Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWN+
motherboard provides the performance and feature set required for quad-processor or dual-processor-based high-end systems with confi guration options
optimized for complex storage platforms. The 5400 chipset supports single or
dual Intel Quad-Core/Dual-Core Xeon 5400 Series/5300LV Series/5200 Series/
5100LV Series processor with front side bus speeds of up to 1.6 GHz. The chipset
consists of the 5400 Memory Controller Hub (MCH) for the host bridge and the
631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2-ESB2) for the
I/O subsystem.
The Intel 5400 MCH (North Bridge)
The 5400 MCH (North Bridge) provides two FSB processing interfaces, four fully
buffered (FBD) DIMM memory channels, PCI-Express bus interfaces configurable
to form x8 or x16 ports, an EB2 South Bridge Interface (ESI) and SMBus Interfaces
for system management, and DIMM Serial Presence Detect (SPD). The peak
bandwidth for each FBD channel is 8 GB/s for DDR2 800/667 FBD memory, giving
a total memory size of 128 MB for 4 FBD channels. The PCI-Express interfaces
can be configured to form x8 or x16 ports that can operate up to Gen-2 speeds
in x16 configuration for enhanced graphics applications.
The Intel 631xESB/632x ESB I/O Controller Hub-ESB2 (South Bridge)
The 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2) integrates
an Ultra ATA 100 Controller, six Serial ATA host controller ports, one EHCI host
controller, six external USB 2.0 ports, an LPC interface controller, and a flash
BIOS interface controller. Additionally, the ESB 2 chip also contains a PCI interface
controller, Azalia/'97 digital controller, integrated LAN controller, an ASF controller and an ESI for communication with the MCH. The Intel ESB2 offers the data
buffering and interface arbitration capabilities required for a high-end system to
constantly operate efficiently and maintain peak performance.

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 X7DWN+. All have
an onboard System Hardware Monitor chip that supports PC health monitoring.
Onboard Voltage Monitors for CPU Core, Chipset Voltage,
Memory Voltage, +1.8V, +5V, +3.3V, +3.3V Standby, +5V Standby,
+12V, −12V and VBatt
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 define 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 userdefined 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.
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.
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 define an overheat temperature. When the
1-10
Chapter 1: Introduction
CPU temperature passes this threshold, 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
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 configure
Supero Doctor to provide you with warnings when the system temperature, CPU
temperatures, voltages and fan speeds go beyond a pre-defined range.
1-5
ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specifi cation defines a flexible 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 configuration 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.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can
only be used with an ATX 2.01 (or above) compliant power supply.
1-11
X7DWN+ User's Manual
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN traffic is kept
to a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.
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 X7DWN+ can accommodate 24-pin ATX power supplies. Although most
power supplies generally meet the specifications required by the CPU, some are
inadequate. In addition, the 12V 4-pin and the 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.
NOTE: The + 12V 8-pin CPU Power Connector (JPW3) is also required to
support Intel 64-bit CPUs. Failure to provide this extra power will result
in CPU PWR Failure. See Section 2-5 for details on connecting the power
supply.
It is strongly recommended that you use a high quality power supply that meets
ATX power supply Specification 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 filter 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 floppy 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 floppy 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
1-12
Chapter 1: Introduction
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 supports one PC-compatible printer port (SPP), Bidirectional Printer
Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power management through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

• 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 specifi ed by the
manufacturer. Do not install the onboard battery upside down to avoid possible
explosion.

Installing DIMMs
Note: Check the Supermicro web site for recommended memory modules.
CAUTION
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage. Also note that the
memory is interleaved to improve performance (see step 1).
DIMM Installation (See Figure 2-2)
1. Insert the desired number of DIMMs into the memory slots, starting with DIMM
#1A. The memory scheme is interleaved, so you must install (a) pair(s) of
modules of the same type and same speed at a time, beginning with Bank
1, Bank 2 and so on. For optimal memory performance, please install four
modules at a time with the maximum of 16 modules. (*See the Memory
Installation Table Below.)
2. Insert each DIMM module vertically into its slot. Pay attention to the notch along
the bottom of the module to prevent inserting the DIMM module incorrectly.
3. Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules (see step 1 above).
Memory Support
The X7DWN+ supports up to 128 GB fully buffered (FBD) ECC DDR 2 800/667/533

Two G-bit Ethernet ports are located
GLAN1
GLAN2
at JLAN1 and JLAN2 on the I/O
backplane. These ports accept RJ45
type cables.
Power LED/Speaker
On the JD1 header, pins 1-3 are
used for power LED indication, and
pins 4-7 are for the speaker. See
the table on the right for speaker
pin defi nitions. Note: The speaker
connector pins (4-7) are for use with
an external speaker. If you wish to
use the onboard speaker, you should
close pins 6-7 with a jumper.

pages for jumper locations.
Note: On two pin jumpers, "Closed"
means the jumper is on and "Open"
means the jumper is off the pins.

CMOS Clear
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, remove the AC power cord and then short JBT1 to clear CMOS.
Watch Dog Enable/Disable
Watch Dog (JWD) is a system monitor that can
reboot the system when a software application
hangs. Close Pins 1-2 to reset the system if an
application hangs. Close Pins 2-3 to generate a
non-maskable interrupt signal for the application
that hangs. See the table on the right for jumper
settings. Watch Dog must also be enabled in the
BIOS.

Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the X7DWN+. The
Phoenix ROM BIOS is stored in a flash chip and can be easily upgraded using a
floppy 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 Supermicro web site <http://www.supermicro.com> for any
changes to the BIOS that may not be reflected 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
provides power to the CMOS Logic, enabling it to retain system parameters. When
the computer is powered on, the computer is configured with the values stored in
the CMOS Logic by the system BIOS, which gains control at boot up.
How To Change the Configuration 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.
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 descriptions are given for each parameter setting in the Setup utility.
Warning: Do not shut down or reset the system while updating BIOS
to prevent possible boot failure.

Previous POST did not complete successfully. POST loads default values and offers
to run Setup. If the failure was caused by incorrect values and they are not corrected,
the next boot will likely fail. On systems with control of wait states, improper Setup
settings can also terminate POST and cause this error on the next boot. Run Setup
and verify that the waitstate configuration is correct. This error is cleared the next
time the system is booted.

This section lists the POST (Power On Self Test) codes for the Phoenix BIOS. POST
codes are divided into two categories: recoverable and terminal.
Recoverable POST Errors
When a recoverable type of error occurs during POST, the BIOS will display an
POST code that describes the problem. BIOS may also issue one of the following
beep codes:
1 long and two short beeps - video configuration error
1 repetitive long beep - no memory detected
Terminal POST Errors
If a terminal type of error occurs, BIOS will shut down the system. Before doing
so, BIOS will write the error to port 80h, attempt to initialize video and write the

* If the BIOS detects errors on 2C, 2E, or 30 (base 512K RAM error), it displays an
additional word-bitmap (xxxx) indicating the address line or bits that have failed. For
example, “2C 0002” means address line 1 (bit one set) has failed. “2E 1020" means
data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also
sends the bitmap to the port-80 LED display. It first displays the checkpoint code,

Serial ATA (SATA)
Serial ATA (SATA) is a physical storage interface that uses a single cable with a
minimum of four wires to create a point-to-point connection between devices. It
is a serial link, which supports transfer rates up to 3.0 Gbps. Because the serial
cables used in SATA are thinner than the traditional cables used in Parallel ATA
(PATA), SATA systems have better airflow and can be installed in smaller chassis
than Parallel ATA. In addition, the cables used in PATA are limited to a length of
40cm, while Serial ATA cables can be up to one meter in length. Overall, SATA
provides better functionality than PATA.
Introduction to the Intel ESB2 Serial RAID
Located in the South Bridge of the 5400 chipset, the I/O Controller Hub (ESB2)
provides the I/O subsystem with access to the rest of the system. It supports
an 1-channel UltraATA/100 Bus Master IDE controller (PATA) and six Serial ATA
(SATA) ports. The ESB2 supports the following PATA and SATA device configurations: Legacy mode and Native mode.

X7DWN+ User's Manual
The Intel HostRAID Configurations
The following types of Intel's HostRAID configurations are supported:
RAID 0 (Data Striping): this writes data in parallel, interleaved ("striped") sections
of two hard drives. Data transfer rate is doubled over using a single disk.
RAID 1 (Data Mirroring): an identical data image from one drive is copied to another drive. The second drive must be the same size or larger than the first drive.
RAID 10 (Striping & Mirroring): RAID 0 and 1 schemes are combined (without
parity information) to get the benefits of both.
RAID 5: both data and parity information are striped and mirrored across three
or more hard drives.
The Intel Matrix Storage
The Intel Matrix Storage, supported by the ESB2, allows the user to create RAID
0, RAID 1, RAID 10 and RAID 5 sets by using only six identical hard disk drives.
The Intel Matrix Storage Technology creates two partitions on each hard disk drive
and generate a virtual RAID 0, RAID 1, RAID 10 and RAID 5 sets. It also allows
you the change the HDD partition size without any data.

The Adaptec Embedded Serial ATA with HostRAID Controller
Driver
The Adaptec Embedded Serial ATA RAID Controller adds SATA/RAID functionality and performance enhancements to a motherboard. RAID striping (RAID 0)
allows data to be written across multiple drives, greatly improving hard disk I/O
performance. RAID mirroring (RAID 1) allows data to be simultaneously written
to two drives, improving data security even if a single hard disk fails. A Stripe of
Mirrors (RAID 10) provides multiple RAID 1 mirrors and a RAID 0 stripe, maximizing data security and system efficiency. By incorporating the Adaptec Embedded
Serial ATA into the motherboard design, Supermicro's X7DWN+ offers the user
the benefits of SATARAID without the high costs associated with hardware RAID
applications.

Configuring 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 first installed, Supero Doctor 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.
