• One AGP connector

Intel Desktop Board D845PEBT2 Product Guide

Accelerated Graphics Port (AGP)

NOTE

✏

Desktop Board D845PEBT2 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 51.

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

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.

Desktop Board Features

• 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 D845PEBT2 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 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.

Figure 2. Location of Standby Power Indicator

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.

For more information on standby current requirements for this desktop board, refer to the Technical Product Specification (TPS) by selecting the Technical Documentation link at:

Desktop Board Features

Power Connectors

Desktop Board D845PEBT2 has two power connectors. See Figure 13 on page 36 for the location of the power connectors.

Fan Connectors

Desktop Board D845PEBT2 has two chassis fan connectors (Intel Precision Cooling Technology) and one processor fan connector. See Figure 13 on page 36 for the location of the fan connectors.

Fan Speed Control (Intel® Precision Cooling Technology)

Intel Precision Cooling Technology 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 (J8H3 and J1B1). The processor fan connector (J1F1) 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.
