494 <p>You can write floppies with SliTaz <code>bootfloppybox</code>, <a
495 href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply
496 <code>dd</code>:</p>
498 <pre># dd if=fd001.img of=/dev/fd0</pre>
500 <p>Start your computer with <tt>fd001.img</tt>. It will show the kernel version
501 string and the kernel cmdline line. You can edit the cmdline. Most users can
502 just press Enter.</p>
504 <?php
505 if ($count >= 2) {
506 ?>
507 <p>The floppy is then loaded into memory (one dot each 64K) and you will be
508 prompted to insert the next floppy, <tt>fd002.img</tt>. And so on.</p>
510 <p>The floppy set detects disk swaps and can be used without a keyboard.</p>
511 <?php

521 <h3>How does it work?</h3>
523 <p>This tool updates the boot sector of your kernel with <a
524 href="http://hg.slitaz.org/wok/raw-file/13835bce7189/syslinux/stuff/iso2exe/bootloader.S">this
525 code</a>. You may add a default cmdline and an initramfs. The cmdline can be
526 edited at boot time but the <acronym title="Check for disk swap every 5 seconds"
527 >keyboard is not mandatory</acronym>. A <a href="bootloader">standalone
528 version</a> is available to break the web server upload limit.</p>
530 <p>Each part (boot, setup, boot message, cmdline, kernel, initramfs) is aligned
531 to 512 bytes. The result is split to fit the floppy size. The last floppy image
532 is padded with zeros.</p>
534 <p>You can extract the <u>kernel</u>, <u>cmdline</u> and <u>rootfs</u> files
535 with <a href="bootloader" title="./bootloader --extract floppy.*">this tool</a>
536 from the floppy images.</p>
