Enhanced Security

Enhanced Security

Note: Types 6565/6868/6878 have Enhanced Security Mode. If Enhanced Security mode is enabled and there is no password given, the computer will act as if Enhanced Security is disabled.
If Enhanced Security is Enabled and an administrator password is given, the administrator password must be entered to use the computer. If the administrator password is lost or forgotten, the system board in the computer must be replaced in order to regain access to the Configuration/Setup Utility program.

Enhanced Security is an additional security feature available on types 6565/6868/6878.

Enhanced Security can be enabled or disabled only when you update system programs. If Enhanced Security is enabled and the administrator password has not been set, the computer will operate as if Enhanced Security is disabled.

If Enhanced Security is enabled and the administrator password has been set, the computer has these additional security measures:

•  The contents of the security EEPROM (the  administrator password and startup sequence) are  protected if the battery or CMOS memory fails.
•  The security EEPROM is protected from unauthorized access.  The security EEPROM cannot be read from  or written to by any software application or system  software until Enhanced Security is disabled and the  computer is restarted. In a network environment, this  might prevent certain functions from being performed  on the computer.
•  Remote Administration is locked and cannot be  unlocked until Enhanced Security is disabled and the  computer is restarted. This prevents the system  programs in the computer from being updated  remotely.
•  The configuration settings in the Configuration/Setup  Utility program are protected and cannot be changed  until the administrator password has been entered.  Any changes in computer hardware detected by the  system programs in the computer will generate a  configuration error until the administrator password has been entered.

1.  Insert a system programs update diskette into the  diskette drive (drive A). System programs updates  are available at
   http://www.ibm.com/pc/support/us/
    on the World Wide Web.
2.  Power-on the computer. If it is powered on, you must  power-off then power-on.
3.  The update begins, the computer halts, and you are  prompted for the administrator password (if you have  set an administrator password). The computer  remains in a halted state until the administrator  password is entered.
4.  When the administrator password is entered, or if no  administrator password has been set, the update  diskette will continue to run, and you are given the  option of enabling or disabling Enhanced Security.  The choice is automatically recorded in the System  Security menu of the Configuration/Setup Utility program.
