I have installed TAPIT on a lot of systems without problems, but I have not put it on an OS7100.

I know you'd like a quick answer, but I don't have one. I'll try to get time early next week to load TAPIT on a spare machine at the office and connect it to our OS7100 in the lab.

Did you talk directly to Samsung Tech Support or was it your distributor?

Feel free to send me a PM so when can get into more in depth discussions.
