How to Upgrade BIOS Firmware
The BIOS is the name of the main piece of hardware that runs your entire computer. "Firmware" is the name of the computer program that runs your BIOS. Occasionally your BIOS manufacturer will release firmware upgrades for your BIOS. You will need to download and install these firmware upgrades onto your machine to make sure that your computer is up to date and can interact with all of the latest software and hardware components that are available.

Find out which company manufactured your BIOS, as well as your BIOS' model number. You can check for this inside the manual that came with your computer. If you can't find the manual, you can open up your computer and look at the BIOS, which is located in the center of your motherboard--the information will be printed on the chip itself. If you don't want to open your computer, look online for reviews of your computer to find this information.
