Chapter 1: Introduction

1-4 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 Advanced BIOS
Setup section to change this setting. The default setting is Last State.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the X8DAH+/X8DAH+-F .
All have an onboard System Hardware Monitor chip that supports PC health moni­toring. An onboard voltage monitor will scan these onboard voltages continuously:
CPU0 Vcore, CPU1 Vcore, 1.5V, 5V, 5VSB, 12V, -12V, 3.3Vcc, 3.3VSB, VBAT and
Vtt. 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 sensi-
tivity 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 chas­sis temperature is too high.

Note: To prevent system overheating, be sure to provide adequate airfl ow
to the system.

CPU Fan Auto-Off in Sleep Mode

The CPU fan becomes active when the power is turned on. It continues to operate
when the system enters the Standby mode. When in the sleep mode, the CPU will
not run at full power, thereby generating less heat.

1-11

X8DAH+/X8DAH+-F User's Manual

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
notif y the user of cer tain system events. For example, you can also confi gure
Supero Doctor to provide you with warnings when the system temperature, CPU
temperat ures, volt ages a nd fan spe eds go beyon d a pre- defi ned range.

1-6 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.

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 both Windows 2000 and Windows 2003
Operating Systems.

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
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.

1-12

Chapter 1: Introduction

1-7 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 X8DAH+/X8DAH+-F can accommodate 24-pin ATX power supplies. Although
most power supplies generally meet the specifi cations required by the CPU, some
are inadequate. In addition, the two 12V 8-pin power connections are also required
to ensure adequate power supply to the system. Also your power supply must sup­ply 1.5A for the Ethernet ports.

Warning: To prevent damage to the power supply or motherboard, please
use a power supply that contains a 24-pin and two 8-pin power connectors.
Be sure to connect these connectors to the 24-pin (JPW1) and the two
8-pin (JPW2, JPW3) power connectors on the motherboard for adequate
power supply to your system. Failure in doing so will void the manufacturer
warranty on your power supply and motherboard.

It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specifi cation 2.02 or above. It must also be SSI compliant (For more
information, please refer to the website 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.

1-8 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 genera­tor, 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 provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage-

X8DAH+/X8DAH+-F User's Manual

ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

1-9 Overview of the Winbond WPCM450 Controller (For
X8DAH+-F Only)

The Winbond WPCM450 Controller is a Baseboard Management Controller (BMC)
that supports the 2D/VGA-compatible Graphics Core with the PCI interface,
Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules. With
blade-oriented Super I/O capability built-in, the WPCM450 Controller is ideal for
legacy-reduced server platforms.

The WPCM450 interfaces with the host system via a PCI interface to communicate
with the Graphics core. It supports USB 2.0 and 1.1 for remote keyboard/mouse/
virtual media emulation. It also provides LPC interface to control Super IO func­tions. The WPCM450 is connected to the network via an external Ethernet PHY
module.

The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, and Platform Environment Control Interface (PECI) buses.

This motherboard has six chassis/system
fan headers (Fan 1 to Fan6) and two
CPU fans (CPU1 Fan/CPUW Fan) on the
motherboard. All these 4-pin fans head­ers are backward compatible with the
traditional 3-pin fans. However, fan speed
control is available for 4-pin fans only.
The fan speeds are controlled by Thermal
Management via Hardware Monitoring in
the Advanced Setting in the BIOS. (The
Default setting is Disabled.) See the table

Explanation of Jumpers

To modify the operation of the mother­board, jumpers can be used to choose
between optional settings. Jumpers cre­ate shorts between two pins to change
the function of the connector. Pin 1
is identifi ed with a square solder pad
on the printed circuit board. See the
motherboard layout pages for jumper
locations.

Note: On two pin jumpers,
"Closed" means the jumper
is on and "Open" means the
jumper i s of f the pin s.

GLAN Enable/Disable

Use JPL1 to enable or disable GLAN
Port1/GLAN Port2 on the mother­board. See the table on the right for
jumper s ettings. The d efault settin g is

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact
pads to prevent t he accident al clearin g of CMOS. To clear CMOS , use a metal
objec t such as a sma ll screwdr iver to touc h both pad s at the same t ime to shor t
the co nnec ti on. A lways rem ove the AC p ower c ord f rom t he syste m befo re cl ear­ing CMOS.

Note: For an ATX power supply, you must completely shut down the sys­tem, remove the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog (JWD) is a syste m monitor th at
can reb oot t he sys tem w hen a s of tware ap­plicat ion han gs. Clo se Pins 1-2 to res et the
system if an app lication ha ngs. Close Pins
2-3 to generate a non-maskable interrupt
signal for the application that hangs. See the

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DAH+/X8DAH+-F. The
AMI ROM BIOS is stored in a Flash EEPROM and can be easily updated. This chap­ter describes the basic navigation of the AMI BIOS Setup Utility setup screens.

Starting BIOS Setup Utility

To enter the AMI BIOS Setup Utility screens, press the <Delete> key while the
system is booting up.

Note: In most cases, the <Delete> key is used to invoke the AMI BIOS
setup screen. There are a few cases when other keys are used, such as
<F1>, <F2>, etc.

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 confi gured. Grayed-out options cannot be confi gured. Options in blue can be
confi 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>, <F10>, <Enter>, <ESC>, ar­row keys, etc.

Note: Options printed in Bold are default settings.

How To Change the Confi guration Data

The confi 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.

This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference only:

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 confi 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 confi 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 ‘Tem­perature Tolerance’ has been reached (or has been exceeded) and may activate
an overheat alarm. The system may shut down if it continues for a long period to
prevent damage to the CPU.

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.

X8DAH+/X8DAH+-F User’s Manual

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 each CPU is embedded by unique temperature
information that the motherboard can read. This ‘Temperature Threshold’ or
‘Temperature Tolerance’ has been assigned at the factory and is the baseline on
which the motherboard takes action during different CPU temperature conditions
(i.e., by increasing CPU Fan speed, triggering the Overheat Alarm, etc). Since
CPUs can have different ‘Temperature Tolerances’, the installed CPU can now
send information to the motherboard what its ‘Temperature Tolerance’ is, and not
the other way around. This results 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., 25

o

C).

The information provided above is for your reference only. For more information
on thermal management, please refer to Intel’s Web site at www.Intel.com.

System Temperature: The system te mperat ure will b e displayed ( in degre es in
Celsiu s and Fahrenh eit) as it is detec ted by the BI OS.

Fan Speed Readings

This feature displays the fan speed readings from Fan1 through Fan8.

Fan Speed Control Modes

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

Select Workstation if your system is used as a Workstation. Select Server if your
system is used as a Server. Select Disabled to disable the fan speed control func­tion and allow the onboard fans to constantly run at full speed. The Options are:

Full Speed, Server, Workstation/Desktop, and Server Quiet.

4-7 BIOS Recovery

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. This is to avoid possible boot failure.

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

An AMIBIOS fl 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 code, including
memory detection and recovery code to be used to fl ash a new BIOS image if the
original BIOS Image is corrupted. When the system is powered on, the boot sector
code executes fi rst. Once it is completed, the main BIOS code will continue with
system initialization and complete the bootup process.

Notes: BIOS Recovery described below is used when the main BIOS
block crashes. However, when the BIOS Boot sector crashes, you will need
to send the motherboard back to Supermicro for RMA repairs.

4.7.1 Boot Sector Recovery from a USB Device

This feature allows the user to recover a BIOS image using a USB device without
additional utilities needed. A user can download the BIOS image into a USB fl ash
device, and name the fi le "SUPER.ROM" for the recovery process to load the fi le.
A USB fl ash device such as a USB Flash Drive, a USB CDROM or a USB CDRW
device can be used for this purpose,

Insert the USB device that contains the new BIOS image (the ROM fi les) 1.
saved in a root directory into your USB drive.

While turning the power on, press and hold <Ctrl> and <Home> at the same 2.
time until the USB Access LED Indicator comes on. This might take a few
seconds.

Once the USB drive LED is on, release the <Ctrl> and <Home> keys. 3.
AMIBIOS will issue beep codes to indicate that the BIOS ROM fi le is being
updated.

When BIOS fl ashing is completed, the computer will reboot. Do not interrupt 4.
the fl ashing process until it is completed.

4-29

X8DAH+/X8DAH+-F User’s Manual

4.7.2 Boot Sector Recovery from an IDE CD-ROM

This process is almost identical to the process of Boot Sector Recovery from a USB
device, except that the BIOS image fi le is loaded from a CD-ROM. Use a CD-R or
CD-RW drive to burn a CD with the BIOS image fi le in it, and name the fi le "SUPER.
ROM" for the recovery process to load the fi le.

4.7.3 Boot Sector Recovery from a Serial Port ("Serial
Flash")

This process, also known as "Serial Flash," allows the user to use a serial port to
load a BIOS image for Boot Sector recovery . This feature is usually used for embed­ded systems that rely on a serial port for remote access and debugging.

Requirements

In order to use Serial Flash for Boot Sector Recovery, you will need to meet the
following requirements.

The "Target system," the system that needs BIOS updates, must have a serial

•

port and "Serial Flash" support embedded in the BIOS image fi le.
The "Host system" should also have a serial port and a terminal program that

•

supports XModem Transfer protocol (Hyper Terminal for the Windows operating
systems, and minicom for Linux/FreeSBD, etc.).

A Null_modem serial cable

•

How to use Serial Flash for Boot Sector Recovery

Connect a Null_modem serial cable between the target system and the host 1.
system that runs the terminal program.

Make sure that the new BIOS Image fi le is accessible for the host system.2.

Start the terminal program on the host system and create a new connection. 3.
Use the following communication parameters for the new connection.

Bits per second: 115200 bits/sec.

•

Data Bits: 8•
Parity: None•
Stop Bit: 1•
Flow Control: None•

5. Following the instructions given on the screen to update the BIOS. These
instructions are also shown below.

a. At the prompt, press the <SpaceBar> to update the BIOS.
b. When asked to confi rm BIOS updating, press <y> to confi rm BIOS

updates.

c. Press <y> again to begin fl ashing BIOS remotely.

Note: Be sure to complete Steps a~c above quickly because
you have a second or less to do so.

6. Once you've completed the instructions given, a screen will display to indicate
that remote fl ashing is starting and the new BIOS fi le is being uploaded.

7. To use Hyper Terminal to transfer the XModem protocol by using the "Send
File" dialog under the "Transfer" menu, follow the instructions below to com­plete XModem transfers.

a. Select the "Transfer" menu and enter <Send>.

b. Specify the location of the ROM fi le and select the proper protocol (XMo-

dem).

c. Press <Send> to start ROM File extraction. (See the picture below.)

X8DAH+/X8DAH+-F User’s Manual

d. Once the ROM fi le extraction is completed, the message: "New BIOS re-

ceived OK" will display.

8. Once remote BIOS fl ash is completed, the system will reboot.

Note: AMIBIOS Serial Flash will work with any terminal communications
program that supports VT-100 and XModem protocols, including protocols
designed for GNU/LINUX & BSD operating systems such as minicom. It
is recommended that the terminal program be confi gured to use the 'CR/
LF' style of line termination.

Appendix A: BIOS POST Error Codes

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
the boot-up process. The error messages normally appear on the screen.

Fatal errors are those which will not allow the system to continue the boot-up
procedure. If a fatal error occurs, 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.

C-2 Confi guring Supero Doctor III

The Supero Doctor III program is a Web-base management tool that supports
remote management capability. It includes Remote and Local Management tools.
The local management is called the SD III Client. The Supero Doctor III program
included on the CDROM that came with your motherboard allows you to monitor
the environment and operations of your system. Supero Doctor III displays crucial
system information such as CPU temperature, system voltages and fan status. See
the Figure below for a display of the Supero Doctor III interface.

Note: 1 The default user name and password are ADMIN.
Note 2: In the Windows OS environment, the Supero Doctor III settings

take precedence over the BIOS settings. When fi rst installed, Supero Doc-
tor III adopts the temperature threshold settings previously set in 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 BIOS.
