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.

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.

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.

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

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.

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

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.
