Narrative:

After being cleared for takeoff on runway 36R I asked the captain to set thrust and began the takeoff roll. At approximately 80 KTS we noticed that the screens on the first officer side blanked out for 2 or 3 seconds and the #2 yaw damper and the #2 generator both tripped off. We aborted the takeoff and the captain assumed the PF duties while I made the callouts and notified ATC of our rejected takeoff. We exited the runway and determined that the #2 generator had tripped offline during the takeoff roll. We returned to the gate and notified company operations as well as dispatch. No abnormalities were noted on the preflight or postflt of the #2 engine on the aircraft. After maintenance responded to the aircraft at the gate they informed us that the CSD was the problem; and proceeded to MEL the #2 CSD.
