Narrative:
At approximately 100 KTS on the takeoff roll; received a master warning light and aural alert. Aborted takeoff and cleared runway. EICAS warning went away when throttles were retarded. We did not see what the EICAS warning was. The left generator was off line also and would not reset. EICAS maintenance message thrust reverser failure would not clear. Returned to gate. Aircraft taken OTS. Supplemental information from acn 719682: clearing the runway; tower inquired as to the incident and asked if we needed assistance. We declined and discovered the left generator came off line with the associated load shed. We weren't able to determine if the generator loss was in some way tied to the takeoff warning indication.
