That will depend if you can boot from the drive with a prepared floppy with the flash tool included as well as the correct bios. You will also need a copy of the same version at the root of the C drive on most systems. The one thing you can try first is a startup floppy already prepared for this. When in the drive and the system is restarted press the F8 key ro bring up the boot menu. Simply choose the "removable" or "floppy" option to test this.
