[Novalug] How the blazes do I write to a floppy?

[Beartooth]

 	That ancient laptop, now dbanned to a fare-thee-well, 
won't let me get to the BIOS to tell it to boot from a CD any 
more.

 	I *have* a boot floppy for grub which may let me do it -- 
but it's a .img file on my hard drive.

 	I also have an external USB floppy drive.

 	So how do I write the one to the other??

 	Crimenently,
