It’s been a very long time since I partitioned an ES47/GS80 (would have been whilst I worked for Compaq prior to the HP takeover) but ISTR that the reason for the 2P rule was that you couldn’t partition the memory subsystems within a dynamic duo. It’s been a long time and I no longer have access to the appropriate documentation so I could be recalling incorrectly. I don’t even have an ES47 at work anymore to play around with :-(
