Usage: grub-bios-setup [OPTION...] DEVICE

Set up images to boot from DEVICE.

You should not normally run this program directly.  Use grub-install instead.

  -a, --allow-floppy         make the drive also bootable as floppy (default
                             for fdX devices). May break on some BIOSes.
  -b, --boot-image=FILE      use FILE as the boot image [default=boot.img]
  -c, --core-image=FILE      use FILE as the core image [default=core.img]

                             [default=/boot/grub]
  -f, --force                install even if problems are detected
  -m, --device-map=FILE      use FILE as the device map
