Chapter 1: Introduction

1-2 Chipset Overview

The H8DMU+ serverboard is based on the nVidia MCP55 Pro chipset. The nVidia

MCP55 Pro functions as Media and Communications Processor (MCP). Controllers

for the system memory are integrated directly into the AMD Opteron processors.

MCP55 Pro Media and Communications Processor

The MCP55 Pro is a single-chip, high-performance HyperTransport peripheral con-

troller. It includes a 28-lane PCI Express interface, an AMD Opteron 16-bit Hyper

Transport interface link, a six-port Serial ATA interface, a dual-port Gb Ethernet

interface, a single ATA133 bus master interface and a USB 2.0 interface. This hub

connects directly to CPU#1 and through that to CPU#2.

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.

1-9

H8DMU+ User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the H8DMU+. The

serverboard has an onboard System Hardware Monitor chip that supports PC

health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will scan these voltages continuously: CPU cores,

Hyper Transport (1.2V), memory banks (1.8V), 1.5V, MCP55 Core, 3.3V, 12V, -

12V, 5V, VSB and battery voltage. 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 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 deﬁ ne an overheat temperature. When

this temperature is exceeded or when a fan failure occurs, then, the Overheat/Fan

Fail warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The 5-phase-switching voltage regulator for the CPU core can support up to 120A

and auto-sense voltage IDs. This will allow the regulator to run cooler and thus

make the system more stable.

1-10

Chapter 1: Introduction

1-4 Power Conﬁ guration Settings

This section describes the features of your serverboard 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. Dur-

ing 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 serverboard.

Wake-On-LAN (JWOL)

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 serverboard has a 3-pin header

(JWOL) 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.

1-11

H8DMU+ User’s Manual

Wake-On-Ring Header (JWOR)

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the SoftOff state. Note that external modem ring-on can only

be used with an ATX 2.01 (or above) compliant power supply.

1-5 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 H8DMU+ accommodates 12V ATX power supplies. Although most power sup-

plies generally meet the speciﬁ cations required by the CPU, some are inadequate.

Important: a 3A or greater current supply on the 5V Standby rail is required.

It is strongly recommended that you use a high quality power supply that meets

12V ATX power supply Speciﬁ cation 1.1 or above. Additionally, 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.

Chapter 1: Introduction

1-6 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 genera-

tor, 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 supports two 360

K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,

500 Kb/s or 1 Mb/s.

It also 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 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.

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 serverboard 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 serverboard.

• Use only the correct type of CMOS onboard battery as speciﬁ ed by the manufac-

turer. Do not install the CMOS onboard battery upside down, which may result

in a possible explosion.

Unpacking

The serverboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

H8DMU+ User's Manual

2-2 Processor and Heatsink Installation

Exercise extreme caution when handling and installing the proces-

CPU Backplates

Two CPU backplates (BKT-0011L) have been preinstalled to the serverboard to

prevent the CPU area of the serverboard from bending and to provide a base for

attaching the heatsink retention modules.

sor. Always connect the power cord last and always remove it be-

fore adding, removing or changing any hardware components.

Installing the Processor (install to the CPU#1 socket ﬁ rst)

1. Begin by removing the cover plate

that protects the CPU. Lift the lever

3. Align pin 1 of the CPU with pin 1

of the socket. 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 in-

stalled and ﬂ ush 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 reten-

tion tab. For a dual-processor system,

repeat these steps to install another

CPU into the CPU#2 socket.

Note: if using a single processor, only

the CPU1 DIMM slots are addressable

for a maximum of 32 GB memory.

H8DMU+ User's Manual

Installing the Heatsink Retention Modules

Two heatsink retention modules (BKT-0012L) and four screws are included in the

retail box. Once installed, these are used to help attach the heatsinks to the CPUs.

To install, align the module with the standoffs of the preinstalled CPU backplate and

with the four feet on the module contacting the serverboard. Secure the retention

module to the backplate with two of the screws provided. See Figure 2-1. Repeat

for the second CPU socket.

Note: BKT-0012L is included for use with non-Supermicro heatsinks only. When

installing Supermicro heatsinks, only BKT-0011L (the pre-installed CPU backplate)

is needed. The BKT-0012L retention module was designed to provide compatibility

with clip-and-cam type heatsinks from third parties.

Figure 2-1. CPU Heatsink Retention Module Installation

Installing the Heatsink

The use of active type heatsinks (except for 1U systems) are recommended. Con-

nect the heatsink fans to the appropriate fan headers on the serverboard. To install

the heatsinks, please follow the installation instructions included with your heatsink

package (not included).

Chapter 2: Installation

2-3 Mounting the Serverboard into a Chassis

All serverboards and motherboards have standard mounting holes to ﬁ t 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.

1. Check the compatibility of the serverboard ports and the I/O shield

The H8DMU+ serverboard requires a chassis that can support extended ATX boards

of 12" x 13.05" in size. 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.

2. Mounting the serverboard onto the mainboard tray in the chassis

Carefully mount the serverboard onto the mainboard tray by aligning the serverboard

mounting holes with the raised metal standoffs in the tray. Insert screws into all

the mounting holes in the serverboard that line up with the standoffs. 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

CAUTION

Exercise extreme care when installing or removing memory modules

to prevent any possible damage.

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 2-2). See support information below.

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

Note: each processor has its own built-in memory controller, so the CPU2 DIMMs

cannot be addressed if only a single CPU is installed. 256 MB, 512 MB, 1 GB, 2

GB and 4 GB memory modules are supported. It is highly recommended that you

remove the power cord from the system before installing or changing any memory

modules.

2-5

H8DMU+ User's Manual

Support

The H8DMU+ supports single or dual-channel, DDR2-667/533/400 registered ECC

SDRAM.

Both interleaved and non-interleaved memory are supported, so you may populate

any number of DIMM slots (see note on previous page and chart on following

page). The CPU2 DIMM slots can only be accessed when two CPUs are installed

(however, the CPU2 DIMM slots are not required to be populated when two CPUs

are installed).

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. See chart on following page.

Optimizing memory performance

If two processors are installed, it is better to stagger pairs of DIMMs across both

sets of CPU DIMM slots, e.g. ﬁ rst populate CPU1 slots 1A and 1B, then CPU2 slots

1A, and 1B, then the next two CPU1 slots, etc. This balances the load over both

CPUs to optimize performance.

Maximum memory: 64 GB of DDR2-667/533/400 SDRAM - if only one CPU is

installed, maximum supported memory is halved (32 GB).

Figure 2-2. Side and Top Views of DDR2 Installation

To Install:

Insert module vertically and press down until it snaps into place. The release tabs should close - if they do not you should close them yourself.

Note: Notch

should align

To clear CMOS,

1) First power down the system and unplug the power cord(s).

2) With the power disconnected, short the CMOS pads with a metal object such as

a small screwdriver for at least four seconds.

3) Remove the screwdriver (or shorting device).

4) Reconnect the power cord(s) and power on the system.

2-10 Enabling SATA 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. 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.

Installing the OS/SATA Driver

Before installing the OS (operating system) and SATA RAID driver, you must decide

if you wish to have the operating system installed as part of a bootable RAID array

or installed to a separate non-RAID hard drive. If on a separate drive, you may

install the driver either during or after the OS installation. If you wish to have the

OS on a SATA RAID array, you must follow the procedure below and install the

driver during the OS installation.

Building a Driver Diskette

You must ﬁ rst build a driver diskette from the CD-ROM that was included with the

system. (You will have to create this disk on a computer that is already running and

with the OS installed.) Insert the CD into your CD-ROM drive and start the system.

A display as shown in Figure 2-7 will appear. Click on the icon labeled "Build Driver

Diskettes and Manuals" and follow the instructions to create a ﬂ oppy disk with the

driver on it. Once it's been created, remove the ﬂ oppy and insert the installation

CD for the Windows Operating System you wish to install into the CD-ROM drive

of the new system you are about to conﬁ gure.

Enabling SATA RAID in the BIOS

Before installing the Windows Operating System, you must change some settings

in BIOS. Boot up the system and hit the <Del> key to enter the BIOS Setup Utlility.

After the Setup Utility loads,

1. Use the arrow keys to move to the Exit menu. Scroll down with the arrow keys

to the "Load Optimal Defaults setting and press <Enter>. Select "OK" to conﬁ rm,

then <Enter> to load the default settings.

2-22

Chapter 2: Installation

2. Use the arrow keys to move to Advanced > Floppy/IDE/SATA Conﬁ guration >

nVidia RAID Setup and press the <Enter> key. Once in the submenu, enable the

"nVidia RAID Function" setting.

3. Hit the <F10> key to "Save Changes and Exit", then hit <Enter> to verify.

4. After exiting the BIOS Setup Utility, the system will reboot. When prompted

during the startup, press the <F10> key when prompted to run the nVidia RAID

Utility program.

Using the nVidia RAID Utility

The nVidia RAID Utility program is where you can deﬁ ne the drives you want to

include in the RAID array and the mode and type of RAID. Two main windows are

shown in the utility (see Figure 2-5). The "Free Disks" window on the left will list all

available drives. Use the arrow keys to select and move drives to the window on

the right, which lists all drives that are to become part of the RAID array.

Once you have ﬁ nished selecting the drives and type of RAID you wish to use for

your RAID array, press the <F7> key. You will be prompted to verify your choice; if

you want to continue with your choices, select "Yes". Note that selecting "Yes" will

clear all previous data from the drives you selected to be a part of the array. You

are then given the choice of making the RAID array bootable by pressing the the

<B> key. After you have ﬁ nshed, press the <Ctrl> and <X> keys simultaneously.

Figure 2-6 shows a list of arrays that have been set up with the utility.

Installing the OS and Drivers

With the Windows OS installation CD in the CD-ROM drive, restart the system.

When you see the prompt, hit the <F6> key to enter Windows setup. Eventually a

blue screen will appear with a message that begins "Windows could not determine

the type of one or more storage devices . . ." When you see the screen, hit the <S>

key to "Specify Additional Device", then insert the driver diskette you just created

into the ﬂ oppy drive. Highlight "Manufuacturer Supplied Hardware Support Disk"

and hit the <Enter> key. Highlight the ﬁ rst "nVidia RAID" driver shown and press

the <Enter> key to install it. Soon a similar blue screen will appear again. Again hit

the <S> key, then highlight the second item, "nForce Storage Controller" and press

the <Enter> key, then <Enter> again to continue with the Windows setup.

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all

of the procedures below and still need assistance, refer to the ‘Technical Support

Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.

Always disconnect the AC power cord before adding, changing or installing any

hardware components.

Before Power On

1. Check that the onboard power LED is lit (DP4 on the serverboard).

2. Make sure that the main ATX power connector at JPW1, the 8-pin connector at

JPW2 and the 4-pin connecor at J32 are all connected to your power supply.

3. Make sure that no short circuits exist between the serverboard and chassis.

4. Disconnect all ribbon/wire cables from the serverboard, including those for the

keyboard and mouse.

5. Remove all add-on cards.

6. Install a CPU and heatsink (making sure it is fully seated) and connect the in-

ternal (chassis) speaker and the power LED to the serverboard. Check all jumper

settings as well.

7. Use the correct type of onboard CMOS battery as recommended by the manufac-

turer. To avoid possible explosion, do not install the CMOS battery upside down.

8. Note that the 5VSB supplied from your power supply must provide >3 amps.

No Power

1. Make sure that no short circuits exist between the serverboard and the chas-

sis.

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Turn the power switch on and off to test the system.

5. The battery on your serverboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

No Video

1. If the power is on but you have no video, remove all add-on cards and cables.

2. Use the speaker to determine if any beep codes exist. Refer to Appendix A for

details on beep codes.

3-1

H8DMU+ User's Manual

NOTE

If you are a system integrator, VAR or OEM, a POST diagnostics

card is recommended. For I/O port 80h codes, refer to App. B.

Memory Errors

1. Make sure that the DIMM modules are properly and fully installed.

2. You should be using registered ECC DDR-2 memory (see next page). Also, it

is recommended that you use the same memory type and speed for all DIMMs in

the system. See Section 2-4 for memory details and limitations.

3. Check for bad DIMM modules or slots by swapping modules between slots and

noting the results.

4. Check the power supply voltage 115V/230V switch.

Losing the System’s Setup Conﬁ guration

1. Make sure that you are using a high quality power supply. A poor quality power

supply may cause the system to lose the CMOS setup information. Refer to Sec-

tion 1-6 for details on recommended power supplies.

2. The battery on your serverboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

3. If the above steps do not ﬁ x the setup conﬁ guration problem, contact your vendor

for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note

that as a serverboard manufacturer, we do not sell directly to end-users, so it is

best to ﬁ rst check with your distributor or reseller for troubleshooting services. They

should know of any possible problem(s) with the speciﬁ c system conﬁ guration that

was sold to you.

1. Please review the ‘Troubleshooting Procedures’ and 'Frequently Asked Questions'

(FAQs) sections in this chapter or see the FAQs on our web site before contacting

Technical Support.

2. BIOS upgrades can be downloaded from our web site.

Note: Not all BIOS can be ﬂ ashed depending on the modiﬁ cations to the boot block

code.

Chapter 3: Troubleshooting

3. If you still cannot resolve the problem, include the following information when

contacting us for technical support:

 Serverboard model and PCB revision number

 BIOS release date/version (this can be seen on the initial display when your

system ﬁ rst boots up)

 System conﬁ guration

An example of a Technical Support form is posted on our web site.

4. Distributors: For immediate assistance, please have your account number ready

when contacting our technical support department by e-mail.

3-3 Frequently Asked Questions

Question: What type of memory does my serverboard support?

Answer: The H8DMU+ supports up to 64 GB of DDR2-667/533/400 registered

ECC SDRAM with two CPUs installed. With only one CPU installed the maximum

memory support is halved. Memory can be installed in interleaved or non-inter-

leaved conﬁ gurations. See Section 2-4 for details on installing memory.

Question: How do I update my BIOS?

Answer: It is recommended that you not upgrade your BIOS if you are not experi-

encing problems with your system. Updated BIOS ﬁ les are located on our web site

(http://www.supermicro.com/aplus/support/bios). 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 serverboard model on the web page and download the corresponding

BIOS ﬁ le to your computer. Unzip the BIOS update ﬁ le, in which you will ﬁ nd the

readme.txt (ﬂ ash instructions), the afudos.exe (BIOS ﬂ ash utility) and the BIOS

image (xxx.rom) ﬁ les. Copy these ﬁ les to a bootable ﬂ oppy disk, insert the disk

into drive A and reboot the system. At the DOS prompt after rebooting, enter the

command "ﬂ ash" (without quotation marks) then type in the BIOS ﬁ le that you want

to update with (xxxx.rom).

Question: What's on the CD that came with my serverboard?

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.

3-3

H8DMU+ User's Manual

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 But-

ton Mode setting. When the On/Off feature is enabled, the serverboard 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 ﬁ rst 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.

Question: How do I connect the ATA133 cable to my IDE device(s)?

Answer: The 80-wire/40-pin high-density ATA133 IDE cable that came with your

system has two connectors to support two drives. This special cable must be used

to take advantage of the speed the ATA133 technology offers. Connect the blue

connector to the onboard IDE header and the other connector(s) to your hard

drive(s). Consult the documentation that came with your disk drive for details on

actual jumper locations and settings.

4-1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the H8DMU+. The AMI

ROM BIOS is stored in a ﬂ ash chip and can be easily upgraded using a ﬂ oppy

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 reﬂ ected

in this manual.

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 conﬁ gured. “Grayed-out” options cannot be conﬁ gured. The right frame

displays the key legend. Above the key legend is an area reserved for a text mes-

sage. 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.) Set-

tings 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.
