Narrative:
On approach to dfw on cedar creek arrival. Approach control assigned a different runway ILS than what was in the CDU. When the newly assigned ILS was selected the altitude restriction at the tacke intersection was dropped out and I didn't catch it. The result was that the aircraft crossed the tacke intersection approximately 700 ft high. I informed approach control of the fact and he said ok; we received no TCAS warning. In the future I will be more diligent in checking that the proper altitude restrictions are reloaded when a new ILS is selected especially in a pegasus equipped aircraft.

Title: B757 FLT CREW EXPERIENCES MINOR ALT DEV WHEN CLOSE-IN RWY CHANGE WHILE ON A STAR RESULTS IN THE LOSS OF A PREVIOUSLY PROGRAMMED CROSSING ALT.
Narrative: ON APCH TO DFW ON CEDAR CREEK ARR. APCH CTL ASSIGNED A DIFFERENT RWY ILS THAN WHAT WAS IN THE CDU. WHEN THE NEWLY ASSIGNED ILS WAS SELECTED THE ALT RESTRICTION AT THE TACKE INTXN WAS DROPPED OUT AND I DIDN'T CATCH IT. THE RESULT WAS THAT THE ACFT CROSSED THE TACKE INTXN APPROX 700 FT HIGH. I INFORMED APCH CTL OF THE FACT AND HE SAID OK; WE RECEIVED NO TCAS WARNING. IN THE FUTURE I WILL BE MORE DILIGENT IN CHKING THAT THE PROPER ALT RESTRICTIONS ARE RELOADED WHEN A NEW ILS IS SELECTED ESPECIALLY IN A PEGASUS EQUIPPED ACFT.
