Powering up for the first time

I originally posted this the the comp.sys.ibm-as400 group but other than someone wanting the disks I hd no replies, so I'll try here. I have connected everything and it is now time to power up my AS400 9404. There were 6 disks in the box with it. I'm not certain I have picked the correct 3 to start. What message might I see if the disks are not loaded in the correct order? Or might there be a label on the drive that takes care of that? Is there any external markings, of jumpers that might indicate the correct order? If it works, is there a way to gt to single user mode, or bypass the password? If I I get stuck is there a way to cleanly shutdown? If all else fails is there any interest in 9404 parts? Mike -- Ottawa, Canada Collector of vintage computers http://www.ncf.ca/~ba600
