RS/6000 AIX release code

[Wendy Ross]

I am trying to set up a "release" code template on a server machine to 
use for network loading.  I have a 9021 bos image, which I dd'd
from the 9021 tape.  We tried dd'ing our SE's "release" tape, but to no
avail for some reason, which might have to do with the fact that our tape
drives (cartridge) need hardware upgrades, but we aren't sure because
no-one seems to know for sure what the tape hardware upgrades are supposed 
to do.  In addition, his "release" tape is in a different format than
the 9021 tape, and is apparently bootable.

Could someone please help?  Is 9021 the release version?  What are the
different versions floating around out there?  What are the preloaded
machines preloaded with?  How do I make a bos image for network installation
from a "release" bootable tape?  What are the tape hardware upgrades
supposed to do, anyhow?  Who really shot J.R.?
 
Many thanks to whomever can help.
