There is also one case we must support. If we don't chaos will result. Imagine hard coded partitions in Redboot. This is used to boot an eCos application. It also has hard coded partitions. However they are different! You are heading for trouble. We need that eCos applications can use Virtual Vectors to ask the eCos ROM redboot what the partitions are. The RAM app does not care where the ROM redboot gets the partitions from, be it hard coded, FIS. etc, so long as they are consistent with what redboot is using. Andrew
