ystem Setup Screens
The two System Setup screens, Page 1 and Page 2,
display the current setup and configuration information
and optional settings for your system. (Typical examples
are illustrated in Figure 2-1.) Information on the two
System Setup screens is organized in five boxed areas:
•Title box
The box at the top of both screens lists the system
name, page number (Page 1 or Page 2), and the
revision number of the basic input/output system
(BIOS).
•Configuration options
The box on the left half of both screens lists the
categories that define the installed hardware in your
computer.
Fields beside the categories contain options or
values; those that appear bright on the screen can be
changed. Options or values that you cannot change
because they are determined by the system appear
less bright.
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.
•Help
The box on the upper-right half of both screens
displays help information for the category with a
currently highlighted field.
•System data
The box in the lower-right corner of both screens
displays information about your system.
•Key functions
The line of boxes across the bottom of both screens
lists keys and their functions within the System
Setup program.
