Intel Desktop Board DP67BG Product Guide Back to BIOS Button The back panel Back to BIOS button (Figure 3, A) duplicates the functionality of the BIOS configuration jumper (see Setting the BIOS Configuration Jumper on page 55) with the following exceptions: • It can only be used to force the board to power on to the BIOS Maintenance Menu using default values but it will retain all previously saved changes. • It cannot be used to override passwords set in the BIOS. • It cannot be used to invoke BIOS recovery mode. The button glows red when it is activated. NOTE Using the Back to BIOS button does not set the board to the factory BIOS defaults. To restore settings to the factory defaults, use the key once BIOS setup mode is active. Figure 3.
