Product Description 1.12.1 ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the Desktop Board D875PBZ requires an operating system that provides full ACPI support.
Intel Desktop Board D875PBZ Technical Product Specification 1.12.1.1 System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off.
Product Description 1.12.1.2 Wake-up Devices and Events Table 10 lists the devices or specific events that can wake the computer from specific states. Table 10.
Intel Desktop Board D875PBZ Technical Product Specification 1.12.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off).
Product Description 1.12.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface.
Intel Desktop Board D875PBZ Technical Product Specification 1.12.2.5 Standby Power (+5 V) Indicator LED CAUTION If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the Desktop Board D875PBZ. Failure to do so could damage the Desktop Board D875PBZ and any attached devices. The standby power indicator LED shows that power is still present even when the computer appears to be off.
Product Description 1.12.2.7 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1 or S3 state. 1.12.2.8 PME# Wake-up Support When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).

Intel Desktop Board D875PBZ Technical Product Specification 2.6 Interrupts The interrupts can be routed through either the Programmable Interrupt Controller (PIC) or the Advanced Programmable Interrupt Controller (APIC) portion of the ICH5-R component. The PIC is supported in Windows 98 SE and Windows ME, and uses the first 16 interrupts. The APIC is supported in Windows 2000 and Windows XP, and supports a total of 24 interrupts. Table 16.
Technical Reference 2.7 PCI Interrupt Routing Map This section describes interrupt sharing and how the interrupt signals are connected between the PCI bus connectors and onboard PCI devices. The PCI specification specifies how interrupts can be shared between devices attached to the PCI bus. In most cases, the small amount of latency added by interrupt sharing does not affect the operation or throughput of the devices.

3 Overview of BIOS Features What This Chapter Contains 3.1 3.2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 3.10 Introduction.................................................................................................................85 BIOS Flash Memory Organization ..............................................................................85 Resource Configuration ..............................................................................................86 System Management BIOS (SMBIOS) .......................
Intel Desktop Board D875PBZ Technical Product Specification 3.3 Resource Configuration 3.3.1 PCI Autoconfiguration The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources.
Overview of BIOS Features 3.4 System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components.
Intel Desktop Board D875PBZ Technical Product Specification 3.5 Legacy USB Support Legacy USB support enables USB devices such as keyboards, mice, and hubs to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2.
Overview of BIOS Features ✏ NOTE Review the instructions distributed with the upgrade utility before attempting a BIOS update. For information about Refer to The Intel World Wide Web site Section 1.2, page 16 3.6.1 Language Support The BIOS Setup program and help messages are supported in six languages: US English, German, Italian, French, Spanish, and Japanese. Only two languages (US English and another language) can be loaded on the board at one time.
Intel Desktop Board D875PBZ Technical Product Specification ✏ NOTE Even if the computer is configured to boot from an LS-120 diskette (in the Setup program’s Removable Devices submenu), the BIOS recovery diskette must be a standard 1.44 MB diskette not a 120 MB diskette. For information about Refer to The BIOS recovery mode jumper settings Section 2.9.1, page 72 The Boot menu in the BIOS Setup program Section 4.3, page 97 Contacting Intel customer support Section 1.2, page 16 3.
Overview of BIOS Features 3.8.4 Changing the Default Boot Device During POST Pressing the key during POST causes a boot device menu to be displayed. To use this key during POST, the User Access Level in the BIOS Setup program’s Security menu must be set to Full. For information about Refer to The BIOS Setup program’s Security menu Table 66, page 116 The menu displayed after pressing the key lists the available boot devices (as set in the BIOS Setup program’s Boot Device Priority submenu).
Intel Desktop Board D875PBZ Technical Product Specification 3.9.2 Intel Rapid BIOS Boot Use of the following BIOS Setup program settings reduces the POST execution time. In the Boot menu: • • • Set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time. Disable Quiet Boot, which eliminates display of the logo splash screen.
Overview of BIOS Features 3.10 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: • • • • • The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode.

Intel Desktop Board D875PBZ Technical Product Specification Table 75. BIOS Error Messages (continued) Error Message Explanation Checking NVRAM..... NVRAM is being checked to see if it is valid. Update OK! NVRAM was invalid and has been updated. Updated Failed NVRAM was invalid but was unable to be updated. Keyboard Error Error in the keyboard connection. Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed.
Error Messages and Beep Codes 5.2 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
