Use the Stepconf Wizard, it's just a case of inserting the appropriate numbers. The main ones to get right are the step count (i.e. 800 steps if your drives are set to 800 steps on the dip switches) and the parallel port pin numbers.

As a heads up, have you ran the latency test yet? Because LinuxCNC uses a realtime kernel, it can be a bit fussy on hardware. Onboard graphics and WiFi cards are the main culprits. If you really need to use a wifi card, there's a possible solution (for geeks!) HERE.
