BIOS data resides in the system’s CMOS memory. When the system is powered on, BIOS data is copied or “shadowed” into the system’s dynamic memory and the system runs using BIOS parameters stored in dynamic memory.
BIOS Setup
BIOS Setup is a configuration utility that you can use to change your system’s permanent BIOS settings. The BIOS Setup application is stored in the BIOS flash ROM. (BIOS Setup values or settings are stored in CMOS memory.) Instructions for starting and running BIOS Setup are given in the following discussions.
Starting BIOS Setup
To start BIOS Setup, restart your system and when the following message is displayed,
<F2>, Double tap the pen+: BIOS Setup
The system starts BIOS Setup and the BIOS Setup Main menu is displayed. Note that the system can be configured to start without displaying the message above. If this is the case, you must attach an external keyboard and hold down the F2 key while you start your system until the BIOS Setup screen is displayed.
Options and settings for menus in BIOS Setup are described in tables appearing later in this chapter.
