3.9.2 Intel Rapid BIOS Boot

Use of the following BIOS Setup program settings reduces the POST execution time.
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.
•
Disable Quiet Boot, which eliminates display of the logo splash screen. This could save
several seconds of painting complex graphic images and changing video modes.
•
Enabled Intel Rapid BIOS Boot. This feature bypasses memory count and the search for a
diskette drive.
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 IDE Configuration Submenu
of the BIOS Setup program).

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:
•
The supervisor password gives unrestricted access to view and change all the Setup options in
the BIOS Setup program. This is the supervisor mode.
•
The user password gives access to view and change Setup options in the BIOS Setup program
based on the setting of the User Access Level option in the BIOS Setup Program's Security
Menu. This is the user mode.
•
If only the supervisor password is set, pressing the <Enter> key at the password prompt of the
BIOS Setup program allows the user access to Setup based on the setting of the User Access
Level option in the BIOS Setup Program's Security Menu.
•
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.
