Fellow Apollo admin persons:

	I'm trying to install SR 10.2 on a DN3500 for
the first time (both it and myself are virgins
at this point.)  All goes well through system testing
and so forth until I try to actually load some of
the kernal from the CRTG_STD_SFW_BOOT_1 tape. 
(Command from the installation instructions is
EX DOMAIN_OS, from this tape.)  The behavior
that I'm seeing is as follows:

	It searches through the tape for domain_os,
    finds and begins to execute same.

	Tells me that is is loading numberous files 
	onto the winchester.

  **Stops with the following error message:
		**UID in block header does not match
		  those read from earlier blocks.

  This is followed by the correct UID number and 
  the incorrect (new) one, which appear to be the
  same only shifted right 8 bits:

	Correct UID:  4699DC2F.800181BE
    bad UID     804699DC.2F800181

My question is: Should I consider this to be a tape 
error, or should I look for some basic error that I
am introducing in the installation process?

I'll be working with HP/Apollo techs directly on this,
of course, but I'm really interested in what's actually
happening here.  I'm an experienced HP 9000 series 
system manager, but just NOW starting to learn the 
Apollo way of life.  

Speaking of the Apollo way of life.  I don't see a really
thorough explanation of EXACTLY WHAT is HAPPENING throughout
the load of the OS anywhere.  Have I missed the box with 
all the goodies?  

Thanks in advance for any information you direct my way, I
guess I had forgotten what it's like to do parallel system
loads; Domain OS -> DN3500 ; Domain OS -> my brain.
