Problem is: How do I install the boot code on the drive? FreeDOS

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.
