Chapter 2 The BIOS Setup
2.1 Configuration Software
The notebook can easil y be configured to suit your personal needs. The built-in SETUP
program allows you to setup various system parameters. The information is stored in a
battery-backed CMOS memory; so when the power is turned off, your setup is retained.
This Configuration Software is sometimes referred to as CMOS Setup, BIOS Setup, or
simply the SETUP.
Note: The SETUP can be activated by pressing <F2> during system boot-up.
You are requested to perform the following one-time procedure immediately after you have
upgraded/reprogrammed your BIOS:
• Press <F2> during system boot-up to get into the SETUP.
• Go to the EXIT sub-menu and choose Load Setup Defaults. Press Enter.
• Now, you can customize the BIOS for your personal needs.
For detail on the BIOS SETUP, read on.
Note: For information on the BIOS upgrade, contact your local notebook dealer.
