What Apple's Open Firmware does when a command like "dir hd:,\" is entered is it selects the partition that has the lowest partition number, and displays its files.

The other two partitions can be selected by doing this "dir hd:10,\" and "dir hd:11,\". Is there any more information that is needed to fix the auto selection system?

Do any of them have a system partition on? The reason I ask is that 
because on some of the debug traces you've sent me, a filesystem has 
been identified on the Apple_Driver43_CD partition. Therefore there must 
be some other logic involved with Apple's Open Firmware in order for it 
to locate the partition containing the installer.

I could perhaps see this behaviour as a fallback if there is no system 
partition on the disk which could explain this.
