Net Display and Touchscreen setup problem in POS v1.0

While setting up MS POS 1.0 I couldn't find a way to add Net Display or Touchscreen to the register. It only gives me a list of the items to add in the register. And Net Display is not in the list. Control + F6 deosn't do anything either. I have no clue how to add that in register. I opened the table "register" using EMS SQL manager and found that both "Net Channel Display" and "Touchscreen" Fields are there, but they are not active (the argument is "false"). Nowhere in the MS POS Manager I could find any place where I can make those active. I am so much stuck with it at this moment that I don't think I can move ahead without solving these problems. have anyone faced similar situation before and if they have how it was resolved. Any help would be very much appreciated.
