Performance Acceleration Technology (PAT) provides optimum memory pathways to enhance memory performance; it requires processors with 800 FSB frequency and DDR400 memory.

Related Links:

For information about installing the AGP card, see page 37 in Chapter 2.

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.

The BIOS can be updated by following the instructions on page 53 in Chapter 3.

Page 21

Desktop Board Features

PCI Auto Configuration

If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card.

IDE Auto Configuration

If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing an IDE device. You can override the autoconfiguration options by specifying manual configuration in the BIOS Setup program.

To use ATA-66/100 features, the following items are required:

• An ATA-66/100 peripheral device

• An ATA-66/100 compatible cable

• ATA-66/100 operating system device drivers

Security Passwords

The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the Setup and for booting the computer, with the following restrictions:

• The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives the user restricted access to Setup.

• If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered.

• Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer.

Page 22

Intel Desktop Board D875PBZ Product Guide

Power Management Features

Power management is implemented at several levels, including:

• Software support through Advanced Configuration and Power Interface (ACPI) and Advanced Power Management (APM)

• Hardware support:  Suspend to RAM (Instantly Available PC technology)  Power connectors  Fan connectors  Chassis intrusion  Resume on Ring  Wake from USB  Wake from PS/2 keyboard/mouse  PME# wakeup support

ACPI

ACPI gives the operating system direct control over the power management and Plug & Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support.

APM

APM makes it possible for the computer to enter an energy-saving standby mode. The standby mode can be initiated in the following ways:

• Time-out period specified in the BIOS Setup program

• From the operating system, such as the standby menu item in Windows 98SE

In standby mode, the board may reduce power consumption by spinning down hard drives, and reducing power to or turning off of VESA* DPMS-compliant monitors. APM can be enabled or disabled in the BIOS Setup program. While in standby mode, the system retains the ability to respond to external interrupts and service requests, such as incoming faxes or network messages. Any keyboard or mouse activity brings the system out of standby mode and immediately restores power to the monitor.

Suspend to RAM (Instantly Available PC Technology)

CAUTION

For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up device or event, the system quickly returns to its last known awake state.

Page 23

Desktop Board Features

The desktop board’s standby power indicator, shown in Figure 2, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors, even when the computer appears to be off.

If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.

CR7J1

OM15682

Figure 2. Location of the Standby Power Indicator

CAUTION

Power supplies used with this desktop board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory.

For more information on standby current requirements for these desktop boards, refer to the TPS by selecting the Technical Documentation link at:

http://developer.intel.com/design/motherbd/

Power Connectors

The desktop board has two power connectors. See Figure 14 on page 46 for the location of the power connectors.

Fan Connectors

The desktop board has three chassis fan connectors and one processor fan connector. See Figure 14 on page 46 for the location of the fan connectors.

Related Links:

Go to page 46 for the location of the fan headers.

Fan Speed Control (Intel® Precision Cooling Technology)

Intel Precision Cooling Technology automatically adjusts the chassis fan speeds depending on the system’s temperature. This feature reduces system fan noise by decreasing the speed of the chassis

Page 24

Intel Desktop Board D875PBZ Product Guide

fans connected to the front and rear chassis fan connectors. The processor fan connector is not controlled.

The fan speed control feature can be disabled in the BIOS, resulting in the chassis fans always operating at full speed. This feature should be disabled if a self-controlled fan is attached to a chassis fan connector.

The overall system noise reduction will vary based on system configuration and environment.

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board.

Related Links:

3 Updating the BIOS

This chapter tells you how to update the BIOS by either using the Intel Express BIOS Update utility or the MS-DOS* based Iflash BIOS update utility, and how to recover the BIOS if an update fails.

Updating the BIOS with the Intel® Express BIOS Update Utility

With the Intel Express BIOS Update utility you can update the system BIOS while in the Windows environment. The BIOS file is included in an automated update utility that combines the functionality of the Iflash BIOS update utility and the ease-of use of Windows-based installation wizards.

To update the BIOS with the Intel Express BIOS Update utility:

1. Go to the Intel World Wide Web site:

http://support.intel.com/support/motherboards/desktop/

2. Navigate to the Desktop Board D875PBZ page and click the Express BIOS Update utility file for the Desktop Board D875PBZ BIOS.

3. Download the file to your hard drive. (You can also save this file to a diskette. This is useful if you are updating the BIOS for multiple identical systems.)

4. Close all other applications. This step is required. Your system will be rebooted at the last Express BIOS Update window.

5. Double-click the executable file from the location on your hard drive where it was saved. This runs the update program.

6. Follow the instructions provided in the dialog boxes to complete the BIOS update.

Page 54

Intel Desktop Board D875PBZ Product Guide

Updating the BIOS with the Iflash Update Utility

With the Iflash BIOS Update utility you can update the system BIOS from a floppy disk or other bootable media. The utility available from the Web provides a simple method for creating a bootable flash BIOS update floppy that will automatically update your BIOS.

Obtaining the BIOS Update File

You can update to a new version of the BIOS by using the BIOS update file. The BIOS update file is a compressed self-extracting archive that contains all the files you need to update the BIOS. The BIOS update file contains:

• New BIOS files

• BIOS recovery files

• Iflash BIOS update utility

You can obtain the BIOS update file through your computer supplier or by navigating to the Desktop Board D875PBZ page on the Intel World Wide Web site:

http://support.intel.com/support/motherboards/desktop

NOTE

Review the instructions distributed with the update utility before attempting a BIOS update.

The Iflash BIOS update utility allows you to:

• Update the BIOS in flash memory

• Update the language section of the BIOS

Updating the BIOS

CAUTION

The AUTOEXEC.BAT file provided with the update files updates the BIOS. Do not interrupt the process or the system may not function.

1. Boot the computer with the BIOS update diskette in drive A. During system boot, the AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update process.

2. When the update process is complete, the monitor will display a message telling you to remove the diskette and to reboot the system.

3. As the computer boots, check the BIOS identifier (version number) to make sure the update was successful. If a logo appears, press <Esc> to view the POST messages.

Page 55

Updating the BIOS

Recovering the BIOS

It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails. The following procedure uses recovery mode for the Setup program. See page 48 for more information on Setup modes.

NOTE

Because of the small amount of code available in the boot block area, there is no video support. You will not see anything on the screen during this procedure. Monitor the procedure by listening to the speaker and looking at the diskette drive LED.

1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external peripherals.

2. Remove the computer cover and locate the configuration jumper block (see Figure 15).

3. Remove the jumper from all pins as shown below to set recovery mode for Setup.

4. Insert the bootable BIOS update diskette into diskette drive A.

5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to boot. The recovery process will take a few minutes.

6. Listen to the speaker:

• Upon applying power, drive A will begin to show activity. In about a minute, two beeps

are heard and drive A activity ceases (temporarily) indicating the successful recovery of the BIOS core. Drive A activity will begin again followed by two more beeps indicating the successful recovery of the boot block. This sequence of events indicates a successful BIOS recovery.

• A series of continuous beeps indicates a failed BIOS recovery.

7. If recovery fails, return to step 1 and repeat the recovery process.

8. If recovery is successful, turn off the computer, and disconnect its power cord.

9. Remove the computer cover and continue with the following steps.

10. On the jumper block, reinstall the jumper back on pins 1-2 as shown below to set normal mode for Setup.

11. Leave the update diskette in drive A, replace the computer cover, and connect the computer’s power cord.

12. Turn on the computer and continue with the BIOS update.

4 Using the BIOS Setup Program

The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins.

NOTE

The BIOS Setup menus described in this section may not show the latest settings. For the latest BIOS settings, refer to the Intel Desktop Board D875PBZ Technical Product Specification or the Intel World Wide Web site:

http://support.intel.com/support/motherboards/desktop

NOTE

For reference purposes, you should write down the current Setup settings. When you make changes to the settings, update this record.

NOTE

The Setup menus described in this section apply to the desktop boards with BIOS identifier BZ87510A.86A. Boards with other BIOS identifiers might have differences in some of the Setup menu screens.

This chapter shows the location of the:

• Back panel connectors

• Add-in board and peripheral interface connectors

CAUTION

Many of the midboard and front panel connectors provide operating voltage (+5 V dc and +12 V dc, for example) to devices inside the computer chassis, such as fans and internal peripherals. These connectors are not overcurrent protected. Do not use these connectors for powering devices external to the computer chassis. A fault in the load presented by the external devices could cause damage to the computer, the interconnecting cable, and the external devices themselves.
