Chapter 1: 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.

Introduction

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.

Suspend to RAM (STR)

When the system goes into a sleep state, power is removed from most of

Introduction

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 1-22 for details on initiating
ACPI. All drivers and add-on cards must be ACPI supported for STR to
function.

Alert on LAN 2 (AOL2)

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
PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME. All have an onboard System Hardware Moni­tor chip that supports PC health monitoring.

The onboard voltage monitor will scan these seven 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.

Introduction

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.

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager

Introduction

(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
