The use of ACPI with the Desktop Board D865PCD requires an operating system that provides full ACPI support. ACPI features include: • Plug and Play (including bus and device enumeration) • Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives • Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state • A Soft-off feature that enables the operating system to power-off the computer • Support for multiple wake-up events (see Table 9 on page 32) • Support for a front panel power and sleep mode switch Table 7 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system. Table 7. Effects of Pressing the Power Switch …and the power switch is If the system is in this state… pressed for …the system enters this state Off Less than four seconds Power-on (ACPI G2/G5 – Soft off) (ACPI G0 – working state) On Less than four seconds Soft-off/Standby (ACPI G0 – working state) (ACPI G1 – sleeping state) On More than four seconds Fail safe power-off (ACPI G0 – working state) (ACPI G2/G5 – Soft off) Sleep Less than four seconds Wake-up (ACPI G1 – sleeping state) (ACPI G0 – working state) Sleep More than four seconds Power-off (ACPI G1 – sleeping state) (ACPI G2/G5 – Soft off) For information about Refer to The Desktop Boards’ compliance level with ACPI Section 1.3, page 16 1.11.1.1 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. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 8 lists the power states supported by the Desktop Board D865PCD and along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states. 31 Intel Desktop Board D865PCD Technical Product Specification Table 8.

Total system power is dependent on the system configuration, including add-in boards and peripherals powered by the system chassis’ power supply. 2. Dependent on the standby power consumption of wake-up devices used in the system. 1.11.1.2 Wake-up Devices and Events Table 9 lists the devices or specific events that can wake the computer from specific states. Table 9. Wake-up Devices and Events These devices/events can wake up the computer… …from this state (Note) LAN S1, S3, S4, S5 Modem (back panel Serial Port A) S1, S3 (Note) PME# signal S1, S3, S4, S5 Power switch S1, S3, S4, S5 PS/2 devices S1, S3 RTC alarm S1, S3, S4, S5 USB S1, S3 Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. 32 Product Description NOTE ✏ The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events. 1.11.2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. The Desktop Board D865PCD provides several power management hardware features, including: • Power connector • Fan connectors • LAN wake capabilities • Instantly Available PC technology • Resume on Ring • Wake from USB • Wake from PS/2 keyboard • PME# signal wake-up support LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. The sections discussing these features describe the incremental standby power requirements for each. Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal). NOTE ✏ The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support. 1.11.2.1 Power Connector ATX12V-, SFX12V-, and TFX12V-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). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu. 33 Intel Desktop Board D865PCD Technical Product Specification For information about Refer to The location of the power connector Figure 9, page 46 The signal names of the power connector Table 21, page 49 The BIOS Setup program’s Boot menu Table 57, page 96 The ATX12V, SFX12V, and TFX12V specifications Section 1.3, page 16 1.11.2.2 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. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the Desktop Board D865PCD support LAN wake capabilities with ACPI in the following ways: • The PCI bus PME# signal for PCI 2.2 compliant LAN designs • The onboard LAN subsystem 1.11.2.3 Instantly Available PC Technology CAUTION For Instantly Available PC technology, 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 Instantly Available PC technology can damage the power supply. Instantly Available PC technology enables the Desktop Board D865PCD to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 9 on page 32 lists the devices and events that can wake the computer from the S3 state. The Desktop Board D865PCD supports the PCI Bus Power Management Interface Specification. For information on the version of this specification, see Section 1.3. Add-in boards that also support this specification can participate in power management and can be used to wake the computer. The use of Instantly Available PC technology requires operating system support and PCI 2.2 compliant add-in cards and drivers. 34 Product Description 1.11.2.4 Resume on Ring The operation of Resume on Ring can be summarized as follows: • Resumes operation from ACPI S1 or S3 states • Detects incoming call similarly for external and internal modems • Requires modem interrupt be unmasked for correct operation 1.11.2.5 Wake from USB USB bus activity wakes the computer from ACPI S1 or S3 states. NOTE ✏ Wake from USB requires the use of a USB peripheral that supports Wake from USB. 1.11.2.6 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1 or S3 state. 1.11.2.7 PME# Signal 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). 35 Intel Desktop Board D865PCD Technical Product Specification 36 2 Technical Reference What This Chapter Contains 2.1 Introduction.................................................................................................................37 2.2 Memory Map ..............................................................................................................37 2.3 DMA Channels ...........................................................................................................38 2.4 Fixed I/O Map.............................................................................................................38 2.5 PCI Configuration Space Map ....................................................................................39 2.6 Interrupts ....................................................................................................................40 2.7 PCI Interrupt Routing Map..........................................................................................41 2.8 Connectors.................................................................................................................43 2.9 Jumper Blocks............................................................................................................56 2.10 Mechanical Considerations.........................................................................................58 2.11 Electrical Considerations ............................................................................................60 2.12 Thermal Considerations..............................................................................................61 2.13 Reliability ....................................................................................................................63 2.14 Environmental ............................................................................................................64 2.1 Introduction Sections 2.2 - 2.6 contain several standalone tables.

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. In some special cases where maximum performance is needed from a device, a PCI device should not share an interrupt with other PCI devices. Use the following information to avoid sharing an interrupt with a PCI add-in card. PCI devices are categorized as follows to specify their interrupt grouping: • INTA: By default, all add-in cards that require only one interrupt are in this category. For almost all cards that require more than one interrupt, the first interrupt on the card is also classified as INTA. • INTB: Generally, the second interrupt on add-in cards that require two or more interrupts is classified as INTB. (This is not an absolute requirement.) • INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC and a fourth interrupt is classified as INTD. The ICH5 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI interrupt sources either onboard or from a PCI add-in card connect to one of these PIRQ signals. Some PCI interrupt sources are electrically tied together on the Desktop Boards D865PCD and therefore share the same interrupt. Table 15 shows an example of how the PIRQ signals are routed. For example, using Table 15 as a reference, assume an add-in card using INTA is plugged into PCI bus connector 3. In PCI bus connector 3, INTA is connected to PIRQB, which is already connected to the ICH5 audio controller. The add-in card in PCI bus connector 3 now shares an interrupt with the onboard interrupt source. 41 Intel Desktop Board D865PCD Technical Product Specification Table 15.

Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be connected to the same IRQ signal. Refer to Table 14 for the allocation of PIRQ lines to IRQ signals in APIC mode. 42 Technical Reference 2.8 Connectors CAUTION Only the following connectors have overcurrent protection: back panel USB, front panel USB, and PS/2. The other internal connectors are not overcurrent protected and should connect only to devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computer’s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. This section describes the board’s connectors. The connectors can be divided into these groups: • Back panel I/O connectors (see page 44)  PS/2 keyboard and mouse  USB (four ports)  Parallel port  Serial port A  LAN  Audio (line out, line in, and mic in) • Internal I/O connectors (see page 45)  Audio (ATAPI CD-ROM and front panel audio)  Fans [three]  Power  Add-in boards (PCI and AGP)  Parallel ATA IDE  Diskette drive  Chassis intrusion • External I/O connectors (see page 52)  Front panel USB (two connector for four ports)  Auxiliary front panel power/sleep/message-waiting LED  Front panel (power/sleep/message-waiting LED, power switch, hard drive activity LED, reset switch, and auxiliary front panel power LED) NOTE ✏ When installing the board in a microATX chassis, make sure that peripheral devices are installed at least 1.5 inches above the main power connector, the diskette drive connector, the Parallel ATA IDE connectors, and the DIMM sockets. 43 Intel Desktop Board D865PCD Technical Product Specification 2.8.1 Back Panel Connectors Figure 8 shows the location of the back panel connectors.

This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw. Maximum values assume a load placed on the board that is similar to a heavy gaming environment with a 500 mA current draw per USB port. These calculations are not based on specific processor values or memory configurations but are based on the minimum and maximum current draw possible from the board’s power delivery subsystems to the processor, memory, and USB ports. Use the datasheets for add-in cards, such as PCI, to determine the overall system power requirements. The selection of a power supply at the system level is dependent on the system’s usage model and not necessarily tied to a particular processor speed. Table 30. DC Loading Characteristics DC Current at: Mode DC Power +3.3 V +5 V +12 V -12 V +5 VSB Minimum loading 190.00 W 5.00 A 11.00 A 9.00 A 0.03 A 0.60 A Maximum loading 286.00 W 11.00 A 15.00 A 13.00 A 0.10 A 1.38 A 2.11.2 Add-in Board Considerations The boards are designed to provide 2 A (average) of +5 V current for each add-in board. The total +5 V current draw for add-in boards for a fully loaded Desktop Board D865PCD (all three expansion slots and the AGP slot filled) must not exceed 8 A. 2.11.3 Fan Connector Current Capability CAUTION The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation. Table 31 lists the current capability of the fan connectors. Table 31. Fan Connector Current Capability Fan Connector Maximum Available Current Processor fan 1600 mA Front chassis fan 600 mA Rear chassis fan 600 mA 60 Technical Reference 2.11.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. System integrators should refer to the power usage values listed in Table 30 when selecting a power supply for use with the board. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the following recommendations found in the indicated sections of the ATX form factor specification. • The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2) • The current capability of the +5 VSB line (Section 4.2.1.2) • All timing parameters (Section 4.2.1.3) • All voltage tolerances (Section 4.2.2) For information about Refer to Section 1.3, page 16 The ATX form factor specification 2.12 Thermal Considerations CAUTION The use of an Intel Pentium 4 processor operating above 2.80 GHz with this Intel desktop board requires the following: • A chassis with appropriate airflow to ensure proper cooling of the components on the board • A processor fan heatsink that meets the thermal performance targets for Pentium 4 processors operating above 2.80 GHz Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the desktop board. For a list of chassis that have been tested with Intel desktop boards please refer to the following website: http://developer.intel.com/design/motherbd/cooling.htm All responsibility for determining the adequacy of any thermal or system design remains solely with the reader. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance. 61 Intel Desktop Board D865PCD Technical Product Specification CAUTION Ensure that the ambient temperature does not exceed the Desktop Board’s maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.14. CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area o (item A in Figure 18) can reach a temperature of up to 85 C in an open chassis. Figure 18 shows the locations of the localized high temperature zones.

The FWH contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs are identified as RC86510A.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered- up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match. For information about Refer to The Desktop Boards’ compliance level with Plug and Play Section 1.3, page 16 3.2 BIOS Flash Memory Organization The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device. 69 Intel Desktop Board D865PCD 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. Any interrupts set to Available in Setup are considered to be available for use by the add-in card. For information about Refer to The versions of PCI and Plug and Play supported by the BIOS Section 1.3, page 16 3.3.2 PCI IDE Support If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two PCI IDE connectors with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives (see Section 1.3 for the supported version of ATAPI). The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration 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 NOTE ✏ Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive. 70 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. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: • BIOS data, such as the BIOS revision level • Fixed-system data, such as peripherals, serial numbers, and asset tags • Resource data, such as memory size, cache size, and processor speed • Dynamic data, such as event detection and error logging Non-Plug and Play operating systems, such as Windows NT*, require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. For information about Refer to The Desktop Boards’ compliance level with SMBIOS Section 1.3, page 16 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. POST begins. 3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. 71 Intel Desktop Board D865PCD Technical Product Specification To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions. NOTE ✏ Legacy USB support is for keyboards, mice, and hubs only. Other USB devices are not supported in legacy mode. 3.6 BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: ® • Intel Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a 1.44 MB diskette, or a CD-ROM, or from the file location on the Web. ® • Intel Flash Memory Update Utility, which requires creation of a boot diskette and manual rebooting of the system. Using this utility, the BIOS can be updated from a file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM. Both utilities support the following BIOS maintenance functions: • Verifying that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS. • Updating both the BIOS boot block and the main BIOS. This process is fault tolerant to prevent boot block corruption. • Updating the BIOS boot block separately. • Changing the language section of the BIOS. • Updating replaceable BIOS modules, such as the video BIOS module. • Inserting a custom splash screen. 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 15 3.6.1 Language Support The BIOS Setup program and help messages are supported in five languages: US English, German, Italian, French, and Spanish. The default language is US English, which is present unless another language is selected in the BIOS Setup program. 72 Overview of BIOS Features 3.6.2 Custom Splash Screen ® During POST, an Intel splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. A utility is available from Intel to assist with creating a custom splash screen. The custom splash screen can be programmed into the flash memory using the BIOS upgrade utility. Information about this capability is available on the Intel Support World Wide Web site. NOTE ✏ If you add a custom splash screen, it will share space with the Intel branded logo. For information about Refer to The Intel World Wide Web site Section 1.2, page 15 3.7 Recovering BIOS Data Some types of failure can destroy the BIOS. For example, the data can be lost if a power outage occurs while the BIOS is being updated in flash memory. The BIOS can be recovered from a diskette using the BIOS recovery mode. When recovering the BIOS, be aware of the following: • Because of the small amount of code available in the non-erasable boot block area, there is no video support. You can only monitor this procedure by listening to the speaker or looking at the diskette drive LED. • The recovery process may take several minutes; larger BIOS flash memory devices require more time. • Two beeps and the end of activity in the diskette drive indicate successful BIOS recovery. • A series of continuous beeps indicates a failed BIOS recovery. To create a BIOS recovery diskette, a bootable diskette must be created and the BIOS update files copied to it. BIOS upgrades and the Intel Flash Memory Update Utility are available from Intel Customer Support through the Intel World Wide Web site. 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 2.9.2, page 57 The Boot menu in the BIOS Setup program Section 4.7, page 96 Contacting Intel customer support Section 1.2, page 15 73 Intel Desktop Board D865PCD Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled. 3.8.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, ATAPI CD-ROM is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot from the next defined drive. For information about Refer to The El Torito specification Section 1.3, page 16 3.8.2 Network Boot The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed. Pressing the key during POST automatically forces booting from the LAN. 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 54, page 94 3.8.3 Booting Without Attached Devices For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present: • Video adapter • Keyboard • Mouse 3.8.4 Changing the Default Boot Device During POST Pressing the key during POST causes a boot device menu to be displayed. This menu displays the list of available boot devices (as set in the BIOS setup program’s Boot Device Priority Submenu). Table 37 lists the boot device menu options. Table 37. Boot Device Menu Options Boot Device Menu Function Keys Description <↑> or <↓> Selects a default boot device Exits the menu, saves changes, and boots from the selected device Exits the menu without saving changes 74 Overview of BIOS Features ® 3.9 Fast Booting Systems with Intel Rapid BIOS Boot These factors affect system boot speed: • Selecting and configuring peripherals properly ® • Using an optimized BIOS, such as the Intel Rapid BIOS 3.9.1 Peripheral Selection and Configuration The following techniques help improve system boot speed: • Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays. • Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time. • Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process. • Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly. 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. This could save several seconds of painting complex graphic images and changing video modes. • Enable Intel Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive. In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time. NOTE ✏ It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen. This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program). For information about Refer to Drive Configuration Submenu in the BIOS Setup program Section 4.4.4, page 85 75 Intel Desktop Board D865PCD Technical Product Specification 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. • The user password gives restricted access to view and change Setup options in the BIOS Setup program. This is the user mode. • If only the supervisor password is set, pressing the key at the password prompt of the BIOS Setup program allows the user restricted access to Setup. • If both the supervisor and user passwords are set, users can enter either the supervisor password or the user password to access Setup. Users have access to Setup respective to which password is entered. • Setting the user password restricts who can boot the computer. The password prompt will be 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, the user can enter either password to boot the computer. Table 38 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen. Table 38.

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. NOTE ✏ The POST card must be installed in PCI bus connector 1. The tables below offer descriptions of the POST codes generated by the BIOS. Table 64 defines the uncompressed INIT code checkpoints, Table 65 describes the boot block recovery code checkpoints, and Table 66 lists the runtime code uncompressed in F000 shadow RAM. Some codes are repeated in the tables because that code applies to more than one operation. Table 64. Uncompressed INIT Code Checkpoints Code Description of POST Operation D0 NMI is Disabled.

Bus Initialization Checkpoints Checkpoint Description 2A Different buses init (system, static, and output devices) to start if present. 38 Different buses init (input, IPL, and general devices) to start if present. 39 Display different buses initialization error messages. 95 Init of different buses optional ROMs from C800 to start. While control is inside the different bus routines, additional checkpoints are output to port 80h as WORD to identify the routines under execution. In these WORD checkpoints, the low byte of the checkpoint is the system BIOS checkpoint from which the control is passed to the different bus routines. The high byte of the checkpoint is the indication of which routine is being executed in the different buses. Table 68 describes the upper nibble of the high byte and indicates the function that is being executed. Table 68. Upper Nibble High Byte Functions Value Description 0 func#0, disable all devices on the bus concerned. 1 func#1, static devices init on the bus concerned. 2 func#2, output device init on the bus concerned. 3 func#3, input device init on the bus concerned. 4 func#4, IPL device init on the bus concerned. 5 func#5, general device init on the bus concerned. 6 func#6, error reporting for the bus concerned. 7 func#7, add-on ROM init for all buses. 107 Intel Desktop Board D865PCD Technical Product Specification Table 69 describes the lower nibble of the high byte and indicates the bus on which the routines are being executed.

The speaker provides audible error code (beep code) information during POST. For information about Refer to The location of the onboard speaker on the Desktop Board D865PCD Figure 1, on page 13 5.5 BIOS Beep Codes Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem (see Table 70). The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero. An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device. There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters). 108 Error Messages and Beep Codes If POST completes normally, the BIOS issues one short beep before passing control to the operating system.
