Introduction
1-1Overview
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.

Chapter 1: Introduction
1-3Chip 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
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).
440LX Chip Set
The 440LX chip set, developed by Intel, is a high-performance processor
platform targeted for existing 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 440LX platform is based on the
PIIX4, a highly integrated version of Intel's PCI-to-ISA bridge family.

1-4PC 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,
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.
±5V,
±±
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.
and
±±
±12V
±±
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.
1-14
Chapter 1: Introduction
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.
1-15
SUPER 370SBA/370SBM/370SLA/370SLM User's Manual
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
1-6ACPI/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.
1-16
Chapter 1: Introduction
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.
1-17
SUPER 370SBA/370SBM/370SLA/370SLM User's Manual
1-7Power Supply Requirements
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 370SBA/370SBM/370SLA/370SLM accommodates ATX power supplies, and the 370SBM and 370SLM accommodates the new SFX 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 which 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 the
computer from noise. It is recommended that you also install a power surge
protector to help avoid problems caused by power surges.
1-8Super I/O
The disk drive adapter functions of 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 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 (16550
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 as well as an
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), 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.

2-1Static-Sensitive Devices
Static-sensitive electrical discharge 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 static discharge.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before you remove 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 system board and peripherals back into their antistatic bags when
not in use.
• For grounding purposes, be sure your computer system’s chassis provides
excellent conductivity between its power supply, the case, the mounting fasteners and the system board.
Unpacking
The system board is shipped in antistatic packaging to avoid static damage.
When unpacking the board, be sure the person handling the board is staticprotected.

2-4Mounting the Motherboard in the Chassis
All the motherboards have standard mounting holes to fit different types of
chassis. Chassis may come with a variety of mounting fasteners, made of
metal or plastic. Although a chassis may have both metal and plastic fasteners, metal fasteners are the most highly recommended because they ground
the system board to the chassis. Therefore, use as many metal fasteners as
possible for better grounding.

Use the following information to connect the floppy and hard disk drive cables.
• The floppy disk drive cable has seven twisted wires.
• A red mark on a wire typically designates the location of pin 1.
• A single floppy disk drive ribbon cable has 34 wires and two connectors to
provide for two floppy disk drives. The connector with twisted wires always
connects to drive A, and the connector without twisted wires always
connects to drive B.
• An IDE hard disk drive requires a data ribbon cable with 40 wires.
• A single IDE hard disk drive cable has two connectors to provide for two
drives. To select an IDE disk drive as C, you would normally set the
drive select jumper on the drive to DS1 (or Master). To select an IDE

AMIBIOS
4-1Introduction
This chapter describes the AMIBIOS for the Intel 440LX/BX Celeron 333-400 MHz
processors. The AMI ROM BIOS is stored in the Flash EEPROM and is easily
upgraded using a floppy disk-based program.
System BIOS
The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and
PS/2® compatible computers. WinBIOS is a high-quality example of a system
BIOS.
Configuration Data
AT-compatible systems, also called ISA (Industry Standard Architecture) must
have a place to store system information when the computer is turned off. The
original IBM AT had 64k bytes of non-volatile memory storage in CMOS RAM. All
AT-compatible systems have at least 64k bytes of CMOS RAM, which is usually
part of the Real-Time Clock. Many systems have 128k bytes of CMOS RAM.
How Data Is Configured
AMIBIOS provides a Setup utility in ROM that is accessed by pressing <Del> at
the appropriate time during system boot. Setup configures data in CMOS RAM.
POST Memory Test
Normally, the only visible POST routine is the memory test. The screen that
appears when the system is powered on is shown on the next page.
An AMIBIOS Identification string is displayed at the left bottom corner of the
screen, below the copyright message.

BIOS Error Beep Codes & Messages
During the POST (Power-On Self-Test) routines, which are performed each
time the system is powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue
the boot-up process. The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up
procedure. If a fatal error occurs, you should consult with your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of audible
beeps. The numbers on the fatal error list, on the following page, correspond
to the number of beeps for the corresponding error. All errors listed, with the
