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

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.

Chapter 1: Introduction

1-15

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.

Chapter 1: Introduction

1-17

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.

1-7 Power 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.

1-8 Super 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.

Chapter 1: Introduction

1-19

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 Super I/O complies with Microsoft PC98 Hardware Design Guide. IRQs,
DMAs and I/O space resources can flexibly adjust to meet ISA PnP require­ments. Moreover, it meets the specifications of PC98's power management
requirements: ACPI and APM (Advanced Power Management).

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.

2-4 Mounting 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.

2-5 Connecting Cables

After you have securely mounted the
motherboard to the chassis, you are
ready to connect the cables. Attach
a power supply cable to J32 for an

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
disk drive as D, you would normally set the drive select jumper on the
drive to DS2 (or Slave). Consult the documentation that came with your
disk drive for details on actual jumper locations and settings.

No Power

1. Make sure that the default jumper is on and the CPU is correctly set up.

2. Turn the power switch on and off to test the system.

3. If changing the jumper setting has not helped, clear CMOS.

4. Check the power supply voltage monitor. (Check the power supply 115V/
230V switch.)

No Video

Use the following steps to troubleshoot your system configuration.

1. If the power is on but you have no video, remove all the add-on cards and
cables.

2. Check for shorted connections, especially under the motherboard.

3. Check the jumpers settings, clock speed and voltage settings.

4. Use the speaker to determine if any beep codes exist. Refer to Appendix
A for details on beep codes.

NOTE

If you are a system integrator, VAR or OEM, a POST diagnostics

card is recommended. For port 80h codes, refer to Appendix B.

Memory Errors

If you encounter memory error, follow the procedures below.

1. Check to determine if the DIMM modules are improperly installed.

2. Make sure that different types of DIMMs have not been installed in different
banks (e.g., a mixture of 2MB x 36 and 1 MB x 36 DIMMs in Bank 0).

3. Determine if different speeds of DIMMs have been installed and verify that
the BIOS setup is configured for the fastest speed of RAM used. It is
recommended to use the same RAM speed for all DIMMs in the system.

4. Check for bad DIMM modules or chips.

5. Try to install the minimum amount of memory first (a single bank).

Losing the System’s Setup Configuration

1. Check the setting of jumper JBT1. Ensure that you are using a high
quality power supply. A poor quality power supply may cause the

3-3

Chapter 3: Troubleshooting

system to lose the CMOS setup information. Refer to Chapter 1 of this
manual for details.

2. If the above step does not fix the setup configuration problem, contact your
vendor for repairs.

3-2 Technical Support Procedures

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked
Question' (FAQ) sections in this chapter of the manual or check our web site
FAQ (http:// www.supermicro.com) before contacting Technical Support.

2. Take note that as a motherboard manufacturer, Super Micro does not sell
directly to end-users, so it is best to check with your distributor or reseller

SUPER 370SBA/370SBM/370SLA/370SLM User's Manual

3-3 Frequently Asked Questions

Question:

What are the differences between the various memories that

the 370SBA/370SBM/370SLA/370SLM motherboard can support?

Answer:

The 370SBA/370SBM integrates a main memory DRAM controller that

supports 64-bit or 72-bit (64 bits of memory data plus 8 ECC bits) DRAM from
8 MB to 512 MB for SDRAM and from 8 MB to 768 MB for EDO or registered
DIMMs. The DRAM types supported are either Extended Data Out (EDO),
Synchronous DRAM (SDRAM) or registered DIMM modules.

Note: EDO DIMMs are not recommended for running 100 MHz bus speed.

1. Mixing ECC and non-ECC will result in non-ECC operation. EC/ECC is
supported properly in the 440BX, only if all the memory is 72 bits wide.
A system with a mixture of 64 and 72-bit wide memory will disable the
ECC mode.

2. EDO memory and SDRAM cannot be mixed.

3. Registered SDRAM and unbuffered SDRAM cannot be mixed.

4. Mixing PC/100 DIMM and PC/66 DIMM will result in an unexpected
memory count or system errors.

5. User should populate the DIMMs starting with the DIMM socket located
the furthest from the BX chip.

6. If EDO memory is used, the CPU bus should be set at 66 MHz Bus speed
only.

Question:

How do I update my BIOS?

Answer:

It is recommended that you do not upgrade your BIOS if you are
experiencing no problems with your system. BIOS file updates are located on
our web site at http:// www.supermicro.com. Please check the current BIOS
revision and make sure it is newer than your BIOS before downloading. Select
your motherboard model and download the BIOS file to your computer. Unzip the
BIOS update file and you will find the readme.txt (flash instructions), the
sm2flash.com (BIOS flash utility), and the BIOS image (xxxxxx.rom) files. Copy
these files onto a bootable floppy and reboot your system. It is not necessary
to set BIOS boot block protection jumpers on the motherboard. At the DOS
prompt, enter the command "sm2flash." This will start the flash utility and give
you an opportunity to save your current BIOS image. Flash the boot block and
enter the name of the update BIOS image file. NOTE: It is important to save your
current BIOS and rename it "super.rom" in case you need to recover from a failed
BIOS update. Select flash boot block, then enter the update BIOS image. Select

3-5

Chapter 3: Troubleshooting

"Y" to start the BIOS flash procedure and do not disturb your system until the
flash utility displays that the procedure is complete. After updating your BIOS,
clear CMOS then load Optimal Values in the BIOS.

Question:

After flashing the BIOS my system does not have video. How

can I correct this?

Answer:

If the system does not have video after flashing your new BIOS, it
indicates that the flashing procedure failed. To remedy this, first clear CMOS per
the instructions in this manual and retry the BIOS flashing procedure. If you still
do not have video, please use the following BIOS recovery procedure. Turn your
system off and place the floppy disk with the saved BIOS image file (see above
FAQ) in drive A. Press and hold <CTRL> and <Home> at the same time, then
turn on the power with these keys pressed until your floppy drive starts reading.
Your screen will remain blank until the BIOS program is done. If the system
reboots correctly, then the recovery was successful.

Question:

I have memory problems. What is the correct memory to use

and which BIOS setting should I choose?

Answer:

The correct memory to use on the SUPER 370SBA/370SBM/370SLA/
370SLM is 168-pin DIMM 3.3v non-buffered SPD (Serial Present Detection)
SDRAM, SDRAM and EDO memory. SPD SDRAM is preferred but is not essen­tial. IMPORTANT: Please do not mix memory types; the results are unpredict­able. If your memory count is exactly half of the correct value, please go to the
BIOS in Chipset Setup and set "SDRAM AUTOSIZING SUPPORT" to

Enabled

.
Change between available options until one setting correctly displays your
memory.

Question:

Which Operating System (OS) supports AGP?

Answer:

At present, Windows 98 and Windows NT 5.0 are the only OS that have
built-in support for AGP. Some AGP video adapters can run Windows 95 OSR2.1
with special drivers. Please contact your graphics adapter vendor for more
details.

Question:

Do I need the CD that came with your motherboard?

Answer:

The supplied compact disc has quite a few drivers and programs that
will greatly enhance your system. We recommend that you review the CD and
install the applications you need. Applications included on the CD are PCI IDE
Bus Master drivers for Windows 95 and Windows NT, 440BX/LX chip set drivers
for Windows 95 and Super Doctor Monitoring software.

3-6

SUPER 370SBA/370SBM/370SLA/370SLM User's Manual

Question:

Why can't I turn off the power using the momentary power on/

off switch?

Answer:

The instant power off function is controlled by the BIOS. When this
feature is enabled in the BIOS, the motherboard will have instant off capabili­ties as long as the BIOS has control of the system. When this feature is
disabled or when the BIOS is not in control, such as during memory count (the
first screen that appears when the system is turned on), the momentary on/off
switch must be held for more than four seconds to shut down. This feature is
required to implement the ACPI features on the motherboard.

Question:

I see some of my PCI devices sharing IRQs, but the system

seems to be fine. Is this correct or not?

Answer:

Some PCI Bus Mastering devices can share IRQs without performance
penalties. These devices are designed to work correctly while sharing IRQs.

3-4 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required
before any warranty service will be rendered. You can obtain service by calling
your vendor for a Returned Merchandise Authorization (RMA) number. When
returning to the manufacturer, the RMA number should be prominently displayed
on the outside of the shipping carton, and mailed prepaid or hand-carried. Ship­ping and handling charges will be applied for all orders that must be mailed when
service is complete.

This warranty only covers normal consumer use and does not cover damages
incurred in shipping or from failure due to the alternation, misuse, abuse or
improper maintenance of products.

During the warranty period, contact your distributor first for any product prob­lems.

Chapter 4

AMIBIOS

4-1 Introduction

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.

Parameter Description

Type The number for a drive with certain identification parameters.

Cylinders The number of cylinders in the disk drive.

Heads The number of heads.

Write The size of a sector gets progressively smaller as the track

Precompensation diameter diminishes. Yet each sector must still hold 512 bytes.

Write precompensation circuitry on the hard disk compensates
for the physical difference in sector size by boosting the write
current for sectors on inner tracks. This parameter is the track
number where write precompensation begins.

Sectors The number of sectors per track. MFM drives have 17 sectors

per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.

Capacity The formatted capacity of the drive is (Number of heads) x

(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)

.

1st IDE-HDD, 2nd IDE-HDD, 3rd IDE-HDD and 4th IDE-HDD are the four
hard disks that can be installed by the BIOS. 1st IDE-HDD is the first hard
disk installed by the BIOS, 2nd IDE-HDD is the second hard disk, and so
on. For example, if the system has a hard disk connected to Primary Slave
and another hard disk to Secondary Master, then 1st IDE-HDD will be
referred to as the hard disk connected to Primary Slave and 2nd IDE-HDD
will be referred to as the hard disk connected to the Secondary Master.
3rd IDE-HDD and 4th IDE-HDD are not present. Note that the order of the
initialization of the devices connected to the primary and secondary
channels are Primary Master first, Primary Slave second, Secondary Master
third, and Secondary Slave fourth.

The BIOS will attempt to read the boot record from 1st, 2nd, 3rd and 4th
boot device in the selected order until it is successful in reading the booting
record. The BIOS will not attempt to boot from any device which is not
selected as the boot device.

Try Other Boot Device

This option controls the action of the BIOS if all the selected boot devices
failed to boot. The settings for this option are

Yes

or No. If

Yes

is
selected and all the selected boot devices failed to boot, the BIOS will try
to boot from the other boot devices (in a predefined sequence) which are
present but not selected as boot devices in the setup (and hence not yet

either a Supervisor password or a User password. If you do not want to use
a password, just press <Enter> when the password prompt appears.

The password check option is enabled in the Advanced Setup by choosing
either

Always

or

Setup

. The password is stored in CMOS RAM. You can
enter a password by typing the password on the keyboard, selecting each
letter via the mouse, or selecting each letter via the pen stylus. Pen access
must be customized for each specific hardware platform.

When you select Supervisor or User, AMIBIOS prompts for a password. You
must set the Supervisor password before you can set the User password.
Enter a 1-6 character password. The password does not appear on the screen
when typed. Retype the new password as prompted and press <Enter>.
Make sure you write it down. If you forget it, you must drain CMOS RAM and
reconfigure.

Note: The Optimal and Fail-Safe default settings for this option are
English.

5-4 Default Setting

Every option in WinBIOS Setup contains two default settings: a Fail-Safe
default, and an Optimal default.

Optimal Default

The Optimal default settings provide optimum performance settings for all
devices and system features.

Fail-Safe Default

The Fail-Safe default settings consist of the safest set of parameters. Use
them if the system is behaving erratically. They should always work but do not
provide optimal system performance characteristics.

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
exception of #8, are fatal errors.
