20 FUNCTION
21
22 Installs the GRUB 2 bootloader to the boot block of the specified
23 disk or partition.
24
25 INPUTS
26
27 DEVICE -- Device name (e.g. ata.device)
28 UNIT -- Unit number
29 PN -- Specifies a partition number. If specified, GRUB is installed
30 to this partition's boot block. Otherwise, GRUB is installed to
31 the disk's boot block.
32 GRUB -- Path to GRUB directory.
33 FORCELBA -- Force use of LBA mode.
