Abstract
A mass storage data protection system for use with a mass storage device in a gaming machine to protect the mass storage device from unauthorized commands. The mass storage data protection system includes a mass storage device command latch, a timing circuit for timing signals between the mass storage device command latch and the mass storage device, a comparator and a comparator command register in communication with the comparator. The comparator command register includes commands that generate a fault within the mass storage data protection system such that when the comparator receives a command from the mass storage device command latch corresponding to the command within the comparator command register, a fault is generated within the mass storage command latch.
Claims14
A mass storage data protection system for use with a mass storage device in a gaming machine, the mass storage data protection system comprising:
- a mass storage device command latch;
- a timing circuit for timing signals between the mass storage device command latch and the mass storage device;
- a comparator between the mass storage device command latch and the timing means;
- and
- a comparator command register in communication with the comparator, the comparator command register including commands that generate a fault within the mass storage data protection system;
- wherein when the comparator receives a command from the mass storage device command latch corresponding to a command within the comparator command register, a fault is generated within the mass storage command latch.
A mass storage data protection system for use with an intelligent drive electronics mass storage device in a gaming machine, the mass storage data protection system comprising:
- an intelligent drive electronics command latch;
- a timing circuit for timing signals between the intelligent drive electronics command latch and the intelligent drive electronics mass storage device, the timing circuit comprising a synchronizer and a reset generator;
- a comparator comprising a fixed command array and a user command array, the comparator being located between the intelligent drive electronics command latch and the timing circuit;
- a comparator command register in communication with the comparator, the comparator command register including commands that generate a fault within the mass storage data protection system;
- and
- a control and status register in communication with the comparator command register and the comparator, the control and status register being configured to at least partially control functioning of the mass storage data protection system;
- wherein when the comparator receives a command from the intelligent drive electronics command latch corresponding to a command within the comparator command register, a fault is generated within the intelligent drive electronics command latch.
A gaming machine comprising:
- a housing;
- at least one user input coupled to the housing;
- a display coupled to the housing;
- and
- a control system, the control system comprising:
- a mass storage device;
- and
- a mass storage data protection system, the mass storage data protection system comprising:
- a mass storage device command latch;
- a timing circuit for timing signals between the mass storage device command latch and the mass storage device;
- a comparator between the mass storage device command latch and the timing circuit;
- and
- a comparator command register in communication with the comparator, the comparator command register including commands that generate a fault within the mass storage data protection system;
- wherein when the comparator receives a command from the mass storage device command latch corresponding to a command within the comparator command register, a fault is generated within the mass storage command latch.
A gaming machine comprising:
- a housing;
- at least one user input coupled to the housing;
- a display coupled to the housing;
- and
- a control system, the control system comprising:
- an intelligent drive electronics mass storage device;
- and
- a mass storage data protection system, the mass data protection system comprising:
- an intelligent drive electronics command latch;
- a timing circuit for timing signals between the intelligent drive electronics command latch and the intelligent drive electronics mass storage device, the timing circuit comprising a synchronizer and a reset generator;
- a comparator comprising a fixed command array and a user command array, the comparator being located between the intelligent drive electronics command latch and the timing circuit;
- a comparator command register in communication with the comparator, the comparator command register including commands that generate a fault within the mass storage data protection system;
- and
- a control and status register in communication with the comparator command register and the comparator, the control and status register being configured to at least partially control functioning of the mass storage data protection system;
- wherein when the comparator receives a command from the intelligent drive electronics command latch corresponding to a command within the comparator command register, a fault is generated within the intelligent drive electronics command latch.
