If you wait too long and your operating system begins to load into memory, let the system complete the load operation; then shut down the system and try again.

NOTE: To ensure an orderly system shutdown, consult the documentation that accompanied your operating system.

You can also enter the System Setup program by responding to certain error mes- sages. See “Responding to Error Messages” at the end of this chapter.

The System Setup screen displays the current setup and configuration information and optional settings for your system. (Typical examples are illustrated in Figure 2-1.) Information on the System Setup screen is organized in four areas:

‡Title box

The box at the top of the screen lists the system name.

‡System data

The two boxes below the title box display information about your system, such as the BIOS revision number.

‡Configuration options

The box under the system data boxes lists categories that define the installed hardware in your computer.

Fields beside the categories contain options or values; you can change those that appear in white on the screen. You cannot change options or values that appear in yellow because they are determined by the system.

Some categories have multiple fields, which may show options or values as bright or less bright depending upon what options or values you entered in other fields.

‡Key functions

The line of boxes across the bottom the screen lists keys and their functions within the System Setup program.
