Preface

About This Manual

This manual is written for system integrators, PC technicians and
knowledgeable PC users. It provides information for the installation and use
of the SUPER PIIISCA/PIIISCD/PIIISCE/370SCD motherboard. The SUPER
PIIISCA/PIIISCD/PIIISCE supports Pentium® III 450-733 MHz processors and
Pentium II 350-450 MHz processors. The 370SCD supports Pentium III
FCPGA 500-700 MHz processors.

Pentium II processors with the Dual Independent Bus (DIB) architecture are
housed in a package called a Single Edge Contact Cartridge (SECC).
Pentium III processors are packaged in SECC2 type cartridges. FCPGA
processors are housed in a 370-pin package.

Manual Organization

Chapter 1 includes a checklist of what should be included in your mainboard

box, describes the features, specifications and performance of the SUPER
PIIISCA/PIIISCD/PIIISCE/370SCD mainboard and provides detailed informa­tion about the chipset.

Chapter 2 begins with instructions on handling static-sensitive devices. Read
this chapter when you want to install the processor and RIMM/DIMM memory
modules and when mounting the mainboard in the chassis. Also refer to this
chapter to connect the floppy and hard disk drives, the IDE interfaces, the
parallel and serial ports and the twisted wires for the power supply, the reset
button, the keylock/power LED, the speaker and the keyboard.

If you encounter any problems, see Chapter 3, which describes troubleshoot-
ing procedures for the video, the memory and the setup configuration stored
in CMOS. For quick reference, a general FAQ [Frequently Asked Questions]
section is provided. Instructions are also included for contacting technical
support. In addition, you can visit our web site at www.supermicro.com/
techsupport.htm for more detailed information.

Chapter 4 includes an introduction to BIOS and provides detailed information
on running the CMOS Setup utility.

1-2 Chipset Overview

Intel's 820 chipset brings advanced technology to the performance PC plat­form. A 133 MHz front side bus speed, 4xAGP, RDRAM and increased I/O
performance are some of the new capabilities offered by the 820. The main
bridge of the 820 is the Memory Controller Hub (MCH), which enables a 133
or 100 MHz front side bus speed. An I/O Controller Hub (ICH) integrates PCI
peripherals and I/O functions with a dedicated 33 MHz PCI bus. An accel­erated hub interface provides a 266 MB/sec bandwidth between the MCH
and ICH and also separates the I/O devices from the MCH for improved
performance.

Memory Controller Hub (MCH)

The MCH consists of the host (CPU) interface, DRAM interface, I/O interface
and AGP interface for the 820 chipset. It supports ECC memory for RDRAM.
The AGP 2.0 interface supports 4x data transfer and 4x fast write capabil­ity. The MCH host interface bus runs at 133/100 MHz.

I/O Controller Hub (ICH)

The ICH is the I/O Controller Hub for the I/O subsystem, which integrates
many of the functions required by today's PC platforms. It provides the
interface to the PCI Bus and communicates with the MCH over a dedicated
hub interface.

Memory Translator Hub (MTH)

The Memory Translator Hub allows the PIIISCA/PIIISCD/370SCD to support
DIMM (SDRAM) type memory. Note for the PIIISCA: Only one type of
memory can be used; if RIMM(s) are installed, then any installed DIMM(s)
will be disabled. The MTH does not support ECC, meaning that the use of
ECC memory will result in non-ECC operation.

Introduction

Audio Modem Riser (AMR)

The AMR is a modular specification that integrates the audio/modem func­tions on the motherboard by assigning the analog I/O functions to a riser
card. Integration of the audio/modem function enhances system capabilities
while reducing costs. The AMR interface is based on an AC-link that is

compliant with Intel’s Audio Codec ’97 version 2.1 specification.

Firmware Hub (FWH)

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

Suspend to RAM (STR)

When the system goes into a deep sleep (S3) state, power is removed from
most of the system components but remains 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.

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 Loss Control setting in BIOS on page 4-19 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
PIIISCA/PIIISCD/PIIISCE/370SCD. All three have an onboard System Hard

ware Monitor chip that supports PC health monitoring.

Seven Onboard Voltage Monitors for the CPU Core, Chipset

±5V and

±12V

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.

Three-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 4-18). This allows the user to define an
overheat temperature. When this temperature is exceeded, both the over­heat fan and the warning LED are triggered.
