Problem
Describe the model and make of your computer. Then find the BIOS/CMOS version number or firmware number. Now, go to the computer manufacturer's website (or Motherboard manufacturer's website) and see if there is a newer version of the CMOS or BIOS for your computer. Describe what the steps are that you have to take to upgrade it. What could go wrong with the upgrade? What improvements will you get from the upgrade? Describe in detail. Is there a way to "undo" this change?
