Preface

About this Manual

This manual is written for system integrators, PC technicians and knowledgeable PC
users. It provides information for the installation and use of the H8DMT/H8DMT-IBX/
H8DMT-F/H8DMT-IBXF serverboards. All these serverboards are based on the nVidia
MCP55 Pro chipset and support AMD Opteron™ processors with up to 64 GB of
DDR2-800/667/533/400 registered ECC SDRAM.

The differences between these serverboards is that some have full IPMI capability,
some have InfiniBand components and some have both or neither capability. Refer to
the chart below for details on which boards have which capabilities.

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. W ake-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).
