BIOS Setup configuration
Your IBM Aptiva Personal Computer is already configured for 
immediate use. You can view your computer’s configuration 
settings using the Configuration/Setup Utility and the 
Windows 95 Device Manager.
You can also use these configuration utilities to change 
some configuration settings. For instance, if you add or 
replace hardware inside your system unit, you might need to 
verify or update specific settings. For information about 
working with your system unit’s hardware, see “Part 4: 
Upgrading and replacing hardware”.
This chapter contains the following sections to help you 
reconfigure and optimize your computer:
 “Configuration/Setup Utility overview” on page 5-1
 “Entering Setup” on page 5-3
 “Working with the Setup menus” on page 5-4
“Setup parameters” on page 5-7
“Using other configuration utilities” on page 5-18
Configuration/Setup Utility overview
The
 
Configuration/Setup Utility lets you view and change 
important information about your computer and its hardware. 
You might need to use Setup if you upgrade the hardware in 
your computer or if you get an error message while using 
your computer.
In most circumstances, when you add or replace hardware 
in your system unit, your computer’s Basic Input/Output 
System (BIOS) detects the hardware changes and updates 
Setup parameters automatically. In some cases, however, 
especially if you purchase hardware that does not meet Plug 
and Play requirements, you might need to manually change 
the configuration information in Setup. If you add or remove 
hardware, an online message may ask you to check Setup 
to verify that automatic detection made the correct 
configuration changes.
Note:
For simplification, the Configuration/Setup Utility will be 
referred to simply as “Setup” throughout this handbook.
