Technical Reference Jumper Block CAUTION Do not move the jumper with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the board could be damaged. Figure 12 shows the location of the jumper block. The jumper determines the BIOS Setup program’s mode.
Intel Desktop Board D945GCLF2 Technical Product Specification Mechanical Considerations 2.4.1 Form Factor The board is designed to fit into a micro-ATX-form-factor chassis. Figure 13 illustrates the mechanical form factor for the board. Dimensions are given in inches [millimeters]. The outer dimensions are 6.75 inches by 6.75 inches [171.45 millimeters by 171.45 millimeters].
For example, for a system consisting of a D945GCLF2 board (with integrated Dual- Core Intel Atom processor at 8 W), 2 GB DDR2 RAM, one hard disk drive, one optical drive, and all board peripherals enabled, the minimum recommended power supply is 80 W.
Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board. For a list of chassis that have been tested with Intel Desktop Boards please refer to the following website: http://developer.intel.com/design/motherbd/cooling.htm...

Overview of BIOS Features System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components.
Legacy USB support from the BIOS is no longer used. 7. Additional USB legacy feature options can be access by using Intel Integrator Toolkit. To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s...
Integrator’s Toolkit that is available from Intel can be used to create a custom splash screen. NOTE If you add a custom splash screen, it will share space with the Intel branded logo. Refer to For information about Intel Integrator Toolkit http://developer.intel.com/design/motherbd/software/itk/...
Intel Desktop Board D945GCLF2 Technical Product Specification BIOS Recovery It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. Table 28 lists the drives and media types that can and cannot be used for BIOS recovery. The BIOS recovery media does not need to be made bootable.
Overview of BIOS Features Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drive, USB drive, USB flash drive, 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.
It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen.
Overview of BIOS Features 3.10 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: •...
Error Messages and Beep Codes BIOS Front-panel Power LED Codes The front-panel power LED blinks off and on to display messages. For example, the power LED is on when the system is powered on, and blinks off for 0.5 second when processor initialization is complete.
(see Table 32). NOTE For Intel Desktop Board D945GCLF2, the beep code is only audible through a speaker connected to the green audio line out connector on the back panel. See Figure 3 on page 23 for information on the back panel audio connectors.
Error Messages and Beep Codes 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.
