Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard

CPU and chassis fans are controlled by Thermal Management 2 (TM2) via BIOS

(under Hardware Monitoring in the Advanced Setting).

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-defi ned

threshold. The overheat circuitry runs independently from the CPU. Once it detects

that the CPU temperature is too high, it will automatically turn on the thermal fan

control to prevent any overheat damage to the CPU. The onboard chassis thermal

circuitry can monitor the overall system temperature and alert users when the chas-

sis temperature is too high.

X7DBT/X7DBT-INF/X7DGT/X7DGT-INF User's Manual

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It continues to operate when

the system enters Standby 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 defi ne an overheat temperature. When the

temperature exceeds a user pre-defi ned threshold, both overheat fan and warning

LED are triggered.

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, if the system is running

low on virtual memory and there is insuffi cient hard drive space for saving the

data, you can be alerted of the potential problem. You can also confi gure Supero

Doctor to provide you with warnings when the system temperature goes beyond

a pre-defi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -

cation defi nes a fl exible 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 confi guration control. ACPI leverages the Plug

and Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with both Windows 2000 and Windows NT 5.0.

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.

1-12

Chapter 1: Introduction

Main Switch Override Mechanism

When a power supply is used, the power button can function as a system suspend

button to make the system enter a SoftOff state. The monitor will be suspended

and the hard drive will spin down. Pressing the power button again will cause the

whole system to wake up. During the SoftOff state, the power supply provides

power to keep the required circuitry in the system alive. In case the system mal-

functions and you want to turn off the power, just press and hold the power button

for 4 seconds. This option can be set in the Boot Features Section under Advanced

Setup in the BIOS.

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 defi ned 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 traffi 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.

1-6 Power Supply

Supermicro's proprietary power connectors are used in the X7DBT/X7DBT-INF/

X7DGT/X7DGT-INF. Please refer to Section 2-5 Connecting Cables on Page 2-14

for more information.

2-1 Static-Sensitive Devices

Electric-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 suffi 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 specifi 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 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 socket before you install the CPU heatsink.

2. Intel's boxed Xeon CPU package contains the CPU fan and heatsink assembly.

If you buy a CPU separately, make sure that you use only Intel-certifi ed multi-di-

rectional 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 771 CPU or when receiving a motherboard with an LGA

771 CPU 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.

5. Refer to the MB Features Section for more details on CPU support.

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fi t different types of chas-

sis. 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. (*Note: some components are very close to the mounting holes. Please take

precautionary measures to prevent damage done to these components when you

install the motherboard to the chassis.)

X7DBT/X7DBT-INF/X7DGT/X7DGT-INF User's Manual

2-3 Installing DIMMs

Note: Check the Supermicro 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 (See Figure 2-2)

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

#1A. The memory scheme is interleaved so you must install two modules

at a time, beginning with DIMM #1A, then DIMM #2A and so on. For optimal

performance, please install four modules of the same type and same speed

in Branch 0 and Branch 1 at a time (up to 8 modules maximum). (*See the

Memory Installation Table Below.)

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 X7DBT/X7DBT-INF/X7DGT/X7DGT-INF supports up to 32 GB fully buffered

(FBD) ECC DDR2 533/667 in 8 DIMMs. Populating DIMM modules with pairs

of memory modules of the same size and same type will result in Interleaved

Memory which will increase memory performance.

*Note 1: Due to OS limitations, some operating systems may not show more than

4 GB of memory.

(*Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM
slot not to be populated. ii. Both FBD 533 MHz and 667MHz DIMMs are
supported; however, you need to use the memory modules of the same
speed and of the same type on a motherboard. iii. Interleaved memory is
supported when pairs of DIMM modules are installed. To optimize memory
performance, please populate pairs of memory modules in both Branch 0
and Branch 1. iv. For memory to work properly, you need to follow the
restrictions listed above. )

ATX Power 20-pin Connector

20-pin Proprietary Power
Connectors

There are two 20-pin main power

supply connectors (J17, JP10) and a

4-pin auxiliary power connector on the

motherboard. These power connectors

meet the SSI EPS 12V specifi cation.

*For power supply to work properly,

please refer to the notes below. See

the table on the right for pin defi nitions.

Also refer to the layout below for the

PWR connector locations.

Note 1: You cannot use both 20-pin power connectors located at J17 (the right

side connector) and JP10 (the left side connector) as input power supply connec-

tors at the same time. Only one connector can be used for input power supply to

the motherboard at a time. *For proper use of these proprietary PWR Connectors,

please customize your PWR cables based on the SMC PWR Connector Pin-Out

Defi nitions listed above.

Explanation of
Jumpers

To modify the operation of the

motherboard, jumpers can be used

to choose between optional settings.

Jumpers create shorts between two

pins to change the function of the

connector. Pin 1 is identifi 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"

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: You must completely shut down the system, remove the AC power

cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

JWD controls the Watch Dog function. Watch

Dog is a system monitor that can reboot the sys-

tem when a software application hangs. Close

pins 1-2 to reset the system if an application

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

able 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.

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.

Note: Always disconnect the 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 one CPU at a time (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 only the correct type of CMOS onboard battery as recommended by the

Manufacturer. Do not install the onboard battery upside down to avoid pos-

sible explosion.

No Power

1. Make sure that there are no short circuits 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 and

Appendix B for details on beep codes.

Losing the System’s Setup Confi 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

3-1

X7DBT/X7DBT-INF/X7DGT/X7DGT-INF User's Manual

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 fi x the Setup Confi guration problem, contact your

vendor for repairs.

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. Determine if different speeds of DIMMs have been installed and verify that the

BIOS setup is confi gured for the fastest speed of RAM used. It is recom-

mended to use the same RAM speed for all DIMMs in the system.

3. Make sure you are using the correct type of DDR2 Fully Buffered (FBD) ECC

533/667 SDRAM (*recommended by the manufacturer.)

4. Check for bad DIMM modules or slots by swapping a single module between

four slots and noting the results.

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

memory scheme is used, you must install two modules at a time, beginning

with Bank 1, then Bank 2, and so on (see Section 2-3).

6. Check the position of the 115V/230V switch on the power supply.

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 fi rst check with your distributor or reseller for troubleshooting

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

confi guration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked Ques-

tion' (FAQ) sections in this chapter or see the FAQs on our web site (http://

www.supermicro.com/support/faqs/) before contacting Technical Support.

Chapter 4

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DBT/X7DBT-INF/

X7DGT/X7DGT-INF. The Phoenix ROM BIOS is stored in a fl ash chip and can be easily

upgraded using a fl 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 Supermicro web site <http://www.supermicro.com> for any

changes to the BIOS that may not be refl 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 requires

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

vides power to the CMOS Logic, enabling it to retain system parameters. Each time

the computer is powered on the computer is confi gured with the values stored in

the CMOS Logic by the system BIOS, which gains control at boot up.

How To Change the Confi 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 de-

scriptions are given for each parameter setting in the Setup utility.

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

to prevent possible boot failure.

Appendix B

BIOS POST Codes

This section lists the POST (Power On Self Test) codes for the PhoenixBIOS. 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 confi guration error

1 repetitive long beep - no memory detected

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 fi rst displays the checkpoint code,

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

the error. It repeats this sequence continuously.

Appendix C

Intel HostRAID Setup Guidelines

After all the hardware has been installed, you must fi rst confi gure Intel's ESB2

SATA RAID* before you install the Windows Operating System and other software

drivers.

Important Notes to the User:

*Note 1: If you do not wish to confi gure onboard SATA RAID functions, please go
directly to Section C-3, Appendix D and Appendix E for OS and other software

installation instructions.

*Note 2: This chapter describes RAID Confi guration Instructions for the Intel ESB2

RAID Controller designed for the Windows OS.

C-1 Introduction to Serial ATA and Parallel ATA

To confi gure the SATA RAID functions, you must fi rst use the Intel ESB2 SATA

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

the Windows XP/2000/2003 operating system and other software drivers. (The

necessary drivers are all included on the Supermicro CD that came packaged with

your motherboard.) Note that the current version of the ESB2 SATA RAID Utility

can only support Windows XP/2000/2003 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 airfl ow and can be installed in smaller chassis than

Parallel ATA. In addition, the cables used in PATA are li m ited to a lengt h of 40cm ,

while Serial ATA cables can be up to one meter in length. Overall, SATA provides

better functionality than PATA.

Introduction to the Intel ESB2 Serial RAID

Located in the South Bridge of the 5000P/5000X chipset, the I/O Controller Hub

(ESB2) provides the I/O subsystem with access to the rest of the system. It supports

an 1-channel UltraATA/100 Bus Master IDE controller (PATA) and six Serial ATA

(SATA) ports. The ESB2 supports the following PATA and SATA device confi gura-

tions: Legacy mode and Native mode.

C-1

X7DBT/X7DBT-INF/X7DGT/X7DGT-INF User's Manual

The Intel HostRAID Confi gurations

The following types of Intel's HostRAID confi 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 fi rst drive.

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

information) to get the benefi ts of both.

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

more hard drives.

The Intel Matrix Storage

The Intel Matrix Storage, supported by the ESB2, 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.
