About PC BIOS Updates
PC computers have their BIOS’ updated every once in a while. Sometimes a BIOS update can bring new functionality, and at other times it might fix some bugs. If you’re busy isolating tricky problems with a computer, it’s incredibly useful to update the BIOS.
Traditionally and to this day most BIOS updates rely on a DOS disk and some .EXE program that has to be run. The way to load the new BIOS is to create a DOS bootable disk, copy the .EXE program across, boot the PC, and then run the executable. To do this using Linux might not be that obvious but here we explain how to go about it.
Step 1 – Format USB Disk
Linux has built in utilities to format a USB disk. Either right click the disk after insertion, or look for a utility named
USB Stick Formatter or similar. Choose
FAT32 as the file system.
Step 2 – Download UNetbootin
To install UNetbootin on Ubuntu or Linux Mint, do the following:
sudo add-apt-repository ppa:gezakovacs/ppa
sudo apt-get update
sudo apt-get install unetbootin
Step 3 – Choose FreeDOS and Save to USB Drive
Once you have UNetbootin running, choose
FreeDOS from the dropdown menu, as per the image below:
Step 4 – Download BIOS File and Copy to USB Drive
Go to your manufacturer’s website and look for the download file. A typical google search might be something like:
gigabyte ga b75m d3h bios update download
Make sure you end up in the latest BIOS download section. Download the file and copy to root of the USB drive.
Step 5 – Boot from USB disk and change to drive C:
The key after booting from the drive is to change to drive C:
Here you will find your .EXE file which you can run.
