Yes, I know what you are talking about.  I deal with Sun/Oracle
equipment at $WORK.  I have seen that prompt.  I have never seen any
documentation as to what you can do there.  I would be surprised if
there is anything available at all outside Oracle - I think the attitude
is that the customers don't need to mess with the SP at all and should
be treated just as a firmware blob (which is, in fact, how the updates
are provided - a blov for the linux image plus OFW update)
