I'm just using 7.1 and 7.0.1. I don't have system 7.6 or anything else to boot up with. I mainly just want to test that this thing works. once I know that it works I'll go out and find 7.6. So is this why it's not working? Cause I'm using an OS that does not support this kind of a feature?

So then what you are saying is if I boot up with 7.6 and choose a different disk to start up with (say OS 7.1), the computer will not ignore my choice and restart and boot OS 7.1?
