- This must tie the EFI_DEVICE_PATH to /boot/efi/elilo.efi
- The EFI_DEVICE_PATH will look something like:
- ACPI device path, length 12 bytes
- Hardware Device Path, PCI, length 6 bytes
- Messaging Device Path, SCSI, length 8 bytes, or ATAPI, length ??
- Media Device Path, Hard Drive, partition XX, length 30 bytes
- Media Device Path, File Path, length ??
- End of Hardware Device Path, length 4
- Arguments passed to elilo, as UCS-2 characters, length ??
