unauthorized  access  to  your  computer.  Users  may  enable  the  feature  in  the  Security  Option  of 
Advanced BIOS Features. If the Security Option is set to Always, you will be requested to enter the 
password before system boot and when entering BIOS setup; if the Security Option is set to Setup, 
you will be requested to enter the password before entering BIOS Setup.
