http://support.intel.com/support/motherboards/desktop/

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 43.

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.

Intel Desktop Boards D845PT and D845BG Product Guide

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 autoconfiguration 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

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

Speaker

A 47 Ω inductive speaker is mounted on the desktop board. The speaker provides audible error code (beep code) information during the Power-On Self-Test (POST).

Battery

A battery on the board keeps the values in CMOS RAM and the clock current when the computer is turned off. See Chapter 2 starting on page 23 for instructions on how to replace the battery.

Power Management Features

• Advanced Configuration and Power Interface (ACPI)

• Hardware:  Power connectors  Fan connectors  Resume on Ring  Instantly Available PC technology  Wake from USB  Wake from PS/2 keyboard/mouse  PME# wakeup support

ACPI

ACPI gives the operating system direct control over the power management and Plug & Play functions of a computer. The use of ACPI with the D845PT or D845BG board requires an operating system that provides full ACPI support.

Intel Desktop Boards D845PT and D845BG Product Guide

Hardware

Power Connectors

The D845PT and D845BG boards have two power connectors. See Figure 22 on page 70 for the location of the power connectors.

Fan Connectors

The D845PT and D845BG boards have one processor fan connector and two standard fan connectors. See Figure 22 on page 70 for the location of the fan connectors.

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from the ACPI S1 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

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 PC 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 board’s standby power indicator, shown in Figure 3, 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.

Desktop Board Features

OM12625

Figure 3. Location of Standby Power Indicator

CAUTION

If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory.

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 as outlined in Table 4. Values are determined by specifications such as PCI 2.2. Actual measurements may vary.

To estimate the total amount of standby current required for a particular system configuration, standby current requirements of all installed components must be added. Refer to the descriptions in and follow the steps outlined below:

1. Note the total D845PT or D845BG board standby current requirement.

2. Add to that the total PS/2 port standby current requirement if a wake-enabled device is connected.

3. Add, from the PCI 2.2 slots (wake-enabled) row, the total of the number of wake-enabled devices installed (PCI and AGP) multiplied by the standby current requirement.

4. Add, from the PCI 2.2 slots (non-wake-enabled) row, the total of the number of non-wakeenabled devices installed (PCI and AGP) multiplied by the standby current requirement.

5. Add all additional wake-enabled devices’ and non-wake-enabled devices’ standby current requirements as applicable.

6. Add all the required current totals from steps 1 through 5 to determine the total estimated standby current power supply requirement.

• Upon applying power, drive A will begin to show activity. In about a minute, two beeps

will be heard and drive A activity will cease (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 (J6F2), reinstall the jumper back on pins 1-2 as shown below to set normal mode for Setup.

2. Press <Enter> to set the selection as the intended boot device.

The operating system assigns a drive letter to each boot device in the order listed. Changing the order of the devices changes the drive lettering. The default settings for the first through final boot devices are, respectively listed below. The BIOS supports up to sixteen total boot devices in any combination of the boot device types below, with respect to these maximums per type.

• Removable Device (maximum of four)

• Hard Drive (maximum of 12)

• ATAPI CD-ROM (maximum of four)

• Intel UNDI, PXE (maximum of five)

The boot devices appear in order by type. For example, assume that the default boot order is preserved and that seven boot devices of the following types are installed on the system: two removable devices, two hard drives, two ATAPI CD-ROMs, and an Intel UNDI (Universal Network Device Interface), PXE device. Both removable devices would appear as the first and second boot devices, the two hard drives would appear as the third and fourth, the two ATAPI CD-ROM drives would appear as the fifth and sixth, and the Intel UNDI, PXE device would appear as the seventh boot device.

Board Connectors

The board connectors can be divided into three groups:

• Back panel connectors

• Midboard connectors  Audio connectors  Power and hardware connectors  Add-in board and peripheral interface connectors

• Front panel connectors

CAUTION

Many of the midboard and front panel connectors provide operating voltage (+5 V dc and +12 V dc, for example) to devices inside the computer chassis, such as fans and internal peripherals. These connectors are not overcurrent protected. Do not use these connectors for powering devices external to the computer chassis. A fault in the load presented by the external devices could cause damage to the computer, the interconnecting cable, and the external devices themselves.

Intel Desktop Boards D845PT and D845BG Product Guide

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.

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.

Regulatory Compliance

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, industrial, alarm systems, test equipment, etc. may require further evaluation.
