I'd expect this process would be nearly identical to cloning a floppy and
making a CD image of it.
A number of years ago now, I converted proprietary boot floppies to ISO
images (ex: a disk wiping program and a Win98SE boot floppy for updating
BIOSes).  Thank goodness for FreeDOS and BIOS updaters that are largely
compatible (if you find the right ones from the manufacturer).

So yes, use dd and mkisofs are the tools for the job -- as detailed [0]
