, provides the motherboard with DDR3 support, with

the best cost/performance ratio. The AST2400 is integrated with PCIe 1x support.

In addition to the the AST2400's advanced BMC features. The chip's PCIe 2D

VGA provides servers with a local display, without the added cost and with minimal

pin counts. The embedded ARM9 and DDR3 is clocked at 400MHz to meet the

increasing performance requirements of today's server applications.

2-1 Static-Sensitive Devices

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

avoid damaging 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. 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 that the person handling it is static protected.

CAUTION

Exercise extreme care when installing or removing

DIMM modules to prevent any possible damage.

How to Install SODIMMs

Each of the four nodes has its own memory bank. Populate Channel A rst, the

Channel B. In this example, Channel A of Node 1 is designated as P1-DIMMA1

and Channel B is P1-DIMMB1. Be sure to populate the sockets with SODIMM

memory with the same speed.

Memory Support

Each node on the B1SA4-2750F/B1SA4-2550F Motherboard supports up to 32GB

of up to 1600MHz of unbuffered Non-ECC DDR3 SODIMMs in 2 SODIMM slots.

Memory Population Guidelines

When installing memory modules, the SODIMM slots should be populated in the fol-

lowing order: DIMMA1, DIMMB1.

• Always use DDR3 SODIMM modules of the same size, type and speed.

• Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed

of the slowest DIMM.

• The motherboard will support one DIMM module or three DIMM modules in-

stalled. For best memory performance, install DIMM modules in pairs.

Caution: 1) To prevent damage to the motherboard and its components,

please do not use a force greater than 8 lb/inch on each mounting screw

during motherboard installation. 2) Some components are very close to the

mounting holes. Please take precautionary measures to avoid damaging

these components when installing the motherboard to the chassis.

2-3 Motherboard Installation

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. Although a chassis may have both plastic and metal mounting fas-

teners, metal ones are highly recommended because they ground the motherboard

to the chassis. 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.

Explanation of Jumpers

To modify the operation of the motherboard,

jumpers can be used to choose between op-

tional settings. Jumpers create shorts between

two pins to change the function of the connec-

tor. Pin 1 is identied with a square solder pad

on the printed circuit board.

Note: On two pin jumpers, "Closed"

means the jumper is on, and "Open"

means the jumper is off the pins.

3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: Please see Section 2-2 for a comprehensive answer.

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 website 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 to make sure that it is newer than

your BIOS before downloading. Please unzip the BIOS le onto a bootable device

or a USB pen/thumb drive. To ash the BIOS, run the batch le named "ami.bat"

with the new BIOS ROM le from your bootable device or USB pen/thumb drive.

Use the following format:

F:\> ami.bat BIOS-ROM-lename.xxx <Enter>

Note: Always use the le named “ami.bat” to update the BIOS, and inser t

a space between "ami.bat" and the lename. The BIOS-ROM-lename

will bear the motherboard name (i.e., B1SA4) and build date code as the

extension. For example, "B1SA41.218". When completed, your system

will automatically reboot.

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

Each main BIOS menu option is described in this manual. The Main BIOS setup

menu screen has two main frames. The left frame displays all the options that can

be congured. Grayed-out options cannot be congured. Options in blue can be

congured by the user. The right frame displays the key legend. Above the key

legend is an area reserved for a text message. When an option is selected in the

left frame, it is highlighted in white. Often a text message will accompany it. (Note:

the AMI BIOS has default text messages built in. Supermicro retains the option to

include, omit, or change any of these text messages.)

The AMI BIOS setup utility uses a key-based navigation system called "hot keys".

Most of the AMI BIOS setup utility "hot keys" can be used at any time during the

setup navigation process. These keys include <F1>, <F4>, <Enter>, <ESC>, arrow

keys, etc.

Note: Options printed in Bold are default settings.

How To Change the Conguration Data

The conguration data that determines the system parameters may be changed by

entering the AMI BIOS setup utility. This setup utility can be accessed by pressing

<Del> at the appropriate time during system boot.

Appendix A

BIOS Error Beep Codes

During the POST (Power-On Self-Test) routines, which are performed each time

the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue

with bootup. The error messages normally appear on the screen.

Fatal errors will not allow the system to continue to bootup. If a fatal error oc-

curs, you should consult with your system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of audible beeps.

The numbers on the fatal error list correspond to the number of beeps for the

corresponding error.

SuperDoctor III Interface Display Screen-I (Health Information)

B-2 Conguring SuperDoctor® III

The SuperDoctor III program is a Web-based management tool that supports remote

management capability. It includes Remote and Local Management tools. The local

management tool is called the SD III Client. The SuperDoctor III program included

on the CDROM that came with your motherboard allows you to monitor the envi-

ronment and operations of your system. SuperDoctor III displays crucial system

information such as CPU temperature, system voltages and fan status. See the

Figure below for a display of the SuperDoctor III interface.

Note: 1 The default user name and password are ADMIN.

Note 2: In the Windows OS environment, the SuperDoctor III settings take pre-

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

temperature threshold settings previously set in BIOS. Any subsequent changes

to these thresholds must be made within SuperDoctor, since the settings over-

ride the BIOS settings. For the Windows OS to adopt the BIOS temperature

threshold settings, please change the SD III Client settings to be the same as

those set in BIOS.

UEFI BIOS Recovery

Appendix C

UEFI BIOS Recovery Instructions

Warning! Do not upgrade the BIOS unless your system has a BIOS-related

issue. Flashing the wrong BIOS can cause irreparable damage to the

system. In no event shall Supermicro be liable for direct, indirect, special,

incidental, or consequential damages arising from a BIOS update. If you

need to update the BIOS, do not shut down or reset the system while the

BIOS is updating to avoid possible boot failure.

An Overview to the UEFI BIOS

The Unied Extensible Firmware Interface (UEFI) specication provides a software-

based interface between the operating system and the platform rmware in the

pre-boot environment. The UEFI specication supports an architecture-independent

mechanism for add-on card initialization to allow the UEFI OS loader, which is stored

in the add-on card, to boot up the system. UEFI offers a clean, hand-off control to

a computer system at bootup.

How to Recover the UEFI BIOS Image (-the Main BIOS
Block)

An AMIBIOS ash chip consists of a boot sector block and a main BIOS code block

(a main BIOS image). The boot sector block contains critical BIOS codes, including

memory detection and recovery codes for the user to ash a new BIOS image if the

original BIOS image is corrupted. When the system power is on, the boot sector

codes execute rst. Once it is completed, the main BIOS code will continue with

system initialization and bootup.

Note: Follow the BIOS Recovery instructions below for BIOS recovery

when the main BIOS block crashes. However, when the BIOS Boot sec-

tor crashes, you will need to send the motherboard back to Supermicro

for RMA repair.

To Recover the Main BIOS Block Using a USB-Attached
Device

This feature allows the user to recover a BIOS image using a USB-attached device

without additional utilities used. A USB ash device such as a USB Flash Drive, or

Note: At this point, you may decide if you want to start with BIOS Recovery.

If you decide to proceed with BIOS Recovery, follow the procedures below.

5. When the screen as shown above displays, using the arrow key, select the

item- "Proceed with ash update" and press the <Enter> key. You will see the

progress of BIOS Recovery as shown in the screen below.

a USB CD/DVD ROM/RW device can be used for this purpose. However, a USB

Hard Disk drive cannot be used for BIOS recovery at this time.

To perform UEFI BIOS recovery using a USB-attached device, follow the instruc-

tions below.

1. Using a different machine, copy the "Super.ROM" binary image le into the

disc Root "\" Directory of a USB device or a writeable CD/DVD.

Note: If you cannot locate the "Super.ROM" le in your driver disk, visit

our website at www.supermicro.com to download the BIOS image into a

USB ash device and rename it to "Super.ROM" for BIOS recovery use.

2. Insert the USB device that contains the new BIOS image ("Super.Rom") into

your USB drive and power on the system

3. While powering on the system, keep pressing <Ctrl> and <Home> simultane-

ously on your PS2 or USB keyboard until your hear two short beeps. This

may take from a few seconds to one minute.

4. After locating the new BIOS binary image, the system will enter the BIOS

Recovery page as shown below.
