Intel Desktop Board D915PGN/D915PSY 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. 1.13.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control.
Product Description 1.13.2.3 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 D915PGN/D915PSY Technical Product Specification 1.13.2.6 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. 1.13.2.7 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1 or S3 state. 1.13.2.

Intel Desktop Board D915PGN/D915PSY Technical Product Specification 1.14 Trusted Platform Module (Optional) The optional Trusted Platform Module (TPM) is a component on the desktop board that is specifically designed to enhance platform security above-and-beyond the capabilities of today’s software by providing a protected space for key operations and other security critical tasks.
Product Description 1.14.3 Security Precautions Security, like any other aspect of computer maintenance requires planning. What is unique about security has to do with understanding who "friends" and adversaries are. The TPM provides mechanisms to enable the owner/user to protect their information from adversaries. To provide this protection the TPM effectively puts "locks" around the data. Just like physical locks, if keys or combinations are lost, the assets (i.e.
Intel Desktop Board D915PGN/D915PSY Technical Product Specification 1.14.3.2 Emergency Recovery File Back Up Procedures The Emergency Recovery Token (SPEmRecToken.xml) must be saved or moved to a removable media (floppy, USB drive, CDR, flash media, etc). Once this is done, the removable media should be stored in a secure location. DO NOT LEAVE ANY COPIES of the Emergency Recovery Token on the hard drive or within any hard drive image backups.
Product Description 1.14.5 Enabling the Trusted Platform Module The Trusted Platform Module is disabled by default when shipped to insure that the owner/end customer of the system initializes the TPM and configures all security passwords. The owner/end customer should use the following steps to enable the TPM. 1. While the PC is displaying the splash screen (or POST screen), press the key to enter BIOS. 2.
Intel Desktop Board D915PGN/D915PSY Technical Product Specification 15. Follow the instructions and create and document the locations for both the archive and restoration key files. The key archive should be located on a removable media and stored in a secure location when not in use. 16. Create and document the password to protect the key archive. 17. Provide the TPM Owner password to allow the Key Transfer Manager to create the archive and restoration key files. 18.
Product Description 4. Follow the instructions during the Security Platform Initialization, and append the Emergency Recovery Archive to the existing archive. 5. Provide all the necessary passwords, files, and file locations as requested. It may take up to 20 minutes for Security Platform Initialization Wizard to restore the security platform settings. 6. Start User Initialization Wizard. Select “Recover Your Basic User Key” when prompted.

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 D915PGN/D915PSY Technical Product Specification 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 39 lists the current capability of the fan connectors. Table 39.
Technical Reference 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 (as shown in Figure 27) to maintain required airflow across the processor voltage regulator area. OM16996 Figure 27.
Intel Desktop Board D915PGN/D915PSY Technical Product Specification 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 28) can reach a temperature of up to 85 C in an open chassis. Figure 28 shows the locations of the localized high temperature zones.
Technical Reference Table 40 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 40.

Intel Desktop Board D915PGN/D915PSY Technical Product Specification Table 45 lists the BIOS Setup program menu features. Table 45.
Overview of BIOS Features to PIO Mode 3 or 4, depending on the capability of the drive. You can override the autoconfiguration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: • An ATA-66/100 peripheral device • An ATA-66/100 compatible cable • ATA-66/100 operating system device drivers ✏ NOTE Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device.
Intel Desktop Board D915PGN/D915PSY 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. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6.
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 D915PGN/D915PSY Technical Product Specification 3.8 Fast Booting Systems with Intel® Rapid BIOS Boot These factors affect system boot speed: • Selecting and configuring peripherals properly • Using an optimized BIOS, such as the Intel® Rapid BIOS 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.
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 D915PGN/D915PSY Technical Product Specification Table 49. BIOS Error Messages (continued) Error Message Explanation 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. Memory Size Decreased Memory size has decreased 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.
