Start your computer with fd001.img. It will show the kernel version string and the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.

The floppy is then loaded into memory (one dot each 64k) and you will be prompted to insert the next floppy, fd002.img.

The bootstrap will then start and you will be prompted to insert extra floppies from fd100.img to fd115.img.
