Patent ID: 8622822

Claim:
A gaming machine comprising: a gaming board having a memory card mounted on the gaming board, the gaming board including: a first CPU; and a first memory for storing an authentication program for authenticating game information stored in the memory card; and a motherboard connected to the gaming board via a signal transmission unit including a PCI Bus and an IDE Bus, the motherboard including; a second CPU; and a second memory for storing the game information stored in the memory card, wherein after startup of each of the gaming board and the motherboard, the first CPU of the gaming board transmits a reset signal to the second CPU via the PCI Bus such that the second CPU remains in a reset state and readout of the game information by the second CPU is suspended until receipt of a reset release signal, after transmission of the reset signal to the second CPU, the first CPU reads the authentication program stored in the first memory and performs an authentication process with respect to the game information stored in the memory card before the game information is loaded onto the motherboard, where no abnormalities are detected during the authentication process, the first CPU transmits the reset release signal as an authentication complete signal to the second CPU of the motherboard via the PCI Bus, upon receipt of the reset release signal, the second CPU reads the gaming information from the memory card via the IDE Bus, loads the game information onto the second memory, and carries out gaming operation in accordance with the game information stored in the second memory, wherein the first and second CPUs have simultaneous access to the PCI Bus without the use of a BUS switching device.
