The itanium is up-to-date for 8.4. I know about the Efi-thing, but I
thought that also the boot-block was saved in the bqackup file.
ana/disk.repair does not work because it has a problem with the
filesystem. The plan was to do the writeboot, but I stopped when I could
not mount the disk and check the contents.
