Intel Desktop Board DG41MJ Product Guide Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup and for booting the computer, with the following restrictions: • The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing at the password prompt of Setup gives the user restricted access to Setup. • If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered. • Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer. For instructions on resetting the password, see Clearing Passwords on page 46. Hardware Management Features The hardware management features of Intel Desktop Board DG41MJ enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following: • Fan speed monitoring and control • Thermal and voltage monitoring Hardware Monitoring and Fan Speed Control Features of the board's hardware monitoring and fan speed control include: • Monitoring of power supply voltages to detect levels above and below acceptable values. • Smart fan control provided by the legacy I/O controller, delivering acoustically- optimized thermal management. Fan speed controllers and sensors are integrated into the legacy I/O controller. • Thermally monitored closed-loop fan control, for onboard fans, that can adjust fan speed according to thermal conditions. • Two thermal sensors (processor and a remote thermal sensor). 18
