PREFACE
About This Manual

This manual is written for system integrators, PC technicians and
knowledgeable PC users. It provides information for the installation and use
of the SUPER 370DE6/370DER(370DER+)/370DEI(370DEI+) mainboard. The
SUPER 370DE6/370DER/370DER+/370DEI/370DEI+ supports single or dual
Pentium® III 500 MHz-1.13 GHz FCPGA processors with a 133/100 MHz
front side bus. Please refer to the support section of our web site (http://
www.supermicro.com/TechSupport.htm) for a complete listing of supported
processors.

Pentium III FCPGA (Flip Chip Pin Grid Array) processors are housed in a
370-pin socket, which is the standard that will support future Intel proces­sors. The 370DER/370DER+/370DEI/370DEI+ were designed specifically for
use in rackmount 1-U systems.

Manual Organization

Chapter 1 includes a checklist of what should be included in your

mainboard box, describes the features, specifications and performance of
the SUPER 370DE6/370DER/370DER+/370DEI/370DEI+ mainboard and pro­vides detailed information about the chipset.

Chapter 2 begins with instructions on handling static-sensitive devices.
Read this chapter when you want to install the processor and DIMM memory
modules and when mounting the mainboard in the chassis. Also refer to
this chapter to connect the floppy and hard disk drives, SCSI drives, the IDE
interfaces, the parallel and serial ports and the twisted wires for the power
supply, the reset button, the power LED, the speaker and the keyboard.

If you encounter any problems, see Chapter 3, which describes trouble­shooting procedures for the video, the memory and the setup configuration
stored in CMOS. For quick reference, a general FAQ [Frequently Asked
Questions] section is provided. Instructions are also included for contact­ing technical support. In addition, you can visit our web site at
www.supermicro.com/techsupport.htm for more detailed information.

Chapter 4 includes an introduction to BIOS and provides detailed informa­tion on running the CMOS Setup utility.

Appendix A gives information on BIOS error beep codes.

Appendix B provides post checkpoint codes.

Introduction

1-2 Chipset Overview

The ServerWorks ServerSetTM III HE SL is a high-performance core logic
chipset that consists of a North Bridge and a South Bridge.

The North Bridge integrates the main memory subsystem and a dual channel
PCI bus and bridges the processor bus to a 64-bit PCI bus. The memory
subsystem consists of a two-way interleaved 4-DIMM configuration ac­cessed over a 144-bit memory bus (most chipsets have a 72-bit memory
bus), which provides a significant boost in performance. The North Bridge
also packs and unpacks data for PCI accesses to reserve more processor
bandwidth for multiprocessor motherboards.

The South Bridge provides various integrated functions, including the PCI to
ISA bridge and support for UDMA33, security (passwords and system pro­tection), Plug & Play, USBs, power management, interrupt controllers and
the SMBus.

1-3 Special Features

ATI Graphics Controller (370DER/DER+/370DEI only)

The 370DER/370DER+/370DEI has an integrated ATI video controller based
on the Rage XL graphics chip. The Rage XL fully supports sideband ad­dressing and AGP texturing. This onboard graphics package can provide a
bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus.

BIOS Recovery

The BIOS Recovery function allows you to recover your BIOS image file if
the BIOS flashing procedure fails (see Section 3-3).

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 Advanced BIOS Setup
section (Peripheral Device Configuration) to change this setting. The de­fault setting is Always On.

Introduction

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
370DE6/370DER/370DER+/370DEI. These motherboards have an onboard
System Hardware Monitor chip that supports PC health monitoring.

Onboard Voltage Monitors for the CPU Core, Chipset Voltage,
+5V and +12V

The onboard voltage monitor will scan these voltages continuously. The
370DE6 also monitors +3.3V. Once a voltage becomes unstable, a warning
is given or an error message is sent to the screen. Users can adjust the
voltage thresholds to define the sensitivity of the voltage monitor.

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.

SUPER 370DE6/370DER/370DEI User's Manual

1-26

Introduction

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 that prevents viruses from
infecting 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 1.4V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.

1-5 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 lever-

Chapter 1: Introduction

Introduction

ages 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. Note: To utilize ACPI, you must reinstall Windows 98. To reinstall
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.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a
system suspend button to make the system 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. This option can be set in the Power section of the BIOS Setup
routine.

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.

Introduction

Wake-On-LAN (WOL) (not on 370DEI)

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 CPU clock rates.

The SUPER 370DE6/370DER/370DER+/370DEI accommodates ATX power
supplies. Although most power supplies generally meet the specifications
required by the CPU, some are inadequate. You should use one that will
supply at least 300W of power - an even higher wattage power supply is
recommended for high-load configurations. Also your power supply must
provide a +5V standby voltage that supplies at least 720 mA of current. But
for the 370DE6, 1.5A is needed for LAN1 and LAN2.

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.

1-7 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 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.It also

Chapter 1: Introduction

provides two high-speed, 16550 compatible serial communication ports
(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.
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 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).

2-1 Static-Sensitive Devices

Electric-Static-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 grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the anti-

static 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 between 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.

SUPER 370DE6/370DER/370DEI User's Manual

Installation

Heat Sink

Follow the instructions that came with your processor or heat sink to attach
a heat sink to the processor. Your heat sink should have a 3-pin fan, which
connects to the CPU FAN header. Make sure that good contact is made
between the CPU chip (the die) and the heat sink. Insufficient contact or
inproper types of heat sinks, thermal compound, and fans can cause the
processor to overheat, which may crash the system. (You can check the
CPU temperature readings in the "Periperal Setup" Section of BIOS.)

Processor

Your motherboard has two 370-pin sockets, which support Intel FCPGA
processors. Lift the lever on the FCPGA socket and insert the processor
with the notched corner oriented toward pin one on the socket. Make sure
the processor is fully seated in the socket and and then close the lever.
You can also install a single 370-pin FCPGA CPU on a dual-processor moth­erboard without changing any jumper settings. See Figure 2-1 for views of
the 370-pin FCPGA socket before and after processor installation.

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of chassis.
Make sure the location of all the mounting holes for both the motherboard and
the chassis match. Although a chassis may have both plastic and metal mount­ing fasteners, metal ones are highly recommended because they ground the
motherboard to the chassis. Make sure the metal standoffs click in or are

2-2 FCPGA Processor Installation

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

This section covers the installation procedure for FCPGA (Flip Chip Plastic
Grid Array) type processors. You should install the processor first and
then install the motherboard in the chassis. Following the installation proce­dures in the order they appear in this section should eliminate the most
common problems encountered when installing a system.

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

2-3 Installing DIMMs

NOTE: Check the Supermicro web site for recommended memory
modules:

http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also note that the

memory is interleaved to improve performance (see step 1).

DIMM Installation (See Figure 2-2)

1. Insert either two or four DIMMs as required for the desired system
memory. Two-way interleaved memory requires that memory
modules be installed in pairs(-first in the two slots of Bank0 and
then in both slots of Bank1, if
needed).

2. Insert each DIMM module vertically into its slot. Pay attention to the
two notches along the bottom of the module to prevent inserting the
DIMM module incorrectly.

3. Gently press down on the DIMM module until it snaps into place in the
slot. Repeat for all modules (see step 1 above).

Support

The 370DE6/370DER/370DER+ only supports ECC registered SDRAM
memory. PC133 and PC100 memory are both supported at their respec­tive speeds. However, the memory bus is synchronized to the front side
bus speed, so using PC100 with a 133 MHz FSB or using PC133 with a
100 MHz FSB, will result in 100 MHz memory speed operation in either
case.

2-7 Jumper Settings

Explanation of
Jumpers

To modify the operation of the
motherboard, jumpers can be
used to choose between
optional settings. Jumpers
create shorts between two pins
to change the function of the
connector. Pin 1 is identified
with a square solder pad on
the printed circuit board. See
the motherboard layout pages
for jumper locations. Note: On
two pin jumpers, "closed"
means the jumper is on and
"open" means the jumper is off

the pins.

2-6 DIP Switch Settings

DIP Switch 1:
Core/Bus Ratio

A red "DIP" switch labeled SW1 is
located on the 370DE6/370DER/
370DER+/370DEI. SW1 has four
individual switches, which are
used to set the core/bus ratio.

The example on the right will show
you which CPU Core/Bus Ratio to
use. The general rule is to divide
the CPU speed by the bus speed.
If you have a 550 MHz CPU, divid­ing it by a 100 Mhz front side bus
will give you a CPU Core/BUS Ra­tio of 5.5. After determining the
CPU Core/Bus Ratio, refer to Table
2-22 for the correct settings of DIP
Switch 1.

Note: Most Intel processors have

a fixed Core/Bus ratio that will
overwrite the setting of DIP Switch

1.

550 (MHz) / 100 (MHz) = 5.5

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have
followed all of the procedures below and still need assistance, refer to the
‘Technical Support Procedures’ and/or ‘Returning Merchandise for Service’
section(s) in this chapter.

Note: Always disconnect the power cord before adding, changing
or installing any hardware components.

Before Power On

1. Make sure no short circuits exist between the motherboard and
chassis.

2. Disconnect all ribbon/wire cables from the motherboard, including those
for the keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis
speaker and the power LED to the motherboard. (Check all jumper
settings as well.)

No Power

1. Make sure no short circuits exist between the motherboard and the
chassis.

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

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

5. The battery on your motherboard may be old. Check to verify that it
still supplies ~3VDC. If it does not, replace it with a new one.

No Video

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

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

SUPER 370DE6/370DER/370DEI User's Manual

Troubleshooting

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
system to lose the CMOS setup information. Refer to page 1-19 for
details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it
still supplies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not fix the Setup Configuration problem, contact
your vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also,
note that as a motherboard manufacturer, Super Micro does not sell directly
to end-users, so it is best to first check with your distributor or reseller for
troubleshooting services. They should know of any possible problem(s)
with the specific system configuration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently
Asked Question' (FAQ) sections in this chapter or see the FAQs on our

NOTE

If you are a system integrator, VAR or OEM, a POST diagnos-

tics card is recommended. For I/O port 80h codes, refer to

App. B.

Memory Errors

1. Make sure the DIMM modules are properly and fully installed in pairs.

2. 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.

3. Make sure you are using PC133 or PC100 compliant, registered ECC,
SDRAM. EDO SDRAM is not supported.

4. Check for bad DIMM modules or slots by swapping a single module
between two slots and noting the results.

5. Make sure all memory modules are fully seated in their slots.

6. Check the power supply voltage 115V/230V switch.

Answer: The370DE6/370DER/370DEI has four DIMM slots that support 168-

pin, registered ECC DIMMs ECC only. Unbuffered SDRAM or non-ECC
memory is not supported. PC133 and PC100 memory are both fully sup­ported at their respective speeds. Important: The memory employs a

two-way interleaving scheme, which requires you to install
memory modules in pairs (-first in the two slots of Bank0, and
then, in both slots of Bank1, if needed.)

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. Updated BIOS files are located
on our web site at http://www.supermicro.com. Please check our BIOS
warning message and the info on how to update your BIOS on our web
site. Also, 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 fwhflash.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 "fwhflash." 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 "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, please clear the 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. First,
make sure the JPWAKE jumper is disabled. Then, 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. The BIOS Recovery
Procedure will not update the boot block in your BIOS.

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 on the CD include
chipset drivers for Windows and security and audio drivers.

Troubleshooting

Question: Why can't I turn off the power using the momentary
power on/off switch?

Answer: The instant power off function is controlled in BIOS by the Power

Button Mode setting. When the On/Off feature is enabled, the motherboard

will have instant off capabilities as long as the BIOS has control of the
system. When the Standby or Suspend feature is enabled 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 the system. This feature
is required to implement the ACPI features on the motherboard.

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.

4-1 Introduction

This chapter describes the AMIBIOS for the 370DE6/370DER/370DER+/
370DEI/370DEI+. The AMI ROM BIOS is stored in a Flash EEPROM and can
be easily upgraded using a floppy disk-based program.

Note: Due to periodic changes to BIOS, some settings may have been
added or deleted and might not yet be recorded in this manual. Refer to the
Manual Download area of our web site for any changes to BIOS that are
not reflected in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®,
and PS/2® compatible computers. The BIOS ROM stores the system param­eters, such as amount of memory, type of disk drives and video displays,
etc. BIOS ROM requires very little power. When the computer is turned off,
a back-up battery provides power to the BIOS ROM, enabling it to retain the
system parameters. Each time the computer is powered-on, the computer is
then configured with the values stored in the BIOS ROM by the system
BIOS, which gains control when the computer is powered on.

How To Change the Configuration Data

The configuration data that determines the system parameters may be
changed by entering the BIOS Setup utility. This Setup utility can be ac­cessed by pressing <Del> at the appropriate time during system boot.

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory
test. As the memory is being tested, press the <Delete> key to enter the
main menu of the BIOS Setup utility. From the main menu, you can access
the other setup screens, such as the Chipset and Power menus. Section 4­3 gives detailed descriptions of each parameter setting in the Setup utility.

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 exception of Beep Code 8, are fatal errors.
