Use a USB drive to flash your BIOS.
Due to the recent deprecation of floppy drives it has become useful to understand the process of updating your BIOS, Basic Input/Output System, from a USB flash drive instead. Updating a computer's BIOS is an important task that helps resolve compatibility issues and hardware failures. The process of updating a BIOS using a flash drive is an easy one that you can accomplish on any computer.
Instructions
1. Insert the bootable USB drive into an available USB port.
2. Copy the motherboard manufacturer's BIOS update files to the flash drive.
3. Restart the computer with the USB drive still inserted. Upon restarting, the computer will boot into DOS (Disk Operating System).
4. Type "cd G:\" (without quotes) to change the DOS location to that of your flash drive. This assumes your flash drive is the "G:\" drive. If it is not, simply substitute your USB drive's assigned letter into the command.
5. Type the name of the update executable into the DOS command prompt and press the "Enter" key. If you can not remember its name you may type "/dir" (without quotes) to see a listing of all files currently on the USB drive.
6. Follow any onscreen directions. Users are required in most cases to confirm they wish to update the BIOS and accept an end user license agreement.
7. Remove the USB drive and restart the computer when the process is complete to initialize the new BIOS firmware.
