txtsetup is not the file that denotes files to copy. It is the file that says where files go when they are copied. You need all of the files added to dosnet.inf first, look in it its really straightforward. p3.sys = 1,,,,,,,4,0,0 Red is the location of the file originally "1" is the source disk. Only change this if you have properly denoted a new source location in txtsetup! Blue is where the file is to go this is the number you want to change. The better way would be to add them into cab files like drivers.cab (This is a whole nother very complicated can of worms.) in essence you need dosnet to tell the setup that the files are to be copied and then the txtsetup to tell setup where the files go...
