1-2 Chipset Overview

The VIA Apollo Pro266 chipset is a high performance, cost-effective and
energy efficient chipset for the implementation of AGP/V-Link/PCI/LPC com­puter systems based on 64-bit, 370 Pentium III (66 MHz/100MHz/133MHz),
processors.

VIA's Apollo Pro266 chipset consists of two major components: the VT8633
V-Link Memory Host System Controller(-North-bridge) and the VT8233 V­Link Client PCI/LPC Controller (-South-bridge). The VT8633 Host System
Controller provides superior performance between the CPU, DIMM, AGP
bus, and V-Link inferface with pipelined, burst, and concurrent operation.
The VT8233 V-Link Client Controller is a highly integrated PCI/LPC controller.
Its internal bus structure is based on 66MHz PCI bus that provides 2x band­width. The VT8233 integrated Clint V-Link Controller, which supports 266
MB bandwidth between Host/Client V-Link interface, provides a V-Link PCI
and V-Link LPC controller. It supports five PCI slots arbitration and decod­ing for all integrated functions and LPC bus.

Memory support and AGP capability for the VT8633 chip

The VT8633 supports SDRAM memory up to 4 GB. The DRAM controller
supports SDRAM and VCSDRAM (Virtual Channel SDRAM) in a flexible mix/
match manner. The SDRAM interface allows zero wait state bursting be­tween the DRAM and the data buffers at 66/100/133 MHz.

The VT8633 Controller also supports full AGP v.2.0 capability for maximum
bus utilization including 2x and 4x mode transfer, SBA (Side Band Address­ing), Flush/Fence commands and pipelined grants. The VT8633 also pro-

vides flexible CPU/AGP/PCI remapping control which supports major AGP­based 3D and DVD multimedia accelerators.

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 the BIOS chapter of this
manual to change this setting. The default setting is Always OFF.

1-3 Special Features

Advanced Communications Riser Card (ACR)

The ACR (Advanced Communications Riser Card), combining several
existing communications buses with new and advanced
communications buses, provides low-cost, high-performance
communications solutions to the industry. The ACR Specification
supports modem, audio, Local Area Network (LAN), and Digital
Subscriber Line (DSL). Pins are also reserved for future wireless bus
support. The ACR Specification enables riser-based broadband
communications, networking peripheral and audio subsystem designs.

ACR accomplishes this in an open-standards context.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
370DDE motherboard.

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.

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 activate 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.

Chapter 1: Introduction

1-19

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. 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
(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.

1-5 ACPI/PC 99 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, Windows NT, and Windows 2000. 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, it keyboard will
function 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.

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 main 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 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
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Wake-On-LAN
must be enabled in BIOS. 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 processors that
have high CPU clock rates of 300 MHz and above.

The SUPER 370DDE 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 2.02 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.

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

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).

1-7 Super I/O

The functions of the disk drive adapter for 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 disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It

2-1Static-Sensitive Devices

ElectroStatic Discharge (ESD) can damage electronic components. To pre­vent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient to protect your equipment
from ESD.

Precautions

• Use a wrist strap designed to prevent electrostatic discharge that is
grounded to the computer chassis.

• Touch a grounded metal computer object before removing the board from
the antistatic bag.

• Handle the board by its edges only; do not touch its components, periph­eral chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when

not in use.

• For grounding purposes, make sure your computer chassis provides ex­cellent conductivity amongst the power supply, the case, the mounting
fasteners and the motherboard.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage.
When unpacking the board, make sure the person handling it is static pro­tected.

Installation

Heat Sink

Follow the instructions that came with your processors or heat sinks to
attach heat sinks to the processors. Each of your heat sinks should
have a 3-pin fan cable connecting to the CPU FAN header. Make sure
that good contact is made between the processors and the heat sinks.
Insufficient contact, incorrect types of heat sinks, fans, or thermal
compound used or improper amount of thermal compound applied on the
CPU die can cause the processors to overheat, which may crash the
system.

Processor

You are now ready to install the processors. Your 370DDE motherboard
has two 370-pin, FCPGA type sockets, which support 370-pin Pentium III
FCPGA (not SEPP) 500 MHz-1GHz processors. The 370SDA motherboard
supports only one Pentium III FCPGA 500 MHz-1GHz CPU -- or supports a
single Celeron PPGA/FCPGA 333-700 MHz processor. Lift the lever on the
FCPGA socket and install with the notched corner of the processor oriented
with pin 1. Fully seat the processor into the socket and then close the
lever. See Figure 2-1 for views of the FCPGA 370-pin socket before and
after processor installation -- the PPGA is similar.

2-2 Processor Installation

When handling the processor package, avoid placing
direct pressure on the label area of the fan.

The following pages cover the installation procedures. You should install
the processor in the motherboard first, then install the motherboard in the
chassis, then the memory and add-on cards, and finally the cables and
drivers. Following the installation procedures in the order they appear in
this chapter should eliminate the most common problems encountered when
building a system.

IMPORTANT: Always connect the power cord last, and always re­move it before adding, removing or changing any hardware compo­nents.
