Chapter 1: Introduction

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 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 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.

1-5 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.

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 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 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

1-6 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.

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.

1-7 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-

1-13

X8DAH+/X8DAH+-F User's Manual

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

1-8 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 Cores, 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 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.

Fan Headers

This motherboard has six chassis/sys­tem fan headers (Fan 1 to Fan6) and
two CPU fans (CPU1 Fan/CPU2 Fan)
on the motherboard. In addition, I-Fan
1 and I-Fan 2 are available on a R 2.0
or newer version motherboard for IOH­36D cooling. The 4-pin fans headers are
backward compatible with the traditional
3-pin fans. However, fan speed control is
available for 4-pin fans only via Hardware
Monitoring in the Advanced Setting in the
BIOS. See the table on the right for pin

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

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.

Chapter 4: AMI BIOS

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.
Note 2: For AMI BIOS Recovery, please refer to the AMI BIOS Recovery

Instructions posted on our website at http://www.supermicro.com/support/
manuals/.

manufacturer to give the CPU and system fans additional time needed for CPU
and system cooling. In both the alarms above, please take immediate action
as shown below.

CPU 1 Temperature/CPU 2 Temperature/IOH 1 Temperature/IOH 2
Temperature/System Temperature

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

CPU 1 Temperature/CPU 2 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.

4-17

X8DAH+/X8DAH+-F User’s Manual

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.

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 website at www.Intel.com.

system cooling. Select "Full Speed/FS" to allow the onboard fans to run at full
speed for maximum cooling. The FS setting is recommended for special system
confi guration or debugging. Select "Performance/PF" for better system cooling. The
PF setting is recommended for high-power-consuming and high-density systems.
Select "Balanced/BL" for the onboard fans to run at a speed that will balance the
needs between system cooling and power saving. The BL setting is recommended
for regular systems with normal hardware confi gurations. Select "Energy Saving/ES"
for best power effi ciency and maximum quietness. The Options are: Full Speed/FS,
Performance/PF, Balanced/BL, and Energy Saving/ES.

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 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-based 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.
