457 You can write floppies with SliTaz <i>bootfloppybox</i>,
458 <a href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply dd:
459 </p>
460 <pre># dd if=fd001.img of=/dev/fd0
461 </pre>
462
463 <p>
464 Start your computer with <i>fd001.img</i>. It will show the kernel version string and
465 the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.
466 </p>
467
468 <?php
469 if ($count >= 2) {
470 ?>
471 <p>
472 The floppy is then loaded into memory (one dot each 64k) and you will be prompted to
473 insert the next floppy, <i>fd002.img</i>. And so on.
474 </p>
475
476 <p>
477 The floppy set detects disk swaps and can be used without a keyboard.
