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.  
1-7  
 
 
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.  
1-8  
 
             
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.  
1-9  
 
           
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).

Installation  
2-1 Static-Sensitive Devices  
Electrostatic Discharge (ESD) can damage electronic components. To prevent damage  
to your system board, it is important to handle it very carefully. The following measures  
are generally sufficient 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 specified by the  
manufacturer. 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.  
Installation Procedure  
Follow the procedures as listed below to install the motherboard into a chassis.  
1. Install the processor(s) and the heatsink(s).  
2. Install the motherboard in the chassis.  
3. Install the memory and add-on cards.  
4. Finally, connect the cables and install the drivers.

2-2 Processor and Heatsink Installation  
Follow the procedures in this section for installing the processor and heatsink into the  
H8DMT Serverboard.  
WARNING: Exercise extreme caution when handling and installing the  
processor. Always connect the power cord last and always remove it before  
adding, removing or changing any hardware components.  
Installing the Processors  
1. Begin by removing the cover plate 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.  
Figure 2-1. Removing the CPU Cover Plate  
2. Use your thumb and your index finger 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. Align pin 1 of the  
CPU with pin 1 of the socket.  
Figure 2-2. Aligning the CPU with Socket  
2-2  
 
 
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).  
NOTE: In single and dual-CPU configurations, 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 configurations.

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.

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  
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.  
2-17  
 
     
H8DMT/H8DMT-IBX/H8DMT-F/H8DMT-IBXF User’s Manual

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  
the http://www.supermicro.com web site for more details.  
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  
required to implement the ACPI features on the Serverboard.

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.

You can edit this field 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 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.
