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) -- Brett Lymn Let go, or be dragged - Zen proverb.
