Using Enhanced Security

Enhanced Security can be enabled or disabled only when you update
system programs.
If Enhanced Security is enabled and you have not set an administrator
password, your computer will operate as though enhanced security is
disabled.
If enhanced security is enabled and you have set an administrator
password, your computer will operate as follows:
The contents of the security EEPROM (your administrator password
and startup sequence) will be protected from failure of the battery and
CMOS memory.
The security EEPROM will be protected from unauthorized access
because it locks after your computer is turned on and the system
programs have completed their startup routine. Once it is locked, the
security EEPROM cannot be read from or written to by any software
application or system software until the computer is turned off and
back on again. In a networking environment, this might prevent
certain functions from being performed remotely on your computer.
Enhanced Security adds a hard lock for 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 enables the Remote Administration program to
function in a network environment. With a hard lock, when your
computer is turned on and the system programs startup routine is
completed, Remote Administration 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 and enter the administrator password.
A chassis-intrusion feature will alert you if the cover of your computer
has been opened. This feature will work if your computer is on or off.
If the cover has been opened, a prompt for your administrator
