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 D946GZAB Technical Product Specification 1.10.1.3 Wake-up Devices and Events Table 8 lists the devices or specific events that can wake the computer from specific states. Table 8.
Product Description Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal). NOTE The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support. 1.10.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control.
Intel Desktop Board D946GZAB Technical Product Specification 1.10.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for 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 1.10.2.6 Wake from USB USB bus activity wakes the computer from ACPI S1 or S3 states. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. 1.10.2.7 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1 or S3 state. 1.10.2.8 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 (with Wake on PME enabled in BIOS). 1.10.2.

Additional design considerations for I/O shields relative to chassis requirements are described in the ATX specification.
Technical Reference 2.10 Electrical Considerations 2.10.1 DC Loading Table 28 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.
Intel Desktop Board D946GZAB Technical Product Specification 2.10.3 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. 2.10.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current.
Technical Reference 2.11 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 heatsink that provides omni-directional airflow to maintain required airflow across the processor voltage regulator area. CAUTION Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board.

Intel Desktop Board D946GZAB Technical Product Specification Table 32 lists the BIOS Setup program menu features. Table 32.
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 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 D946GZAB 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 D946GZAB Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, 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. The fourth device is disabled. 3.8.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification.
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 D946GZAB 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.
