Greetings and thank-you for the two responses.

Answer to the first question - yes, I have the actual SUN Sparc 2.5.1 CD's.
Just ripped open the plastic on the documentation package (from the Solaris
2.5.1 package) yesterday to see if there are any hints.

Second question - I need Solaris 2.5.1 for an old app. It (unfortunately)
does not run on anything newer and I do not have the time to hack it. I
have run Solaris 10 on the Ultra 80 with no problems.

I did see the footnote and thought it was related to process speed (anything
above 400 MHz), so I pulled the four 450 MHz processors and installed a (1)
360 MHz processor (and set the jumper correctly - 1-2 from 2-3). No luck.
So, I thought that perhaps it was related to the Elite-3D video cards so I
pulled both of these out and installed a single Creator-3D. Still no luck.
Guess I do need the Operating Environment Installation CD February 2000
(704-7076-10). I looked in the Sun website with no luck. I will try Sun to
see what they say ... hopefully someone has some other ideas that I could
use for a Plan B.

Thanks for the suggestions so far
