Chapter 1: Introduction

1-5 Chipset Overview

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.

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.

1-9

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

1-10

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.

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).

WARNING: To prevent the possibility of explosion, do not use the wrong type of

onboard CMOS battery or install it upside down.

2-2 Processor and Heatsink Installation

Follow the procedures in this section for installing the processor and heatsink into the

H8DMT Serverboard.

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.

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.

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.

Figure 2-1. Removing the CPU Cover Plate

2-3

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.

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.

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 2-3. Placing the CPU into the Socket

Figure 2-4. Inspecting the CPU Installation

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.

H8DMT/H8DMT-IBX/H8DMT-F/H8DMT-IBXF User’s Manual

2-4

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.

2-4 Installing Memory

Installing Memory

1. Insert each memory module vertically into its slot, paying attention to the notch

along the bottom of the module to prevent inserting the module incorrectly (see

Figure 2-6).

2. Install to slots CPU1/DIMM1B and CPU1/DIMM1A first, then to CPU1/DIMM2B and

CPU1/DIMM2A, etc. Always install in pairs and in the numerical order of the DIMM

slots. See "Support" information below.

3. Gently press down on the memory module until it snaps into place.

4. With two CPUs installed, repeat step 2 to populate the CPU2 DIMM slots.

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.

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

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.

Chapter 4

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.

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.

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.

System Time/System Date

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

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 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.
