The BIOS is stored in the Serial Peripheral Interface (SPI) Flash.<br><br> The BIOS can be updated by following the instructions on page 65 in Chapter 3. Serial ATA and IDE Auto Configuration If you install a Serial ATA or 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 a Serial ATA or IDE device.<br><br> 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.<br><br> Intel Desktop Board DG33TL Product Guide 20 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.<br><br> " 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.<br><br> 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.<br><br> Related Links: For instructions on resetting the password, see Clearing Passwords on page 58. Hardware Management Features The hardware management features of Desktop Board DG33TL enable the board to be compatible with the Wired for Management (WfM) specification.

Power Management Features Power management is implemented at several levels, including: " Software support through the Advanced Configuration and Power Interface (ACPI) " Hardware support: ¯ Power connectors ¯ Fan headers ¯ LAN wake capabilities ¯ Instantly Available PC technology (Suspend to RAM) ¯ +5 V standby power indicator LED ¯ Wake from USB ¯ Power Management Event signal (PME#) wakeup support ¯ WAKE# signal wake-up support " ENERGY STAR capable ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer.<br><br> The use of ACPI with the Desktop Board requires an operating system that provides full ACPI support. Intel Desktop Board DG33TL Product Guide 22 Hardware Support Power Connectors 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.<br><br> 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 9s response can be set by using the Last Power State feature in the BIOS Setup program 9s Boot menu. The Desktop Board has two power connectors.<br><br> See Figure 26 on page 55 for the location of the power connectors. 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.<br><br> " 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.<br><br> The Desktop Board has a 4-pin processor fan header, and one 4-pin and two 3-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.<br><br> 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. Desktop Board Features 23 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.<br><br> 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.<br><br> 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. If the computer has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.<br><br> 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.<br><br> Intel Desktop Board DG33TL Product Guide 24 +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 9s standby power indicator, shown in Figure 3, is lit when there is standby power still present on the board even when the computer appears to be off.<br><br> For example, when this LED is lit, standby power is still present at the memory module sockets and the PCI bus connectors. Figure 3. Location of the Standby Power Indicator Related Links: For more information on standby current requirements for the Desktop Board, refer to the Technical 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.<br><br> USB bus activity wakes the computer from an ACPI S3 state. Desktop Board Features 25 PME# Signal Wake-up Support When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI 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 S2, S3, S4, or S5 state.<br><br> ENERGY STAR* Capable In 2007, the US Department of Energy and the US Environmental Protection Agency revised the ENERGY STAR requirements. Intel worked directly with these two governmental agencies to define the new requirements. Currently Intel Desktop Boards are capable of meeting the new ENERGY STAR requirements depending upon system configuration.<br><br> Go to the following link for information and recommendations concerning the the new ENERGY STAR requirements: http://www.intel.com/go/EnergyStar Speaker A speaker is mounted on the Desktop Board.
