Chapter 1: Introduction

1-15

1-2 Chipset Overview

Intel’s 815E B-Step 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 ICH2. The ICH2 inte­grates a UDMA/100 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, ICH2 inter­face and 4xAGP interface for the 815/815E 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 (ICH2)

The P3TSSA/P3TSSR/P3TSSE is based on the 815E B-Step chipset and has
the more powerful ICH2, which includes UDMA/100 IDE controllers and two
USB controllers that offer 24 Mbps of bandwidth across four USB 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 both the system BIOS and video BIOS
thereby eliminating a redundant nonvolatile memory component.

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

SUPER P3TSSA/P3TSSR/P3TSSE User's Manual

1-16

power switch to turn it back on) or for it to automatically return to a power­on state. See the "Power Loss 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 (P3TSSA 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, Ethernet 10/100 T-base networking and
future communications technologies.
Separating the sound and communications systems from the motherboard
makes them less sensitive to noise.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
P3TSSA/P3TSSR/P3TSSE.

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

++

++

+5v and

±±

±±

±12v

The onboard voltage monitor scans 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.

Chapter 1: Introduction

1-17

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 allowing it to continue to monitor for overheat conditions 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

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 of 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 99 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 automatically to turn peripherals, such as
CD-ROMs, network cards, hard disk drives and printers, on and off. This
feature 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, Windows NT and Windows 2000. 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.

Chapter 1: Introduction

BIOS Support for USB Keyboard

If a USB keyboard is the only keyboard in the system, it can be set to
function as 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 four seconds. The power will turn
off and the main power will not 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.

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.

1-7 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 KB, 720 KB, 1.2 MB, 1.44 MB or

2.88 MB disk drives and data transfer rates of 250 Kbps, 500 Kbps or 1
Mbps.

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 rates of up to 115.2
Kbps as well as advanced speeds with baud rates of 250 Kbps, 500 Kbps
or 1 Mbps to 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).

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.

The SUPER P3TSSA/P3TSSR/P3TSSE 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.

Chapter 1: Introduction

1-21

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 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 P3TSSA/P3TSSR/P3TSSE User’s Manual

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 Single PentiumTM III FCPGA 500
MHz-1.26+ GHz processors at front bus speeds of 133/100 MHz, and single
FCPGA and FCPGA2 CeleronTM processors at 100/66 MHz front side bus
speeds. 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 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.

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 P3TSSA/
P3TSSR/P3TSSE 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 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. On a 2-pin
jumper, "Closed" means the jumper
is over both pins (to "close" the
connection) and "Open" means the

AGP Pro/4xAGP 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.

2-9 Installing Software Drivers

After all the hardware has been installed you must install the software
drivers. The necessary drivers are all included on the Supermicro CD that
came packaged with your motherboard. After inserting this CD into your
CDROM drive, the display shown in Figure 2-5 should appear. (If this dis­play does not appear, click on the My Computer icon and then on the icon
representing your CDROM drive. Finally, double click on the S "Setup" icon.)

Figure 2-5. Driver/Tool Installation Display Screen

Click the icons showing a hand writing on paper to view the readme files
for each item. Click the tabs to the right of these

in order from top to

bottom

to install each item one at a time. After installing each item, you

must reboot the system before moving on to the next item on the
list. You should install everything here except for the SUPER Doctor utility,

which is optional. The Security and Graphics Drivers support multiple lan­guages. Click the arrows to pull down a menu of choices. The bottom icon
with a CD on it allows you to view the entire contents of the CD.
Note: The memory size reported in the device manager may be less than
expected because some is used by the onboard graphics. Higher screen
resolutions will take up more of this memory.

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 a 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.

3-2

SUPER P3TSSA/P3TSSR/P3TSSE User’s Manual

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

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 Section 1-6 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, 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

Chapter 3: Troubleshooting

1. Please go through the "Troubleshooting Procedures" and "Frequently
Asked Questions" (FAQ) section in this chapter or see the FAQs on our

web site < http://www.supermicro.com/techsupport.htm > before con­tacting Technical Support.

2. BIOS upgrades can be downloaded from our web site at
< http://www.supermicro.com/techsupport/download.htm >.

3-3 Frequently Asked Questions

Question: What are the various types of memory that the P3TSSA/
P3TSSR/P3TSSE motherboard can support?

Answer: The P3TSSA/P3TSSR/P3TSSE 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-

3-4

SUPER P3TSSA/P3TSSR/P3TSSE User’s Manual

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: What's in the CD that came with my 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

3-5

Chapter 3: Troubleshooting

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.

Table 3-1. Shared IRQs

P3TSSA

problems.

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".

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.

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMIBIOS for the P3TSSA/P3TSSR/P3TSSE. The
AMIBIOS program 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:
< http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm >.

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.

information in blocks of rows and columns. RAS stands for Row Ad
dress 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 the 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.

Chapter 4: BIOS

4-29

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®, Windows 95 and Windows NT® are examples of non-ACPI
aware operating systems. Windows 98®, Windows ME, 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 (STR) 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 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."

Standby Time Out

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."

SUPER P3TSSA/P3TSSR/P3TSSE User’s Manual

4-30

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.

Green PC Monitor Power State

This option specifies the power state that a green PC-compliant monitor
enters when BIOS places it in a power saving state after the specified
period of display inactivity has expired. The settings include "Standby",

"Suspend" and "Off."

Video Power Down Mode

This option specifies the power state that the VGA video subsystem enters
after the specified period of display inactivity has expired. The settings
include "Disabled", "Standby" and "Suspend."

Hard Disk Power Down Mode

This option specifies the power conserving state that the hard disk drive(s)
enters after the specified period of inactivity has expired. The settings
include "Disabled", "Standby" and "Suspend."

Hard Disk Time Out (Minutes)

This option specifies the length of hard disk inactivity time that should expire
before entering the power conserving state specified in the previous set­ting. The settings include "Disabled" and increments of "1-15" minutes.

Display Activity

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.)

THRM Throttle Ratio

THRM throttling is used to lower power consumption and reduce heat. The
settings include "87.5%", "75.0%", "62.5%", "50%", "37.5%", "25%" and
"12.5%."

Intruder Sel

This option allows you to set the Intruder SEL setting to "SCI" or "SMI."
"SCI" is an acronym 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 a SCI that notifies
the operating system that the event has occurred. "SMI" is an acronym 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.

Timer Overflow Enable

This allows the system to generate a System Management Interrupt after a
specific amount of time has passed. The settings for this option are "Dis-

abled" and "Enabled."

Thermal SMI Enable

This allows the system to generate a System Management Interrupt after a
specific temperature has been exceeded. The settings for this option are

"Disabled" and "Enabled."

PME SMI Enable

This allows the system to generate a System Management Interrupt after a
Power Management event has ocurred. The settings for this option are

"Disabled" and "Enabled."

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.
