How to Upgrade BIOS on Linux


Upgrading your BIOS is a necessary task for all computer owners. Your BIOS is the main program that operates your computer--it is what tells all of your hardware how to work together, and it also loads your operating system when you boot up. As hardware and software advances, sometimes you need to upgrade your BIOS to the latest version to ensure that your computer will continue to work properly. The process of upgrading your BIOS is the same on a Linux computer as it is for any other operating system.

  • Locate both the manufacturer and the model of your BIOS setup. You can find this information in a few different ways. You can enter the Setup screen by hitting the "F2" key on your keyboard as your computer boots; you can quickly try to see the appropriate information as your computer is loading up; or you can physically open your case and look at your CPU. The information will be printed in small letters on the CPU itself.

  • Go to your BIOS manufacturer's website. Under the "BIOS" section of the page, locate your model. If there is an update available, it will allow you to download a utility program. Download this program and save it to your Desktop.

  • Copy the utility program to a floppy disk. Unfortunately, you cannot write this program to a CD--it needs to be on a floppy. If you don't have a floppy drive, you can purchase a cheap external floppy drive from any electronics retailer.

  • Restart your computer with the floppy disk in your floppy drive. As your computer boots, it will automatically detect the BIOS setup program contained on the floppy. It will automatically load the program. At this point, all you have to do is follow the onscreen instructions and then restart your computer when the program is done.
