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 ports (four ports routed to the back

panel and four ports routed to two onboard USB 2.0 headers). The 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.

Enhanced IDE Interface

The IDE interface handles the exchange of information between the processor and

peripheral devices such as hard disks and optical drives inside the computer. The

interface supports:

• Up to two IDE devices (such as hard drives)

• ATAPI-style devices (such as CD-ROM or DVD drives)

• Older PIO Mode devices

• Ultra DMA-33/66/100 modes

Serial ATA

The Desktop Board supports two Serial ATA channels (3.0 Gb/s), connecting one

device per channel.

Expandability

The Desktop Board supports one PCI add-in card.

Desktop Board Features

17

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.

IDE Auto Configuration

If you install an IDE device (such as a hard drive) in your computer, the 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.

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.

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.

For instructions on resetting the password, see Clearing Passwords on page 36.

Intel Desktop Board D945GCLF2 Product Guide

Power Management Features

Power management is implemented at several levels, including:

• Advanced Configuration and Power Interface (ACPI)

• Hardware support:

― Power connectors

― Fan headers

― +5 V standby power indicator LED

― LAN Wake capabilities

― 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.

Hardware Support

Power Connectors

The Desktop Board has two power connectors. See Figure 13 on page 34 for the

location of the power connectors.

Fan Headers

The Desktop Board has a 3-pin MCH fan header and a 3-pin chassis fan header. See

Figure 12 on page 33 for the location of the chassis fan header.

+5 V Standby Power Indicator LED

CAUTION

If the AC power has been switched off and the standby power indicator is still lit,

disconnect the power cord before installing or removing any devices connected to the

board. Failure to do so could damage the board and any attached devices.

The Desktop Board’s standby power indicator, shown in Figure 4, is lit when there is

standby power to the system. This includes the DIMM socket and the PCI bus

connector, even though the computer appears to be off.

Desktop Board Features

19

Figure 4. Location of the Standby Power Indicator

For more information on standby current requirements for the Desktop Board, refer to

the Technical Product Specification on the Intel Desktop D945GCLF2 web page at

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

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, 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.

LAN wakeup capabilities enable remote wake-up of the computer through a network.

The LAN subsystem monitors network traffic and upon detecting a Magic Packet*

frame, it asserts a wake-up signal that powers up the computer.

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 S3 state.

Intel Desktop Board D945GCLF2 Product Guide

20

Wake from PS/2 Keyboard/Mouse

PS/2 keyboard/mouse activity wakes the computer from the ACPI S1, S3, S4, and S5

states.

PME# Wakeup Support

When the PME# signal on the PCI bus is asserted, the computer wakes from the ACPI

S1, S3, S4, and S5 states.

Battery

A battery on the Desktop Board keeps the values in CMOS RAM and the clock current

when the computer is turned off. Go to page 37 for instructions on how to replace the

battery.

Real-Time Clock

The Desktop Board has a time-of-day clock and 100-year calendar. The battery on the

Desktop Board keeps the clock current when the computer is turned off.
