226 You may add a default cmdline and an initramfs. The cmdline can be edited at boot
227 time but the keyboard is not mandatory.
228 A <a href="bootloader"> standalone version</a> is available.
229 </p>
230 <p>
231 Each part (boot, setup, cmdline, kernel, initramfs) is aligned to 512 bytes.
232 The result is split to fit the floppy size.
233 The last floppy image is padded with zeros.

361 You can write floppies with SliTaz <i>bootfloppybox</i>,
362 <a href="http://en.wikipedia.org/wiki/RaWrite">Windows rawrite</a> or simply dd:
363 </p>
364 <pre># dd if=fd001.img of=/dev/fd0
365 </pre>
366
367 <p>
368 Start your computer with <i>fd001.img</i>. It will show the kernel version string and
369 the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.

372 <?php

376 The floppy is then loaded into memory (one dot each 64k) and you will be prompted to
