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 or 100 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.

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
370SWD and 370SWT have the ICH version, which supports ATA66. The
370SWM has the ICH0, which supports ATA33.

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.

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 FWW 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 be reopened 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 1-19 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
370SWD/370SWT/370SWM . All have an onboard System Hardware Moni­tor chip that supports PC health monitoring.

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
settings in BIOS (see page 4-18). These settings allow the user to enable
a warning and define the 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 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 too

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.)

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 SUPERMICRO's Super Doctor utility.

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
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
