Desktop Board Features
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI/PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 65.
Serial ATA Auto Configuration
If you install a Serial ATA 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. 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
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/PCI Express 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, go to Clearing Passwords on page 56.

Intel Desktop Board DP67BG Product Guide
Back to BIOS Button
The back panel Back to BIOS button (Figure 3, A) duplicates the functionality of the
BIOS configuration jumper (see Setting the BIOS Configuration Jumper on page 55)
wi
th the following exceptions:
• It can only be used to force the board to power on to the BIOS Maintenance Menu
using default values but it will retain all previously saved changes.
• It cannot be used to override passwords set in the BIOS.
• It cannot be used to invoke BIOS recovery mode.
The button glows red when it is activated.
NOTE
Using the Back to BIOS button does not set the board to the factory BIOS
defaults. To restore settings to the factory defaults, use the <F9> key once
BIOS setup mode is active.
Figure 3. Location of the Back to BIOS Button

ATX12V-compliant power supplies can turn off the computer power through system
control. When an ACPI-enabled computer receives the correct command, the power
supply removes all non-standby voltages.
When resuming from an AC power failure, the computer returns to the power state it
was in before power was interrupted (either on or off). The computer’s response can
be set by using the Last Power State feature in the BIOS Setup program’s Boot menu.
The Desktop Board has three power connectors. See Figure 27 on page 54 for the
location of the power co
nnectors

Fan Headers
The function/operation of the fans is as follows:
• The fans are on when the computer is in the ACPI S0 state.
• The fans are off when the computer is in the ACPI S3, S4, or S5 state.
• Each fan header is wired to a tachometer input of the hardware monitoring and
control device.
• All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed.
• All fan headers have a +12 V DC connection.
The Desktop Board has a 4-pin processor fan header and three 4-pin chassis fan
headers.
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.
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.
22
Desktop Board Features
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep state. While in the S3 sleep state, the computer will appear to be off. If
the computer has a dual-colored power LED on the front panel, the sleep state is
indicated by the LED turning amber. When signaled by a wake-up device or event, the
computer quickly returns to its last known awake state.
The Desktop Board supports the PCI Bus Power Management Interface Specification.
Add-in cards that support this specification can participate in power management and
can be used to wake the computer.
Wake from USB
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and an operating system that supports Wake from USB.
USB bus activity wakes the computer from an ACPI S1 or S3 state.
PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an
ACPI S1, S3, S4, or S5 state.
WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S1, S3, S4, or S5 state.
Wake from Consumer IR
Consumer IR device activity wakes the computer from an ACPI S3, S4, or S5 state.

Onboard Power and Reset Buttons
The lighted Power button on the Desktop Board (Figure 4, B) can be used to turn the
computer on or off. This button duplicates the function of the front panel power
button. To turn off the computer using the onboard Power button, press it for three
seconds.
The Power button stays lit when there is standby power still present on the board.
This is the case even when the computer appears to be off. For example, when this
button is lit, standby power is still present at the memory module sockets and the PCI
bus connectors.
CAUTION
If the AC power has been switched off and the onboard power button 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 lighted Reset button on the Desktop Board (Figure 4, A) can be used to reset the
board. This button duplicates the function of the front panel Reset button.
