1-2 Chipset Overview

Intel's 820 chipset brings advanced technology to the performance PC plat­form. A 133 MHz front side bus speed, 4xAGP, RDRAM and increased I/O
performance are some of the new capabilities offered by the 820. The main
bridge of the 820 is the Memory Controller Hub (MCH), which enables a 133
or 100 MHz front side bus speed. An I/O Controller Hub (ICH) integrates PCI
peripherals and I/O functions with a dedicated 33 MHz PCI bus. An accel­erated hub interface provides a 266 MB/sec bandwidth between the MCH
and ICH and also separates the I/O devices from the MCH for improved
performance.

Memory Controller Hub (MCH)

The MCH consists of the host (CPU) interface, DRAM interface, I/O interface
and AGP interface for the 820 chipset. It supports ECC memory for RDRAM.
The AGP 2.0 interface supports 4x data transfer and 4x fast write capabil­ity. The MCH host interface bus runs at 133/100 MHz.

I/O Controller Hub (ICH)

The ICH is the I/O Controller Hub for the I/O subsystem, which integrates
many of the functions required by today's PC platforms. It provides the
interface to the PCI Bus and communicates with the MCH over a dedicated
hub interface.

Memory Translator Hub (MTH)

The Memory Translator Hub allows the PIIISCA/PIIISCD/370SCD to support
DIMM (SDRAM) type memory. Note for the PIIISCA: Only one type of
memory can be used; if RIMM(s) are installed, then any installed DIMM(s)
will be disabled. The MTH does not support ECC, meaning that the use of
ECC memory will result in non-ECC operation.

Introduction

Audio Modem Riser (AMR)

The AMR is a 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 FWH provides storage for 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
restoral happens in only ~5 seconds, applications that were open before
the sleep state can reopen 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 1-22 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 4-19 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
PIIISCA/PIIISCD/PIIISCE/370SCD. All three have an onboard System Hard

ware Monitor chip that supports PC health monitoring.

Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V,

±±

±±

±5V and

±±

±±

±12V

The onboard voltage monitor will scan these seven 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.

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
function in the BIOS (see page 4-18). This allows the user to define an
overheat temperature. When this temperature is exceeded, both the over­heat fan and the warning LED are triggered.

SUPER PIIISCA/PIIISCD/PIIISCE/370SCD User's Manual

1-22

Introduction

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.)

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.

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

Chapter 1: Introduction

1-23

Introduction

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 4-13).

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
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.

SUPER PIIISCA/PIIISCD/PIIISCE/370SCD User's Manual

1-24

Introduction

External Modem Ring-On

Wake-up events can be triggered by 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.

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 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. Wake­On-LAN must be enabled in BIOS (page 4-15). Note that Wake-On-Lan can
only be used with an ATX 2.01 (or above) compliant power supply.

1-5 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 high CPU clock rates of 300 MHz and above.

The SUPER PIIISCA/PIIISCD/PIIISCE/370SCD accommodates ATX power sup­plies. Although most power supplies generally meet the specifications re­quired by the CPU, some are inadequate.

It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.01 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.
Note: To support the keyboard wake-up function, your power supply must
be ATX 2.01 or higher and must provide a minimum standby voltage of 720
mA.

Chapter 1: Introduction

1-25

Introduction

It also 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. 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 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).

1-6 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.

2-1 Static-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 removing 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 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.

2-2

SUPER PIIISCA/PIIISCD/PIIISCE/370SCD 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 FAN1 header. Make sure that good contact is
made between the CPU and the heat sink, particularly with SECC2 Pentium
III OEM packages. Insufficient contact will cause the processor to
overheat, which may crash the system.

URM

Your motherboard has a preinstalled URM (Universal Retention Mecha­nism, not needed with 370SCD). A picture of a URM is shown in Figure
2-1. (This is one of several types - all of which can support SECC and
SECC2 packages.) Before installing your processor, you must flip the
arms of the URM to their upright positions. Some URMs may have extra
caps to be used for Pentium III processors (AMP URMs do not use these).
After the processor is installed in the motherboard, place one of these
caps (if included) on each end of the URM and push down until they
snap into place. These caps are not left/right specific.

Processor

370SCD:

Your motherboard has an FCPGA type socket, which supports Flip Chip
processors. Lift the lever on the FCPGA socket and install with the notched
corner of the processor oriented with pin 1. Fully seat the processor into
the socket and then close the lever.

2-2 Processor Installation

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

The following pages cover the installation procedure. You should install the
processor to the motherboard first, then install the motherboard in the chassis,
then the memory and add-on cards, and finally the cables and drivers. Following
the installation procedures in the order they appear in this chapter 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.

*Note: The Pentium II processor comes in the SECC package, which has
locking tabs on the top corners. Before installing the Pentium II package into
the URM, push these two locks inward until you hear a click. (After you
have fully seated the processor into the Slot 1 connector as instructed
below, these locks should return to their outer positions.)

With the heat sink facing toward the RIMM/DIMM memory slots, slide the
SECC/SECC2 processor package into the URM and continue pushing it down
until fully seated in the Slot 1 connector. Some URMs have extra caps to be
used for SECC2 processors (AMP URMs do not have these). If so, after the
processor is installed in the motherboard, place a cap on each end of the
URM and push down until they snap into place. These caps are not left/
right specific.

PIIISCA/PIIISCD/PIIISCE:

Your motherboard has a Slot 1 type connector, which supports Pentium II*
and Pentium III processors housed in SECC* and SECC2 packages, respec­tively. Please see the note below when installing a Pentium II processor
with the SECC package.

2-4 Installing RIMMs/DIMMs

CAUTION

Exercise extreme care when installing or removing RIMM/DIMM

modules to prevent any possible damage. Also note that

continuity modules must be installed into empty RIMM slots.

RIMM/DIMM Installation (See Figure 2-2)

1. Insert RIMMs/DIMMs as required for the desired system memory. See
note below for single module installation.

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

3. Gently press down on the RIMM/DIMM module until it snaps into place in
the slot.

Note: Continuity modules

must

be installed in empty RIMM slots on the

PIIISCA/PIIISCE.

Note: Single module installation

If installing only a single DIMM, you may use either DIMM Bank 1 or 0.
If installing only a single RIMM module, it must be installed in the
RIMM slot nearest to the CPU slot and continuity modules must be installed
in all RIMM slots that remain empty.

Note: Changing memory types

When changing memory from SDRAM (DIMMs) to RDRAM (RIMMs) or vice
versa, you must first disconnect the AC Power cable and then use JBT1
to clear CMOS (see page 2-12).

2-3 Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Chassis may include a variety of mounting fasteners made of
metal or plastic. Although a chassis may have both types, metal fasteners
are the most highly recommended because they ground the motherboard to
the chassis. For this reason, it is best to use as many metal fasteners as
possible.

on the PIIISCA/PIIISCD/370SCD. The MTH does not support ECC. ECC
type memory may be used, but will result in non-ECC operation. (See
page 1-19 for more info on the MTH.)

The Memory Controller Hub (MCH) enables the use of RDRAM in the RIMM
slots on the PIIISCA/PIIISCE. This hub supports both ECC and non-ECC
type memory. Check the Memory ECC Mode BIOS setting on page 4-11 to
enable the use of ECC. (See page 1-19 for more info on the MCH.)

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.

Changing the CPU
Speed

Changing the CPU speed is en­abled by software control in BIOS
(see CPU Speed on page 4-9 and
CPU Clock Frequency on page 4-

11). The CPU Speed setting will
show you the actual CPU speed
for each FSB speed option se­lected. The CPU Clock Frequency
setting will show you additional
FSB speed options. The FSB
speed is set with JP12. See Table
2-16 for jumper settings. Note: If
the system does not reboot after
changing the CPU speed, clear
CMOS and reboot then set the cor­rect speed with the BIOS setting
mentioned above. (See CMOS

SUPER PIIISCA/PIIISCD/PIIISCE/370SCD User's Manual

Troubleshooting

5. Install a single memory module and make sure it is fully seated.

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

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 1-20 for
details.

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 repair.

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 end­users, 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 web site

NOTE

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

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

Memory Errors

1. Make sure the DIMM/RIMM modules are properly and fully installed.

2. Determine if different speeds of DIMMs/RIMMs 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/RIMMs in the system.

3. For DIMMs, make sure you are using PC 100 compliant, unbuffered
SDRAM. EDO and buffered SDRAM are not supported.

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

3-3

3-3 Frequently Asked Questions

Question: What are the various types of memory that the PIIISCA/
PIIISCD/PIIISCE/370SCD motherboard can support?

Answer: The PIIISCA, PIIISCDand 370SCD have two DIMM slots that sup-

port 168-pin, unbuffered 3.3V SDRAM. They do not support ECC or EDO
memory. Note that whether running at 100 or 133 MHz FSB speed, the
memory must be PC100 compliant. Because ECC is not supported, using
ECC memory will result in non-ECC operation. The PIIISCA also has 2 RIMM
sockets, as does the PIIISCE. Use 300/400 MHz (600/800 MB/sec) RIMM
modules for RDRAM. ECC and non-ECC RDRAM are both supported. Check
the Memory ECC Mode BIOS setting on page 4-11 to enable the use of ECC.
Note: Continuity modules

must

be installed into empty RIMM slots. If both

RIMMs and DIMMs are installed, the DIMMs will be disabled.

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 included on the CD

3-5

Chapter 3: Troubleshooting

Troubleshooting

are 820 chipset drivers for Windows9x, audio drivers and Super Doctor
Monitoring software.

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 (see page 4-11). 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.

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 perfor-

mance penalties. These devices are designed to work correctly while shar­ing IRQs. See Table 3-1 below for details on shared IRQs.

Question: I installed my microphone correctly but I can't record any
sound. What should I do?

Answer: Go to <Start>, <Programs>, <Accessories>, <Entertainment> and

then <Volume Control>. Under the Properties tab, scroll down the list of
devices in the menu and check the box beside "Microphone".

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMIBIOS for Intel 820 Pentium II/III 350-733 MHz
and Pentium III FCPGA 500-700 MHz processors. The AMI ROM BIOS is
stored in a Flash EEPROM and can be easily upgraded using a floppy disk­based program.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®,
and PS/2® compatible computers.

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 64 kbytes of non-volatile memory storage in
CMOS RAM. All AT-compatible systems have at least 64 kbytes of CMOS
RAM, which is usually part of the Real Time Clock. Many systems have 128
kbytes 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.

Entering Drive Parameters

You can also enter the hard disk drive parameters. The drive parameters are:

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

Bit 5 of the command register in the PCI device configuration space is the
VGA Palette Snoop bit (0 is disabled). For example: if there are two
VGA devices in the computer (one PCI and one ISA) and this option is
disabled, data read and written by the CPU is only directed to the PCI
VGA device's palette registers. If enabled, data read and written by the
CPU is directed to both the PCI VGA device's palette registers and the
ISA VGA palette registers. This will permit the palette registers of both
devices to be identical. This option must be set to

Change User Password

Change Supervisor Password

The system can be configured so that all users must enter a password
every time the system boots or when the AMIBIOS setup is executed.
You can set 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.

Chapter 4: BIOS

4-21

BIOS

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 it out on the keyboard or by

selecting each letter via the mouse or a pen stylus. Pen access must be
customized for each specific hardware platform.

When you select to change the Supervisor or User password, AMIBIOS
prompts you for the new password. You must set the Supervisor
password before you can set the User password. Enter a 1-6 character
password. (It will 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 clear CMOS RAM and reset the pass­word.

Change Language Setting

Because this version of BIOS only supports English at this time, this setting
cannot be chosen. Future releases may support other languages.

Auto Configuration with Optimal Settings

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

Auto Configuration with Fail Safe Settings

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.

Save Settings and Exit

Highlight this and hit <Enter> when you wish to save any changes made to
settings in BIOS and exit back to the system boot-up procedure.

Exit Without Saving

Highlight this and hit <Enter> when you wish to exit back to the system
boot-up procedure without saving any changes.

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.
