your server to regain access to the Configuration/Setup Utility
program.
If enhanced security is enabled and you have set an administrator
password, your server will operate as follows:

The security EEPROM is protected from unauthorized access
once the startup procedures are complete.
With enhanced security disabled, the contents of the EEPROM
are write protected, and the server can function in a network
environment because the POST/BIOS utility program will allow
updates to the system programs.
With enhanced security enabled, the POST/BIOS utility program
will not allow updates to the system programs. In a network
environment, this might prevent certain functions from being
performed remotely.

If the cover of your server has been removed, a
tamper-detection feature will halt system processing and deny
access to the keyboard and mouse until the administrator
