I have an enclosed patio over the garage. The floor gets very cold. We were going to put down a carpet tile system with built in backing. I thought I'd put down plywood as an extra layer to block out the cold. (There aren't moisture problems at all.) How would I attach the plywood to the concrete?

there are "tapcon screws" .they are made to screw into the concrete, and you predrill a hole in the concrete with a masonary bit and screw through the plywood to secure. how many screws you put in depends on your thickness of plywood and how much it is naturally twisted or bowed.

the carpet will block some of the cold and keep the floor warmer to your feet. the plywood is not really nessessary but will make a thermal break from the concrete to the carpet.

on this supended slab(i am guessing) you may hit some rebar when drilling.

You'd place treated sleepers first, any contact with concrete you'll need to use a treated wood.

You can get away with 1x' if you are short on space but 2x are recommended.

What you'll be doing is trapping moisture in between the ply & the concrete and it WILL happen... even with a 6mil vapor barrier.

The reason to use 2x4 is you can then get isocyanurate or similar vapor backed or reflective backed insulation to place in the bays.

You could also place a decent grade floating floor system similar to ALLOC from Norway if you use the barrier they provide... I've heard horror stories with pergo used directly on concrete though so use a well engineered product if you decide to go that way.
