The sentences in your description are each correct, but the overall message seems to me to miss the point, but it's probably a matter of interpretation. The problem under discussion occurs on machines with SCSI cards and IDE cards that do have onboard firmware and which are bootable. USB cards and Firewire cards are not even a part of the topic so far. When this problem occurs, the Start Up CP just doesn't work at all. The problem may be related to a SCSI card that is creating a SCSI Bus 2 and Bus 3, for example. But when the problem rears its head, if you assign a volume on SCSI Bus 1 (a built-in bus on the S900/J700 and x500 family) it will still be ignored if there is a bootable volume earlier in the search sequence. The problem is very simple to describe. The Start UP CP settings are ignored and the first bootable volume found using the default search (as you described end of 1st paragraph) is used by the computer. That's all there is to it. The cause is unknown but seems to relate to or correspond to the installation of some SCSI and IDE cards. But it's not that simple. Because it rarely occurs and sometimes it goes away for no *apparent* reason. It's probably somehow related to Open Firmware, but we just don't know.
