Product Description 1.12 Power Management Power management is implemented at several levels, including: • • 1.12.
Intel Desktop Board D945GPM Technical Product Specification 1.12.1.1 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.
Product Description 1.12.1.3 Wake-up Devices and Events Table 9 lists the devices or specific events that can wake the computer from specific states. Table 9.
Intel Desktop Board D945GPM Technical Product Specification 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. 1.12.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control.
Product Description 1.12.2.3 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. The LAN network adapter monitors network traffic at the Media Independent Interface.
Intel Desktop Board D945GPM Technical Product Specification • • • ⎯ Power continues to the vital components on the system (CPU, memory, and fans, for example). The Intel QRTD off state allows tasks that do not require user input to continue in the background. Works with the Microsoft Away mode to offer a complete power management offering for ACPI and system standby and hibernate. Target resume time is zero to five seconds (about equal to the time it takes for the display to warm up).
Product Description 1.12.2.11 +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 14 shows the location of the standby power indicator LED. CAUTION If 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.

Intel Desktop Board D945GPM Technical Product Specification 2.10 Electrical Considerations 2.10.1 DC Loading Table 30 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 2.10.3 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 31 lists the current capability of the fan connectors. Table 31. 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 D945GPM Technical Product Specification 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 (similar to the type shown in Figure 25) to maintain required airflow across the processor voltage regulator area. OM16996 Figure 25.
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 (item A in Figure 26) can reach a temperature of up to 85 oC in an open chassis. Figure 26 shows the locations of the localized high temperature zones.
Intel Desktop Board D945GPM Technical Product Specification Table 32 provides maximum case temperatures for the components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board. Table 32.

Intel Desktop Board D945GPM 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 D945GPM 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 D945GPM Technical Product Specification 3.8 Adjusting Boot Speed These factors affect system boot speed: • • 3.8.1 Selecting and configuring peripherals properly Optimized BIOS boot parameters Peripheral Selection and Configuration The following techniques help improve system boot speed: • • • • 3.8.2 Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays.
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 D945GPM 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.
