On (steady state) 100 Mbits/s data rate is selected

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.

The desktop board supports up to eight USB 2.0; four ports routed to the back panel and four routed
to two internal USB 2.0 headers. 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 the 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.

16

Desktop Board Features

Enhanced IDE Interface

The 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-style devices (such as CD-ROM drives)

• Older PIO Mode devices

• Ultra DMA-33/66/100 modes

Serial ATA

The desktop board supports four Serial ATA channels (1.5 Gb/s), connecting one device per
channel.

Expandability

The desktop board supports the following:

• One PCI Express x16 add-in card

• One PCI Express x1 add-in card

• Two PCI add-in cards

Related Links:

For information about installing the PCI Express x16 card, see page

34 in Chapter 2.

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI
Express and IDE auto-configuration utilities, and the video BIOS.

Serial ATA and IDE Auto Configuration

If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the auto­configuration 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 a Serial ATA or IDE device. You
can override the auto-configuration options by specifying manual configuration in the BIOS Setup
program.

PCI and PCI Express* Auto Configuration

If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express auto­configuration 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 or PCI Express add-in card.

17

Intel Desktop Board D102GGC2 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
BIOS 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.

Related Links:

For instructions on resetting the password, see

Clearing Passwords on page 46.

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed.
The security feature uses a mechanical switch on the chassis that can be connected to the chassis
intrusion connector on the desktop board. See
intrusion connector.

Figure 23 on page 44 for the location of the chassis

Power Management Features

Power management is implemented at several levels, including:

• Advanced Configuration and Power Interface (ACPI)

• Hardware support:

⎯ Power connectors

⎯ Fan connectors

⎯ Suspend to RAM (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 and Play
functions of a computer. The use of ACPI with the desktop board requires an operating system that
provides full ACPI support.

Power Connectors

The desktop board has two power connectors. See Figure 22 on page 43 for the location of the
power connectors.

18

Desktop Board Features

Fan Connectors

The desktop board has a 4-pin processor fan header and two 3-pin chassis fan headers. See
Figure 21 on page 42 for the location of the chassis fan headers.

Suspend to RAM (Instantly Available PC Technology)

CAUTIONS

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.

Power supplies used with this desktop 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.

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.

19

Intel Desktop Board D102GGC2 Product Guide

The 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.

Product Specification by going to the following link, finding the product, and selecting Product
Documentation from the left-hand menu:

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

Wake from USB

NOTE

Wake from USB requires the use of a USB peripheral that supports wake from USB.

USB bus activity wakes the computer from an ACPI S1 or S3 state.
