510 <p>You can write floppies with SliTaz <code>bootfloppybox</code>, <a
511 href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply
512 <code>dd</code>:</p>
514 <pre># dd if=fd001.img of=/dev/fd0</pre>
516 <p>Start your computer with <tt>fd001.img</tt>. It will show the kernel version
517 string and the kernel cmdline line. You can edit the cmdline. Most users can
518 just press Enter.</p>
520 <?php
521 if ($count >= 2) {
522 ?>
523 <p>The floppy is then loaded into memory (one dot each 64K) and you will be
524 prompted to insert the next floppy, <tt>fd002.img</tt>. And so on.</p>
526 <p>The floppy set detects disk swaps and can be used without a keyboard.</p>
527 <?php

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