Chapter 1: Introduction
1-2 Chipset Overview
The H8SMU motherboard 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 processor.
MCP55 Pro Media and Communications Processor
The MCP55 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, a single 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 effi cient use of memory in
multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.

H8SMU User’s Manual
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the H8SMU. The
motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for CPU core, 3.3V, +5Vin, +12Vin,
+5V standby and battery voltage
The onboard voltage monitor will scan these voltages continuously . 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 moni-
tor. 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 100A
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 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 (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 motherboard 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
H8SMU 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 H8SMU accommodates 12V ATX power supplies. Although most power supplies 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 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 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 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 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 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 fl exibly adjusted
to meet ISA PnP requirements, which support ACPI.

2-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic com ponents. T o prevent damage 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 manufac-
turer. 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 Procedures
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.

H8SMU User's Manual
!
2-2 Processor and Heatsink Installation
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.
CPU Backplates
A CPU backplate (BKT-0017L) has been included in the retail box. The backplate
prevents the CPU area of the motherboard from bending and provides a base for
attaching the retention module. To install, the backplate, begin by peeling off the
release paper to expose the adhesive. On the underside of the motherboard,
locate the two holes on either side of the CPU socket. Attach the adhesive side
of the backplate to the board by inserting the standoffs into the two holes and
applying light pressure so that the backplate sticks to the underside of the board.
See Figure 2-1.
Installing the Processor
1. Lift the lever on CPU socket until it
points straight up.
2. Use your thumb and your index fi n-
ger to hold the CPU. Locate pin 1 on
the CPU socket and pin 1 on the CPU.
Both are marked with a triangle.
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.
Triangles
2-2
4. With the CPU inserted into the
socket, inspect the four corners of the
CPU to make sure that it is properly
installed and fl ush with the socket.
5. Gently press the CPU socket lever
down until it locks in the plastic tab.
Chapter 2: Installation
Installing the Heatsink Retention Modules
A heatsink retention module (BKT-0018L) and two screws have been included in
the retail box. Once installed, it is used to help attach the heatsink to the CPU.
To install, position the module so that the CPU backplate standoffs insert through
the holes on the heatsink retention module and the four feet on the module contact
the motherboard. Secure the retention module to the backplate with two of the
screws provided. See Figure 2-1. Note: BKT-0018L is included for use with nonSupermicro heatsinks only. When installing Supermicro heatsinks, only BKT-0017L
(CPU backplate) is needed. BKT-0018L was designed to provide compatibility with
clip-and-cam type heatsinks from third parties.
Figure 2-1. CPU Heatsink Retention Module Installation
2-3
H8SMU User's Manual
Installing the Heatsink
The use of active type heatsinks (except for 1U systems) are recommended. Connect the heatsink fan to the appropriate fan header on the motherboard. To install
the heatsink, please follow the installation instructions included with your heatsink
package (not included).
2-3 Mounting the Motherboard into a Chassis
All motherboards 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 motherboard and the chassis match. Although a chassis may have both plastic
and metal mounting fasteners, metal ones are highly recommended because they
ground the motherboard to the chassis. Make sure that the metal standoffs click
in or are screwed in tightly.
1. Check the compatibility of the motherboard ports and the I/O shield
The H8SMU motherboard requires a chassis that can support extended ATX boards
of 7" x 13" in size. Make sure that the I/O ports on the motherboard align with their
respective holes in the I/O shield at the rear of the chassis.
2. Mounting the motherboard onto the mainboard tray in the chassis
Carefully mount the motherboard onto the mainboard tray by aligning the motherboard mounting holes with the raised metal standoffs in the tray. Insert screws into
all the mounting holes in the motherboard that line up with the standoffs. Then use a
screwdriver to secure the motherboard to the mainboard tray - tighten until just snug
(if too tight you might strip the threads). Metal screws provide an electrical contact
to the motherboard ground to provide a continuous ground for the system.
2-4
Chapter 2: Installation
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. 512 MB, 1 GB, and 2
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.
Support
The H8SMU supports single or dual-channel, DDR2-800/667/533 unbuffered ECC/
non-ECC SDRAM.
Both interleaved and non-interleaved memory are supported, so you may populate
any number of DIMM slots (see charts on following page).
Populating two 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 charts on following page.
Optimizing memory performance
For best results, populate slots in the following order: slot 1A then 1B then 2A
then 2B.
Maximum memory: 8 GB.

SATA Ports
There are no jumpers to confi gure the SATA ports, which
are designated SATA0 through
SATA3. See the table on the
right for pin defi nitions.
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 SA TA 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.

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.

ECC/non-ECC SDRAM. Memory can be installed in interleaved or non-interleaved
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 motherboard 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 motherboard?

3-3
H8SMU 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 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 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
motherboard.
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 H8SMU. 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 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.

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.
POST codes may be read on the debug LEDs located beside the LAN port on the
