发明名称 Selection and control
摘要 A method of enabling a functional option in a computer type system is comprised of storing a serial number which is specific to the system, storing different codes each corresponding to a possible functional option which can be enabled in the system, selecting codes corresponding to desired functional options, combining the selected codes and the serial number to obtain a combined option code, receiving a password for enabling functional options corresponding to the selected codes, processing the password through a function apparatus or process to obtain a resultant password, comparing the resultant password with the combined options code, and enabling the desired functional options corresponding to the selected codes in the event the resultant password and the combined options code are the same.
