How to Flash (Update) Your Motherboard’s System BIOS
 

Recently Bob did an article on finding out the model of your motherboard. Since you usually find out the version of your board’s BIOS at the same time, I thought that an article on updating, or flashing, your BIOS would be a good idea. There were numerous articles on the subject back when I first got into building, and all of them involved a 3.5” floppy drive. Today, nearly all motherboards have multiple options for flashing the BIOS, and normally a floppy isn’t required.
