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 PIIISED/PIIISEA motherboard. The SUPER PIIISED/PIIISEA
supports Pentium® III 450-600 MHz, Pentium II 233-450 MHz and SEPP
CeleronTM 266-466 MHz processors .

Pentium II/III processors with the Dual Independent Bus (DIB) architecture are
housed in a package called a Single Edge Contact Cartridge (S.E.C.C.) .
Celeron processors that are packaged in the SEPP (Single Edge Processor
Package) cartridge are also supported by the PIIISED/PIIISEA. These car­tridge packages and their associated "Slot 1" infrastructure will provide the
headroom for future high-performance processors.

Chapter 1: Introduction

1-13

Introduction

1-2 Chipset Overview

Intel's 810 chipset was developed to bring new features to value PC plat­forms. Integrated audio and graphics eliminate the cost of discrete compo­nents and free up space for additional peripheral cards. These onboard
features are based on the AC'97 2.1 compliant link for audio and telephony
CODECs and the onboard graphics controller chip. The main bridge of the
810 is the Graphics and Memory Controller Hub (GMCH), which enables a
66, 100 or 133 MHz front side bus speed. An I/O Hub Controller (ICH)
integrates PCI peripherals and I/O functions with a dedicated 33 MHz PCI
bus. This hub separates the I/O devices from the GMCH for improved
performance. The 810's accelerated hub interface provides a 266 MB/sec
bandwidth between the GMCH and ICH for smoother-streaming video and
audio.

Graphics Memory Controller Hub (GMCH)

The GMCH is the host bridge of the 810 chipset and provides the interconnect
between the SDRAM and the rest of the system logic. It includes a system
memory DRAM controller, which supports a 64-bit 100 MHz DRAM array, and
utilizes Direct AGP (integrated AGP) technology to create vivid 2D and 3D effects
and images. Direct AGP features D.V.M.T. (Dynamic Video Memory Tech­nology), which provides richer graphics by dynamically utilizing memory to
meet changing graphic demands efficiently.

I/O Controller Hub (ICH)

The ICH is the I/O Controller Hub for the I/O subsystem and integrates many
of the functions required by today's PC platforms. It provides the interface
to the PCI Bus and communicates with the GMCH over a dedicated hub
interface. There are two versions of the ICH: the ICH and the ICH0. The
PIIISED/PIIISEA has the ICH version, which supports Ultra DMA/66.

Audio Modem Riser (AMR)

The AMR is a new 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.

SUPER PIIISED/PIIISEA Manual

1-14

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) to enable stronger encryption, digital signing and
security protocols. The FWH stores 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
restoration 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.

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 4-20 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
PIIISED/PIIISEA. The motherboard has an onboard System Hardware Monitor
chip that supports PC health monitoring.

Chapter 1: Introduction

1-15

Introduction

Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V,

±±

±±

±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 user­defined 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.

SUPER PIIISED/PIIISEA Manual

1-16

Introduction

System Resource Alert

This feature is available when used with the Super Doctor utility program. It
is used to notify the user of certain system events, such as a user-defined
CPU temperature being exceeded, voltages sensed as being too high or
low, fan failure and chassis intrusion. (Utilizing chassis intrusion requires
a microswitch to be attached between the chassis and the JL1 header on
the motherboard.)

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 Windows

98. Note: 1. Windows NT 4.0 does not support ACPI. 2. To install 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

Chapter 1: Introduction

1-17

Introduction

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 motherboard has a 3-pin header (WOL) to connect to the 3-pin header
on a Network Interface Card (NIC) that has WOL capability. Note that Wake­On-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 of 300 MHz and above.

The SUPER PIIISED/PIIISEA accommodates ATX power supplies. Although
most power supplies generally meet the specifications required by the CPU,
some are inadequate.

It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.01 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.

Note: To support the keyboard wake-up function, your power supply must
be ATX 2.01 or higher and must provide a minimum standby voltage of 720
mA.

Introduction

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy 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 floppy disk
drives. The Super I/O supports four 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 IRQs, DMAs and I/O space resources of the Super I/O can flexibly
adjust to meet ISA PnP requirements, which suppport ACPI and APM (Ad­vanced Power Management).
