Save the .exe file to a bootable media, like a CD/DVD, a USB drive, or a floppy diskette.
Do not remove the bootable media once the file is copied to it. -
Connect the drive to the primary master position in the computer.

Boot your computer from the bootable media, which will launch the firmware flash program.
