This seems to be a FreeDOS floppy. If you can mount that image and have
a look inside you can probably find the firmware file itself, the
flasher program and probably the command used to launch it (look inside
autoexec.bat).

You could try downloading freedos, installing it to a usbkey and check
if it boots, if it does it is a matter of adding the flasher program,
the firmware file and launch it the same way it is launched in the
original image.
