Hello, I know this is a question I could of been asking ten years ago, but bear with me. I thought I'd work on a computer that was ten years old to see how fast I could get it to run without spending a whole lot of money. And if something goes wrong then I'm not out a ton of money either. I am wondering if I can run a BIOS update for a Dell Dimension 4300 on a CD-ROM drive or does it have to be on a floppy disk?
