Intel Desktop Boards D865GBF/D865GLC 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 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. Chassis Intrusion The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 15 on page 44 for the location of the chassis intrusion header. Power Management Features Power management is implemented at several levels, including: • Advanced Configuration and Power Interface (ACPI) • Hardware support: Power connectors Fan connectors Fan Speed Control Suspend to RAM (Instantly Available PC technology) Resume on Ring Wake from USB Wake from PS/2 keyboard/mouse PME# wakeup support ACPI ACPI gives the operating system direct control over the power management and Plug & Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support. Power Connectors The desktop board has two power connectors. See Figure 15 on page 44 for the location of the power connectors. 22
