This machine has a NEC PC9801UV computer and I am trying to initialize a floppy disk to copy system to it. When I select "user initialize" it says put disk in drive 2 and hit enter. I do that and nothing happens. The light on the floppy doesn't come on at all and the computer locks up. Also, none of the soft keys do anything. Is there something in the parameter lists that need to be set or changed?
