  Both warnings apply, regardless of the OS version you are running! As the
  INSTALL document already told you, xstreamtodev works on the _device_
  level and thus is limited to 32bit quantities (it was written before
  TD64/NSD were available when 4GB were unbelievable large ;-). If you feel
  adventures you could use a different tool that doesn't have the limitations
  of xstreamtodev to transfer the miniroot to your swap partition. Of course,
  you can mark a different partition as swap during installation and switch
  to the real swap partition later. Do NOT try writing to a partition
  beyound the 4GB barrier with xstreamtodev or you might loose other
  partitions!
  The booblocks are limited to <4GB for the root partition because the
  boostrap code in ROM has no idea about >4GB too (remember it was written
  in 1992 before TD64/NSD).
