DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, the embodiment according to the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of the embodiment according to the present invention. FIG. 3 is a perspective view of an information process device of the embodiment. As shown in FIG. 3, although the information process device 1 is a gaming machine for business use, such gaming machine utilizes an operating system (OS) which is generally used in a personal computer on sale. And under an operation circumstances thereof, a game soft program stored in a hard disk mentioned later is operated.
And as shown in FIG. 1, in the information process device 1 according to the embodiment, a CPU 12, a ROM 13, a RAM 14, a bus 15, connectors 16, 17, a port 18, extended slots 19, 20 are provided on a mother board 11.
The CPU 12 controls the information process device 1 of the embodiment and executes various programs. Therefore, the CPU 12 corresponds to a control device.
And the ROM 13 is a nonvolatile memory in which various control programs are stored, such control programs being required when the information process device 1 of the embodiment is started to operate. The ROM 13 corresponds to a first memory device. And in the ROM 13, as shown in FIG. 1, a boot program storing area 13a for storing a boot program, a fault inspection program storing area 13b for storing a fault inspection program and a start program storing area 13c for storing a start program are formed.
Here, the boot program stored in the boot program storing area 13a, the fault inspection program stored in the fault inspection program storing area 13b and the start program stored in the start program storing area 13c will be described hereinafter.
Further, the RAM 14 is a memory for temporarily storing various data calculated when the CPU 12 executes programs.
The bus 15 is constructed from a PCI bus in which a bridge circuit for frequency change is formed, and becomes a common signal bus through which transmission and receipt of signals are conducted among the CPU 12, the ROM 13, the RAM 14, the connectors 16, 17, the port 18 and the extended slots 19, 20.
The connector 16 is a device to connect an output device 21 required when the game soft program is operated, to the mother board 11.
Here, the output device 21 connected to the connector 16 is constructed from a liquid crystal display (see the reference number 21 in FIG. 3) and a sound output device (not shown) such as a speaker. Instead of the liquid crystal display (see the reference number 21 in FIG. 3), a CRT display and the like may be used.
The connector 17 is a device to connect an input device required when the game soft program is operated, to the mother board 11. Here, the input device 22 is constructed from a control panel 22 (see FIG. 3) provided with a plurality of button switches (not shown). The input device 22 may include the other devices such as a keyboard, a mouse and the like, and according to contents of the game soft program, a joystick and the like may be connected to the connector 17. And in FIG. 1, although only one connector 17 is shown, if a plurality of input devices 22 are used, plural connectors 17 are provided respectively corresponding to each of the input devices 22.
And a hard disk 24 (HDD) is connected to the port 18 through a flat cable 23.
And in the hard disk 24 connected to the port 18, there are formed an operating system (OS) storing area 24a for storing the OS, an extended BIOS (Basic Input Output System) storing area 24b for storing an extended BIOS and an application storing area 24c for storing an application program which is the game soft program. Therefore, the hard disk 24 corresponds to a second memory device.
And the extended slot 19 is an insertion slot to connect a video board 25 to the mother board 11.
Here, the video board 25 connected to the mother board 11 through the extended slot 19 is a board having a graphics-accelerator to display figures and characters on the liquid crystal display (see the reference number 21 in FIG. 3) which is one of the output devices 21. The video board 25 can conduct performance with a resolution level and a graphics describing speed so that the operation of the game soft program in the information process device 1 of the embodiment can be properly executed.
And the extended slot 20 is an insertion slot to connect a sound board 26 to the mother board 11.
Here, the sound board 26 connected to the mother board 11 through the extended slot 20 is a board having a chip such as FM sound source and PCM sound source to output sounds from the speaker (not shown) which is one of the output devices 21. The sound board 26 can conduct performance so that the operation of the game soft program in the information process device 1 of the embodiment can be properly executed.
Next, with reference to a flowchart shown in FIG. 2, it will be described an operation executed when the information process device 1 according to the embodiment is started to operate. FIG. 2 is a flowchart of a start program executed when the information process device 1 is started to operate.
In the information process device 1 of the embodiment, when the device 1 is started to operate, the start program stored in the start program storing area 13c of the ROM 13 is executed by the CPU 12.
That is to say, as shown in FIG. 2, when the start program is executed, at first in S11, a boot program is executed.
Here, the boot program is a program stored in the boot program storing area 13a of the ROM 13, and based on the boot program, initialization of various devices including the extended BIOS (Basic Input Output System) in the hard disk 24 and the OS (Operating System) in the hard disk 24 is executed.
At that time, since the OS (Operating System) in the hard disk 24 is loaded in the RAM 14 and started to operate, the ROM 13 may be called as a boot ROM at this point of view.
Next, when procedure of the start program shifts to S12, the fault inspection program is executed.
Here, the fault inspection program is a program stored in the fault inspection program storing area 13b and through which a fault inspection in the hard disk 24 is executed. Concretely, according to the fault inspection program, it is inspected whether or not a damage occurs in the hard disk 24 or whether or not change or falsification of the program stored in the hard disk 24 is conducted.
Next, when procedure of the start program shifts to S13, it is determined whether or not a fault occurs in the hard disk 24. This determination is conducted based on an execution result of the fault inspection program obtained in S12.
At that time, if it is determined that the fault does not occur in the hard disk 24 (S13: NO), procedure shifts to S14, thereafter the application program stored in the hard disk 24 is loaded in the RAM 14 and execution of the application program is started. On the other hand, if it is determined that the fault occurs in the hard disk 24 (S13: YES), procedure shifts to S15 and error display is conducted on the liquid crystal display (see the reference number 21 in FIG. 3) which is one of the output devices 21.
As mentioned, in the information process device 1 according to the embodiment, as shown in FIG. 1, the fault inspection program is stored in the fault inspection program storing area 13b of the ROM 13 on the mother board 11 independently from the hard disk 24, thereby even if a fault occurs in the hard disk 24 which is inspected by the fault inspection program, it can be guaranteed that the fault inspection program properly operates.
And as shown in FIG. 3, the information process device 1 of the embodiment is used as the gaming machine for business use, and as shown in FIG. 2, the fault inspection program stored in the ROM 13 is executed at the time that the information process device 1 is started to operate and the fault inspection in the hard disk 24 is executed before games are started. Therefore, measures to avoid troubles during gaming can be taken beforehand, without giving displeasure to a player of the gaming machine for business use.
Here, the present invention is not limited to the embodiment mentioned in the above and various modifications can be conducted within the scope of the present invention.
For example, as shown in FIG. 3, although the information process device 1 of the embodiment is used as the gaming machine for business use, the information process device 1 may be adopted for a personal computer on sale. In this case, the keyboard, the mouse or the joystick may be utilized as the input device, instead of the control panel 22.
And in the information process device 1 of the embodiment, although the hard disk 24 is used as the second memory device, a flash memory in which contents can be changed and stored may be used. In this case, the fault inspection program inspects whether or not a fault occurs in the flash memory.
The present invention can be adopted for the fault inspection in the information process device.
