PCA-6782 User Manual

AMI BIOS has been integrated into many many motherboards, and has been very
popular for well over a decade. People sometimes refer to the AMI BIOS setup menu
as BIOS, BIOS setup or CMOS setup.
With the AMI BIOS Setup program, you can modify BIOS settings and control the
special features of your computer. The BIOS Setup program uses a number of
menus for making changes and turning special features on or off. This chapter
describes the basic navigation of the PCA-6782 setup screens.

Figure 3.1 Setup Program Initial Screen

AMI's BIOS ROM has a built-in Setup program that allows users to modify the basic
system configuration. This information is stored in battery-backed up CMOS and it is
retained when the power is turned off.
