Table 5 lists the supported system bus frequency and memory speed combinations.
Table 5. Supported System Bus Frequency and Memory Speed Combinations
To use this type of DIMM… The processor's system bus frequency must be…
DDR400 800 MHz
DDR333
DDR266 800, 533, or 400 MHz
Note: When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz. This
(Note)
800 or 533 MHz
minimizes system latencies to optimize system throughput.
✏ NOTES
• Remove the AGP video card before installing or upgrading memory to avoid interference with
the memory retention mechanism.
• To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and program the chipset to accurately
configure memory settings for optimum performance. If non-SPD memory is installed, the
BIOS will attempt to correctly configure the memory settings, but performance and reliability
may be impacted or the DIMMs may not function under the determined frequency.

Intel Desktop Board D865PERC/D865PESO Technical Product Specification
1.8.1 Universal 0.8 V / 1.5 V AGP 3.0 Connector
The AGP connector supports the following:
• 4x, 8x AGP 3.0 add-in cards with 0.8 V I/O
• 1x, 4x AGP 2.0 add-in cards with 1.5 V I/O
• AGP Digital Display (ADD) cards
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.
For information about Refer to
The location of the AGP connector on the D865PERC board Figure 1, page 14
The location of the AGP connector on the D865PESO board Figure 2, page 15
Obtaining the Accelerated Graphics Port Interface Specification Section 1.5, page 18
1.8.2 USB
The boards support up to eight 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
• Four ports are routed to two separate front panel USB connectors
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 Intel’s Desktop Board website for possible driver updates for other operating
systems.

1.8.3 IDE Support
The board provides four IDE interface connectors:
• Two Parallel ATA IDE connectors, which support a total of four devices (two per connector)
• Two Serial ATA IDE connectors, which support one device per connector
1.8.3.1 Parallel ATE IDE Interfaces
The ICH5’s 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 ICH5’s 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
devices using the transfer modes listed in Section 4.4.4.1 on page 104.
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 Desktop Boards support 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
program’s 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

31
Intel Desktop Board D865PERC/D865PESO Technical Product Specification
1.8.3.2 Serial ATA Interfaces
The ICH5’s Serial ATA controller offers two independent Serial ATA ports with a theoretical
maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a
maximum of two Serial ATA devices. A point-to-point interface is used for host to device
connections, unlike Parallel ATA IDE which supports a master/slave configuration and two
devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the operating system.
The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard
IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI resource

standby line. The sections discussing these features describe the incremental standby power
requirements for each.
44
Product Description
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.
1.13.2.1 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.

1.13.2.3 LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line for the power supply must be capable of
providing adequate +5 V standby current. Failure to provide adequate standby current when
implementing LAN wake capabilities can damage the power supply.
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN
subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface.
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 Boards D865PERC and
D865PESO 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
46
Product Description
1.13.2.4 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 Boards D865PERC and D865PESO 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 12 on page 44 lists the devices and events that can wake the computer
from the S3 state.
The Desktop Boards D865PERC and D865PESO support the PCI Bus Power Management
Interface Specification. For information on the version of this specification, see Section 1.5.
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.
1.13.2.5 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
1.13.2.6 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.
1.13.2.7 Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S1 or S3 state.
1.13.2.8 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).

2.1 Introduction
Sections 2.2 - 2.6 contain several standalone tables. Table 14 describes the system memory map,
Table 15 lists the DMA channels, Table 16 shows the I/O map, Table 17 defines the PCI
configuration space map, and Table 18 describes the interrupts. The remaining sections in this
chapter are introduced by text found with their respective section headings.
2.2 Memory Resources
2.2.1 Addressable Memory
The board utilizes 4 GB of addressable system memory. Typically the address space that is
allocated for PCI add-in cards, AGP aperture, BIOS (firmware hub), and chipset overhead resides
above the top of DRAM (total system memory). On a system that has 4 GB of system memory
installed, it is not possible to use all of the installed memory due to system address space being
allocated for other system critical functions. These functions include the following:
• Memory-mapped I/O that is dynamically allocated for PCI and AGP cards
• AGP aperture
• APIC and chipset overhead (approximately 18 MB)
• BIOS/firmware hub (approximately 2 MB)
The amount of installed memory that can be used will vary based on add-in cards and BIOS
settings. For example, if the PCI cards are requesting 200 MB of system memory and the AGP
aperture is set to 256 MB in the BIOS Setup program, there will be approximately 3.54 GB of
memory that can be accessed. Figure 17 shows a schematic of the system memory map. All
49
Intel Desktop Board D865PERC/D865PESO Technical Product Specification
installed system memory can be used when there is no overlap of system addresses. For example,
all of the system address space can be utilized on a system that has 2 GB of installed system
memory, AGP aperture set for 256 MB, and the PCI cards are requesting 200 MB of system
address space.

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 D865PERC and D865PESO
and therefore share the same interrupt. Table 19 shows an example of how the PIRQ signals are
routed.
For example, using Table 19 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 18 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 58)
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 59)

The board has the following expansion slots:
• AGP connector: 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 install a legacy 3.3 V AGP card. The AGP connector is not
mechanically compatible with legacy 3.3 V AGP cards.
• PCI rev 2.2 compliant local bus slots (six on the Desktop Board D865PERC, three on the
Desktop Board D865PESO). The SMBus is routed to PCI bus connector 2 only (ATX
expansion slot 6). PCI add-in cards with SMBus support can access sensor data and other
information residing on the Desktop Board.
NOTE
✏
This document references back-panel slot numbering with respect to processor location on the
board. The AGP slot is not numbered. PCI slots are identified as PCI slot #x, starting with the
slot closest to the processor. Figure 21 (page 65) and Figure 22 (page 66) illustrate the board’s
PCI slot numbering.

3.1 Introduction
The Desktop Boards D865PERC and D865PESO use 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 1.5, page 18
3.2 BIOS Flash Memory Organization
The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device.
85
Intel Desktop Board D865PERC/D865PESO 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 1.5, page 18
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 1.5 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.
86
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 1.5, page 18
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.
87
Intel Desktop Board D865PERC/D865PESO 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 1.3, page 17
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.
88
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 1.3, page 17
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

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 1.5, page 18
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
The BIOS Setup program’s Security menu Table 64, page 114
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 program’s Boot Device Priority
Submenu). Table 45 lists the boot device menu options.

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
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.
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 46 shows the effects of setting the supervisor password and user password. This table is for
reference only and is not displayed on the screen.
