24  
 
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  
INTEGRATORS 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.  
For information about  
Refer to  
The location of the AGP connector

1.6.2 USB  
The board supports up to six USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-  
compatible drivers.  
The ICH5 provides the USB controller for all ports. The port arrangement is as follows:  
Two ports are implemented with stacked back panel connectors, adjacent to the PS/2  
connectors  
Two ports are implemented with stacked back panel connectors, adjacent to the audio  
connectors  
Two ports are routed to a front panel USB connector  
NOTES  
Computer systems that have an unshielded cable attached to a USB port may not meet FCC  
Class B requirements, even if no device is attached to the cable. Use shielded cable that meets  
the requirements for full-speed devices.  
Native USB 2.0 support has been tested with drivers for Windows* 2000 (with Service Pack 3)  
and Windows XP (with Service Pack 1) and is not currently supported by any other operating  
system. Check Intels Desktop Board website for possible driver updates for other operating  
systems.

Intel Desktop Board D865PCD Technical Product Specification  
1.6.3 IDE Support  
The board provides two Parallel ATA IDE connectors, which support a total of four devices (two  
per connector). The ICH5s Parallel ATA IDE controller has two independent bus-mastering  
Parallel ATA IDE interfaces that can be independently enabled. The Parallel ATA IDE interfaces  
support the following modes:  
Programmed I/O (PIO): processor controls data transfer.  
8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec.  
Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates  
of up to 33 MB/sec.  
ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of  
up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible.  
ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH5s ATA-100  
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.  
NOTE  
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections,  
noise, and inductive coupling.  
The Parallel ATA IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA  
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS)  
translation modes. The drive reports the transfer rate and translation mode to the BIOS.  
The board supports Laser Servo (LS-120) diskette technology through the Parallel ATA IDE  
interfaces. An LS-120 drive can be configured as a boot device by setting the BIOS Setup  
programs Boot menu to one of the following:  
ARMD-FDD (ATAPI removable media device floppy disk drive)  
ARMD-HDD (ATAPI removable media device hard disk drive)  
For information about  
Refer to  
The location of the Parallel ATA IDE connectors  
1.6.4 Real-Time Clock, CMOS SRAM, and Battery  
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer  
is not plugged into a wall socket, the battery has an estimated life of three years. When the  
computer is plugged in, the standby current from the power supply extends the life of the battery.

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.

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 computers response can be set using the Last Power State  
feature in the BIOS Setup programs 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  
S3 state.  
The Desktop Board D865PCD supports the PCI Bus Power Management Interface Specification.  
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).

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  
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.

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  
allocation of PIRQ lines to IRQ signals in APIC mode.

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 computers chassis, such as fans and internal peripherals. Do not use these connectors  
to power devices external to the computers 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 boards connectors. The connectors can be divided into these groups:  
PS/2 keyboard and mouse  
USB (four ports)  
Parallel port  
Serial port A  
LAN  
Audio (line out, line in, and mic in)  
Audio (ATAPI CD-ROM and front panel audio)  
Fans [three]  
Power  
Add-in boards (PCI and AGP)  
Parallel ATA IDE

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

2.11 Electrical Considerations  
2.11.1 DC Loading  
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 boards 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 systems  
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.

2.12 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:  
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.

The Mean Time Between Failures (MTBF) prediction is calculated using component and  
subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction  
Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBF prediction is used to estimate  
repair rates and spare parts requirements.  
The MTBF data is calculated from predicted data at 55 ºC. The Desktop Board D865PCD MTBF

3 Overview of BIOS Features  
What This Chapter Contains  
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 Boardscompliance 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.  
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  
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.  
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 Boardscompliance 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 systems 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 systems 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  
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  
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 programs  
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

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  
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 programs Security menu must be  
set to Full.  
For information about  
Refer to  
The BIOS Setup programs Security menu  
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 <F10> 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 programs Boot Device Priority

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 readyless 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).

Refer to  
Drive Configuration Submenu in the BIOS Setup program

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 <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.

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.  
NOTE  
The POST card must be installed in PCI bus connector 1.  
codes are repeated in the tables because that code applies to more than one operation.

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  
that is being executed.

Refer to  
The location of the onboard speaker on the Desktop Board D865PCD  
5.5 BIOS Beep Codes  
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing  
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.
