[. . . ] Use this menu to clear passwords. Recovery (None) The BIOS recovers data in the event of a failed BIOS update. Clearing Passwords This procedure assumes that the board is installed in the computer and the configuration jumper block is set to normal mode. Observe the precautions in "Before You Begin" on page 25. Turn off all peripheral devices connected to the computer. Disconnect the computer's power cord from the AC power source (wall outlet or power adapter). Find the configuration jumper block (see Figure 27). Place the jumper on pins 2-3 as shown below. 6. Replace the cover, plug in the computer, turn on the computer, and allow it to boot. Use the arrow keys to select Clear Passwords.

To restore normal operation, place the jumper on pins 1-2 as shown below. 13. Replace the cover, plug in the computer, and turn on the computer. Replacing the Battery A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to 13 minutes/year at 25 C with 3. 3 VSB applied. When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 28 on page 60 shows the location of the battery. CAUTION Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled where possible. Disposal of used batteries must be in accordance with local environmental regulations. PRECAUTION Risque d'explosion si la pile usage est remplace par une pile de type incorrect. [. . . ] Pay close attention to the following when reading the installation instructions for the host chassis, power supply, and other modules: Product certifications or lack of certifications External I/O cable shielding and filtering Mounting, grounding, and bonding requirements Keying connectors when mating the wrong connectors could be hazardous If the power supply and other modules or peripherals, as applicable, are not Class B EMC compliant before integration, then EMC testing may be required on a representative sample of the newly completed computer. 83 Intel Desktop Board DP45SG Product Guide Product Certifications Board-Level Certification Markings Intel Desktop Board DP45SG has the product certification markings shown in Table 23.
