Product Description

AGP is a high-performance interface for graphics-intensive applications, such as 3D applications.

While based on the PCI Local Bus Specification, Rev. 2.2, AGP is independent of the PCI bus and

is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of

the PCI bus related to handling large amounts of graphics data with the following features:

•

Pipelined memory read and write operations that hide memory access latency

Demultiplexing of address and data on the bus for nearly 100 percent efficiency

INTEGRATOR’S NOTES

•

AGP 2x operation is not supported.

Install memory in the DIMM sockets prior to installing the AGP video card to avoid

interference with the memory retention mechanism.

•

The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP 2.0 cards only.

Do not attempt to install a legacy 3.3 V AGP card. The AGP connector is not mechanically

compatible with legacy 3.3 V AGP cards.

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

ACPI is configured with an ACPI-aware operating system.

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.

will enable a wake-up event from LAN in the S5 state.

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.

The ATX12V, SFX12V, and TFX12V specifications

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.

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).

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.

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.

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.

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.

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)

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 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

3.2 BIOS Flash Memory Organization

The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device.

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

drives, and Ultra DMA drives (see Section 1.3 for the supported version of ATAPI). The BIOS

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

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.

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

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.

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

3.6.1 Language Support

German, Italian, French, and Spanish. The default language is US English, which is present unless

another language is selected in the BIOS Setup program.

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.

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.

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.
