Chapter 1: Introduction
1-3 Chipset Overview
The H8DMT+/H8DMT-INF+ motherboard is based on the nVidia MCP55-V Pro
chipset. The nVidia MCP55 Pro functions as Media and Communications Proces-
sor (MCP). Controllers for the system memory are integrated directly into AMD
Opteron processors.
MCP55-V Pro Media and Communications Processor
The MCP55-V Pro is a single-chip, high-performance HyperTransport peripheral
controller. It includes a 28-lane PCI Express interface, an AMD Opteron 16-bit Hyper
Transport interface link, a four-port Serial ATA interface, a dual-port Gb Ethernet
interface and a six-port USB 2.0 interface. This hub connects directly to the CPU.
HyperTransport Technology
HyperTransport technology is a high-speed, low latency point to point link that was
designed to increase the communication speed by a factor of up to 48x between
integrated circuits. This is done partly by reducing the number of buses in the
chipset to reduce bottlenecks and by enabling a more effi cient use of memory
in multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.
1-9
H8DMT+/H8DMT-INF+ User’s Manual
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the H8DMT+/H8DMT-
INF+. The motherboard has an onboard System Hardware Monitor chip that sup-
ports PC health monitoring.
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. Once a
voltage becomes unstable, it will give a warning or send an error message to the
screen. Users can adjust the voltage thresholds to defi ne the sensitivity of the volt-
age monitor. Real time readings of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware/Software Speed Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by thermal management via BIOS.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat/Fan Fail warning
function in the BIOS. This allows the user to defi ne an overheat temperature. When
this temperature is exceeded or when a fan failure occurs, the Overheat/Fan Fail
warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to 80A
and auto-sense voltage IDs ranging from 0.8 V to 1.55V. This will allow the regulator
to run cooler and thus make the system more stable.
1-5 Power Confi guration Settings
This section describes the features of your motherboard that deal with power and
power settings.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for a PC that is always on but appears
to be off and responds immediately to user or other requests.
1-10
Chapter 1: Introduction
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.
BIOS Support for USB Keyboard
If a USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
Main Switch Override Mechanism
The power button can function as a system suspend button. When the user de-
presses the power button, the system will enter a SoftOff state. The monitor will be
suspended and the hard drive will spin down. Depressing the power button again
will cause the whole system to wake-up. During the SoftOff state, the power sup-
ply 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 depress and hold the
power button for 4 seconds. The power will turn off and no power will be provided
to the motherboard.
Wake-On-LAN (WOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and access
tracking can occur after hours and on weekends so that daily LAN traffi c 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. Wake-On-LAN must be enabled in BIOS.
Wake-On-Ring Header (WOR)
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state.
1-11
H8DMT+/H8DMT-INF+ User’s Manual
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 H8DMT+/H8DMT-INF+ requires the use of proprietary power supplies. Please
refer to the pinout information for the power connectors in Section 6 of Chapter 2
for detailed information on power requirements.
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.
Warning: To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.
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 provides two high-speed, 16550 compatible serial communication
ports (UARTs), one of which supports serial infrared communication. Each UART in-
cludes 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), Bi-directional Printer
Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
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-
ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can be fl exibly adjusted
to meet ISA PnP requirements, which support ACPI and APM (Advanced Power
Management).

2-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-
age to your system board, it is important to handle it very carefully. The following
measures are generally suffi 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 CMOS onboard battery as specifi ed by the manu-
•
facturer. Do not install the CMOS onboard battery upside down, which may
result in a possible explosion.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.

Installing the Processors
Begin by removing the cover plate
1.
that protects the CPU. Lift the lever
on the CPU socket until it points
straight up. With the lever raised, lift
open the silver CPU retention plate.
Triangles
Use your thumb and your index
2.
fi nger to hold the CPU. Locate and
align pin 1 of the CPU socket with
pin 1 of the CPU. Both are marked
with a triangle.
2-2
Align pin 1 of the CPU with pin 1 of
3.
the socket. Once aligned, carefully
place the CPU into the socket. Do
not drop the CPU on the socket,
move the CPU horizontally or
vertically or rub the CPU against
the socket or against any pins of
the socket, which may damage the
CPU and/or the socket.
With the CPU inserted into the
4.
socket, inspect the four corners
of the CPU to make sure that it is
properly installed and fl ush with the
socket. Then, gently lower the sil-
ver CPU retention plate into place.
Chapter 2: Installation
Carefully press the CPU socket le-
5.
ver down until it locks into its reten-
tion tab. For a dual-CPU system,
repeat these steps to install another
CPU into the CPU#2 socket (and
into CPU#2, #3 and #4 sockets for
a quad-CPU confi guration).
Note: in single and dual-CPU confi gura-
tions, memory must be installed in the
DIMM slots associated with the installed
CPU(s). Memory is limited to a maximum
of 32 for single CPU and 64 GB for dual
CPU confi gurations.
Installing the Heatsinks
We recommend the use of active type heatsinks (except for 1U systems). Use any
onboard fan header for the CPU's heatsink fan. To install the heatsink, please follow
the installation instructions included with your heatsink package (not included).

H8DMT+/H8DMT-INF+ User's Manual
2-3 Mounting the Motherboard into a Chassis
All motherboards have standard mounting holes to fi t different types of chassis.
Make sure that the locations of all the mounting holes for both the motherboard
and the chassis match. Although a chassis may have both plastic and metal
mounting fasteners, 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.
Check the Compatibility of the Motherboard Ports and the I/O Shield
The H8DMT+/H8DMT-INF+ motherboard requires a chassis that can support
1.
a board of 16.64" x 6.8" in size. It was designed to be used in a Supermicro
1U Twin system.
Make sure that the I/O ports on the motherboard align with their respective
2.
holes in the I/O shield at the rear of the chassis.
Mounting the Motherboard onto the Tray in the Chassis
Carefully mount the motherboard onto the motherboard tray by aligning the
1.
motherboard mounting holes with the raised metal standoffs in the tray.
Insert screws into all the mounting holes in the motherboard that line up with
2.
the standoffs.
Then use a screwdriver to secure the motherboard to the mainboard tray
3.
- tighten until just snug (if too tight you might strip the threads). Metal screws
provide an electrical contact to the motherboard ground to provide a continu-
ous ground for the system.
Exercise extreme caution when installing or removing memory mod-
!
ules to prevent any possible damage.
2-4 Installing Memory
Installing Memory
Insert each memory module vertically into its slot, paying attention to the
1.

Chapter 2: Installation
Gently press down on the memory module until it snaps into place.
3.
With two CPUs installed, repeat step 2 to populate the CPU2 DIMM slots.
4.
Always install pairs of DIMMs to both CPU DIMM slots for more effi cient
operation.
Note: 256 MB, 512 MB, 1 GB, 2 GB and 4 GB memory modules are supported.
It is highly recommended that you remove the power cord from the system before
installing or changing memory modules. Please refer to our web site for memory
that has been tested on the H8DMT+/H8DMT-INF+.
Support
The H8DMT+/H8DMT-INF+ supports single or dual-channel, DDR2-667/533/400
registered ECC SDRAM. Only interleaved memory is supported, so you must
populate two DIMM slots at a time (see procedure above).
Populating two adjacent slots at a time with memory modules of the same size and
type will result in interleaved (128-bit) memory, which is faster than non-interleaved
(64-bit) memory. Note: Due to a CPU limitation, fully populating DIMM slots with
DDR2-667 will pull the speed down to 533 MHz. Please see our web site for pos-
sible updates to this limitation.
Maximum Memory
64 GB of DDR2-667/533/400 registered ECC SDRAM.

2-10 Enabling SATA RAID
Now that the hardware is set up, you must install the operating system and the
SATA RAID drivers, if you wish to use RAID with your SATA drives. The installation
procedure differs depending on whether you wish to have the operating system
installed on a RAID array or on a separate non-RAID drive. See the instructions
below for details.
Serial ATA (SATA)
Serial ATA (SATA) is a physical storage interface that employs a single cable with a
minimum of four wires to create a point-to-point connection between devices. This
connection is a serial link that supports a SATA transfer rate from 150 MBps. The
serial cables used in SATA are thinner than the traditional cables used in Parallel
ATA (PATA) and can extend up to one meter in length, compared to only 40 cm for
PATA cab les. Overall, SATA provides better functionality than PATA .
Installing the OS/SATA Driver
Before installing the OS (operating system) and SATA RAID driver, you must de-
cide if you wish to have the operating system installed as part of a bootable RAID
array or installed to a separate non-RAID hard drive. If on a separate drive, you
may install the driver either during or after the OS installation. If you wish to have
the OS on a SATA RAID array, you must follow the procedure below and install the
driver during the OS installation.
Building a Driver Diskette
You must fi rst build a driver diskette from the Supermicro CD-ROM that was included
with the system. (You will have to create this disk on a computer that is already
running and with the OS installed.) Insert the CD into your CD-ROM drive and start
the system. A display as shown in Figure 2-4 will appear. Click on the icon labeled
"Build Driver Diskettes and Manuals" and follow the instructions to create a fl oppy
disk with the driver on it. Once it's been created, remove the fl oppy and insert the
installation CD for the Windows Operating System you wish to install into the CD-
ROM drive of the new system you are about to confi gure.

include in the RAID array and the mode and type of RAID. Two main windows are
shown in the utility. The "Free Disks" window on the left will list all available drives.
Use the arrow keys to select and move drives to the window on the right, which
lists all drives that are to become part of the RAID array.
Once you have fi nished selecting the drives and type of RAID you wish to use for
your RAID array, press the <F7> key. You will be prompted to verify your choice; if
you want to continue with your choices, select "Yes". Note that selecting "Yes" will
clear all previous data from the drives you selected to be a part of the array. You
are then given the choice of making the RAID array bootable by pressing the the
<B> key. After you have fi nshed, press the <Ctrl> and <X> keys simultaneously.
Installing the OS and Drivers
With the Windows OS installation CD in the CD-ROM drive, restart the system.
When you see the prompt, hit the <F6> key to enter Windows setup. Eventually a
blue screen will appear with a message that begins "Windows could not determine
the type of one or more storage devices . . ." When you see the screen, hit the <S>
key to "Specify Additional Device", then insert the driver diskette you just created
2-17

into the fl oppy drive. Highlight "Manufuacturer Supplied Hardware Support Disk"
and hit the <Enter> key. Highlight the fi rst "nVidia RAID" driver shown and press
the <Enter> key to install it. Soon a similar blue screen will appear again. Again hit
the <S> key, then highlight the second item, "nForce Storage Controller" and press
the <Enter> key, then <Enter> again to continue with the Windows setup.
2-11 Installing Drivers
The CD that came bundled with the system contains drivers, some of which must
be installed, such as the chipset driver. After inserting this CD into your CD-ROM
drive, the display shown in Figure 2-4 should appear. (If this display does not appear,
click on the My Computer icon and then on the icon representing your CD-ROM
drive. Finally, double click on the S "Setup" icon.)

image (xxx.rom) fi les. Copy these fi les to a bootable fl oppy disk, insert the disk
into drive A and reboot the system. At the DOS prompt after rebooting, enter the
command "fl ash" (without quotation marks) then type in the BIOS fi le that you want

Question: What's on the CD that came with my motherboard?
Answer: The supplied compact disc has quite a few drivers and programs that will
greatly enhance your system. We recommend that you review the CD and install the
applications you need. Applications on the CD include chipset drivers for Windows
and security and audio drivers.
Question: Why can't I turn off the power using the momentary power on/off
switch?
Answer: The instant power off function is controlled in BIOS by the Power But-
ton Mode setting. When the On/Off feature is enabled, the motherboard will have
instant off capabilities as long as the BIOS has control of the system. When the
Standby or Suspend feature is enabled or when the BIOS is not in control such
as during memory count (the fi rst screen that appears when the system is turned
on), the momentary on/off switch must be held for more than four seconds to shut
down the system. This feature is required to implement the ACPI features on the
motherboard.

BIOS
4-1 Introduction
This chapter describes the AMIBIOS™ Setup utility for the H8DMT+/H8DMT-INF+.
The AMI ROM BIOS is stored in a fl ash chip and can be easily upgraded using a
fl oppy 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 our web site for any changes to BIOS that may not be refl ected
in this manual.
Starting the Setup Utility
To enter the BIOS Setup Utility, hit the <Delete> key while the system is booting-up.
(In most cases, the <Delete> key is used to invoke the 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 screen has two main frames. The left frame displays all the options
that can be confi gured. “Grayed-out” options cannot be confi gured. The right frame
displays the key legend. Above the key legend is an area reserved for a text mes-
sage. When an option is selected in the left frame, it is highlighted in white. Often
a text message will accompany it. (Note that BIOS has default text messages built
in. We retain the option to include, omit, or change any of these text messages.)
Settings printed in Bold are the default values.
A "
" indicates a submenu. Highlighting such an item and pressing the <Enter>
key will open the list of settings within that submenu.
The BIOS setup utility uses a key-based navigation system called hot keys. Most
of these hot keys (<F1>, <F10>, <Enter>, <ESC>, <Arrow> keys, etc.) can be used
at any time during the setup navigation process.

4-2 Main Menu
When you fi rst enter AMI BIOS Setup Utility, you will see the Main Menu screen.
You can always return to the Main Menu by selecting the Main tab on the top of
the screen with the arrow keys.
The Main Menu screen provides you with a system overview, which includes the
version, built date and ID of the AMIBIOS, the type, speed and number of the pro-
cessors in the system and the amount of memory installed in the system.
System Time/System Date
You can edit this fi eld to change the system time and date. Highlight System Time
or System Date using the <Arrow> keys. Enter new values through the keyboard.
Press the <Tab> key or the <Arrow> keys to move between fi elds. The date must
be entered in DAY/MM/DD/YYYY format. The time is entered in HH:MM:SS format.
Please note that time is in a 24-hour format. For example, 5:30 A.M. appears as
05:30:00 and 5:30 P.M. as 17:30:00.

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 pro-
cedure. 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 (on the following page) correspond to the number
of beeps for the corresponding error. All errors listed, with the exception of Beep
