C2SBA+II/C2SBA+/C2SBA/C2SBE User’s Manual

1-2 Chipset Overview

The Intel G33/P35 chipset is specially designed for use with the Intel dual core

processors. It consists of two primary components: the Graphic Memory Controller

Hub (GMCH) and the I/O Controller Hub (ICH9/ICH9R). The GMCH (North Bridge)

manages the data ow between the CPU interface (FSB), the System Memory

interface, the External Graphics interface, and the I/O Controller through the DMI

(Direct Media) Interface. The ICH9/ICH9R (South Bridge) provides a multitude of

I/O related functions.

Graphic Memory Controller Hub (GMCH)

Utilizing a single LGA 775 socket processor, the G33/P35 GMCH supports an FSB

frequency of 1.33 GHz/1.06 GHz. Host-initiated I/O cycles are decoded to the PCI-

Express, the DMI, or the GMCH conguration space. Host-initiated memory cycles

are decoded to PCI-Express, DMI or system memory. The GMCH supports 36-bit

host bus addressing and a Cache Line Size of 64 bytes.

The GMCH supports one or two channels of DDR2 memory with up to two DIMMs

per channel with a maximum bandwidth of 6.4 GB/s in asymmetric mode or 12.8

GB/s in symmetric mode using DDR2 800 MHz memory. It also supports an op-

portunistic refresh scheme, a memory thermal management scheme and Partial

Writes to Memory using Data Mask (DM) signals.

The GMCH contains one PCI-Express x16 (16-lane) port intended for an external

PCI-Express graphics card that is compatible with the PCI Express Base Specica-

tion revision 1.1. This PCI-E x16 port runs at a frequency of 2.5 GB/s on each lane

and supports a maximum theoretical bandwidth of 40 GB/s in each direction for

an aggregate of 8 GB/s @ x16. It supports traditional PCI-/AGP- style trafc and a

PCI-Exp. Enhanced Addressing Mechanism with advanced capabilities in automatic

discovery, negotiation and training of link out of reset.

Providing the high-speed, chip-to-chip connection between the GMCH and ICH9/

ICH9R is the Direct Media Interface (DMI). The DMI integrates advanced priority-

based servicing, allowing for concurrent trafc, true isochronous transfer capabilities

and permitting current as well as legacy software to function seamlessly.

Intel ICH9/ICH9R System Features

The Intel 9th Generation I/O Controller Hub (ICH9/ICH9R) supports a variety of I/O

related functions and PCI devices, including the following:

DMI-to PCI Bridge•

LPC Controller•

Thermal Subsystem•

SMBus Controller•

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 Con-

trol setting in the BIOS chapter of this manual to change this setting. The default

setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the C2SBA+II/C2SBA+/

C2SBA/C2SBE. The motherboard has an onboard System Hardware Monitor chip

that supports PC health monitoring.

Onboard Voltage Monitors for the CPU Core, +1.8V, +3.3V, +3.3V
standby, +5V, Vbat and ±12V

The onboard voltage monitor will scan these 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 dene the sensitivity of the voltage moni-

tor by using SuperO Doctor III.

1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion denes a exible and abstract hardware interface that provides a standard

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 pro-

vides a generic system event mechanism for Plug and Play and an operating- sys-

tem-independent interface for conguration control. ACPI leverages the Plug and

Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with Windows 2000, Windows XP, Windows 2003,

Windows 2003 Servers.

Enhanced Power Management

The onboard ICH9/ICH9R chip provides advanced power management functions

that will greatly improve the performance of various low-power (suspend) states and

1-11

C2SBA+II/C2SBA+/C2SBA/C2SBE User’s Manual

enhance clock control. A hardware-based component provides software-indepen-

dent thermal management that is compatible with the ACPI Revision 3.0a.

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 will function like a normal

keyboard during system boot-up.

Wake-On-LAN (WOL)

Wake-On-LAN is dened as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and asset

tracking can occur after hours and on weekends so that daily LAN trafc is kept

to a minimum and users are not interrupted. The motherboard has a 3-pin header

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires 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 1 GHz and faster.

The C2SBA+II/C2SBA+/C2SBA/C2SBE accommodates 12V ATX power

supplies. Although most power supplies generally meet the specications required

by the CPU, some are inadequate. A 2-Amp of current supply on a 5V Standby

rail is strongly recommended.

It is strongly recommended that you use a high quality power supply that meets

12V ATX power supply Specication 1.1 or above. It is also required that the 12V

4-pin power connection (J41) be used for high-load congurations. In areas where

noisy power transmission is present, you may choose to install a line lter 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

1-7 Versatile Media Capabilities

HighDenitionAudio

The High Denition Audio Controller embedded in the ICH9/ICH9R delivers up to

4 codecs that can be used for different types of codecs, such as audio and mo-

dem codecs. Operating at 3.3V or 1.5V, the embedded Audio Controller supports

a multi-channel audio stream, 32-bit sample depth, up to 192 kHz of same rate,

and can be used with a variety of microphones for input. With these versatile audio

capabilities built in, the C2SBA+II/C2SBA+/C2SBA/C2SBE provides the user with

a surreal audio experience that is larger than life.

I/O Virtualization Technology (VT-d)

With the Intel ICH9 built in, the C2SBA+II/C2SBA+/C2SBA/C2SBE supports I/O

Virtualization Technology (VT-d) that enables multiple operating systems and ap-

plications to run in independent partitions. Each partition uses its own subset of host

physical memory, and behaves like a virtual machine (VM), providing isolation and

protection across multiple partitions. This feature is available when a processor that

supports the virtualization of platforms is installed on the motherboard.

1-8 Super I/O

The disk drive adapter functions of the Super I/O chip include a oppy 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 genera-

tor, 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 oppy disk drives. The Super I/O supports two 360 K,

720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,

500 Kb/s or 1 Mb/s.

It also provides two high-speed, 16550 compatible serial communication ports

(UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable baud

rate generator, complete modem control capability and a processor interrupt sys-

tem. 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 provides functions that comply with the ACPI (Advanced Congura-

tion and Power Interface), which includes support of legacy and ACPI power man-

agement through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.

2-1 Static-Sensitive Devices

Electro-Static-Discharge (ESD) can damage electronic com ponents. To prevent

damage to your system board, it is important to handle it very carefully. The following

measures are generally sufcient 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.

• Use only the correct type of onboard CMOS battery as specied by the manu-

facturer. Do not install the onboard battery upside down to avoid possible explo-

sion.

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 Motherboard Installation

Note: Be sure to mount the motherboard into the chassis before you install the

CPU onto the motherboard.

All motherboards have standard mounting holes to t different types of chassis.

Make sure that the locations of all the mounting holes for both motherboard and

chassis match. Make sure that the metal standoffs click in or are screwed in tightly.

Then use a screwdriver to secure the motherboard onto the motherboard tray.

(Caution: 1. Please do not use a force greater than 8 lb/inch on each mounting

screw during motherboard installation. 2. Some components are very close to the

mounting holes. Please take precautionary measures to prevent damage to these

components when installing the motherboard to the chassis.)

2-3 Processor and Heatsink Fan Installation

When handling the processor package, avoid placing

direct pressure on the label area of the fan.

Notes: 1. Always connect the power cord last and always remove it before adding,

removing or changing any hardware components. Make sure that you install the

processor into the CPU LGA 775 socket before you install the CPU heatsink.

2. The Intel LGA 775 Processor package contains the CPU fan and heatsink as-

sembly. If you buy a CPU separately, make sure that you use only Intel-certied

multi-directional heatsink and fan.

3. Make sure to install the motherboard into the chassis before you install the CPU

heatsink and fan.

4. When purchasing an LGA 775 Processor or when receiving a motherboard with

an LGA 775 Processor pre-installed, make sure that the CPU plastic cap is in place

and none of the CPU pins are bent; otherwise, contact the retailer immediately.

Installation of the Heatsink

1. Locate the CPU Fan on the mother-

board. (Refer to the layout on the right

for the CPU Fan location.)

2. Position the heatsink in such a way

that the heatsink fan wires are closest

to the CPU fan and are not interfered

with other components.

3. Inspect the CPU Fan wires to make

sure that the wires are routed through

the bottom of the heatsink.

4. Remove the thin layer of the protec-

tive lm from the copper core of the

heatsink.

(Warning: CPU overheat may occur if

the protective lm is not removed from

C2SBA+II/C2SBA+/C2SBA/C2SBE User's Manual

2-4 Installing DIMMs

Note: Check the Super Micro web site for recommended memory modules.

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also note that the

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

DIMM Installation

1. Insert the desired number of DIMMs into the memory slots, starting with DIMM1A.

The memory scheme is interleaved so you must install two modules at a time,

beginning with DIMM1A, DIMM1B, then, DIMM2A and DIMM2B

2. Insert each DIMM module vertically into its slot. Pay attention to the notch along

the bottom of the module to prevent inserting the DIMM module incorrectly.

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

Repeat for all modules (See step 1 above).

Memory Support

The C2SBA+II/C2SBA+/C2SBA/C2SBE supports up to 8 GB Unbuffered Non-

ECC DDR2 800/677 MHz in 4 DIMMs. Populating DIMM#1A,DIMM#1B, and/or

DIMM#2A, DIMM#2B with memory modules of the same size and of the same

type will result in dual channel, two-way interleaved memory which is faster than

the single channel, non-interleaved memory.

Notes:

1. Due to the OS limitations, some operating systems may not show more than 4

GB of memory.

2. Both Unbuffered ECC and Non-ECC memory modules can be installed in the

memory slots. However, the functionality of ECC is not supported by the

chipset.

3. Due to memory allocation to system devices, memory remaining available for

operational use will be reduced when 4 GB of RAM is used. The reduction

in memory availability is disproportional. (Refer to the following Memory

Availability Table for details.) For Microsoft Windows users: Microsoft imple-

mented a design change in Windows XP with Service Pack 2 (SP2) and

Windows Vista. This change is specic to the Physical Address Extension

(PAE) mode behavior which improves driver compatibility. For more informa-

tion, please read the following article at Microsoft’s Knowledge Base website

The C2SBA+II/ C2SBA+/C2 SBA/C2SBE

has ve chassis fan headers (Fan 1 to Fan

5). Fan 1 is the CPU Fan. Fan 2 to Fan

5 are system/chassis fans. (Note: Pins

1-3 of a 4-pin fan headers are backward

compatible with the traditional 3-pin fans.)

See the table on the right for pin denitions.

The onboard fan speeds are controlled by

Thermal Management via BIOS Hardware
Monitoring in the Advanced Setting. (Note:

Default: Disabled. When using Thermal

Management settings, please use all 3-pin

fans or all 4-pin fans on the motherboard.)

VGA Connector

(Not available on the C2SBE)

A VGA connector (JG1) is located next to the

USB ports on the IO backplane. Refer to the

board layout below for the location.

Front Panel Audio Control

When front panel headphones are plugged

in, the back panel audio output is disabled.

This is done through the FP Audio header

(J12). If the front panel interface card is not

connected to the front panel audio header,

jumpers should be installed on the header

(J12) pin pairs: 1-2, 5-6, and 9-10. If these

jumpers are not installed, the back panel

line out connector will be disabled and

microphone input Pin 1 will be left oating,

which can lead to excessive back panel

microphone noise and cross talk. See the

table below for pin denitions.

Power LED

The Power LED connector is designated

JLED. This connection is used to provide

Explanation of
Jumpers

To m o d i f y t h e o p e r a t i o n 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 identied with a

square solder pad on the printed circuit

board. See the motherboard layout

pages for jumper locations.

Note: On two pin jumpers, "Closed"

means the jumper is on and "Open"

means the jumper is off the pins.

GLAN Enable/Disable

JPL1 enables or disables the GLAN

Port on the motherboard. See the

table on the right for jumper settings.

The default setting is enabled.

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads

to prevent the accidental clearing of CMOS. To clear CMOS, use a metal object such

as a small screwdriver to touch both pads at the same time to short the connection.

Always remove the AC power cord from the system before clearing CMOS.

Note: For an ATX power supply, you must completely shut down the system, remove

the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog is a system monitor that can reboot

the system when a software application hangs.

Close pins 1-2 to reset the system if an applica-

tion hangs. Close pins 2-3 to generate a non-

maskable interrupt signal for the application that

hangs. See the table on the right for jumper set-

tings. Watch Dog must also be enabled in the

BIOS. (Note: When enabled, the user needs to

write his/her own application software to disable

the Watch Dog Timer.)

USB Wake-Up

Use JPUSB jumpers (JPUSB1/JPUSB2) to en-

able the function of "System Wake-Up via USB

devices", which allows you to "wake-up" the

system by pressing a key on the USB keyboard

or by clicking the USB mouse of your system.

The JPUSB jumpers are used together with the

USB Wake-Up function in the BIOS. Enable

both jumpers and the BIOS setting to allow the

system to "wake-up via USB Devices". See the

table on the right for jumper settings and jumper

connections. (Note: JPUSB1 is for Back Panel

USB ports:1/2/3/4/5/6, and JPUSB2 is for Front

Panel USB ports:7/8/9/10 and Front Accessible

USB ports: 11/12.)

(Note: The default jumper setting for the USB

ports is "Disabled". However, when the "USB

Wake-Up" function is enabled in the BIOS and

the desired USB ports are enabled via the

JPUSB jumper, please be sure to remove all

USB devices from the USB ports whose USB

jumpers are set to "Disabled" before the system

goes into the standby mode.)

Troubleshooting

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.

Always disconnect the AC power cord before adding, changing or installing any

hardware components.

Before Power On

1. Make sure that there are no short circuits between the motherboard and chas-

sis.

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 and heatsink (making sure it is fully seated) and connect the

chassis speaker and the power LED to the motherboard. Check all jumper

settings as well.

5. Use the correct type of onboard CMOS battery as specied by the Manufacturer.

Do not install the CMOS battery upside down to avoid possible explosion.

6. Make sure that the 4-pin 12v power connector at J41 is connected to your

power supply.

No Power

1. Make sure that there are no short circuits between the motherboard and chas-

sis.

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 sup-

plies ~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.

3-1

C2SBA+II/C2SBA+/C2SBA/C2SBE User's Manual

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 that the DIMM modules are properly and fully installed.

2. You should be using unbuffered DDR2 memor y (see the next page). Also, it

is recommended that you use the same memory speed for all DIMMs in the

system. See Section 2-4 for memory limitations.

3. Check for bad DIMM modules or slots by swapping modules between slots and

noting the results.

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

LosingtheSystem’sSetupConguration

1. Make sure 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 sup-

plies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not x the Setup Conguration problem, contact your

vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note

that as a motherboard manufacturer, Super Micro does not sell directly to end-us-

ers, so it is best to rst check with your distributor or reseller for troubleshooting

services. They should know of any possible problem(s) with the specic system

conguration 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

(http://www.supermicro.com/support/faqs/) befo re contacting Technica l

Suppor t.

2. BIOS upgrades can be downloaded from our web site at (http://www.supermicro

com/support/bios/).

Note: Not all BIOS can be ashed; it depends on the modications to the

boot block code.

3. If you still cannot resolve the problem, include the following information when

3-2

Chapter 3: Troubleshooting

contacting Super Micro for technical support:

• Motherboard model and PCB revision number

• BIOS release date/version (this can be seen on the initial display when your

system rst boots up)

• System conguration

An example of a Technical Support form is on our web site at (http://www.

supermicro.com/support/contact.cfm).

4. Distributors: For immediate assistance, please have your account number ready

when placing a call to our technical suppor t depar tment. We can be reached

by e-mail at [e-mail], by phone at:[phone], option

2, or by fax at (408)503 -8019.

3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: T he C2SBA+II/C2SBA+/C2SBA/C2SBE supports unbuffered, DDR2

667/800 MHz memory modules. See Section 2-4 for details on installing

memory.

Question: Why does Microsoft Windows XP (SP2) and Windows Vista show

less memory than what is physically installed?

Answer: Microsoft implemented a design change in Windows XP with Service

Pack 2 (SP2) and Windows Vista. This change is specic to the Physical Ad-

dress Extension (PAE) mode behavior which improves driver compatibility. For

more information, please read the following article at Microsoft’s Knowledge

Base website at: http://support.microsoft.com/kb/888137.

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are not

experiencing any problems with your system. Updated BIOS les are located

on our web site at http://www.supermicro.com/support/bios/. Please check our

BIOS warning message and the information on how to update your BIOS on our

web site. Select your motherboard model and download the BIOS (.rom) le to

your computer. Also, check the current BIOS revision and make sure that it is

newer than your BIOS before downloading. You may choose the zip le or the

.exe le. If you choose the zipped BIOS le, please unzip the BIOS le onto a

bootable device or a USB pen/thumb drive. To ash the BIOS, run the batch

le named "ash.bat" with the new BIOS .rom le from your bootable device or

USB pen/thumb drive. Use the following format:

F:\> ash xxxxxxxx.rom <Enter>

Note: Be sure to insert a space immediately after "ash" and use only the le

named “ash.bat” to update the BIOS.

3-3

Chipset section of the BIOS setup.

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: After I have installed 4 pieces of 1GB Memory, why does the BIOS

only detect about 3.145 GB of memory during POST?

Answer: Because the chipset does not support memory remapping, and PCI-E

memory requires a great deal of memory, so there is a memory hole located

around the 4GB memory address.

Question: How do I connect the ATA100/66 cable to my IDE device(s)?

Answer: The 80-wire/40-pin high-density ATA100/66 IDE cable that came

with your system has two connectors to support t wo drives. This special cable

must be used to take advantage of the speed the ATA100/66 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.

Question: Why doesn' t by USB devices no longer work correctly after

installing the Intel Chipset Software Installation Utility in Windows XP or

Windows Server 2003?

Answer: This is a timing conict between Windows File Protection and the

Setup program. This is described in greater detail, and a hotx is available at

Microsoft's website at http://support.microsoft.com/kb/921411/en-us

Chapter 4
BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the C2SBA+II/

C2SBA+/C2SBA/C2SBE. The Phoenix ROM BIOS is stored in a ash chip and

can be easily upgraded using a oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been added

or deleted and might not yet be recorded in this manual. Please refer to the Manual

Download area of the Super Micro web site <http://www.supermicro.com> for any

changes to the BIOS not reected 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 Phoenix BIOS stores the system parameters,

types of disk drives, video displays, etc. in the CMOS. The CMOS memory re-

quires very little electrical power. When the computer is turned off, a backup battery

provides power to the CMOS logic, enabling it to retain system parameters. Each

time the computer is powered on, the computer is congured with the values stored

in the CMOS logic by the system BIOS, which gains control at boot-up.

HowToChangetheCongurationData

The CMOS information that determines the system parameters may be changed

by entering the BIOS Setup utility. This Setup utility can be accessed by pressing

the <Delete> key at the appropriate time during system boot. (See below.)

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 Security and Power menus. Beginning with Section 4 -3,

detailed descriptions are given for each parameter setting in the Setup utility.

Warning: Do not shut down or reset the system while updating the BIOS

to prevent possible boot failure.

Hardware Monitoring

CPU Overheat Alarm

This option allows the user to select the CPU Overheat Alarm setting which de-

termines when the CPU OH alarm will be activated to provide warning of possible

CPU overheat.

Warning: Any temperature that exceeds the CPU threshold temperature predened

by the CPU manufacturer may result in CPU overheat or system instability. When

the CPU temperature reaches this predened threshold, the CPU and system cool-

ing fans will run at full speed.

The options are:

The Default Alarm Setting: Select this setting if you want the CPU overheat alarm

(including the LED and the buzzer) to be triggered when the CPU temperature

reaches about 5oC above the threshold temperature as predened by the CPU

manufacturer to give the CPU and system fans additional time needed for CPU

and system cooling.

The Early Alarm Setting: Select this setting if you want the CPU overheat alarm

(including the LED and the buzzer) to be triggered as soon as the CPU temperature

reaches the CPU overheat threshold as predened by the CPU manufacturer.

CPU1 Temperature

The CPU Temperature feature will display the CPU temperature status as detected

by the BIOS:

4-19

C2SBA+II/C2SBA+/C2SBA/C2SBE User's Manual

Low – This level is considered as the ‘normal’ operating state. The CPU temperature

is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will

run normally as congured in the BIOS (Fan Speed Control).

User intervention: No action required.

Medium – The processor is running warmer. This is a ‘precautionary’ level and

generally means that there may be factors contributing to this condition, but the CPU

is still within its normal operating state and below the CPU ‘Temperature Tolerance’.

The motherboard fans and CPU will run normally as congured in the BIOS. The

fans may adjust to a faster speed depending on the Fan Speed Control settings.

User intervention: No action is required. However, consider checking the CPU

fans and the chassis ventilation for blockage.

High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem-

perature Tolerance’ has been reached (or has been exceeded) and may activate

an overheat alarm:

The Default Alarm – the Overheat LED and system buzzer will activate if the High

condition continues for some time after it is reached. The CPU fan will run at full

speed to bring the CPU temperature down. If the CPU temperature still increases

even with the CPU fan running at full speed, the system buzzer will activate and

the Overheat LED will turn on.

The Early Alarm – the Overheat LED and system buzzer will be activated exactly

when the High level is reached. The CPU fan will run at full speed to bring the

CPU temperature down.

Note: In both the alarms above, please take immediate action as shown below.

See CPU Overheat Alarm to modify the above alarm settings.

User intervention: If the system buzzer and Overheat LED has activated, take

action immediately by checking the system fans, chassis ventilation and room

temperature to correct any problems. Note: the system may shut down if it con-

tinues for a long period to prevent damage to the CPU.

Notes: The CPU thermal technology that reports absolute temperatures

(Celsius/Fahrenheit) has been upgraded to a more advanced feature by

Intel in its newer processors. The basic concept is each CPU is embedded

by unique temperature information that the motherboard can read. This

‘Temperature Threshold’ or ‘Temperature Tolerance’ has been assigned

at the factory and is the baseline on which the motherboard takes action

during different CPU temperature conditions (i.e., by increasing CPU Fan

speed, triggering the Overheat Alarm, etc). Since CPUs can have different

‘Temperature Tolerances’, the installed CPU can now send information to

the motherboard what its ‘Temperature Tolerance’ is, and not the other way

around. This results in better CPU thermal management.

4-20

Chapter 4: BIOS

Supermicro has leveraged this feature by assigning a temperature status to certain

thermal conditions in the processor (Low, Medium and High). This makes it easier

for the user to understand the CPU’s temperature status, rather than by just simply

seeing a temperature reading (i.e., 25oC).

The information provided above is for your reference only. For more information on

thermal management, please refer to Intel’s Web site at www.Intel.com.

System Temperature

This displays the system's absolute temperature reading (i.e., 27oC)

Fan1 - Fan 5

If the feature of Auto Fan Control is enabled, the BIOS will automatically display

the status of the fan as specied.

Fan Speed Control Modes

This feature allows the user to decide how the system controls the speeds of the

onboard fans. The CPU temperature and the fan speed are correlative. When

the CPU on-die temperature increases, the fan speed will also increase, and vice

versa. If the option is set to “4-pin”, the fan speed will be controlled by Pulse Width

Modulation (PWM). Select “Workstation” if your system is used as a Workstation.

Select “Disable” to disable the fan speed control function to allow the onboard

fans to constantly run at full speed (12V). The Options are: 1. Disable and 2.

Optimized for Workstations with 4-pin.

Note: In the Windows OS environment, the Supero Doctor III settings take prece-

dence over the BIOS settings. When rst installed, Supero Doctor III adopts the

temperature threshold settings previously set in the BIOS. Any subsequent changes

to these thresholds must be made within Supero Doctor, since the SD III settings

override the BIOS settings. For the Windows OS to adopt the BIOS temperature

threshold settings, please change the SDIII settings to be the same as those set

in the BIOS.

Appendix B

BIOS POST Codes

This section lists the POST (Power On Self Test) codes for the Phoenix BIOS. POST

codes are divided into two categories: recoverable and terminal.

Recoverable POST Errors

When a recoverable type of error occurs during POST, the BIOS will display an

POST code that describes the problem. BIOS may also issue one of the follow-

ing beep codes:

1 long and two short beeps - video conguration error

1 repetitive long beep - no memory detected

1 continuous beep w/ Front Panel Overheat LED on - system overheat

Terminal POST Errors

If a terminal type of error occurs, BIOS will shut down the system. Before doing

so, BIOS will write the error to port 80h, attempt to initialize video and write the

error in the top left corner of the screen. The following is a list of codes that may

be written to port 80h.

If the BIOS detects errors on 2C, 2E, or 30 (base 512K RAM error), it displays an

additional word-bitmap (xxxx) indicating the address line or bits that have failed. For

example, “2C 0002” means address line 1 (bit one set) has failed. “2E 1020" means

data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also

sends the bitmap to the port-80 LED display. It rst displays the checkpoint code,

followed by a delay, the high-order byte, another delay, and then the low-order byte

of the error. It repeats this sequence continuously.

Appendix C
Intel HostRAID Setup Guidelines

(For the C2SBA+II Only)

After all the hardware has been installed, you must rst congure SATA HostRAID

or SAS HostRAID before you install the Windows Operating System and other

software drivers.

Important Notes to the User:

Note 1: This chapter describes RAID Conguration Instructions for the Intel ICH9R

Host RAID Controller designed for the Windows OS.

Note 2: If you do not wish to congure onboard SATA or SAS RAID functions,
please go directly to Section C-2 and Appendix D for the operating system & other

software installation instructions.

C-1 Introduction to Serial ATA and Parallel ATA

To congure the SATA RAID functions, you must rst use the Intel ICH9R SATA

RAID Utility program to congure the RAID Level that you desire before installing

the Windows XP/2003 operating system and other software drivers. (The necessary

drivers are all included on the Super Micro CD that came packaged with your

motherboard.) Note: the current version of the ICH9R SATA RAID Utility can only

support Windows XP/2003 Operating Systems.

Serial ATA (SATA)

Serial ATA (SATA) is a physical storage interface that uses a single cable with a

minimum of four wires to create a point-to-point connection between devices. It

is a serial link, which supports transfer rates up to 3.0 Gbps. Because the serial

cables used in SATA are thinner than the traditional cables used in Parallel ATA

(PATA), SATA systems have better airow and can be installed in smaller chassis.

In addition, the cables used in PATA are limited to a length of 40cm, while Serial

ATA cables can be up to one meter in length. Overall, SATA provides better func-

tionality than PATA.

Introduction to the Intel ICH9R Serial RAID

Located in the South Bridge of the G33 chipset, the I/O Controller Hub (ICH9R)

provides the I/O subsystem with access to the rest of the system. It supports 1-

channel UltraATA/100 Bus Master IDE controller (PATA) and six Serial ATA (SATA)

ports. The ICH9R supports the following PATA and SATA device congurations:

Legacy mode and Native mode.

IntelHostRAIDCongurations

The following types of Intel's HostRAID congurations are supported:

RAID 0 (Data Striping): this writes data in parallel, interleaved ("striped") sections

of two hard drives. Data transfer rate is doubled over using a single disk.

RAID1 (Data Mirroring): an identical data image from one drive is copied to another

drive. The second drive must be the same size or larger than the rst drive.

RAID 10 (Striping & Mirroring): RAID 0 and 1 schemes are combined (without parity

information) to get the benets of both.

RAID 5: both data and parity information are striped and mirrored across three or

more hard drives.

Intel Matrix Storage

The Intel Matrix Storage, supported by the ICH9R, allows the user to create RAID

0, RAID 1, RAID 10 and RAID 5 sets by using only six identical hard disk drives.

The Intel Matrix Storage Technology creates two partitions on each hard disk drive

and generate a virtual RAID 0, RAID 1, RAID 10 and RAID 5 sets. It also allows

you the change the HDD partition size without any data.
