Intel Desktop Board D845GLVA Product Guide

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 desktop board supports up to four USB 2.0 ports via ICH4; two 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 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

drives inside the computer.

Expansion Slots

Desktop Board D845GLVA has three PCI bus add-in card connectors.

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 31.

Desktop Board Features

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.

• 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

• 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 the desktop board requires an operating system that provides full ACPI support.

Intel Desktop Board D845GLVA 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 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 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.

OM15860

Figure 2. Location of the 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 desktop board may lose register settings stored in memory.

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

http://developer.intel.com/design/motherbd/

WARNINGS

The procedures in this chapter assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment.

Disconnect the computer from its power source and from any telecommunications links, networks, or modems before performing any of the procedures described in this chapter. Failure to disconnect power, telecommunications links, networks, or modems before you open the computer or perform any procedures can result in personal injury or equipment damage. Some circuitry on the board can continue to operate even though the front panel power button is off.

CAUTION

Before you install this board in a chassis, see Appendix B for regulatory requirements and precautions.

• Always follow the steps in each procedure in the correct order.

• Set up a log to record information about your computer, such as model, serial numbers,

installed options, and configuration information.

• Electrostatic discharge (ESD) can damage components. Perform the procedures described in

this chapter only at an ESD workstation using an antistatic wrist strap and a conductive foam

pad. If such a station is not available, you can provide some ESD protection by wearing an

antistatic wrist strap and attaching it to a metal part of the computer chassis.

Installing the I/O Shield

The desktop board comes with an I/O shield. When installed in the chassis, the shield blocks radio frequency transmissions, protects internal components from dust and foreign objects, and promotes correct airflow within the chassis.

Install the I/O shield before installing the desktop board in the chassis. Place the shield inside the chassis as shown in Figure 3. Press the shield into place so that it fits tightly and securely. If the shield doesn’t fit, obtain a properly-sized shield from the chassis supplier.

Installing and Removing a Processor

Instructions on how to install the processor to the desktop board are given below.

Installing a Processor

CAUTION

Before installing or removing the processor, make sure that AC power has been removed by unplugging the power cord from the computer; the standby power LED should not be lit (see Figure 2 on page 16). Failure to do so could damage the processor and the desktop board.

To install a processor, follow these instructions:

1. Observe the precautions in “Before You Begin” on page 19.

2. Locate the processor socket and raise the socket lever completely.

3. Install the processor so that the corner with the triangle marking (A) is aligned with the corner where the lever is attached to the socket (see Figure 5).

4. Lower the lever to its original position.
