you should in your cameras custom settings menu have a selection that says something to the affect of bracketing/flash. in that menu you will see flash control for built in flash. inside that menu you should see commander mode. inside that menu you should see built in flash, group a, group b. go to built in flash and in the mode box use your multi selector nob to move that to -- that will turn the flash output on the onboard off and it will just fire the preflash.
