The outer dimensions are 9.60 inches by 8.50 inches [243.84 millimeters by 215.90 millimeters].
Technical Reference 2.10.1 I/O Shield The back panel I/O shield for the Desktop Board D865GVHZ must meet specific dimension and material requirements. Systems based on this Desktop Board need the back panel I/O shield to pass certification testing. Figure 23 shows the I/O shield. Dimensions are given in inches to a tolerance of ±0.02 inches. The figure also indicates the position of each cutout.
Intel Desktop Board D865GVHZ Technical Product Specification 2.11 Electrical Considerations 2.11.1 DC Loading Table 43 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 2.11.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. System integrators should refer to the power usage values listed in Table 43 when selecting a power supply for use with the board.
Intel Desktop Board D865GVHZ Technical Product Specification CAUTION Ensure that the ambient temperature does not exceed the Desktop 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.
Technical Reference Table 45 provides maximum case temperatures for the Desktop Board D865GVHZ 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 Desktop Board D865GVHZ. Table 45.
Intel Desktop Board D865GVHZ Technical Product Specification 2.13 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using component and subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBF prediction is used to estimate repair rates and spare parts requirements. The MTBF data is calculated from predicted data at 55 ºC. The Desktop Board D865GVHZ MTBF is 149979.68 hours. 2.

Intel Desktop Board D865GVHZ Technical Product Specification Table 80. BIOS Error Messages (continued) Error Message Explanation Checking NVRAM..... NVRAM is being checked to see if it is valid. Update OK! NVRAM was invalid and has been updated. Updated Failed NVRAM was invalid but was unable to be updated. Keyboard Error Error in the keyboard connection. Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed.
Error Messages and Beep Codes 5.2 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.
