Narrative:
We thoroughly checked and rechked the route and TRISS2 departure out of dfw for runway 18L. We got a runway change to runway 17R and input that into the FMS. We confirmed the runway and first departure point with queue and internally confirmed the next 3 points on the departure with the new runway in the box. Center called us as we were passing approximately 4 miles north of shero. We double checked the FMS and we were heading to matie which was on our route of flight. We discovered that when we switched runways from 18L to runway 17R; the FMS dropped the last 2 points on the TRISS2 departure. We subsequently cleared to txk and rest of the route unchanged. Flight progressed to destination uneventfully.supplemental information from acn 683450: I was never instructed to rebuild a departure when the runway is changed -- only to change the runway. I had to learn the hard way how to reselect a runway. It should be taught and/or the software in the FMS needs to be changed.

Title: MD80 FLT CREW FAIL TO REPROGRAM TRANSITION PORTION OF THE TRISS RNAV DEP FROM DFW WHEN ATC CHANGES RWY PRIOR TO TKOF.
Narrative: WE THOROUGHLY CHKED AND RECHKED THE RTE AND TRISS2 DEP OUT OF DFW FOR RWY 18L. WE GOT A RWY CHANGE TO RWY 17R AND INPUT THAT INTO THE FMS. WE CONFIRMED THE RWY AND FIRST DEP POINT WITH QUEUE AND INTERNALLY CONFIRMED THE NEXT 3 POINTS ON THE DEP WITH THE NEW RWY IN THE BOX. CTR CALLED US AS WE WERE PASSING APPROX 4 MILES N OF SHERO. WE DOUBLE CHKED THE FMS AND WE WERE HEADING TO MATIE WHICH WAS ON OUR RTE OF FLT. WE DISCOVERED THAT WHEN WE SWITCHED RWYS FROM 18L TO RWY 17R; THE FMS DROPPED THE LAST 2 POINTS ON THE TRISS2 DEP. WE SUBSEQUENTLY CLRED TO TXK AND REST OF THE RTE UNCHANGED. FLT PROGRESSED TO DEST UNEVENTFULLY.SUPPLEMENTAL INFO FROM ACN 683450: I WAS NEVER INSTRUCTED TO REBUILD A DEP WHEN THE RWY IS CHANGED -- ONLY TO CHANGE THE RWY. I HAD TO LEARN THE HARD WAY HOW TO RESELECT A RWY. IT SHOULD BE TAUGHT AND/OR THE SOFTWARE IN THE FMS NEEDS TO BE CHANGED.
