Okay, I understand all that part- that makes sense, but tell me this: I hooked up my external FW drive which I used as a boot drive in OS9 for maintenance, and for some reason, when I choose it in Startup Disk in OSX, it lets me choose the drive, but it won't boot off the FW drive. I now have to boot back into my OS9 partition and then go to Startup Control Panel in 9 to do it. Why won't X let me boot off my FW drive?
