The H8DMT/H8DMT-IBX/H8DMT-F/H8DMT-IBXF Serverboard is based on the nVidia
MCP55 Pro Chipset, which functions as a Media and Communications Processor
(MCP). Controllers for the system memory are integrated directly into Opteron
processors.

H8DMT/H8DMT-IBX/H8DMT-F/H8DMT-IBXF User’s Manual
nVidia MCP55 Pro Chipset Media and Communications
Processor
The nVidia MCP55 Pro Chipset 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, a dual ATA133 bus master interface and a 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 efficient use of memory in multi-processor
systems. The end result is a significant increase in bandwidth within the chipset.
1-6 PC Health Monitoring
This section describes the PC health monitoring features of the H8DMT/H8DMT-IBX/
H8DMT-F/H8DMT-IBXF serverboard. The serverboard has an onboard System
Hardware Monitor chip that supports 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 define the sensitivity of the voltage 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 define 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.

Chapter 1: Introduction
1-7 Power Configuration 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.
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
When an ATX power supply is used, the power button can function as a system suspend
button. When the user depresses 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 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 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 defined 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 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. Wake-On-LAN
must be enabled in BIOS. Note that Wake-On-LAN can only be used with an ATX 2.01
(or above) compliant power supply.

H8DMT/H8DMT-IBX/H8DMT-F/H8DMT-IBXF User’s Manual
1-8 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 accommodates 12V proprietary power supplies. Although most power
supplies generally meet the specifications required by the CPU, some are inadequate. A
2 amp current supply on a 5V Standby rail is strongly recommended.
It is strongly recommended that you use a high quality power supply that meets 12V
ATX power supply Specification 1.1 or above. 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.
WARNING: To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.
1-9 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 provides two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. 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
250K, 500K, 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 Configuration and
Power Interface), which includes support of legacy and ACPI power management
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 flexibly adjusted to
meet ISA PnP requirements, which support ACPI and APM (Advanced Power
Management).

Chapter 2: Installation
3. 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.
Figure 2-3. Placing the CPU into the Socket
4. With the CPU inserted into the socket, inspect the four corners of the CPU to make
sure that it is properly installed and flush with the socket. Then, gently lower the
silver CPU retention plate into place.
Figure 2-4. Inspecting the CPU Installation
5. Carefully press the CPU socket lever down until it locks into its retention 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 configuration).

Figure 2-5. Secure the CPU with Socket Lever
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).
2-3 Mounting the Mainboard into a Chassis
All Serverboards have standard mounting holes to fit different types of chassis. Make
sure that the locations of all the mounting holes for both the Serverboard and the
chassis match. Although a chassis may have both plastic and metal mounting fasteners,
metal ones are highly recommended because they ground the Serverboard to the
chassis. Make sure that the metal standoffs click in or are screwed in tightly.
Checking the Compatibility of the Mainboard Ports and the I/O Shield
1. The H8DMT Serverboard requires a chassis that can support a board of 16.4" x 6.5"
in size. It was designed to be used in a Supermicro 1U Twin system.
2. Make sure that the I/O ports on the Serverboard align with their respective holes in
the I/O shield at the rear of the chassis.
Mounting the Mainboard onto the Tray in the Chassis
1. Carefully mount the Serverboard onto the motherboard tray by aligning the
motherboard mounting holes with the raised metal standoffs in the tray.
2. Insert screws into all the mounting holes in the Serverboard that line up with the
standoffs.
3. Then use a screwdriver to secure the Serverboard to the mainboard tray - tighten
until just snug (if too tight you might strip the threads). Metal screws provide an
electrical contact to the Serverboard ground to provide a continuous ground for the
system.

Support
The H8DMT/H8DMT-IBX/H8DMT-F/H8DMT-IBXF Serverboards support single or
dual-channel, DDR2-800/667/533 registered ECC SDRAM.
Only interleaved memory is supported, so you must populate two DIMM slots at a time.
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.

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
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 cables.
Overall, SATA provides better functionality than PATA.

3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The H8DMT supports up to 32 GB of DDR2-800/667/533 registered ECC
SDRAM (or 16 GB with a single CPU installed). Memory must be installed in an
interleaved configuration only. See Section 2-4 for details on installing memory. Refer to
Question: How do I update my BIOS?
Answer: It is recommended that you not upgrade your BIOS if you are not experiencing
problems with your system. Updated BIOS files are located on our web site. Please
check our BIOS warning message and the information on how to update your BIOS on
our web site. Also, check the current BIOS revision and make sure it is newer than your
current BIOS before downloading.
Select your motherboard model on the web page and download the corresponding
BIOS file to your computer. Unzip the BIOS update file, in which you will find the
readme.txt (flash instructions), the afudos.exe (BIOS flash utility) and the BIOS image
(xxx.rom) files. Copy these files to a bootable floppy disk, insert the disk into drive A and
reboot the system. At the DOS prompt after rebooting, enter the command "flash"
(without quotation marks) then type in the BIOS file that you want to update with
(xxxx.rom).
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 Button 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 first 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

BIOS
4-1 Introduction
This chapter describes the AMIBIOS™ Setup utility for the H8DMT/H8DMT-IBX/
H8DMT-F/H8DMT-IBXF Serverboards. The AMI 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 our web site for any changes to BIOS that may
not be reflected in this manual.
4-2 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 configured. “Grayed-out” options cannot be configured. 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 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.
4-3 Main Menu
When you first 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
processors in the system and the amount of memory installed in the system.

System Time/System Date
System Date using the <ARROW> keys. Enter new values through the keyboard. Press
the <TAB> key or the <ARROW> keys to move between fields. 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

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 (on the following page) correspond to the number of
beeps for the corresponding error. All errors listed, with the exception of Beep Code 8,
are fatal errors.
