Ok, your BIOS is uncooperative. This is almost the same siyuation as
having a BIOS which cannot boot a CD/DVD.

I'd suggest you don't want to do this, whether it is doable or not.
There are two ways I can think of but let's have some more information
1. What is on this CD of yours? If it is a Debian image, please say
exactly which one it is.
2. Can the BIOS boot a USB stck?

Involving grub-install isn't necessary, but which bit of
grub-install [OPTION] install_device
requires de-mystifying? With a floppy I'd expect
to do the job.
