Introduction

1-2 Chipset Overview

Intel’s 840 chipset is based on the new modular design introduced by the
800 series chipsets and consisting of three main components. The 82840
Memory Controller Hub (MCH) provides support for AGP2x/4x and AGP Pro.
An 82801 I/O Controller Hub (ICH) connects the PCI slots, IDE controllers
and USB ports to the MCH via an accelerated hub architecture. The third
main component is the 82802 Firmware Hub (FWH), which stores both sys­tem and video BIOS and includes a Random Number Generator (RNG).

Memory Controller Hub (MCH)

The MCH includes the host (CPU) interface, DRAM interface, ICH interface,
4xAGP interface and P64 interface for the 840 chipset. It contains ad­vanced power management logic and supports dual channels for DRAM.
The AGP 2.0 interface supports 4x data transfer and 2x/4x fast write capa­bility and operates at a peak bandwidth of 266 MB/sec. The MCH host
interface bus runs at 133/100 MHz.

I/O Controller Hub (ICH)

The ICH is the Controller Hub for the I/O subsystem and integrates many of
the Input/Output functions of the 840 chipset, including a two-channel
UDMA/66 Bus Master IDE controller. It also provides the interface to the PCI
Bus and communicates with the MCH over a dedicated hub interface.

Firmware Hub (FWH)

The FWH is a component that brings added security and manageability to
the PC platform infrastructure. This device includes an integrated Random
Number Generator (RNG) for stronger encryption, digital signing and secu­rity protocols. The FWH stores the system BIOS and video BIOS to eliminate
a redundant nonvolatile memory component.

PCI 64-bit Hub (P64H)

The P64H chip provides a bridge between the MCH and the PCI Bus. It has
a 16-bit primary hub interface to the MCH and a secondary 64-bit PCI Bus
interface, which supports both 64-bit and 32-bit PCI devices. The P64H is
PCI 2.2 compliant.

SUPER S2DM3/S2DME User's Manual

Introduction

Suspend to RAM (STR)

When the system goes into a sleep state, power is removed from most of
the system components but can remain supplied to RAM to quickly restore
the system to its previous state of operation. Because system restoral
happens in only ~5 seconds, applications that were open before the sleep
state can reopen for immediate access. In STR, all data in system memory
is stored in RAM when the system is suspended and system power is
turned off (the power supply fan also shuts off). You must be running
ACPI for this feature to take effect. See page 1-16 for details on initiating
ACPI. All drivers and add-on cards must be ACPI supported for STR to
function. Note: To support the STR function, your power supply must
provide a +5V standby voltage that supplies at least 720 mA of current.

Alert on LAN 2 (AOL2) (S2DM3 only)

AOL2 ASIC brings an advanced level of management interface between a
remote management console/server and the client system. It provides inter­faces to the 82559 Ethernet controller chip and to system monitoring de­vices. AOL2 can send "Alert" messages to the mangagement console to
notify administrators of important events or problems such as high tempera­tures, chassis intrusion and voltages exceeding safe margins.

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond
when AC power is lost and then restored to the system. You can choose
for the system to remain powered off (in which case you must hit the
power switch to turn it back on) or for it to automatically return to a power
on state. See the Power Lost Control setting in BIOS on page 4-11 of this
manual to change this setting. The default setting is Always OFF.

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
S2DM3/S2DME. All have an onboard System Hardware Monitor chip that
supports PC health monitoring.

Chapter 1: Introduction

1-15

Introduction

Five Onboard Voltage Monitors for the CPU Core(s), +3.3V,

++

++

+5V and

++

++

+12V

The onboard voltage monitor will scan these five 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 define
the sensitivity of the voltage monitor.

Four-Fan Status Monitor with Firmware/Software On/Off
Control

The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin CPU and chassis fans are controlled by the power manage­ment functions. The thermal fan is controlled by the overheat detection
logic.

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and
will turn on the thermal control fan whenever the CPU temperature exceeds
a user-defined threshold. The overheat circuitry runs independently from
the CPU. It can continue to monitor for overheat conditions even when the
CPU is in sleep mode. Once it detects that the CPU temperature is too high,
it will automatically turn on the thermal control fan to prevent any overheat
damage to the CPU. The onboard chassis thermal circuitry can monitor the
overall system temperature and alert users when the chassis temperature
is too high.

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It can be turned off
when the CPU is in sleep mode. When in sleep mode, the CPU will not run
at full power, thereby generating less heat.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning
function in the BIOS (see page 4-17). This allows the user to define an
overheat temperature. When this temperature is exceeded, both the over­heat fan and the warning LED are triggered.

Introduction

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager
(optional). It is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insuf­ficient hard drive space for saving the data, you can be alerted of the
potential problem.

Hardware BIOS Virus Protection

The system BIOS is protected by hardware so that no virus can infect the
BIOS area. The user can only change the BIOS content through the flash
utility provided by SUPERMICRO. This feature can prevent viruses from
infecting the BIOS area and destroying valuable data.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 1.3V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.

1-4 ACPI/PC 98 Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro­vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft­ware. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers. This also
includes consumer devices connected to the PC such as VCRs, TVs, tele­phones and stereos.

In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper­ating system-independent interface for configuration control. ACPI lever­ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win­dows 98 and Windows NT 5.0. Note: To utilize ACPI, you must reinstall
Windows 98. To reinstall Windows 98 with ACPI, enter DOS and type
"setup /p J" at the CDROM prompt (usually D:\) with the Windows 98 CD
loaded. (Make sure you include the spaces after "setup" and "p".) Then hit
<Enter>. You can check to see if ACPI has been properly installed by

looking for it in the Device Manager, which is located in the Control Panel in
Windows.

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 the USB keyboard is the only keyboard in the system, the USB keyboard
will work like a normal keyboard during system boot-up.

Real Time Clock Wake-Up Alarm

Although the PC may be perceived to be off when not in use, it is still
capable of responding to preset wake-up events. In the BIOS, the user can
set a timer to wake-up the system at a predetermined time (see page 4-14)

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.

Introduction

External Modem Ring-On

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.

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, up­dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboards have 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.

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 SUPER S2DM3/S2DME accommodates ATX power supplies. Although
most power supplies generally meet the specifications required by the CPU,
some are inadequate. You should use one that will supply at least 300W of
power - an even higher wattage power supply is recommended for high­load configurations. Also, to support the STR function, your power supply
must provide a +5V standby voltage that supplies at least 720 mA of cur­rent.

It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 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.

2-1 Static-Sensitive Devices

Static-sensitive electrical discharge can damage electronic components. To
prevent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient to protect your equipment from
static discharge.

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.

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.
