Your Dell system is shipped to you without the system password feature enabled. If system security is a concern, operate your system only with system password protection. You can assign a system password, as described in "Assigning a System Password", whenever you use System Setup. After a system password is assigned, only those who know the password have full use of the system. When System Password is set to Enabled, the computer system prompts you for the system password just after the system boots.
Type the password and press . After you type the correct system password and press , your system boots and you can use the keyboard and/or mouse to operate your system as usual. NOTE: If you have assigned a setup password (see "Using the Setup Password Feature"), the system accepts your setup password as an alternate system password. If you enter a wrong or incomplete system password, the following message appears on the screen: ** Incorrect password.
If the two passwords are different, the setup password can be used as an alternate system password. However, the system password cannot be used in place of the setup password. After you verify the password, the Setup Password setting changes to Enabled. The next time you enter System Setup, the system prompts you for the setup password. A change to Setup Password becomes effective immediately (rebooting the system is not required).

Sometimes, after modifying the operating environment, you may need to reinstall a program that no longer runs properly. Memory-Resident Programs There are a variety of utilities and supplementary programs that can be loaded either when the computer boots or from an operating system prompt. These programs are designed to stay resident in system memory and thus always be available for use.
