For IPL using Tape System Save, Change the Panel to D M
Then start the system it will start from tape.
When you move disk controller cards between systems, it is vital that the cache is cleared before you do so otherwise you can/will end up with damaged objects. The best way to do this is to reinstall the card in the system it came out of and then power it up then shut it down cleanly. As it nears the end of its shutdown look for D5500xxxx on the control panel, when you see that code it is writing the cache out to the disks. Then you can reinstall it in your other system and power up.
Hope this helps
