511 You can write floppies with SliTaz <i>bootfloppybox</i>,
512 <a href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply dd:
513 </p>
514 <pre># dd if=fd001.img of=/dev/fd0
515 </pre>
517 <p>
518 Start your computer with <i>fd001.img</i>. It will show the kernel version string and
519 the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.
520 </p>
522 <?php
523 if ($count >= 2) {
524 ?>
525 <p>
526 The floppy is then loaded into memory (one dot each 64k) and you will be prompted to
527 insert the next floppy, <i>fd002.img</i>. And so on.
528 </p>
530 <p>
531 The floppy set detects disk swaps and can be used without a keyboard.
532 </p>
533 <?php
534 }
535 ?>

537 Good luck.

546 This tool updates the boot sector of your kernel with
547 <a href="http://hg.slitaz.org/wok/raw-file/66e38bd6a132/linux/stuff/linux-header.u">this patch</a>.
548 You may add a default cmdline and an initramfs. The cmdline can be edited at boot
549 time but the <acronym title="Check for disk swap every 5 seconds">keyboard is not mandatory</acronym>.
550 A <a href="bootloader"> standalone version</a> is available.
551 </p>
552 <p>
553 Each part (boot, setup, boot message, cmdline, kernel, initramfs) is aligned to 512 bytes.
554 The result is split to fit the floppy size.
555 The last floppy image is padded with zeros.
556 </p>
557 <p>
558 You can extract the <u>kernel</u>, <u>cmdline</u> and <u>rootfs</u> files with
559 <a href="../floppies">this tool</a> from the floppy images.
