Professor Messer’s Free CompTIA A+ Certification Training Course – BIOS and CMOS

CompTIA A+ Videos /

What really happens when you start your computer? In this chapter, 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 your BIOS changes without modifying your PC settings.
