Intel Desktop Board D925XHY Technical Product Specification 1.11.1 ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the board requires an operating system that provides full ACPI support.
Product Description 1.11.1.1 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 D925XHY Technical Product Specification 2.10 Mechanical Considerations 2.10.1 Form Factor The Desktop Board D925XHY is designed to fit into an ATX-form-factor chassis. Figure 21 illustrates the mechanical form factor of the board. Dimensions are given in inches [millimeters]. The outer dimensions are 12.00 inches by 9.60 inches [304.80 millimeters by 243.84 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification. 1.800 [45.72] 6.
Technical Reference 2.10.2 I/O Shield The back panel I/O shield for the board must meet specific dimension and material requirements. Systems based on this board need the back panel I/O shield to pass certification testing. Figure 22 shows the I/O shield. Dimensions are given in inches to a tolerance of ±0.02 inches. The figures also indicate the position of each cutout. Additional design considerations for I/O shields relative to chassis requirements are described in the ATX specification.
Intel Desktop Board D925XHY Technical Product Specification 2.11 Electrical Considerations 2.11.1 DC Loading Table 29 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 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 30 lists the current capability of the fan connectors. Table 30.
Intel Desktop Board D925XHY 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 heatsink that provides omni-directional airflow (as shown in Figure 23) to maintain required airflow across the processor voltage regulator area. OM16996 Figure 23.
Technical Reference CAUTION Ensure that the ambient temperature does not exceed the board’s maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.14. 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.
Intel Desktop Board D925XHY Technical Product Specification Table 31 provides maximum case temperatures for the board 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 31.
Technical Reference 2.14 Environmental Table 32 lists the environmental specifications for the board. Table 32.

Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed. Memory Size Decreased Memory size has decreased since the last boot. If no memory was removed then memory may be bad. Memory Size Increased Memory size has increased since the last boot.
Error Messages and Beep Codes 4.2 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. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
