During an upgrade of OS/400 after LIC has been loaded and the message on the console says "Looking at Tape Drive for Operating System", (it looks for five minutes) remove the LIC CD and install the first Operating System CD. This will save you at least five minutes during the upgrade because if you wait for the message to change CD's, it will go back and look for the operating system on the tape drive again for five minutes before looking at the CD-ROM.
