USB Boot via Floppy

I was wondering several time how to install an operating system which boot only from CD (ex TinyXp from Experience) on laptops without CDROMs , without BIOS option to boot from USB but with a floppy disk.

I was amazed when I found the answer in Linux.

1. Create a Floppy with PLoP BootManager on it.
2. Boot from the Floppy and install bootmanager on the HDD
3. Create a USB Stick with BootMyISO and put desired ISO CD image on it. --follow the instruction --
4. Restart and we'll have on screen options to boot from USB , HDD, Floppy

...rest is practice.
