Abstract
A gaming machine for conducting a wagering game comprises a processing apparatus and a secondary apparatus. To inhibit unauthorized persons from replacing some or all of the software executed by the processing apparatus with unapproved software, the processing apparatus transmits a security message to the secondary apparatus. The secondary apparatus, in turn, transmits an enable signal critical to machine function in response to successful validation of the security message. The secondary apparatus may, for example, be a programmable logic circuit external to the processing apparatus.
