530 You can write floppies with SliTaz <i>bootfloppybox</i>,
531 <a href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply dd:
532 </p>
533 <pre># dd if=fd001.img of=/dev/fd0
534 </pre>
536 <p>
537 Start your computer with <i>fd001.img</i>. It will show the kernel version string and
538 the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.
539 </p>
541 <?php
542 if ($count >= 2) {
543 ?>
544 <p>
545 The floppy is then loaded into memory (one dot each 64k) and you will be prompted to
546 insert the next floppy, <i>fd002.img</i>. And so on.
547 </p>
549 <p>
550 The floppy set detects disk swaps and can be used without a keyboard.
551 </p>
552 <?php
553 }
554 ?>
555 <p>
556 Good luck.

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