I'm installing a short fence to run from the side of my house to the external garage. It will run along a seam where my asphalt driveway meets my concrete patio. I'm fairly certain that the footers will have to be on the concrete side in order to keep the fence from sticking out of from the side of the house.
My question is, is there a good way to dig the holes into the patio without having to break up the entire slab and re-pour it? Also, once I've dug the holes, is there something special I need to do when I set the footers in concrete since the concrete will be joined with the exiting patio?
EDIT:
I just wanted to clarify. I'm installing a wooden fence because the rest of the yard already has a wooden fence that I'm trying to match so I'm trying to avoid using chain-link.

What you want is something like this:
Get some Red-Heads or other appropriate concrete bolt and fasten it down. Slip the 4x4 in and tighten it up.
Ideally, you should still have some posts properly embedded in the ground to help support the torque caused by someone leaning on the fence, but you can use these in between.
