378 You can write floppies with SliTaz <i>bootfloppybox</i>,
379 <a href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply dd:
380 </p>
381 <pre># dd if=fd001.img of=/dev/fd0
382 </pre>
384 <p>
385 Start your computer with <i>fd001.img</i>. It will show the kernel version string and
386 the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.
387 </p>
389 <?php
390 if ($count >= 2) {
391 ?>
392 <p>
393 The floppy is then loaded into memory (one dot each 64k) and you will be prompted to
394 insert the next floppy, <i>fd002.img</i>. And so on.
395 </p>
397 <p>
398 The floppy set detects disk swaps and can be used without a keyboard.

413 This tool updates the boot sector of your kernel with
414 <a href="http://hg.slitaz.org/wok/raw-file/b84ff32e3457/linux/stuff/linux-header-2.6.34.u">this patch</a>.
415 You may add a default cmdline and an initramfs. The cmdline can be edited at boot
416 time but the keyboard is not mandatory.
417 A <a href="bootloader"> standalone version</a> is available.
418 </p>
419 <p>
420 Each part (boot, setup, cmdline, kernel, initramfs) is aligned to 512 bytes.
421 The result is split to fit the floppy size.
422 The last floppy image is padded with zeros.
