Intel D865GRH User Manual

21 

•  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. 

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 42 for the location of the chassis 
intrusion header. 

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 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. 

The desktop board has two power connectors.  See Figure 15 on page 42 for the location of the 
power connectors. 

The desktop board has two chassis fan connectors (Intel Precision Cooling Technology) and one 
processor fan connector.  See Figure 15 on page 42 for the location of the fan connectors.
