11. Move the jumper back to its normal position (pins 1 and 2).
12. Replace the air baffle and the metal cover.
13. Replace the computer cover.
14. Plug in the power cord.
After clearing CMOS memory, you must reconfigure the computer. After
reassembling the computer, use the Configuration/Setup Utility Program to reset
the date and time, reset any passwords, and reconfigure the computer.
Enhanced Security
By default, your administrator password is stored in CMOS memory. CMOS
memory is battery-powered memory that stores your configuration, setup, and
security settings. The information stored in CMOS remains there for the life of the
battery, as long as the battery is not removed.
Your computer has an enhanced security feature that provides extra protection for
your administrator password, as well as your startup (boot) sequence settings. With
enhanced security, your administrator password and boot sequence are stored in a
highly-protected, nonvolatile, security EEPROM module that is separate from CMOS
memory and the EEPROM module that stores system programs. When your
administrator password and boot sequence are locked in the security EEPROM, they
remain intact even if the battery in your computer expires or is removed by
someone.
Enhanced security can be enabled or disabled only when you update system
programs. The procedure for enabling enhanced security is explained under
“Enabling and Disabling Enhanced Security” on page 39.
If enhanced security is enabled and you have not set an administrator password,
your computer will operate as if enhanced security were disabled. If enhanced
security is enabled and you have an administrator password set, you computer will
operate as follows:
The contents of the security EEPROM (your administrator password and boot
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 locked, the security EEPROM cannot be
read from or written to by any 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.
