Setup program 71 Intel Desktop Board D946GZAB Technical Product Specification 3 10 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer with the following restrictions e The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program This is the supervisor mode e The user password gives restricted access to view and change Setup options in the BIOS Setup program This is the user mode e If only the supervisor password is set pressing the Enter key at the password prompt of the BIOS Setup program allows the user restricted access to Setup If both the supervisor and user passwords are set users can enter either the supervisor password or the user password to access Setup Users have access to Setup respective to which password is entered Setting the user password restricts who can boot the computer The password prompt will be 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 the user can enter either password to boot the computer e For enhanced security use different passwords for the supervisor and user passwords Valid password characters are A Z a z and 0 9 P

This rate can influence POST execution time e Eliminate unnecessary add in adapter features such as logo displays screen repaints or mode changes in POST These features may add time to the boot process e Try different monitors Some monitors initialize and communicate with the BIOS more quickly which enables the system to boot more quickly 3 9 2 BIOS Boot Optimizations Use of the following BIOS Setup program settings reduces the POST execution time e In the Boot Menu set the hard disk drive as the first boot device As a result the POST does not first seek a diskette drive which saves about one second from the POST execution time e In the Peripheral Configuration submenu disable the LAN device if it will not be used This can reduce up to four seconds of option ROM boot time NOTE It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen or a custom logo splash screen will not be seen Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen This boot time may be so fast that some drives might be not be initialized at all If this condition should occur it is possible to introduce a programmable delay ranging from three to 30 seconds using the Hard Disk Pre Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS
