Narrative:

During takeoff roll, runway 18L dfw, mach airspeed warning (clacker) sounded at approximately 80 KTS. Clacker remained on continuously and takeoff was aborted at 90 KTS. Maximum braking was not applied due to 9500 ft remaining runway available. Aircraft parked on taxiway F to allow brake cooling limitations. Following maintenance and dispatch deferrals, the flight departed normally.
