In FIG. 3, reference numeral 1 denotes a keyboard for inputting data, and 2 denotes a system circuit incorporated in the main body of the computer, which is configured to perform arithmetic processing based on a signal input from the keyboard 1. I have. 3
Is a ROM in which a BIOS program and the like provided in the system circuit 2 are stored, 4 is a display unit for displaying a result of arithmetic processing performed by the system circuit 2, and the like.
Reference numeral 5 denotes a hard disk, which is configured to write and store a table of contents of various programs such as applications and system programs. Reference numeral 6 denotes a peripheral device such as a floppy disk device or a CD-ROM drive device.

In the computer, when the power is turned on, startup operations such as device diagnosis, reading of a device driver, and initialization are performed, and the startup operation of the system is completed. After the start-up operation is completed, the software of the application selected by operating the keyboard or mouse is read and various operations are performed. When a power-off operation is performed, the power of the personal computer is turned off after a preset power-off process is performed.

As described above, the computer is configured. Next, a control method when the power is turned off according to the present invention will be described with reference to the flowchart shown in FIG.

When the power-off operation is performed, a power-off process is started (step A). After step A is performed, diagnosis such as determination of the type of a device such as a connected peripheral device is performed, and an operation of creating a table of contents A as a result of the diagnosis is performed (step B). Such an operation is, for example, as shown in FIG.
When it is diagnosed that the device 2 is absent and the device 3 is diagnosed, the index 101 and the table of contents are added. In addition, as shown in FIG. Is indexed as Index011.

Next, an operation of reading the table of contents B stored in the hard disk 5 is performed (step C). After such an operation is performed, a comparison operation between the table of contents A and the table of contents B is performed (step D). In step D, when the table of contents A and B do not match (the table of contents B is
In this case, the table of contents A and the system program corresponding to the device of the table of contents are stored in the hard disk 5 (step E). When the operation in step E is completed, processing for terminating all programs is performed, and the system is terminated (step F). Thereafter, a power-off operation is performed (step G).

In step D, if the table of contents A and B do not match, the above-described processing operation is performed. If the table of contents A and B match, the table of contents and the system program stored in the hard disk 5 are stored. Need not be rewritten, the process proceeds to step F to perform a power-off operation.

As described above, the operation when the power is turned off is performed. Next, the control operation when the power is turned on will be described with reference to the flowchart shown in FIG.

Although the system is configured to start when the power of the computer is turned on, such an operation starts with an operation of reading the BIOS (step H).
After the step H is performed, a diagnosis such as presence / absence of connection of a peripheral device and a type determination of a device such as the connected peripheral device is performed, and an operation of creating a table of contents A as a result of the diagnosis is performed (step S1). I). Such an operation is performed in the same manner as when the power is turned off as described above, for example, as shown in FIG. 4, when the device 1 is diagnosed as being present, the device 2 is not determined, and the device 3 is diagnosed as being indexed with Index 101. As shown in FIG. 5, the device 1 is not present, the device 2 is present, and the device 3 is diagnosed as present.
nddex011 will be added to the table of contents.

Next, an operation of reading the table of contents B stored in the hard disk 5 is performed (step J). After such an operation is performed, a comparison operation between the table of contents A and the table of contents B is performed (step K). In step K, when the table of contents A and B do not match (the table of contents B
In this case, the initialization is performed (step M) after the device driver is read (step L), which is a startup operation by a normal computer.

When the initialization process is performed in step M, an operation for determining whether or not there is a next device is performed (step N). When it is determined in step N that there is a device, the above-described steps L and L are performed. Step M
And the operation of repeating Step N is performed. If it is determined in step N that there is no next device, the start-up of the system is completed (step O).

In step K, the hard disk 5
If the table of contents B and the table of contents A stored in
A reading operation of the system program stored corresponding to the table of contents B stored in the hard disk 5 is performed (step P). When such an operation is performed, the process proceeds to step O, and the start-up of the system is completed. That is, the system start-up operation is completed by reading the system program without performing the three-step operation of reading the device driver (step L), initializing (step M), and determining whether there is a next device (step N). Will do.

Although the system program is stored in the table in the hard disk in the present embodiment, it is also possible to reduce the load on the hard disk by compressing and storing it.

[0019]

According to the present invention, when a power-off operation is performed in a state where the system program has been started, the system program is stored in the hard disk with a table of contents. The start-up operation can be promptly performed by reading the system program.

After the device is diagnosed and a table of contents is created when the power of the computer is turned on, the table of contents is compared with the table of contents stored in the hard disk, and when the table of contents is matched, the table of contents is stored in the hard disk. Since the system program is read out, the startup time from power-on to system startup can be reduced.

According to the present invention, since the system software program to be stored in the hard disk is compressed and stored, the writing capacity of the hard disk can be reduced.
