BIOS and CMOS Overview

Professor Messer | Jul 23, 2008 | Comments 3


What really happens when you start your computer? In this video, we’ll show you how the BIOS handles the most basic operations of your personal computer and how the CMOS stores all of your important configuration information. We’ll also show you how to use VMware Player or Microsoft Virtual PC to create a test lab on your computer where you can test BIOS changes without modifying your PC settings.

    I apprciate the warning of changing any BIOS settings and to always have a backup of your BIOS configs. Very simple to understand this caution. Thanks.
