Introduction

1-1 Overview

The SUPER S2DG2/S2DGU/S2DGE/S2DGR supports dual Pentium II Xeon
and dual Pentium III Xeon processors. All four motherboards are based on Intel’s
440GX chip set, which supports a 100 MHz system bus speed, an Accelerated
Graphics Port (AGP), Wake-on-LAN, SDRAM, concurrent PCI and a 33 MB/s
Ultra DMA burst data transfer rate.

While all of the motherboards are the ATX form factor, the S2DG2, S2DGU and
S2DGE have 5 PCI and 2 ISA slots (with one shared). The S2DGR has 4 PCI
and 2 ISA slots (with one shared). All have an AGP port and can accommodate
up to 2 GB unbuffered SDRAM or registered SDRAM memory in 4 168-pin DIMM
sockets.

AGP reduces contention between the CPU and I/O devices by broadening the
graphics bandwidth to memory. It delivers a maximum of 532 MB/s in the 2x
transfer mode, which is quadruple the PCI speed!

Wake-On-LAN allows for the remote network management and configuration of
the PC, even in off-hours when the PC is turned off. This reduces the complexity
of managing the network.

Other features that maximize customer satisfaction and simplicity in managing
the computer are its support for the PC 98-ready and and the Advanced Configu­ration and Power Interface (ACPI) standards. With PC Health Monitoring, you
can protect your system from problems before they even occur.

All motherboards include the following I/O: 2 EIDE ports, a floppy port, an ECP/
EPP supported parallel port, PS/2 mouse and PS/2 keyboard ports, 2 serial
ports, an infrared port and 2 USB ports. The S2DGR has an integrated onboard
Adaptec 7895 dual UW SCSI controller. The dual channels enable a data transfer
rate of 40 MB/s per channel and an optional RAID II port (ARO-1130CA/SA). The
S2DG2 has the onboard Adaptec 7896 controller for Ultra2 LVD (Low Voltage
Device) SCSI, which enables a data transfer rate of 80 MB/s per channel and an
optional RAID III port (ARO-1130C). In addition, this motherboard has an onboard
RAID port to support the Adaptec ARO-1130C RAIDport III card for increased I/
O performance and fault tolerance. The S2DGU provides an onboard Adaptec
7890 Ultra2 LVD SCSI controller, which enables data transfer rates of up to 80
MB/s, and an optional RAID III port (ARO-1130C).

1-2 Chipset Overview

The 440GX chipset, developed by Intel, is the ultimate processor platform tar­geted for 3D graphics and multimedia applications. Along with a System-to-PCI
bridge integrated with an optimized DRAM controller and data path, this chipset
supports the Accelerated Graphics Port (AGP) interface. AGP is a high perfor­mance, component level interconnect targeted at 3D applications and based on
a set of performance enhancements to PCI. The I/O subsystem portion of the
440GX platform is based on the PIIX4, a highly integrated version of Intel's PCI­to-ISA bridge family.

The PCI/AGP and system bus interface controller (82443GX) supports up to two
Pentium II/III processors. It provides an optimized 72-bit DRAM interface (64-bit
data plus ECC). This interface supports 3.3V DRAM technologies. The control­ler provides the interface to a PCI bus operating at 33 MHz. This interface
implementation is compliant with the PCI Rev 2.1 Specification. The AGP inter­face is based on AGP Specification Rev 1.0. It can support data transfer rates
of up to 133 MHz (532 MB/s) .

1-3 Slot 2 Architecture

The Slot 2 architecture supports Intel Pentium II and III Xeon CPUs. This tech­nology offers a larger L2 cache that can run at full CPU speed.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER S2DG2/
S2DGU/S2DGE/S2DGR. All have an onboard System Hardware Monitor chip
that supports PC health monitoring.

Seven Onboard Voltage Monitors for the CPU Core(s), CPU I/

The onboard voltage monitor will scan these seven monitored voltages continu­ously. Once a voltage becomes unstable, a warning is given or an error message
is sent to the screen. Users can adjust the voltage thresholds to define the
sensitivity of the voltage monitor.

SUPER S2DG2/S2DGU/S2DGE/S2DGR Manual

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

The PC health monitor can check the RPM status of the cooling fans. The
thermal fans are controlled by the overheat detection logic.

Please Note: The

tachometer readings are for JT1, JT2 and JT3 only

.

Environmental Temperature Control

A thermal control sensor monitors the CPU temperature in real-time and will turn
on a back-up 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
back-up 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 is activated 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. For power saving purposes, the user has
the option to shut down the CPU fan.

System Overheat Alarm, LED and Control

This feature is available when the user enables the system overheat warning
function in BIOS (see page 5-18). The overheat alarm will activate when the
system temperature exceeds the temperature threshold configured by the user.
When the overheat alarm is activated, both the overheat fan and the warning LED
are triggered.

Note: The alarm, fan and LED will remain on until the com-

puter is restarted.

Chassis Intrusion Detection

The chassis intrusion circuitry can detect unauthorized intrusion to the system.
The chassis intrusion connector is located on JL1. Attach a microswitch to JL1.
When the microswitch is closed, it means that the chassis has been opened.
The circuitry will then alert the user with a warning message when the system
is turned on. This feature is available when the user is running Intel's LANDesk
Client Manager and SUPERMICRO's Super Doctor.

Chapter 1: Introduction

1-15

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager. 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 contents 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, with the auto-sensing voltage ID ranging from 1.3 to 3.5 volts. This will
allow the regulator to run cooler and thus make the system more stable.

Intel LANDesk® Client Manager (LDCM) Support

As the computer industry grows, PC systems have become more complex and
harder to manage. Historically, only experts have been able to fully understand
and control these complex systems. Today's users want manageable systems
that they can interact with automatically. Client Manager enables both admin­istrators and clients to:

• Review system inventory

• View DMI-compliant component information

• Back-up and restore system configuration files

• Troubleshoot

• Receive notifications for system events

• Transfer files to and from client workstations

• Remotely boot up client workstations

1-5 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 hardware, the 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.

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 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, it will work like a normal
keyboard during system boot-up.

Real-Time Clock Wake-up Alarm

The PC may be perceived to be off when not in use, but 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 5-14).

Chapter 1: Introduction

1-17

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 wake­up. During the SoftOff state, the ATX power supply provides power to keep the
required circuitry on 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.

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing
when the system is in SoftOff state. Note that the 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. Note that Wake-On­LAN can only be used with an ATX 2.01 (or above) compliant power supply.

1-6 Power Supply Requirements

As with all computer products, a stable power source is necessary for proper and
reliable operation. This is even more important for the 400 MHz and higher clock
rates of Xeon processors.

The SUPER S2DG2/S2DGU/S2DGE/S2DGR accommodates ATX power sup­plies. Although most power supplies generally meet the specifications required
by the CPU, some are inadequate.

It is highly recommended that you use a high quality power supply that meets
ATX power supply Specification 2.01. Additionally, in areas where noisy power
transmission is present, you may choose to install a line filter to shield the

SUPER S2DG2/S2DGU/S2DGE/S2DGR Manual

1-18

computer from noise. It is recommended that you also install a power surge
protector to help avoid problems caused by power surges.

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk drive
controller 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 into 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 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 rates of up to 115.2 Kbps as well as an advanced speed with baud rates
of 230 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). Extension FDD and Extension 2FDD Modes are also available through
the printer port interface pins to allow one or two external floppy disk drives to
be connected.

The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage­ment through SMI or SCI function pins. It also features auto power management
to reduce power consumption.

The Super I/O complies with the Microsoft PC98 Hardware Design Guide.
IRQs, DMAs and I/O space resources can flexibly adjust to meet ISA PnP
requirements. Moreover, it meets the specification of PC98's power management
requirement: ACPI and APM (Advanced Power Management).

1-8 AIC-7890 Ultra2 SCSI Controller (S2DGU)

Note: If you are using a low voltage differential hard drive, it is recommended that you use an
LVD/SE Ultra2 SCSI cable. LVD/SE cables offer increased length and can accommodate up to
15 devices.

The SUPER S2DGU has an onboard Adaptec SCSI controller that is 100%
compatible with all major operating and hardware platforms. The Adaptec AIC­7890 controller provides advanced PCI-to-SCSI Ultra2 SCSI host adapter features
in a 272-pin Ball Grid Array (BGA) package, as well as containing an integrated
dual mode (LVD/SE) transceiver. The AIC-7890 Ultra2 SCSI chip connects to a
32-bit PCI bus. It is PCI 2.1 compliant and fully supports the power management
requirements specified in the Microsoft PC98 guidelines. The AIC-7890 functions
with Adaptec RAIDport III (ARO-1130C) to deliver RAID functionality.

The AIC-7890 Ultra2 SCSI controller, used together with the AIC-3860 trans­ceiver, allows Ultra2 and single-ended devices to operate together on the same
SCSI bus without inpacting Ultra2 performance and cable lengths. Connectors
on the S2DGU include one 68-pin 16-bit Ultra2 SCSI connector (JA1), one 68-pin
16-bit Ultra Wide SCSI connector (JA2) and one 50-pin 8-bit SCSI connector
(JA4). The controller allows you to connect a total of 15 SCSI devices, with a
maximum of 7 devices on the 50-pin SCSI connector.

1-9 AIC-7895 Dual Channel Ultra Wide SCSI Controller

(S2DGR)

The SUPER S2DGR has an onboard Adaptec SCSI controller that is 100%
compatible with all major operating and hardware platforms. PCI 2.1 compliance
is assured. Two independent Ultra Wide SCSI channels provide a data transfer
rate of 40 Mbytes/sec per channel. Connectors on the S2DGR include two 68­pin 16-bit Ultra Wide SCSI connectors (JA1/JA2) and one 50-pin 8-bit SCSI
connector (JA3). The controller allows you to connect a total of 30 SCSI devices
(15 for each channel), with a maximum of 7 devices on the 50-pin SCSI connec­tor.

The AIC-7895 consolidates the functions of two SCSI chips, eliminating the need
of a PCI bridge. Reducing PCI bus loading allows you to expand your system
capabilities with additional PCI devices.

The AIC-7895 functions with Adaptec RAIDport II (ARO-1130SA/1130CA) to de­liver RAID functionality. For information on installing onboard SCSI under Win­dows NT, refer to page 3-6 in the FAQ section of this manual.
