There is an extra measure of protection for the system programs in your
computer. Normally, the entire contents of the system programs EEPROM is
write protected with a soft lock. A soft lock allows the POST/BIOS update
utility to function in a network environment. Enhanced security adds a hard
lock. With a hard lock, when your computer is turned on and the system
programs startup routine is completed, the POST/BIOS update utility is locked
and cannot be unlocked until the computer is turned off and back on again and
the administrator password is entered. Note that, in a networking environment,
this prevents the system programs in your computer from being updated
remotely. Someone must be present at your computer to turn it on and off in
order to unlock the POST/BIOS update utility.
A chassis-intrusion feature will alert you if the computer cover has been
removed. This feature will work even if your computer is off when the cover is
removed. If the cover has been removed, a prompt for your administrator
password will appear on the screen, and your computer will remain in a halted
state until your administrator password is entered.
As with nonenhanced security, your configuration settings are protected. The
settings cannot be changed in the Configuration/Setup Utility program until
your administrator password is entered. This means that any changes in
computer hardware that are detected by the system programs in your computer,
such as removal of an adapter, will generate a configuration error until the
administrator password is entered.
Enabling and Disabling Enhanced Security:
Enhanced security can be
enabled or disabled only when you update the system programs in your computer.
1. Shut down the operating system and turn off the computer.
2. Insert a system programs update diskette into drive A in your computer.
System programs updates are available on the World Wide Web.
3. Turn on the computer.
4. The update begins, your computer halts, and you are prompted for your
administrator password (if you have set an administrator password). The
computer remains in a halted state until you enter the administrator password.
5. As the update diskette runs you are given the option of enabling or disabling
enhanced security. Your choice is automatically recorded in the System Security
menu of the Configuration/Setup Utility program.
