Narrative:
Ground control had given us clearance to runway 22L for takeoff. At the last moment tower changed us to runway 27L. I turned onto a taxiway that looked like the entrance to runway 27L. I then turned onto the overrun area and taxied to the threshold of runway 27L. As I approached the runway end marker, I noticed a large green band across the overrun area and I remember thinking 'what's that doing here, I've never seen it here before.' as I passed over the runway end lines the tower informed me that we had used the 'overrun area' and cleared us for takeoff. It appears that I used taxiway Q which is a high speed turnoff for runway 4R, which crosses the overrun for runway 27L/9R, and enters the runway 27L pad from which we were coming. A factor in making this mistake was the last min change in runways and my concern that the first officer was setting FMC up correctly. I had picked a route to the end of runway that looked like the most 'natural way' there. Considering another factor, we had an earlier problem with autothrottle and I was planning on what to do if we got a split throttles situation. It was about this time also that the first officer finished his FMC work and I started discussing the throttle problem and what we might do. I guess I was not paying attention to where I was going. I had also missed the note on airport 20-9 page for ord.

Title: B777 TAXIED ONTO THE OVERRUN AREA OF RWY 9R WHEN TAXIING INTO POS ON RWY 27L. WRONG TAXI RTE WAS USED.
Narrative: GND CTL HAD GIVEN US CLRNC TO RWY 22L FOR TKOF. AT THE LAST MOMENT TWR CHANGED US TO RWY 27L. I TURNED ONTO A TXWY THAT LOOKED LIKE THE ENTRANCE TO RWY 27L. I THEN TURNED ONTO THE OVERRUN AREA AND TAXIED TO THE THRESHOLD OF RWY 27L. AS I APCHED THE RWY END MARKER, I NOTICED A LARGE GREEN BAND ACROSS THE OVERRUN AREA AND I REMEMBER THINKING 'WHAT'S THAT DOING HERE, I'VE NEVER SEEN IT HERE BEFORE.' AS I PASSED OVER THE RWY END LINES THE TWR INFORMED ME THAT WE HAD USED THE 'OVERRUN AREA' AND CLRED US FOR TKOF. IT APPEARS THAT I USED TXWY Q WHICH IS A HIGH SPD TURNOFF FOR RWY 4R, WHICH CROSSES THE OVERRUN FOR RWY 27L/9R, AND ENTERS THE RWY 27L PAD FROM WHICH WE WERE COMING. A FACTOR IN MAKING THIS MISTAKE WAS THE LAST MIN CHANGE IN RWYS AND MY CONCERN THAT THE FO WAS SETTING FMC UP CORRECTLY. I HAD PICKED A RTE TO THE END OF RWY THAT LOOKED LIKE THE MOST 'NATURAL WAY' THERE. CONSIDERING ANOTHER FACTOR, WE HAD AN EARLIER PROB WITH AUTOTHROTTLE AND I WAS PLANNING ON WHAT TO DO IF WE GOT A SPLIT THROTTLES SIT. IT WAS ABOUT THIS TIME ALSO THAT THE FO FINISHED HIS FMC WORK AND I STARTED DISCUSSING THE THROTTLE PROB AND WHAT WE MIGHT DO. I GUESS I WAS NOT PAYING ATTN TO WHERE I WAS GOING. I HAD ALSO MISSED THE NOTE ON ARPT 20-9 PAGE FOR ORD.
