Hi-Speed USB 2.0 Support  
NOTE  
Computer systems that have an unshielded cable attached to a USB port might not meet FCC  
Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a  
shielded cable that meets the requirements for a full-speed USB device.  
This Intel desktop board supports up to six USB 2.0 ports via ICH4; four ports routed to the back  
panel and two routed to a USB front panel header. USB 2.0 ports are backward compatible with  
USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.  
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer  
rates. Disabling Hi-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may  
be required to accommodate operating systems that do not support USB 2.0.  
NOTE  
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver  
initialization.  
Enhanced IDE Interface  
The ICH4’s IDE interface handles the exchange of information between the processor and  
peripheral devices like hard disks, CD-ROM drives, and Iomega Zipdrives inside the computer.  
The interface supports:  
Up to four IDE devices (such as hard drives)  
ATAPI devices (such as CD-ROM drives)  
Older PIO Mode devices  
Ultra DMA-33 and ATA-66/100 protocols  
Laser servo (LS-120) drives

Desktop Board Features  
Expansion Slots  
Desktop Board D845PESV has the following add-in card connectors:  
Six PCI bus add-in card connectors (SMBus routed to PCI bus connector 2)  
One AGP connector  
Accelerated Graphics Port (AGP)  
NOTE  
Desktop Board D845PESV is only compatible with 1.5 V AGP cards.  
AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics.  
AGP is independent of the PCI bus and is intended for exclusive use with graphical  
display devices.  
The AGP connector supports 1.5 V AGP 4X and 2X add-in cards.  
BIOS  
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE  
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.  
The BIOS can be updated by following the instructions in Chapter 3 on page 39.  
PCI Auto Configuration  
If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS  
automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that  
add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card.  
IDE Auto Configuration  
If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration  
utility in the BIOS automatically detects and configures the device for your computer. You do not  
need to run the BIOS Setup program after installing an IDE device. 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  
15  
Intel Desktop Board D845PESV Product Guide  
Security Passwords  
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed  
and who can boot the computer. A supervisor password and a user password can be set for the  
Setup and for booting the computer, with the following restrictions:  
The supervisor password gives unrestricted access to view and change all Setup options. If  
only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives  
the user restricted access to Setup.  
If both the supervisor and user passwords are set, you must enter either the supervisor  
password or the user password to access Setup. Setup options are then available for viewing  
and changing depending on whether the supervisor or user password was entered.  
Setting a user password restricts who can boot the computer. The password prompt is  
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, you can enter either password  
to boot the computer.  
Power Management Features  
Power management is implemented at several levels, including:  
Advanced Configuration and Power Interface (ACPI)  
Suspend to RAM (Instantly Available PC technology)  
ACPI  
ACPI gives the operating system direct control over the power management and Plug & Play  
functions of a computer. The use of ACPI with Desktop Board D845PESV requires an operating  
system that provides full ACPI support.  
Suspend to RAM (Instantly Available PC Technology)  
CAUTION  
For Instantly Available PC technology, the 5 V standby line for the power supply must be capable  
of delivering adequate +5 V standby current. Failure to provide adequate standby current when  
using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.  
Instantly Available technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep  
state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up  
device or event, the system quickly returns to its last known awake state.  
The Intel desktop board’s standby power indicator, shown in Figure 2, is lit when there is standby  
power to the system. This includes the memory modules and PCI bus connectors, even when the  
computer appears to be off.  
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the  
LED turning amber.

CAUTION  
Power supplies used with this board must be able to provide enough standby current to support the  
standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary  
to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity,  
the Intel desktop board may lose register settings stored in memory.

®
Fan Speed Control (Intel Precision Cooling)  
Intel Precision Cooling automatically adjusts the chassis fan speeds depending on the system’s  
temperature. This feature reduces system fan noise by lowering the speed of the chassis fans  
connected to the front and rear chassis fan connectors (J9H3 and J6B2). The processor fan  
connector (J2F1) is not controlled.  
The fan speed control feature can be disabled in the BIOS, resulting in the chassis fans always  
operating at full speed. This feature should be disabled if a self-controlled fan is attached to a  
chassis fan connector.  
Overall system noise reduction will vary based on system configuration and environment.  
Resume on Ring  
The operation of Resume on Ring can be summarized as follows:  
Resumes operation from either ACPI S1 or ACPI S3 state  
Requires only one call to access the computer  
Detects incoming call similarly for external and internal modems  
Requires modem interrupt be unmasked for correct operation  
Wake from USB  
USB bus activity wakes the computer from an ACPI S1 or S3 state.  
NOTE  
Wake from USB requires the use of a USB peripheral that supports Wake from USB.  
Wake from PS/2 Keyboard/Mouse  
PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 or S3 state.  
PME# Wakeup Support  
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, or  
S5 state.  
Speaker  
A speaker is mounted on the desktop board. The speaker provides audible error code (beep code)  
information during the Power-On Self-Test (POST).

bootable flash memory update floppy that will automatically update your BIOS.  
Obtaining the BIOS Update File  
You can update to a new version of the BIOS by using the BIOS update file. The BIOS update file  
is a compressed self-extracting archive that contains all the files you need to update the BIOS. The  
BIOS update file contains:  
New BIOS files  
BIOS recovery files  
Intel Flash Memory Update Utility  
You can obtain the BIOS update file through your computer supplier or by navigating to the  
Desktop Board D845PESV page on the Intel World Wide Web site:  
NOTE  
Please review the instructions distributed with the update utility before attempting a BIOS update.  
The Intel Flash Memory Update Utility allows you to:  
Update the BIOS in flash memory  
Update the language section of the BIOS  
Updating the BIOS  
CAUTION  
The AUTOEXEC.BAT file provided with the update files updates the BIOS. Do not interrupt the  
process or the system may not function.  
1. Boot the computer with the BIOS update diskette in drive A. During system boot, the  
AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update  
process.  
2. When the update process is complete, the monitor will display a message telling you to remove  
the diskette and to reboot the system.  
3. As the computer boots, check the BIOS identifier (version number) to make sure the update  
was successful. If a logo appears, press <Esc> to view the POST messages.

Updating the BIOS  
Recovering the BIOS  
It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the  
BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails.  
The following procedure uses recovery mode for the Setup program. See page 34 for more  
information on Setup modes.  
NOTE  
Because of the small amount of code available in the boot block area, there is no video support.  
You will not see anything on the screen during this procedure. Monitor the procedure by listening  
to the speaker and looking at the diskette drive LED.  
1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external  
peripherals.  
2. Remove the computer cover and locate the configuration jumper block (see Figure 12).  
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.  
3
1
4. Insert the bootable BIOS update diskette into diskette drive A.  
5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to  
boot. The recovery process will take a few minutes.  
6. Listen to the speaker:  
Upon applying power, drive A will begin to show activity. In about a minute, two beeps  
are heard and drive A activity ceases (temporarily) indicating the successful recovery of  
the BIOS core. Drive A activity will begin again followed by two more beeps indicating  
the successful recovery of the boot block. This sequence of events indicates a successful  
BIOS recovery.  
A series of continuous beeps indicates a failed BIOS recovery.  
7. If recovery fails, return to step 1 and repeat the recovery process.  
8. If recovery is successful, turn off the computer, and disconnect its power cord.  
9. Remove the computer cover and continue with the following steps.  
10. On the jumper block, reinstall the jumper back on pins 1-2 as shown below to set normal mode  
for Setup.

11. Leave the update diskette in drive A, replace the computer cover, and connect the computer’s  
power cord.  
12. Turn on the computer and continue with the BIOS update.

4 Using the BIOS Setup Program  
The BIOS Setup program can be used to view and change the BIOS settings for the computer. The  
BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST)  
memory test begins and before the operating system boot begins.  
NOTE  
The BIOS Setup menus described in this section may not show the latest settings. For the latest  
BIOS settings, refer to the Intel® Desktop Board D845PESV Technical Product Specification or  
the Intel World Wide Web site:  
NOTE  
For reference purposes, you should write down the current Setup settings. When you make  
changes to the settings, update this record.  
NOTE  
The Setup menus described in this section apply to the desktop boards with BIOS identifier  
SV84510A.86A. Boards with other BIOS identifiers might have differences in some of the  
Setup menu screens.

instructions.  
To avoid injury, be careful of:  
Sharp pins on connectors  
Sharp pins on printed circuit assemblies  
Rough edges and sharp corners on the chassis  
Hot components (like processors, voltage regulators, and heat sinks)  
Damage to wires that could cause a short circuit  
Observe all warnings and cautions that instruct you to refer computer servicing to qualified  
technical personnel.  
Installation Instructions  
CAUTION  
Follow these guidelines to meet safety and regulatory requirements when installing this board  
assembly.  
Read and adhere to all of these instructions and the instructions supplied with the chassis and  
associated modules. If the instructions for the chassis are inconsistent with these instructions or  
the instructions for associated modules, contact the supplier’s technical support to find out how  
you can ensure that your computer meets safety and regulatory requirements. If you do not follow  
these instructions and the instructions provided by chassis and module suppliers, you increase  
safety risk and the possibility of noncompliance with regional laws and regulations.  
Ensure Electromagnetic Compatibility (EMC) Compliance  
Before computer integration, make sure that the power supply and other modules or peripherals, as  
applicable, have passed Class B EMC testing and are marked accordingly.  
In the installation instructions for the host chassis, power supply, and other modules pay close  
attention to the following:  
Product certifications or lack of certifications  
External I/O cable shielding and filtering  
Mounting, grounding, and bonding requirements  
Keying connectors when mating the wrong connectors could be hazardous  
If the power supply and other modules or peripherals, as applicable, are not Class B EMC  
compliant before integration, then EMC testing is required on a representative sample of the newly  
completed computer.  
77  
Intel Desktop Board D845PESV Product Guide  
Chassis and Component Certifications  
Ensure that the chassis and certain components; such as the power supply, peripheral drives,  
wiring, and cables; are components certified for the country or market where used. Agency  
certification marks on the product are proof of certification. Typical product certifications include:  
In Europe  
The CE marking signifies compliance with all applicable European requirements. If the chassis  
and other components are not properly CE marked, a supplier’s Declaration of Conformity  
statement to the European EMC directive and Low Voltage directive (as applicable), should be  
obtained. Additionally, other directives, such as the Radio and Telecommunications Terminal  
Equipment (R&TTE) directive may also apply depending on product features.  
In the United States  
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL, CSA, or  
ETL signifies compliance with safety requirements. Wiring and cables must also be UL listed or  
recognized and suitable for the intended use. The FCC Class B logo for home or office use  
signifies compliance with electromagnetic interference (EMI) requirements.  
In Canada  
A nationally recognized certification mark such as CSA or cUL signifies compliance with safety  
requirements. The Industry Canada statement at the front of this product guide demonstrates  
compliance with Canadian EMC regulations. Industry Canada recognizes and accepts FCC  
certification as denoting compliance with national electromagnetic interference (emissions)  
requirements.  
Prevent Power Supply Overload  
Do not overload the power supply output. To avoid overloading the power supply, make sure that  
the calculated total current loads of all the modules within the computer is less than the output  
current rating of each of the power supplies output circuits.  
Place Battery Marking  
There is insufficient space on this desktop board to provide instructions for replacing and  
disposing of the Lithium ion coin cell battery. For system safety certification, the following  
statement or equivalent statement is required to be permanently and legibly marked on the chassis  
near the battery.  
CAUTION  
Risk of explosion if battery is incorrectly replaced.  
Replace with only the same or equivalent type recommended by the manufacturer. Dispose of used  
batteries according to the manufacturer’s instructions.  
Use Only for Intended Applications  
All Intel desktop processor boards are evaluated as Information Technology Equipment (I.T.E.) for  
use in personal computers for installation in homes, offices, schools, computer rooms, and similar  
locations. The suitability of this product for other applications or environments, such as medical,
