mkisofs can be used to create bootable CDs with a DOS floppy image. 
The DOS system has to set up CD support, and the additional files end up 
being on that "drive".  See

man -P'less -p eltorito_boot' mkisofs

This worked for me with a Win95 install floppy, which sets up the CD 
drive correctly.  I don't know if FreeDOS is compatible enough to be a 
safe way to try BIOS upgrades.
