Bootable floppy disks are generally used as a last resort to boot the installer on hardware that cannot boot from CD or by other means. Floppy disk booting reportedly fails on Mac USB floppy drives. Floppy disk booting is not supported on Amigas or 68k Macs. Disk images are files containing the complete contents of a floppy disk in raw form. Disk images, such as boot.img, cannot simply be copied to floppy drives. A special program is used to write the image files to floppy disk in raw mode. This is required because these images are raw representations of the disk; it is required to do a sector copy of the data from the file onto the floppy. There are different techniques for creating floppies from disk images, which depend on your platform. This section describes how to create floppies from disk images on different platforms. No matter which method you use to create your floppies, you should remember to flip the write-protect tab on the floppies once you have written them, to ensure they are not damaged unintentionally. To write the floppy disk image files to the floppy disks, you will probably need root access to the system. Place a good, blank floppy in the floppy drive. Next, use the command $ dd if=filename of=/dev/fd0 bs=1024 conv=sync ; sync where filename is one of the floppy disk image files (see for what filename should be). /dev/fd0 is a commonly used name of the floppy disk device, it may be different on your workstation (on Solaris, it is /dev/fd/0). The command may return to the prompt before Unix has finished writing the floppy disk, so look for the disk-in-use light on the floppy drive and be sure that the light is out and the disk has stopped revolving before you remove it from the drive. On some systems, you'll have to run a command to eject the floppy from the drive (on Solaris, use eject, see the manual page). Some systems attempt to automatically mount a floppy disk when you place it in the drive. You might have to disable this feature before the workstation will allow you to write a floppy in raw mode. Unfortunately, how to accomplish this will vary based on your operating system. On Solaris, you can work around volume management to get raw access to the floppy. First, make sure that the floppy is auto-mounted (using volcheck or the equivalent command in the file manager). Then use a dd command of the form given above, just replace /dev/fd0 with /vol/rdsk/floppy_name, where floppy_name is the name the floppy disk was given when it was formatted (unnamed floppies default to the name unnamed_floppy). On other systems, ask your system administrator. If writing a floppy on powerpc Linux, you will need to eject it. The eject program handles this nicely; you might need to install it. &floppy-i386.xml; &floppy-m68k.xml; &floppy-powerpc.xml;
