You can write floppies with SliTaz bootfloppybox, Windows rawrite or simply dd:

# dd if=fd001.img of=/dev/fd0

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.

= 2) { ?>

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

The floppy set detects disk swaps and can be used without a keyboard.

Good luck.
