Product Description 1.10.1.1 System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.
Intel Desktop Board DG965OT Technical Product Specification 1.10.1.2 Two-Watt Standby In 2001, the U.S. government issued an executive order requiring a reduction in power for appliances and personal computers. This board meets that requirement by operating at 1.5 W (or less) in S5 (Standby) mode. Two-Watt operation applies only to the S5 state when the computer is turned off, but still connected to AC power. Two-Watt operation does not apply to the S3 (Suspend to RAM) or S4 (Suspend to disk) states.
Product Description • • • • • • • • LAN wake capabilities Instantly Available PC technology Resume on Ring Wake from USB Wake from PS/2 keyboard PME# signal wake-up support WAKE# signal wake-up support Intel Quick Resume Technology Drivers (Intel QRTD) LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. Resume on Ring enables telephony devices to access the computer when it is in a power-managed state.
Intel Desktop Board DG965OT Technical Product Specification 1.10.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line from the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network.
Product Description 1.10.2.5 Intel® Quick Resume Technology Drivers (Intel® QRTD) The Intel Quick Resume Technology Drivers (Intel QRTD) manage the on and off functions for Intel® Viiv™ platforms and have the following features: • • • Instantly turns the Intel Viiv platform off by pressing the power button on the PC or remote control. Instantly turns the Intel Viiv platform on by moving the mouse, pressing a key on the keyboard, or pressing the on/off button on the remote control or computer.
Intel Desktop Board DG965OT Technical Product Specification 1.10.2.10 WAKE# Signal Wake-up Support When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state. 1.10.2.11 +5 V Standby Power Indicator LED The +5 V standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 13 shows the location of the standby power indicator LED.

Intel Desktop Board DG965OT Technical Product Specification 2.11 Electrical Considerations 2.11.1 DC Loading Table 32 lists the DC loading characteristics of the board. This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw.
Technical Reference 2.11.3 Add-in Board Considerations The board is designed to provide 2 A (average) of +5 V current for each add-in board. The total +5 V current draw for add-in boards for a fully loaded board (all three expansion slots and the PCI Express x16 connector filled) must not exceed 8 A. 2.11.4 Power Supply Considerations CAUTION The +5 V standby line from the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply.
Intel Desktop Board DG965OT Technical Product Specification 2.12 Thermal Considerations CAUTION A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Use a processor heat sink that provides omni-directional airflow to maintain required airflow across the processor voltage regulator area.

Intel Desktop Board DG965OT Technical Product Specification Table 36 lists the BIOS Setup program menu features. Table 36.
Overview of BIOS Features 3.3.2 PCI IDE Support If you select Auto in the BIOS Setup program, the BIOS automatically sets up the PCI IDE connector with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100/133 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance.
Intel Desktop Board DG965OT Technical Product Specification 3.5 Legacy USB Support Legacy USB support enables USB devices to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3.
Overview of BIOS Features 3.6.1 Language Support The BIOS Setup program and help messages are supported in US English. Additional languages are available in the Integrator’s Toolkit utility. Check the Intel website for details. 3.6.2 Custom Splash Screen During POST, an Intel® splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Integrator’s Toolkit that is available from Intel can be used to create a custom splash screen.
Intel Desktop Board DG965OT Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, a USB drive, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. If enabled, the last default boot device is the network. 3.8.
Overview of BIOS Features 3.9 Adjusting Boot Speed These factors affect system boot speed: • • Selecting and configuring peripherals properly Optimized BIOS boot parameters 3.9.1 Peripheral Selection and Configuration The following techniques help improve system boot speed: • • • • Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays. Select a CD-ROM drive with a fast initialization rate.
Intel Desktop Board DG965OT Technical Product Specification 3.10 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: • • • • • • • The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode.

Intel Desktop Board DG965OT Technical Product Specification 4.4 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card.
