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.

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.
