Power Management Event signal (PME#) wake-up support
1.11.1 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 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

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

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.

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
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
Product Description
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).

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. 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.

NOTE
✏
In PIC mode, the ICH5 can connect each PIRQ line internally to one of the IRQ signals (3, 4, 5, 6,
7, 9, 10, 11, 12, 14, and 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.

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)

Intel Desktop Board D865PCD Technical Product Specification
2.11 Electrical Considerations
2.11.1 DC Loading
Table 30 lists the DC loading characteristics of the board. 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.

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
The ATX form factor specification
Section 1.3, page 16
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:

3.1 Introduction
The Desktop Board D865PCD uses an Intel/AMI BIOS that is stored in the Firmware Hub (FWH)
and can be updated using a disk-based program. 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 poweredup, 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
• 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.
®
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

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 <F12> 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

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
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.
Rapid BIOS
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).

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 <Enter> 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.
