526 You can write floppies with SliTaz <i>bootfloppybox</i>,
527 <a href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply dd:
528 </p>
529 <pre># dd if=fd001.img of=/dev/fd0
530 </pre>
531
532 <p>
533 Start your computer with <i>fd001.img</i>. It will show the kernel version string and
534 the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.
535 </p>
536
537 <?php
538 if ($count >= 2) {
539 ?>
540 <p>
541 The floppy is then loaded into memory (one dot each 64k) and you will be prompted to
542 insert the next floppy, <i>fd002.img</i>. And so on.
543 </p>
544
545 <p>
546 The floppy set detects disk swaps and can be used without a keyboard.
547 </p>
548 <?php
549 }
550 ?>
551 <p>
552 Good luck.

561 This tool updates the boot sector of your kernel with
562 <a href="http://hg.slitaz.org/wok/raw-file/13835bce7189/syslinux/stuff/iso2exe/bootloader.S">this code</a>.
563 You may add a default cmdline and an initramfs. The cmdline can be edited at boot
564 time but the <acronym title="Check for disk swap every 5 seconds">keyboard is not mandatory</acronym>.
565 A <a href="bootloader"> standalone version</a> is available to break the web server upload limit.
566 </p>
567 <p>
568 Each part (boot, setup, boot message, cmdline, kernel, initramfs) is aligned to 512 bytes.
569 The result is split to fit the floppy size.
570 The last floppy image is padded with zeros.
571 </p>
572 <p>
573 You can extract the <u>kernel</u>, <u>cmdline</u> and <u>rootfs</u> files with
574 <a href="bootloader" title="./bootloader --extract floppy.*">this tool</a> from the floppy images.
