A method and system controls an optical disk driver (ODD) of a computer. The method detects whether an eject button connected with an I/O (input/output) chip of the computer has been pressed, and determines if an optical disk exists in the ODD when the eject button has been pressed. Additionally, the method sends a control signal to the ODD, and control the ODD to eject the optical disk when the optical disk exists in the ODD.
