Chapter 6. Working with Security Options

This chapter describes some of the security options that are available for your
computer.

To help prevent hardware theft, you can add a security U-bolt and cable to your
computer. To erase lost or forgotten passwords, you can move the CMOS clear
(password) jumper on the system board.

Note:

Use the Configuration/Setup Utility program to set, change, or delete
passwords. For more information, see Using Your Personal Computer.

The following list is a quick reference to these procedures:

“Installing a U-Bolt” on page 68

“Erasing Lost or Forgotten Passwords” on page 70
