Chapter 1: Introduction

Introduction

1-2 Chipset Overview

Intel’s 815 chipset is made up of three main components: the Graphics and
Memory Controller Hub (GMCH), the I/O Controller Hub (ICH) and the Firm­ware Hub (FWH). The GMCH integrates a 133/100/66 MHz system bus
controller, a 2D/3D graphics accelerator (AGP2x/4x) discrete graphics card,
a 133/100 MHz SDRAM controller and a high-speed hub architecture inter­face that communicates with the ICH. The ICH integrates a UDMA/100 or
UDMA/66 controller, USB controllers and other I/O functions (see below).
The FWH stores both system and video BIOS and includes a Random Num­ber Generator (RNG).

Graphics and Memory Controller Hub (GMCH)

The GMCH includes the host (CPU) interface, DRAM interface, ICH interface
and 4xAGP interface for the 815 chipset. It contains advanced power
management logic and supports dual channels for DRAM. The AGP 2.0
interface supports 4x data transfers and operates at a peak bandwidth of
266 MB/sec. The MCH host interface bus runs at 133/100/66 MHz.

I/O Controller Hub (ICH/ICH2)

The ICH is the I/O Controller Hub subsystem on the 370SSM, which inte­grates many of the Input/Output functions of the 815 chipset, including a
two-channel UDMA/66 Bus Master IDE controller. It also provides the inter­face to the PCI Bus and communicates with the MCH over a dedicated hub
interface. The 370SSA has the more powerful ICH2, which includes UDMA/
100 IDE controllers and two USB controllers that offer 24 Mbps of band­width across four ports. ICH2 also features an enhanced AC'97 interface
that supports full surround sound for the Dolby Digital Audio used on DVDs.

Firmware Hub (FWH)

The FWH is a component that brings added security and manageability to
the PC platform infrastructure. This device includes an integrated Random
Number Generator (RNG) for stronger encryption, digital signing and secu­rity protocols. The FWH stores the system BIOS and video BIOS to eliminate
a redundant nonvolatile memory component.

SUPER 370SSA/370SSM User's Manual

Introduction

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 BIOS chapter of this
manual to change this setting. The default setting is Always OFF.

1-3 Special Features

Communication and Networking Riser (CNR - 370SSA only)

The CNR slot supports audio, modem and networking cards and provides
interfaces that support multichannel audio, V.90 analog modems, home net­working through a telephone line, 10/100 Ethernet-based networking and
future technologies. Separating sound and communications systems from
the motherboard makes them less sensitive to noise.

Audio Modem Riser (AMR - 370SSM only)

The AMR is a new 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.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
370SSA/370SSM. Both have an onboard System Hardware 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.

Chapter 1: Introduction

1-15

Introduction

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. 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.

SUPER 370SSA/370SSM User's Manual

Introduction

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.

1-5 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 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. 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.

quests.

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, it keyboard will
function 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.

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.

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.

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 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.

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. 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 high CPU clock rates of 300 MHz and above.

The SUPER 370SSA/370SSM 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 2.02 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.

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 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

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 370SSA/370SSM 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 and the heat sink. Insufficient
contact will cause the processor to overheat, which may crash the
system.

Processor

You are now ready to install the processor. Your motherboard has a 370­pin, FCPGA type socket, which supports 370-pin Pentium III FCPGA (not
SEPP) and Celeron PPGA 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. See
Figure 2-1 for views of the FCPGA 370-pin socket before and after proces­sor installation.

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 in 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.

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.

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage.

DIMM Installation (See Figure 2-2)

1. Insert DIMMs in Bank 0 through Bank 2 as required for the desired
system memory.

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 incorrectly.

3. Gently press down on the DIMM module until it snaps into place.

4. If installing only a single DIMM, you may use any Bank. The 370SSA/
370SSM will support a total of 512 MB of unbuffered SDRAM in its
three DIMM slots. ECC type memory is not supported. PC133 and
PC100 memory are both fully supported at their respective speeds.
However, if three DIMM modules are installed, the memory will run at
100 MHz, even if PC133 memory is used (this is a chipset limitation).

To Install:

Insert module
vertically and
press down
until it snaps
into place.
Pay attention
to the two
notches.

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 that does not have twisted wires
always connects to drive B.

• The 80-wire ATA66/100 (370SSM/370SSA) IDE hard disk drive cable that
came with your system has two connectors to support two drives. This
special cable should be used to take advantage of the speed this new
technology offers. The blue connector connects to the onboard IDE
connector interface and the other connector(s) to your hard drive(s).
Consult the documentation that came with your disk drive for details on
actual jumper locations and settings for the hard disk drive.

Keyboard Wake-Up

The JPWAKE jumper is used to­gether with the Keyboard Wake­Up function in BIOS. Enable both
the jumper and the BIOS setting to
allow the system to be woken up
by depressing a key on the key­board. See Table 2-20 for jumper

AGP Pro Slot

The AGP Pro slot is backward compatible with AGP and 4xAGP graphics
cards, which have fewer pins than AGP Pro cards. Because of this,
care must be taken when installing a graphics card into this slot, as doing
so incorrectly can damage your motherboard. For AGP Pro cards, you
should remove the orange sticker covering one end of the slot. For other
cards, leave this sticker in place and make sure your card does not plug
into the section it covers. A general rule of thumb is to make sure your
card fills the center section of pins first, then the end toward the edge of
the motherboard if there are more. If the I/O shield of your card is flush
with the edge of the motherboard, the card should be inserted correctly.

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, Supermicro 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.

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 for the
amount of memory desired.

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

3. For DIMMs, make sure you are using PC133 or PC100 compliant,
unbuffered SDRAM. EDO SDRAM is not supported.

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

3-3 Frequently Asked Questions

Question: What are the various types of memory that the 370SSA/
370SSM motherboard can support?

Answer: The 370SSA/370SSM has three 168-pin DIMM slots that support

up to 512 MB of unbuffered 3.3V SDRAM (registered DIMMs not supported).
ECC memory is not supported. The 133/100 MHz memory bus fully supports
both PC133 and PC100 memory. However, if three DIMM modules are in­stalled, the memory will run at 100 MHz, even if PC133 memory is used (this
is a chipset limitation).

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 down-

Troubleshooting

load 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 Recov-
ery 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
815 chipset drivers for Windows and security and audio drivers.

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.

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.

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.

Question: How do I connect the ATA66/100 cable to my IDE
device(s)?

Answer: The 80-wire/40-pin ATA66/100 IDE cable that came with your

system has two connectors to support two drives. This special cable must
be used to take advantage of the speed the ATA66/100 technology offers.
Connect the blue connector to the onboard IDE header and the other
connector(s) to your hard drive(s). Consult the documentation that came
with your disk drive for details on actual jumper locations and settings.
(The 370SSM has an ATA66 cable and the 370SSA has an ATA100 cable.)

4-1 Introduction

This chapter describes the AMIBIOS for the 370SSA/370SSM. 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.

Enabled: This option overrides RAS-to-CAS. SDRAM stores informa
tion in blocks of rows and columns. RAS stands for Row Address
Strobe. CAS stands for Column Address Strobe.

CAS Latency

This option regulates the speed of the Column Address Strobe (CAS)
as either Fast or Slow, which is higher or lower latency. CAS latency
optimizes the speed at which data is accessed in a column by defining
CAS latency time in 100 MHz or 133 MHz clocks (dependent on the
memory bus speed). It controls the time delay (in clocks) before
SDRAM starts a read command after receiving it. Reading RAS data
can be read twice as fast as reading CAS. Lowering the latency can
increase the speed of the SDRAM, but at the expense of stability.

ACPI Aware O/S

This option allows the system to utilize Intel's ACPI (Advanced Configuration
and Power Interface) specification. Settings are No and Yes. DOS®,
Windows 3.x®, and Windows NT® are examples of non-ACPI aware oper­ating systems. Windows 95®, Windows 98® and Windows 2000® are
examples of ACPI aware operating systems.

Suspend to RAM Support

This allows you to enable or disable the Suspend to RAM feature. Settings
are Disabled and Enabled. The Disabled setting prevents the system from
saving information to main memory when in a low power state. Enabled
causes the system to enter a low power state instead of being completely
shut off. This allows the computer system to bootup in a few seconds.
Suspend to RAM (STR) is a technology that is closely associated with the
S3 state of the ACPI (Advanced Configuration and Power Interface) speci­fication. STR allows a properly configured system to go into a low power
state while saving information to main memory about the system’s configu­ration, open applications, and active files. While in the low power (STR)
state, memory remains powered to retain the system information while most
other components turn off to conserve energy. Fans are turned off to pro­vide silent operation and to minimize power consumption. Properly config­ured systems in STR typically can consume less than 5 watts.

Repost Video on S3 Resume

This option determines whether or not to invoke the VGA BIOS post test
when resuming from STR or the S3 state. Settings are No and Yes. (Used
with ACPI only.)

Power Management /APM

This option allows you to select using APM (Advanced Power Manage­ment). The settings are Disabled and Enabled.

This option specifies the length of system inactivity time that should expire
before the computer enters a standby power state. The settings are Dis-
abled, 1Min, 5Min and 10Min.

Chapter 4: BIOS

BIOS

After G3 Enable

This option allows AfterG3 Enable support. The settings are Disabled and
Enabled. Disabled prevents the system to power on after power is applied
to the system. Enabled allows the system to power on after power is
applied to the system. This means that if an ATX compliant power supply is
turned hard off or unplugged from the wall (power socket supplying it
power), the computer system will not power back on immediately after the
power cord is reattached or the hard off switch is flipped back on. The
power button on the front of the chassis is usually the soft off, meaning
that there is still power being supplied to the motherboard even though the
system looks completely off. Hard off means that there is not power being
supplied to the system at all. The only power is coming from the backup
battery on the motherboard.

Suspend Power Saving Type

The settings for this option are C2 and S1. The C2 setting allows the CPU
(microprocessor) to be put in a low power state. In this state, incoming
interrupts wake-up the CPU (microprocessor) to process them (I/O APIC).
S1 allows the system to enter the S1 POS (Power On Suspend) state.
While the system is in this state, the CPU is not executing instructions, all
power resources that supply system level reference of S0 are off, system
memory context is maintained, devices that reference power resources that
are on are on, and devices that can wake-up the system can cause the
CPU to continue to execute from where it left off.

Suspend Time Out

This option specifies the length of system inactivity while in the standby
state that should expire before the computer enters a suspend power state.
The settings are Disabled, 1Min, 5Min and 10Min.

Power Button Mode

This option specifies how the external power button on the computer chas­sis functions. When set to On/Off, depressing the power button turns the
computer on or off. When set to Suspend, depressing the power button
places the computer in Suspend mode or Full On power mode. The Standby
setting places the computer in Standby or Full On mode.

This option specifies if BIOS is to monitor for display activity when in a
power saving state. The Ignore setting means any display activity will not
wake the system up from a power management state. The Monitor setting
allows display activity to wake up the system from a power management
state.

Manual Throttle Ratio

When in a power management state, throttling can be used to lower power
consumption and reduce heat. This option allows the CPU to operate at a
reduced average power, which includes a sacrifice in performance. The
settings include 87.5%, 75.0%, 62.5%, 50%, 37.5%, 25% and 12.5%. (A
setting of 75.0% means the BIOS will throttle back the CPU clock to operate
75% of the time.)

Intruder Sel

This option allows you to set the Intruder SEL setting to SCI or SMI. SCI
stands for System Control Interrupt. This is considered to be ACPI (Ad­vanced Configuration and Power Interface) mode. The operating system
uses the SCI interrupt to process ACPI (Advanced Configuration and Power
Interface) events signaled by GPEs (general Purpose Event), whether the
system is asleep or awake when the event occurs. In other words, the
wake event has the side effect of causing the system to wake up if it is
asleep, but its primary purpose is to generate an SCI that notifies the oper­ating system that the event has occurred. SMI stands for System Manage­ment Interrupt. This is considered to be Legacy mode. It is used to log
interrupt events to operating systems that do not support ACPI (Advanced
Configuration and Power Interface) and operating systems that do.

Supervisor Password

User Password

AMIBIOS provides both Supervisor and User password functions. If you
use both passwords, the Supervisor password must be set first. The sys­tem can be configured so that all users must enter a password every time
the system boots or when AMIBIOS Setup is executed, using either or both
the Supervisor password or User password. The Supervisor and User
passwords activate two different levels of password security. If you select
password support, you are prompted for a 1 – 6 character password. Type
the password on the keyboard. The password does not appear on the
screen when typed. Make sure you write it down. If you forget it, you must
clear CMOS and reconfigure. Remember your Password! Keep a record
of the new password when the password is changed. If you forget the
password, you must erase the system configuration information in CMOS.

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.
