With a temporary operating unit being operating, a user provides a boot timing using a boot timing instructing unit. This causes a CPU to compute a boot preparation timing based on the boot timing, and store the boot timing and boot preparation timing to a boot timing memory. At this time, a timer begins a time-keeping operation. After that, the user turns off the power to the temporary operating unit. A boot preparation instructing unit determines whether or not the time being measured by the timer coincides with the boot preparation timing stored in the boot timing memory. When the time measured by the timer coincides with the boot preparation timing stored in the boot timing memory, the boot preparation instructing unit provides the CPU with a boot preparation instruction. This turns on the power to the temporary operating unit, and the CPU performs a boot preparation.

Disclosed is a system and method that uses digital signature technology to authenticate the contents of one or more manifests located on a storage device. Each manifest contains a list of file records, where each record contains the name of a file stored on the storage device, and a SHA1 hash value derived from the contents of the file. At boot time, the gaming machine first authenticates the contents of the manifest and then verifies the contents of the files using the SHA1 value stored in the manifest. Files are verified using the SHA1, as they are needed, during the boot up of the operating system and throughout normal operation. This method reduces the boot time of the gaming machine and eliminates the need to check digital signatures for each individual file or over the entire contents of a non-secure media.

When a personal computer system user carries out an OS shutdown, a BIOS does not turn off power, but reboots the system by a software reset to execute a POST, so that the state of the system immediately before starting the launch of the OS after completion of the POST is held in a volatile memory, and the system is shifted to a power saving mode. Subsequently, when the system is booted, the BIOS performs only restoration processing from the power saving mode while omitting the POST execution, and at once launches the OS, thereby shortening the system boot time by omitting the POST execution when the system is booted. Thus, POST processes are performed after the OS shutdown, a state that the POST has been completed after rebooting is held in the volatile memory, and then the system is placed into a state of power saving mode.
