Introduction

1-1 Overview

The SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM supports Pentium II 233-333 MHz and Celeron 266-433 MHz processors at a 66 MHz bus speed, Pentium II 350-450 MHz and Pentium III processors at a 100 MHz FSB speed. The SUPER P6DBU/P6DBS/P6DBE supports dual Pentium II and III processors, while the SUPER P6SBU/P6SBS/P6SBA/P6SBM supports a single Pentium II or III processor*. All seven motherboards are based on Intel’s 440BX chipset, which supports a 66/100 MHz front side bus speed, an Accelerated Graphics Port (AGP), Wake-on-LANÔ , SDRAM, concurrent PCI and a 33 MB/s Ultra DMA burst data transfer rate. (See notes below.)

While all of the motherboards are the ATX form factor, the P6DBU and P6DBE have 5 PCI and 2 ISA slots with one shared. The SUPER P6DBS, P6SBU, P6SBS and P6SBA have 4 PCI and 3 ISA slots with one shared, and the SUPER P6SBM has 3 PCI and 1 ISA slots with one shared. All seven motherboards have the AGP port and all but the P6SBM can support up to 1 GB EDO at 66 MHz or 512 MB unbuffered SDRAM or maximum of 1 GB registered SDRAM memory in 4 168-pin DIMM sockets. The SUPER P6SBM can accommodate 768 MB registered or 384 MB unbuffered SDRAM. All these motherboards support both ECC and non-ECC type memory.

AGP reduces contention between the CPU and I/O devices by broadening the graphics bandwidth to memory. It delivers a maximum of 532 MB/s in the 2xAGP transfer mode, which is quadruple the PCI speed!

Wake-On-LAN allows for remote network management and configuration of the PC, even in off-hours when the PC is turned off. This reduces the complexity of managing the network.

Another feature that maximizes customer satisfaction and simplicity in managing the computer is support for the PC 98 and the Advanced Configuration and Power Interface (ACPI) standards. With PC Health Monitoring, you can protect your system from problems before they even occur.

*Notes: 1. Celeron is single processor only.

2. Currently, the P6DBE/P6DBU/P6SBU/P6SBA motherboard supports CPU speeds up to 1GHz with 100 MHz FSB.

Included I/O on all motherboards are 2 EIDE ports, a floppy port, an ECP/EPP supported parallel port, PS/2 mouse and PS/2 keyboard ports, 2 serial ports, an infrared port and 2 USB ports. The SUPER P6DBU and P6SBU provide an onboard Adaptec 7890 Ultra II SCSI controller with data transfer rates of up to 80 MB/s and an optional RAIDport III (ARO-1130U2). The SUPER P6DBS and P6SBS have an integrated onboard Adaptec 7895 MultiChannel UW SCSI controller. The dual channels enable a data transfer rate of 40 MB/s per channel. In addition, these two motherboards have an onboard RAID port to support the Adaptec ARO-1130SA/CA RAIDport II card for increased I/O performance and fault tolerance.

1-2 Chipset Overview

The 440BX chipset, developed by Intel, is the ultimate processor platform targeted for 3D graphics and multimedia applications. Along with a Systemto-PCI bridge integrated with an optimized DRAM controller and data path, this chipset supports the Accelerated Graphics Port (AGP) interface. AGP is a high performance, component level interconnect targeted at 3D applications and based on a set of performance enhancements to PCI. The I/O subsystem portion of the 440BX platform is based on the PIIX4E, a highly integrated version of Intel's PCI-to-ISA bridge family.

The PCI/AGP and system bus interface controller (82443BX) supports up to two Pentium II/III processors. It provides an optimized 72-bit DRAM interface (64-bit data plus ECC) that supports 3.3V DRAM technology. The controller provides the interface to a PCI bus operating at 33 MHz. This interface implementation is compliant with the PCI Rev 2.1 Specification. The AGP interface is based on AGP Specification Rev 1.0. It can support data trans-

fer rates of up to 133 MHz (532 MB/s).

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER P6DBU/P6DBS/P6DBE/P6SBU/P6SBS/P6SBA/P6SBM. All have an onboard System Hardware Monitor chip that supports PC health monitoring.

Seven Onboard Voltage Monitors for the CPU Core(s), CPU I/O, +3.3V,

±±

±5V,

and

±±

±12V

The onboard voltage monitor will scan these seven monitored 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.

1-22

Three-Fan Status Monitors with Firmware/Software On/Off Control

The PC health monitor can check the RPM status of the cooling fans. The onboard 3-pin CPU fan is controlled by the ACPI BIOS and the ACPI-enabled operating system. The thermal fans are controlled by the overheat detection logic.

Environment Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn on a back-up fan whenever the CPU temperature exceeds a userdefined threshold. The overheat circuitry runs independently from the CPU. It can continue to monitor for overheat conditions even when the CPU is in sleep mode. Once it detects that the CPU temperature is too high, it will automatically turn on the back-up 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. For power saving purposes, the user has the option to shut down the CPU fan.

CPU Overheat Alarm, LED and Control in P6DBS/P6DBE/ P6DBU/P6SBU/P6SBS/P6SBM

This feature is available when the user enables the CPU overheat warning function in the BIOS (see page 5-18). The overheat alarm will activate when the CPU temperature exceeds the temperature configured by the user. When the overheat alarm is activated, both the overheat fan and the warning LED are triggered.

Chassis Intrusion Detection

The chassis intrusion circuitry can detect unauthorized intrusion to the system. The chassis intrusion connector is located on JL1. Attach a microswitch to JL1. When the microswitch is closed, it means that the chassis has been opened. The circuitry will then alert the user with a

Page 33

Chapter 1: Introduction

1-23

warning message when the system is turned back on. This feature is available when the user is running Intel's LANDesk Client Manager and SUPERMICRO's Super Doctor.

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager (optional). It is used to notify the user of certain system events. For example, if the system is running low on virtual memory and there is insufficient hard drive space for saving the data, you can be alerted of the potential problem.

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 switching voltage regulator for the CPU core can support up to 20A current, with the auto-sensing voltage ID ranging from 1.4V to 3.5V. This will allow the regulator to run cooler and thus make the system more stable.

Intel LANDesk® Client Manager (LDCM) Support

As the computer industry grows, PC systems become more complex and harder to manage. Historically, only experts have been able to fully understand and control these complex systems. Today's users want manageable systems that they can interact with automatically. Client Manager enables both administrators and clients to:

• Review system inventory

• View DMI-compliant component information

• Back up and restore system configuration files

• Troubleshoot

• Receive notifications of system events

• Transfer files to and from client workstations

• Remotely reboot client workstations

1-5 ACPI/PC 98 Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a PC system, including hardware, operating system and application software. This enables the system to automatically turn on and off peripherals such as CD-ROMs, network cards, hard disk drives and printers.

In addition to enabling operating system-directed power management, ACPI provides a generic system event mechanism for Plug and Play and an operating system-independent interface for configuration control. ACPI leverages the Plug and Play BIOS data structures while providing a processor architecture-independent implementation that is compatible with Windows98. In order to enable ACPI, the default APM mode must be disabled in BIOS (see page 5-13). To install Windows 98 with ACPI, enter DOS and type "setup /p j" at the CDROM prompt (usually D:\) with the Windows98 CD loaded. (Make sure you include the spaces after "setup" and "p".) Then hit <Enter>. You can check to see if ACPI has been properly installed by looking for it in the Device Manager, which is located in the Control Panel in Windows.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide approach to system and device power control. OnNow is a term for a PC that is always on but appears to be off and responds immediately to user or other requests.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the power LED will start blinking to indicate that the CPU is in suspend mode. When the user presses any key, the CPU will wake-up and the LED will automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, the USB keyboard will work like a normal keyboard during system boot-up.

Page 36

SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM Manual

1-26

Real Time Clock Wake-Up Alarm

Although the PC may be perceived to be off when not in use, it is still capable of responding to preset wake-up events. In the BIOS, the user can set a timer to wake-up the system at a predetermined time (see page 5-15).

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 on the power button, the system will enter a SoftOff state. The monitor will be suspended and the hard drive will spin down. Depressing the power button again will cause the whole system to wake-up. During the SoftOff state, the ATX power supply provides power to keep the required circuitry in the system alive. In case the system malfunctions and you want to turn off the power, just depress and hold the power button for 4 seconds. The power will turn off and no power will be provided to the motherboard.

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing when the system is in the SoftOff state. Note that external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply.

1-6 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. Note that Wake-On-Lan can only be used with an ATX 2.01 (or above) compliant power supply.

1-8 Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly reduces the number of components required for interfacing with floppy disk drives. The Super I/O supports four 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.

It also provides two high speed serial communication ports (UARTs), one of which supports serial infrared communication. Each UART includes a 16byte send/receive FIFO, a programmable baud rate generator, complete modem control capability and a processor interrupt system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.

The Super I/O supports one PC-compatible printer port (SPP), Bi-directional Printer Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP). Extension FDD and Extension 2FDD Modes are also available through the printer port interface pins to allow one or two external floppy disk drives to be connected.

1-7 Power Supply

As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for Pentium II and III processors that have high CPU clock rates of 300 MHz and above.

The SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM accommodates ATX power supplies. Although most power supplies generally meet the specifications required by the CPU, some are inadequate.

It is highly recommended that you use a high quality power supply that meets ATX power supply Specification 2.01. 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.

1-9 AIC-7895 MultiChannel

Single-Chip UltraSCSI

The SUPER P6DBS/P6SBS has an onboard SCSI controller that is 100% compatible with all major operating and hardware platforms. PCI 2.1 and SCAM Level 1 compliance are assured. Two independent UltraSCSI channels provide a per channel data transfer rate of 40 MB/s. Connectors include two 68-pin 16-bit Ultra Wide SCSI connectors (JA1/JA2) and a 50pin 8-bit Ultra SCSI connector (JA3). You can connect up to 15 devices (seven 8-bit internal and eight 16-bit internal or external SCSI devices, or 15 wide internal and external SCSI devices).

When Fast SCSI devices are connected, the total length of all cables (internal and external) must not exceed 3 meters (9.8 ft) to ensure reliable operation. If no Fast SCSI devices are connected, the total length of all cables must not exceed 6 meters (19.7 ft).

The AIC-7895 consolidates the functions of two SCSI chips, eliminating the need of a PCI bridge. Reducing PCI bus loading allows you to expand your system capabilities with additional PCI devices.

The AIC-7895 functions with Adaptec RAIDport II (ARO1130SA/CA) to deliver RAID functionality. For information on installing onboard SCSI under Windows NT, refer to pages 3-6 and 3-7 in the FAQ section of this manual.

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 Super I/O complies with the Microsoft PC98 Hardware Design Guide. IRQs, DMAs and I/O space resources can flexibly adjust to meet ISA PnP requirements. Moreover, it meets the specifications of PC98's power management requirements: ACPI and APM (Advanced Power Management).

Chapter 1: Introduction

1-29

1-10 AIC-7890 Ultra II SCSI

Note: If you are using a low voltage differential hard drive, it is recommended that you use an LVD/SE Ultra II SCSI cable. LVD/SE cables offer increased length and can accommodate more devices.

The SUPER P6DBU/P6SBU has an onboard SCSI controller that is 100% compatible with all major operating and hardware platforms. The AIC-7890 controller provides advanced PCI-to-SCSI Ultra II SCSI host adapter features in a 272-pin Ball Grid Array (BGA) package, as well as containing an integrated dual mode (LVD/SE) transceiver. The AIC-7890 Ultra II SCSI chip connects to a 32-bit PCI bus. It is PCI 2.1 compliant, it fully supports the power management requirements specified in the Microsoft PC 97 guidelines and it provides SCAM level 2 support. The AIC-7890 functions with Adaptec RAIDport III (ARO-1130U2) to deliver RAID functionality.

Ultra II SCSI enables faster data rates and longer cable lengths on the SCSI bus. It doubles the data burst rate of Ultra Wide SCSI to 80 Mb/s for greater system throughput. It also quadruples the maximum cable length of Ultra Wide SCSI to 12 meters and allows up to 15 SCSI devices to be connected. For information on installing onboard SCSI under Windows NT, refer to pages 3-6 and 3-7 in the FAQ section of this manual.

3. Slide a black plastic support onto each end of the fan/heat sink making sure that the hole and clip are on the outside edge of the support. If the supports are reversed, the holes will not line up with the pegs on the motherboard. Slide each support toward the center of the processor until the support is seated in the outside groove in the fan housing.

4. Slide the clip (A) on each support toward the processor, exposing the hole that will fit over the peg on the motherboard. Push the latches (B) on the processor toward the center of the processor until they click into place.

5. Hold the processor so that the fan shroud is facing toward the pegs on the motherboard. Slide the processor (C in Figure 2-2) into the retention mechanism and slide the supports onto the pegs. Ensure that the pegs on the motherboard slide into the holes in the heat sink support and that the

Do not screw in too tight!

6. Slide the clips on the supports (A) forward until they click into place to hold

the pegs securely. Apply slight pressure on the peg and push the peg toward the clip while pushing the clip forward. Push the latches on the processor (B) outward until they click into place in the retention mechanism. The latches must be secured for the proper electrical connection of the processor.

Heat Sink

Note: New Pentium III 600E/600EB MHz and faster processors use the

0.18µm process and have a lower CPU core voltage. (“B” is to differenti-

ate 133 MHz front side bus processors from 100 MHz front side bus processors of the same speed. “E” is to differentiate 0.18-micron from

0.25-micron processors of the same speed.)

2-3 Installation of the Universal Retention

Mechanism (URM)*

Please Note! Screws and washers attach from the bottom of the board and must be installed before mounting the board to the chassis. (See Figures 2-4 and 2-5.)

1. When installing the URM, be sure the

Left

(L) and

Right

(R) sides are

placed accordingly.**

2. Lift both arms upright and slide the processor into the socket, noting that

the notches need to line up.

*These directions may not apply to second source URMs ** Newer URMs are not left/right specific. Also, caps are only needed for SECC2 cartridges.

2-4 Special Instructions for the Celeron Processor

Please Note! The Celeron processor requires special caps to hold it in place (these caps are bundled with the motherboard). (See

Figures 2-4 and 2-5.)

1. Lift both URM arms to their upright positions.

2. Slide the Celeron processor into the socket making sure that the

notches line up.

3. Slide the special Celeron caps over the ends of the retention arms.

Make sure the arrows face outward and that the

Left

(L) and

Right

(R) caps are on the appropriate sides of the URM. The caps should snap into place.

4. To remove the caps, pull out on the tab (arrows points to tab) and then pull up.

2-5 Explanation and

Diagram of Jumper/ Connector

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.

2-6 Changing the CPU

Speed

To change the CPU speed for a Pentium III/II processor, change the jumpers shown in Table 2-1. The example on the right will show you which CPU Core/Bus Ratio to use. The general rule is to divide the CPU speed by the bus speed (100 MHz in this example). If you have a 400 MHz CPU, dividing it by 100 will give you a CPU Core/BUS Ratio of 4.0. After determining the CPU Core/Bus Ratio, refer to Table 2-1 for the correct settings of JB1, JB2, JB3 and JB4.

2-7 Mounting the Motherboard in the Chassis

All the motherboards have standard mounting holes to fit different types of chassis. Chassis may come with a variety of mounting fasteners made of metal or plastic. Although a chassis may have both metal and plastic fasteners, metal fasteners are the most highly recommended because they ground the system board to the chassis. Therefore, use as many metal fasteners as possible for better grounding.

2-8 Connecting Cables

Power Supply Connector

After you have securely mounted the motherboard to the chassis, you are ready to connect the cables. See page 1-27 for

power supply requirements.

2-10 Connecting Parallel Port, Floppy and Hard Disk Drives

Use the following information to connect the floppy and hard disk drive cables.

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two connectors to provide for two floppy disk drives. The connector with twisted wires always connects to drive A, and the connector that does not have twisted wires always connects to drive B.

• An IDE hard disk drive requires a data ribbon cable with 40 wires, and a SCSI hard disk drive requires a SCSI ribbon cable with 50 wires. A wide SCSI hard disk drive requires a SCSI ribbon cable with 68 wires.

• A single IDE hard disk drive cable has two connectors to provide for two drives. To select an IDE disk drive as C, you would normally set the drive select jumper on the drive to DS1 (or Master). To select an IDE disk drive as D, you would normally set the drive select jumper on the drive to DS2 (or Slave). Consult the documentation that came with your disk drive for details on actual jumper locations and settings.

• A single SCSI ribbon cable typically has three connectors to provide for two hard disk drives and the SCSI adapter. (Note: most SCSI hard drives are single-ended SCSI devices.) The SCSI ID is determined by jumpers or a switch on the SCSI device. The last internal (and external) SCSI device cabled to the SCSI adapter must be terminated.

No Power

1. Make sure that the default jumper is on and the CPU is correctly set up.

2. Check the power supply voltage monitor. (Check the power supply 115V/230V switch.)

3. If the power is still not on, turn off the system power and move the jumper setting on JP20 from 2-3 to 1-2.

4. Turn the power switch on and off to test the system.

5. If changing the jumper setting has not helped, clear CMOS.

No Video

Use the following steps for troubleshooting your system configuration.

1. If the power is on but you have no video, remove all the add-on cards and cables.

2. Check for shorted connections, especially under the motherboard.

3. Check the jumpers settings, clock speed and voltage settings.

4. Use the speaker to determine if any beep codes exist. Refer to Appendix A for details about beep codes.

NOTE

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

card is recommended. For port 80h codes, refer to Appendix B.

Memory Errors

If you encounter a memory error, follow the procedures below.

1. Check to determine if the DIMM modules are improperly installed.

2. Make sure that different types of DIMMs have not been installed in different banks (e.g., a mixture of 2MB x 36 and 1 MB x 36 DIMMs in Bank 0).

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

4. Check for bad DIMM modules or chips.

5. Try to install the minimum amount of memory first (a single bank).

3-3 Frequently Asked Questions

Question: I have a large IDE hard drive but it's only recognized as being 8 GB in size when I let the BIOS auto detect it. What's wrong?

Answer: The auto detect feature in WinBIOS only shows hard drives as having

a maximum capacity of 8 GB. This is a BIOS limitation, but will not impact your system. If you go to the information status table, you will see that the correct size of your hard disk drive has been recognized.

Question: What are the differences between the various memories that the 440BX motherboard can support?

Answer: The 440BX integrates a main memory DRAM controller that sup-

ports a 64-bit or 72-bit (64 bit memory data plus 8 ECC bits.) DRAM from 8 MB to 512 MB for SDRAM and from 8 MB to 1 GB for EDO or registered DIMM. The DRAM types supported are either Extended Data Out (EDO), Synchronous DRAM (SDRAM) or Registered DIM modules.

*Note: EDO

DIMMs are not recommended for running at 100 MHz bus speed.

1. Mixing ECC and non-ECC memory will result in non-ECC operation.

EC/ECC is supported by the 440BX only if all the memory is 72 bits wide. A system with a mixture of 64 and 72-bit wide memory will disable the ECC mode.

2. EDO memory and SDRAM cannot be mixed.

3. Registered SDRAM and unbuffered SDRAM cannot be mixed.

4. Mixing PC/100 DIMMs with PC/66 DIMMs will result in an unexpected memory count or system errors.

5. The user should populate the DIMMs starting with the DIMM slot located farthest from the BX chip (U2 on P6DBS/P6DBE/P6SBS, U4 on P6DBU/ P6SBU or U9 on P6SBA).

6. If EDO memory is used, the CPU bus should be set to 66 MHz only.

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

Page 63

3-5

Chapter 3: Troubleshooting

message and the info on how to update it on our web site. Also, check the current BIOS revision and make sure it is newer than your BIOS before downloading. Select your motherboard model and download the BIOS file to your computer. Unzip the BIOS update file and you will find the readme.txt (flash instructions), the sm2flash.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 "sm2flash." This will start the flash utility and give you an opportunity to save your current BIOS image. Flash the boot block and enter the name of the update BIOS image file. NOTE: It is important to save your current BIOS and rename it "super.rom" in case you need to recover from a failed BIOS update. Select flash boot block, then enter the update BIOS image. Select "Y" to start the BIOS flash procedure and do not disturb your system until the flash utility displays that the procedure is complete. After updating your BIOS, please clear the CMOS then load Optimal Values in the BIOS.

Question: After flashing the BIOS my system does not have video. How can I correct this?

Answer: If the system does not have video after flashing your new BIOS,

it indicates that the flashing procedure failed. To remedy this, first clear CMOS per the instructions in this manual and retry the BIOS flashing procedure. If you still do not have video, please use the following BIOS recovery procedure. First, make sure the JPWAKE jumper is disabled (on P6SBM only). 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.

Question: I have memory problems. What is the correct memory to use and which BIOS setting should I choose?

Answer: The correct memory to use on the SUPER P6DBS/P6DBE/P6DBU/

P6SBU/P6SBS/P6SBA is 168-pin DIMM 3.3v non-buffered SPD (Serial Present Detection) SDRAM, SDRAM and EDO memory. SPD SDRAM is preferred but is not necessary. IMPORTANT: Do not mix memory types; the results are unpredictable. If your memory count is exactly half of the correct value, go to the Chipset Setup in BIOS and set "SDRAM AUTOSIZING SUPPORT" to

Enabled

. Toggle between the available options until one setting correctly

displays the amount of memory installed.

SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM Manual

Question: Which Operating System (OS) supports AGP?

Answer: At present, Windows 98 and Windows NT 5.0 are the only OS

that have built-in support for AGP. Some AGP video adapters can run Windows 95 OSR2.1 with special drivers. Please contact your graphics adapter vendor for more details.

Question: Do I need the CD that came with your motherboard?

Answer: The supplied compact disc has quite a few drivers and programs

that will greatly enhance your system. We recommend that you review the CD and install the applications you need. Applications included on the CD are PCI IDE Bus Master drivers for Windows 95 and Windows NT, 440BX chipset drivers for Windows 95, and Super Doctor Monitoring software.

Question: How do I install an onboard SCSI device controller for my P6DBS/P6SBS motherboard?

Answer: First, install the 3 NT installation disks and then follow the

onscreen instructions to complete the procedure. "Safe mode" is best for this installation.

Question: Why can't I turn off the power using the momentary power on/off switch?

Answer: The instant power off function is controlled by the BIOS. When

this feature is enabled in the BIOS, the motherboard will have instant off capabilities as long as the BIOS has control of the system. When this feature is disabled 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 the system down. This feature is required to implement the ACPI features.

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.

Chapter 3: Troubleshooting

Question: When I connect my Ultra II LVD hard drive on the JA1 SCSI connection, the drive was not recognized by BIOS or it failed to boot. Do I need a special cable?

Answer: Yes, for an Ultra II LVD hard drive you need a special 68-pin

cable with an active termination at the end of the cable, since Ultra II LVD hard drives do not have termination on the drive.

Question: How do I install the sound driver for the built-in ES1938 AudioDrive?

Answer: Insert the Supermicro CD that came with the motherboard into your CD-

ROM drive. Double click on your CD-ROM icon (which can be found in "My Computer") to access the CD, then double click on the red "S" icon named "setup.exe". The Set Up menu will appear. From this menu, select "Set Up Applications " and choose the program you wish to install. For WindowsNT installation, see the readme file in the Set Up menu.

Question: I successfully installed the AudioDrive utility, but can only hear sound from one of my speakers. What is the problem?

Answer: Go to the Advanced Settings in the volume control panel of the

utility and enable the "3D Effect" option. This should result in full stereo sound.

Question: Why do I get the error message "Stop 0x0000007B Inaccessible Boot Device" during the Windows NT 4.0 Hardware Detection Portion of Setup?

Answer: When you run Windows NT Setup, you may receive the following

error message during the hardware detection phase: STOP:0x0000007B Inaccessible Boot Device. This behavior can occur if your computer contains a motherboard with an onboard Adaptec Dual-Channel Ultra Wide 7895 Small Computer System Interface (SCSI) controller. This controller is not on the Windows NT Hardware Compatibility List (HCL) and is not detected correctly by Windows NT Setup. To resolve this issue, follow these steps:

1. Insert the Windows NT Setup disk 1 in drive A and then turn on or restart

the computer.

2. When you are prompted to specify the mass storage devices, press S.

3. Provide the driver disks included with the motherboard.

AMIBIOS

4-1 Introduction

This chapter describes the AMIBIOS for the Intel 440BX Pentium II 233/266/ 300/333/350/400/450 MHz and Pentium III MHz processors. The AMI ROM BIOS is stored in the Flash EEPROM and can be easily upgraded using a floppy disk-based program.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and PS/2® compatible computers. WinBIOS is a high-quality example of a system BIOS.

Configuration Data

AT-compatible systems, also called ISA (Industry Standard Architecture) must have a place to store system information when the computer is turned off. The original IBM AT had 64 kbytes of non-volatile memory storage in CMOS RAM. All AT-compatible systems have at least 64 kbytes of CMOS RAM, which is usually part of the Real Time Clock. Many systems have 128 kbytes of CMOS RAM.

How Data Is Configured

AMIBIOS provides a Setup utility in ROM that is accessed by pressing <Del> at the appropriate time during system boot. Setup configures data in CMOS RAM.

POST Memory Test

Normally, the only visible POST routine is the memory test. The screen that appears when the system is powered on is shown on the next page.

An AMIBIOS identification string is displayed at the left bottom corner of the screen, below the copyright message.

Parameter Description

Type The number for a drive with certain identification parameters.

Cylinders The number of cylinders in the disk drive.

Heads The number of heads.

Write The size of a sector gets progressively smaller as the track

Precompensation diameter diminishes. Yet each sector must still hold 512 bytes.

Write precompensation circuitry on the hard disk compensates for the physical difference in sector size by boosting the write current for sectors on inner tracks. This parameter is the track number where write precompensation begins.

Sectors The number of sectors per track. MFM drives have 17 sectors

per track. RLL drives have 26 sectors per track. ESDI drives have 34 sectors per track. SCSI and IDE drive may have even more sectors per track.

Capacity The formatted capacity of the drive is (Number of heads) x

(Number of cylinders) x (Number of sectors per track) x (512 bytes per sector)

- In an ECC configuration, the 82443BX asserts SERR#, for single bit (correctable) ECC errors or multiple bit (non-correctable) ECC errors if SERR# signaling is enabled via the ERRCMD control register. Any ECC errors received during initialization should be ignored.

- The 82443BX asserts SERR# for one clock when it detects a target abort during 82443BX initiated PCI cycle

- The 82443BX can also assert SERR# when a PCI parity error occurs during the address or data phase

- The 82443BX can assert SERR# when it detects a PCI address or data parity error on AGP

- The 82443BX can assert SERR# upon detection of access to an invalid entry in the Graphics Aperature Translation Table

- The 82443BX can assert SERR# upon detecting an invalid AGP master access outside of AGP aperture and outside of main DRAM range (i.e. in the 640k - 1M range or above TOM)

Setting Description

None No error checking or error reporting is done.

EC Multibit errors are detected and reported as parity

errors. Single-bit errors are corrected by the chipset. Corrected bits of data from memory are not written back to DRAM system memory.

ECC Multibit errors are detected and reported as parity Hardware errors. Single-bit errors are corrected by the

chipset and are written back to DRAM system memory. If a soft (correctable) error occurs, writing the fixed data back to DRAM system memory will resolve the problem. Most DRAM errors are soft errors. If a hard (uncorrectable) error occurs, writing the fixed data back to DRAM system memory does not solve the problem. In this case, the second time the error occurs in the same location, a Parity Error is reported, indicating an uncorrectable error. If ECC

BIOS Error Beep Codes & Messages

During the POST (Power-On Self-Test) routines, which are performed each time the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue the boot-up process. The error messages normally appear on the screen.

Fatal errors are those which will not allow the system to continue the boot-up procedure. If a fatal error occurs, you should consult with your system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of audible beeps. The numbers on the fatal error list, on the following page, correspond to the number of beeps for the corresponding error. All errors listed, with the exception of #8, are fatal errors.
