[Conventional technology]

In a conventional information processing device, an area for starting up the system is provided in the memo U (ROM), O8 is read in this area, and the IMPL function is read and started up using this O8. Generally, when starting up a system, only one of each function exists (multiple versions are not easily available), and if an error occurs in one of the functions when starting up, you can simply retry. If there is, and each function is destroyed, it will retry several times, display an error message, and stop.

[Problem to be solved by the invention]

The above-mentioned conventional startup method has the problem that when each function is destroyed, it is only necessary to retry several times, and the system cannot be started unless each function is corrected.

[Means to solve the problem]

The present invention is a startup control system for an information processing device, which includes an area (O8) on a hard disk (HD) for storing a plurality of operating systems of different versions, and an area (O8) for storing a plurality of operating systems with different versions. A plurality of reading function areas with different numbers, a plurality of initial microprogram load function areas (IMPL) with different versions, a plurality of sets of software storage areas, and versions corresponding to the operating system and each function. Priority information file ([
1]) and a version information file ([2]) that holds the version actually in use, and when an error occurs while the operating system and each of the functions are being executed after wiping at startup, Execute the program in which the error occurred by replacing it with the next version according to the priority information file, and retain the currently executed version in the version information file;
After the initial microprogram loading is completed, the content of the version number information file indicating which version was activated is displayed.

[For production]

In the present invention, each function used when starting up the information processing device has multiple versions on the hard disk.
Even if there is a destroyed function, the functions of other versions can be used to make it easier to start up the information processing device.

〔Example〕

FIG. 1 is an explanatory diagram of a priority information file according to the present invention. The priority information file is provided on the hard disk, and is a file in which the versions of each function are arranged in priority order, and is a file that specifies which version of the function to use at startup. As shown in the figure, the priority order of the OS loader function is 1st edition → 2nd edition → 3rd edition, and the O8 function is in the order of 2nd edition → 1st edition →
The order is 3rd edition, and the IMPL function is in the order of 3rd edition → 2nd edition → 1st edition.

Figure 2 is an explanatory diagram of the version information file.The version information file is also provided on the node disk and stores the version number in which each function was actually started. The version number at the time of activation of each function is displayed on the display when IMPL is normally completed. As shown, OS loader function, O8 function, IMPL machine,
All of the Noh plays are in one version.

FIG. 3 is an explanatory diagram of the contents of the hard disk (HD). The hard disk has O5 area and reading (OS loader)
It is divided into a functional area, an IMPL functional area, a software area, etc., and further includes a priority information file (■) and a version information file (■). Each area is indicated by a version number with priority.

FIG. 4 is an explanatory diagram of the reading function. When the power is turned on for the first time, the ROM loader (ROM> refers to the priority information file ■ and reads the highest priority version number file (1st version of the OS loader) in the hard disk reading function based on the priority of the OS loader. The version number is retained in the version information file■ by the number retention function and executed.The contents read by the reading function are memorized!The contents written to J MUM and read from the memory are stored in the priority information file■ again. is read into the O8 area based on the O8 priority, and the read contents are stored in the O8 area of the memory.

If an error occurs while executing the read function, refer to the priority information file ■ again, read the second priority version of the OS loader from the read function, and then update the version information file ■
Keep the version number and execute the same. The version number is rewritten to the version number information file using the rewrite function.

FIG. 5 is an explanatory diagram of the O8 execution function. The contents of O3 read from the memory are read into the IMPL function on the hard disk by referring to the priority information file ■, and the IMP
The contents read from the L function are stored in memory! Stored in the MPL function.

If an error occurs at this time, the next version is executed based on the priority information file (■) as in the case of the above-mentioned reading function.

FIG. 6 is an explanatory diagram of the IMPL function. The contents read from the memory are read into the software area of the hard disk, and the read contents are stored in the software area of the memory.

When IMPL completes normally, the version number of each function is displayed on the display using the startup version number display function.

FIG. 7 is a processing flowchart of the priority information file and version number information file. First, the version information file■
Refer to 1), and determine whether it is held in the version information file ■ (2). If it is not held, the version number with the highest priority of the priority information file ■ is held in the version information file ■3), and if it is held, the priority information file ■ is referred to (4). Next, determine whether the retained value of the version information file ■ and the read value of the priority information file ■ are the same (5), and if they are not the same, proceed to step (4).
If they are the same, they are stored in the version number information file ■ that has the next highest priority after the priority information file ■ (6). Then, go to read the retained version number on the hard disk (
7) and executed (8). If an error occurs at this time, the process returns to step (1).

〔Effect of the invention〕

As explained above, according to the present invention, the cause of a function failure when an information processing device is started up can be determined by displaying the startup version number, and by preparing multiple versions, the information processing device cannot be started up. This has the effect of solving this problem and making it easier to start up the information processing device.
