Wow that worked like a charm, keeping the PR54 in the same screen as the screen that appears when it first turns on. In the Midi menu there is a computer connection menu with the following choices: Normal, PC as Master, PR as Master, PR as Slave, and Interface. I was trying to upload download from that midi computer connection screen. So the answer to my question is the 9.X PR54 drivers do work in XP once one manages to get them installed in XP. Sure does beat using floppies.
