You probably shouldn’t update your BIOS, but sometimes you need to.
You can upgrade your BIOS by floppy disk, CD or flash drive. As your computer boots, press the correct key, which will be displayed on the initial boot screen, to access your BIOS. You can use a public computer or a friend or family member's computer.
Your BIOS is determined by your motherboard manufacturer. The exact download location will vary based on the computer and motherboard manufacturer (see Resources).
