Introduction

1-1 Overview

The SUPER P6DGS/P6DGE/P6DGU/P6SGU supports Pentium II 233-333 MHz
processors at a 66MHz bus speed and Pentium II/III 350-700 MHz proces­sors at a 100MHz bus speed. The SUPER P6DGU/P6DGS/P6DGE supports
single or dual Pentium II/III processors and the SUPER P6SGU supports a
single Pentium II/III processor. All four motherboards are based on Intel’s
440GX chipset, which enables 66/100 MHz system bus speed, Accelerated
Graphics Port (AGP), Wake-on-LANÔ , SDRAM, concurrent PCI and Ultra
DMA/33 for a 33 MB/s burst transfer rate.

While all of the motherboards are the ATX form factor, the P6DGU and
P6DGE have 5 PCI and 2 ISA slots with one slot shared. The SUPER P6DGS
and P6SGU have 4 PCI and 3 ISA slots with one slot shared. All four
motherboards have the AGP port, and can accommodate 2 GB unbuffered
SDRAM or registered SDRAM memory in 4 168-pin DIMM sockets. All also
support ECC or non-ECC memory.

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

Wake-on-LAN enables 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 PC 98-ready and support for Advanced Configuration
and Power Interface (ACPI).

Included I/O on all motherboards are 2 EIDE ports, a floppy port, an ECP/EPP
parallel port, a PS/2 mouse and PS/2 keyboard, 2 serial ports, an infrared port
and 2 USB ports. The SUPER P6DGU and P6SGU provide an onboard Adaptec
7890 Ultra2 SCSI controller with a data transfer rate of up to 80 MB/s, and
optional RAID III (ARO-1130U2). The SUPER P6DGS has an integrated
onboard Adaptec 7895 MultiChannel UW SCSI controller. The dual channels
allow a data transfer rate of 40 MB/s per channel. Additionally, this moth­erboard has an onboard RAIDport to support the Adaptec ARO-1130SA/CA
RAIDport II card for increased I/O performance and fault tolerance.

Chapter 1: Introduction

1-13

1-2 Chipset Overview

The 440GX chipset, developed by Intel, is the ultimate processor platform tar­geted for 3D graphics and multimedia applications. Along with System-to-PCI
bridge integrated with optimized DRAM controller and data path, the chipset
introduces the Accelerated Graphics Port (AGP) interface. AGP is a high per­formance, component level interconnect targeted at 3D applications and is 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 technology. 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 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER P6DGS,
P6DGE, P6DGU and P6SGU. All have an onboard System Hardware Monitor
chip that supports PC health monitoring.

Seven Onboard Voltage Monitors for the CPU Core(s),
CPU I/O, +3.3V,

±±

±12V

The onboard voltage monitor will scan the seven monitored voltages continuously.
Once a voltage becomes unstable, it will report a warning or an error message
onscreen. Users can adjust the threshold of the monitored voltage to determine
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 fan is controlled by the ACPI BIOS and the ACPI enabled
operating system. The thermal fans are controlled by the overheat detection
logic.

SUPER P6DGS/P6DGE/P6DGU/P6SGU Manual

1-14

Environmental Temperature Control

The thermal control sensor monitors the real-time CPU temperature. It will
turn on a back-up 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 if 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 will turn on when the power is on. It can be turned off when
the CPU is in sleep mode. When the CPU is in sleep mode it does not run at
full power, and therefore generates less heat. For power saving purposes,
the user has the option to shut down the CPU fan at such times.

CPU Overheat Alarm, LED and Control

This feature is available when the user enables the CPU overheat warning
function in the BIOS. The overheat alarm will activate when the CPU tem­perature exceeds a temperature defined by the user. When the overheat
alarm is activated both the overheat fan and the LED are triggered.

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 micro-switch 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.

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager
(optional). The user can be notified of certain system events. For example,
if the system is running low on virtual memory, the hard drive space is not
enough to save the data, you are then alerted of the potential problems.

Chapter 1: Introduction

1-15

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 switching voltage regulator for the CPU core can support up to 20A of
current, with auto-sensing voltage ID ranging from 1.8V to 3.5V. This will
allow the regulator to run cooler and makes the system more stable.

Intel LANDesk® Client Manager (LDCM) Support

As the computer industry evolves, PC systems 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 notification of system events

• Transfer files to and from client workstations

• Remotely reboot 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, 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.

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 Windows98.
In order to enable ACPI, the default APM mode must be disabled in BIOS
(see page 5-12). To install Windows 98 with ACPI, enter DOS and type
"setup /p j" at the CDROM prompt (usually D:\) with the Windows98 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 describing a PC that is
always on but appears to be off and that responds immediately to users
and 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 a USB keyboard is the only keyboard in the system, it will function like a
normal keyboard during system boot-up.

Chapter 1: Introduction

1-17

Real Time Clock Wake-Up Alarm

The PC may appear to be off when not in use, but it is still capable of
responding to preset wake-up events. The user can set a timer in the BIOS
to wake-up the system at a predetermined time.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a
system suspend button. When the user presses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Pressing 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 system circuitry alive. In case the
system malfunctions and you want to turn off the power, just depress the
power button for 4 seconds. The system will turn off and no power will be
provided to the motherboard.

External Modem Ring-On

An external modem ringing can be used to trigger a wake-up when the
system is in the SoftOff state .

Wake-On-LAN (WOL)

Wake-on-LAN is defined as the ability of a management application to re­motely power up a computer that has been 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) used to connect to the 3-pin
header on a Network Interface Card (NIC) that has WOL capability. Note
that Wake-on-Lan can only be used with an ATX 2.01 (or above) compliant
power supply.

1-6 Power Supply

As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for Pentium II/III
CPUs that have high clock rates.

SUPER P6DGS/P6DGE/P6DGU/P6SGU Manual

1-18

The SUPER P6DGS/P6DGE/P6DGU/P6SGU accommodates ATX power sup­plies. Although most power supplies generally meet the specifications required
by the CPU, some power supplies 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 separate noise from the computer. You can 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 Super I/O chip include a floppy disk
drive controller compatible with industry standard 82077/765, a data sepa­rator, write pre-compensation circuit, 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.

The Super I/O 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 rate up to 115.2 Kbps and also
advanced speed with baud rates of 230 K, 460 K, or 921 Kbps which
support higher speed modems.

The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capa­bilities Port (ECP). Also available, through the printer port interface pins, are:
Extension FDD Mode and Extension 2FDD Mode allowing 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 has auto power management to
reduce power consumption.

The Super I/O complies with Microsoft PC97 Hardware Design Guide. IRQs,
DMAs and I/O space resources are flexible to meet ISA PnP requirements.
Moreover, it meets the specifications of PC97's power management require­ments: ACPI and DPM (Device Power Management).

1-8 AIC-7895 MultiChannel

TM

Single-Chip Ultra SCSI

The SUPER P6DGS has an onboard SCSI controller that is 100% compatible
with all major operating and hardware platforms. PCI 2.1 and SCAM Level 1
compliance are assured. Two independent SCSI channels provide a per channel
data transfer rate of 40 MB/s. Connectors include two 68-pin, 16-bit Ultra Wide
SCSI connectors (JA1/JA2) and a 50-pin, 8-bit SCSI connector (JA3). You can
connect up to 15 devices (seven 8-bit internal and eight 16-bit internal or external
SCSI devices, or 15 Wide internal and external SCSI devices).

When Fast SCSI devices are connected, the total length of all cables (internal
and external) must not exceed 3 meters (9.8 ft) to ensure reliable operation. If
no Fast SCSI devices are connected, the total length of all cables must not
exceed 6 meters (19.7 ft).

The AIC-7895 consolidates the functions of two SCSI chips, eliminating the need
for a PCI bridge. Reducing PCI bus loading enables system capabilities to be
expanded with additional PCI devices.

The AIC-7895 functions with Adaptec RAIDport II (ARO-1130SA/1130CA) to de­liver RAID functionality.

1-9 AIC-7890 Ultra2 SCSI Controller

Note: If you are using a low voltage differential Hard Drive, it is recommended you use LVD/
SE Ultra2 SCSI cable. LVD/SE cable offers increased length, and can accommodate more
devices.

The SUPER P6DGU/P6SGU has an onboard SCSI controller that is 100% com­patible with all major operating and hardware platforms. The AIC-7890 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, fully supports the power management requirements
specified in Microsoft's PC 97 guidelines, and provides SCAM level 2 support.
The AIC-7890 functions with Adaptec RAIDport III (ARO-1130U2) 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. The AIC-7890
