Thanks to the zillions of people who took the time to answer my query.
Here are excerpts from my original query:
>>

>>What I have:

>>3 ea. Sun-3/160 PROM level 1.5
>>1 ea. Sun-3/180 PROM level 1.5 (minimum PROM level stated as 1.8 for all)
>>
The concensus is that the problem referred to applies to booting from
tape, but booting over the net, or from a remote tape drive is not a
problem. Also many people are running 4.1.1 on systems with lower PROM
Rev. numbers without problems. I called my sales Guy, then called the
800 Sun number, and received an updated PROM on Monday (called Friday).
All is going relatively well with the upgrade so far.
Thanks again to everyone!!!
