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 a memory DIMM, 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 PC. To enable or disable enhanced security: 1. Insert a system programs update diskette into drive A in your computer. System programs updates are available on the World Wide Web. (Refer to "System Programs" on page 28 for further information on updates.) 2. Turn on the computer. If it is on already, you must turn it off and back on again. 3. 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. 4. When you enter the administrator password, the update diskette will continue to run, and 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. Setting, Changing, and Deleting an Administrator Password Protected by Enhanced Security To set, change, or delete an administrator password protected by enhanced security, do the following: 1. Turn off all attached devices and the computer. 2. Refer to Installing Options in Your Personal Computer for instructions on safety, disconnecting all cables attached to the computer, and removing the computer cover. 3.
