Disklavier

Hello everyone. I have a quick question.  I am trying to update my Mark IV Disklavier to V4 (I am currently at V2).  I have the CD's created, backed up the Disklavier and was ready to go but I realized that the instructions mention that I need to load the update CD and install floppy.  I do not have an install floppy nor can I find any instructions how to create one.  Can anyone assist?  Is the install floppy just a Windows bootable floppy?  I was trying to get this done this weekend since I finally have some time and am really interested in controlling my Disklavier via my iPhone.  Thank you everyone.  Have a great 4th July!
