mkbootdisk - Man Page

mkbootdisk [--version] [--noprompt] [--verbose]
          [--device devicefile] [--size size]
          [--kernelargs <args>] [--iso] kernel

mkbootdisk creates a boot floppy appropriate for the running system. The boot disk is entirely self-contained, and includes an initial ramdisk image which loads any necessary SCSI modules for the system. The created boot  disk looks for the root filesystem on the device suggested by /etc/fstab. The only required argument is the kernel version to put onto the boot floppy.

--device devicefile

The boot image is created on devicefile. If --device is not specified, /dev/fd0 is used. If devicefile does not exist  mkinitrd creates a 1.44Mb floppy image using devicefile as the filename.

--noprompt

Normally, mkbootdisk instructs the user to insert a floppy and waits for confirmation before continuing. If --noprompt is  specified, no prompt is displayed.

--verbose

Instructs mkbootdisk to talk about what it's doing as it's doing it. Normally, there is no output from mkbootdisk.

--iso

Instructs mkbootdisk to make a bootable ISO image as devicefile.

--version

Displays the version of mkbootdisk and exits.

--kernelargs args

Adds args to the arguments appended on the kernel command line. If this is not specified mkbootdisk uses grubby to parse the arguments for the default kernel from grub.conf, if possible.

--size size

Uses size (in kilobytes) as the size of the image to use for the boot disk.  If this is not specified, mkbootdisk will assume a standard  1.44Mb floppy device.
