SUPER 370SBA/370SBM/370SLA/370SLM User’s Manual
Notes

Chapter 1
Introduction
1-1 Overview
The SUPER 370SBA/370SBM/370SLA/370SLM motherboards support single
Intel® Celeron™ 333/366 MHz or higher Plastic Pin Grid Array (PPGA) processors at a 66 MHz front side bus speed. (The 100 MHz FSB speed is only
available when using 100 MHz FSB Celeron processors. ) The SUPER 370SBA
and 370SBM motherboards are based on Intel’s 440BX chip set, and the SUPER
370SLA and 370SLM motherboards are based on Intel’s 440LX chip set. Both
440BX and 440LX chip sets enable an Accelerated Graphics Port (AGP), Wakeon-LAN™, synchronous DRAM (SDRAM), concurrent PCI and dual IDE channels
that support Ultra DMA 33 MB/s burst data transfer rate.
The SUPER 370SBA and 370SLA are ATX form factor motherboards and have 4
PCI and 3 ISA slots. The SUPER 370SBM and 370SLM are microATX form factor
motherboards and have 3 PCI and 1 ISA slots. All four motherboards have an
AGP port, and can accommodate a total of 384 MB PC100 unbuffered SDRAM
memory with three 168-pin dual inline memory module (DIMM) sockets. The
SUPER 370SBA and 370SBM motherboards can support the 100 MHz front side
bus speed for future Celeron PPGA upgrades, and its 440BX chip set allows you
to install up to 768 MB of PC100 registered SDRAM. The SUPER 370SLA and
370SLM motherboards support the 66 MHz system bus speed only,
and can accept either PC66 EDO or PC100 SDRAM DIMMs.
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 (WOL) allows for 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 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 IDE 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.

1-3 Chip Set Overview
440BX Chip Set
The 440BX chip set, 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 chip set
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
440BX platform is based on the PIIX4E, a highly integrated version of Intel's PCIto-ISA bridge family.
The PCI/AGP and system bus interface controller (82443BX) supports one
Celeron processor. It provides an optimized 72-bit DRAM interface (64 bits of
data plus ECC) that supports 3.3V DRAM technology. The controller provides

1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER 370SBA,
370SBM, 370SLA and 370SLM. 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,
±±
±±
±5V,
and
±±
±±
±12V
The onboard voltage monitor scans these seven monitored 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.
Note: -5V is not required when using a microATX (SFX) power supply.
Three-Fan Status Monitors 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.
Environmental Temperature Control
The 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 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 does not run at full
power, and thereby generates less heat. For power saving purposes, the user
has the option to shut down the CPU fan.

CPU Overheat LED and Thermal Fan Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS (see page 5-17). The overheat sensor is triggered when the CPU
temperature exceeds the temperature configured by the user. When the overheat
sensor is triggered, both the overheat fan and the warning LED are activated.
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.
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 content through the flash utility
provided by SUPERMICRO. This feature can prevent viruses from infecting the
BIOS area and destroying valuable data.
Switching Voltage Regulator for the CPU Core
The switching voltage regulator for the CPU core can support up to 20A of current,
with the auto-sensing voltage ID ranging from 1.8V to 3.5V. 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 of system events
• Transfer files to and from client workstations
• Remotely boot up client workstations
1-6 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 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 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, 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 5-14).
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 wakeup. 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.
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 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 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-OnLan can only be used with an ATX 2.01 (or above) compliant power supply.
