Abstract

PURPOSE:To modify easily and correctly an operating system by interpreting contents of a modification parameter inputted through an input device and executing automatically processing of a program for modifying the table of the system. CONSTITUTION:Parameters used for deletion, addition, type modification, etc., corresponding to a peripheral device to be modified are inputted through a keyboard or file on a magnetic disk. When the inputted modification parameter is decided to be correct, contents of the modification parameter are interpreted, and the program used for modifying the table of the operating system is processed. In such a case, when an erroneous modification is executed, the significance of the parameter is decided, and the message that it is an erroneous input is outputted. Thus the operating system can be easily modified without an error.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is applicable to peripheral devices supported by an operating system (hereinafter abbreviated as O8), such as a line printer, a floppy disk device, a magnetic tape device, a typewriter, and a communication control device. The present invention relates to a method for changing the peripheral device support range of an operating system that allows the number and types of equipment, data way devices, character display devices, graphic display devices, process input/output devices, etc. to be easily changed without error.

[Conventional technology]

FIG. 3 is a flowchart showing the conventional changing method.

Following this flowchart, a method for changing the support range of peripheral devices in a conventional operating system will be explained as follows.

(1) Check which operating system table corresponds to the peripheral device you are trying to change.
i).

(2) Check which assembly parameter in the table corresponds to the peripheral device you want to change (3-2
).

(8) Change assemble parameters (5-5).

(4) Assemble the changed table of the operating system (5-4).

(6) Replace the changed table with the original table (
4-5).

(6) Check whether the changes are correct and whether the operating system correctly supports the changed peripherals (3-
6).

(7) If proper support is not possible, investigate the cause and make changes again (3-7).

[Problem that the invention seeks to solve]

Conventional modification methods follow the steps described above, so even if there is a simple change in the support range of a peripheral device, it requires complicated steps such as changing assembly parameters, assembling, replacing tables, and checking. However, there are problems in that it takes time to make the changes and is prone to errors.

This invention has been made to solve these problems, and provides a method for changing the range of peripheral equipment of 08 that can be easily and accurately changed without going through complicated procedures. The purpose is to

Means for Solving Problem C] The method for changing the peripheral device support range of O6 according to the present invention automatically executes the processing of a program that interprets change parameters input by an input means and changes the table of O8. It provides a means to do so.

[Effect]

By the above means, the table of O8 is automatically updated by 2.

〔Example〕

FIG. 1 is a block diagram conceptually showing each means for implementing the changing method of the present invention, in which (1) a changing parameter input means for inputting a parameter corresponding to a peripheral device to be changed; (2) is a program processing means for automatically changing the table of O8 by interpreting the parameters inputted by the change parameter input means (1); In this case, when a changed parameter is input, the significance of the parameter is determined, and a message indicating that the input is incorrect is output.

Based on the above configuration, the execution procedure of the changing method of the present invention will be described below with reference to the flowchart of FIG.

(1) Parameters corresponding to the peripheral device to be changed (delete,
(addition, type, etc.) (2-1). Input for this can be from a typewriter or from a file on a magnetic disk.

(2) It is determined whether the input change parameters are correct (2-2).

(8) If correct, processing of a program for interpreting the input change parameters and changing the OS table is performed (2-3).

(4) If you try to make an incorrect change, the significance of the input parameter will be determined at the time of inputting the change parameter, and a message will be output to the effect that the input was incorrect (2-4
).

In addition, although the above embodiment describes changing the table of O8, by applying this invention and changing tables other than O5, the scope of support for sub-transmission equipment of utility programs and semi-basic programs can also be covered. It is possible to change the table without reassembling it.

〔Effect of the invention〕

As described above, according to the present invention, for example, installation of peripheral devices, changes in types, changes in system configuration, etc. after delivery from the manufacturer to the customer can be easily and without error at the customer's site.
changes can be implemented.
