This is convered the documentation, System Backup and Restore (in my
version it is on page 3-14).
In summary, after making the proper files in /dev and mounting the disk
(see the sequence in the docs), use 'dd' to copy the boot block to the
disk - 'something like'
# dd if=/vaxboot of=/dev/r*0a conv=sync
where * is your RD53 (probably 'ra').
