Virus protection Your computer has built-in virus protection that can be enabled through the Configuration/Setup Utility program. In addition, Norton AntiVirus for IBM is available on the IBM Software Selections CD. For further information about Norton AntiVirus for IBM or other software, see About Your Software. Enhanced security Your computer has an enhanced security feature that provides extra protection for your administrator password and your startup sequence settings. With enhanced security, your administrator password and startup 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 security sequence are protected by enhanced security, they remain intact even if the battery in your computer expires or is removed by someone. For more information, see "Using Enhanced Security" on page 46. Locking the keyboard You can disable the keyboard so that others are unable to use it. If a power-on password is set, the keyboard is locked when you turn on the computer. You must type the correct password before the keyboard will unlock. You can enable the power-on password feature with the Configuration/Setup Utility program. See Chapter 4, "Using the Configuration/Setup Utility program" on page 37. Some operating systems have a keyboard and mouse lock-up feature. Check the documentation that comes with your operating system for more information. Chapter 3.
