These Intel desktop boards support 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 Zip† drives 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

Accelerated Graphics Port (AGP)

NOTE

Desktop Boards D845GRG and D845GBV are 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.

Communication and Networking Riser (CNR) (Optional)

The optional CNR provides an interface that supports various features such as audio, modem, USB, and LAN.

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 37.

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.

Desktop Board Features

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 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 D845GRG or D845GBV requires an operating system that provides full ACPI support.

Intel Desktop Boards D845GRG and D845GBV Product Guide

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 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.

CR6H1

OM13591

Figure 3. Location of Standby Power Indicator

Desktop Board Features

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 these desktop boards, refer to the TPS by selecting the Technical Documentation link at:

Board Connectors

Intel desktop 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 headers

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.
