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 D945GCZ Technical Product Specification 1.13.1.3 Wake-up Devices and Events Table 9 lists the devices or specific events that can wake the computer from specific states. Table 9.
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. 1.13.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control.
Intel Desktop Board D945GCZ Technical Product Specification Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in the following ways: • The PCI Express WAKE# signal • The PCI Conventional bus PME# signal for PCI 2.3 compliant LAN designs • The onboard LAN subsystem 1.13.2.
Product Description 1.13.2.9 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. 1.13.2.10 +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 16 shows the location of the standby power indicator LED.

Intel Desktop Board D945GCZ Technical Product Specification 2.11 Electrical Considerations 2.11.1 DC Loading Table 31 lists the DC loading characteristics of the boards. 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 Fan Connector Current Capability CAUTION The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation. Table 32 lists the current capability of the fan connectors. Table 32. Fan Connector Current Capability Fan Connector Maximum Available Current Processor fan 3.0 A Front chassis fan 1.5 A Rear chassis fan 1.
Intel Desktop Board D945GCZ Technical Product Specification 2.12 Thermal Considerations CAUTION o A chassis with a maximum internal ambient temperature of 38 C at the processor fan inlet is a requirement. Use a processor heatsink that provides omni-directional airflow (similar to the type shown in Figure 28) to maintain required airflow across the processor voltage regulator area. OM16996 Figure 28.
Technical Reference CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area o (item A in Figure 29) can reach a temperature of up to 85 C in an open chassis. Figure 29 shows the locations of the localized high temperature zones.

Intel Desktop Board D945GCZ Technical Product Specification Table 38 lists the BIOS Setup program menu features. Table 38.
Overview of BIOS Features automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.
Intel Desktop Board D945GCZ Technical Product Specification 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used.
Overview of BIOS Features 3.7 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. 3.7.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification.
Intel Desktop Board D945GCZ Technical Product Specification 3.8 Adjusting Boot Speed These factors affect system boot speed: • Selecting and configuring peripherals properly • Optimized BIOS boot parameters 3.8.1 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.
Overview of BIOS Features 3.9 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 D945GCZ 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.
