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.
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.

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.
16
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 auto-
configuration options by specifying manual configuration in the BIOS Setup program.

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.
17
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.

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.

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.
