Abstract

PURPOSE:To improve flexibility or expanding property relating to the system constitution of peripheral devices for a computer system by providing the system with a device ID reading means, a deciding means and a driver task forming means. CONSTITUTION:The device ID reading means 11 inputs the device ID of each peripheral device from a channel and the deciding means 12 receives the device ID inputted by the means 11 and decides the validity of the device ID based upon a device ID control table 14. The driver task forming means 13 forms a driver task corresponding to the device ID of each peripheral device connected to the computer 1 on the basis of the decision of the validity of the device ID by the means 12. Consequently, the increment or removal of peripheral devices can be easily processed without applying specific system engineering such as a change in a system generation file, so that flexibility or expanding property relating to the system constitution of the peripheral devices for the computer system can be improved.

[Conventional technology]

Conventionally, the method for recognizing the system configuration when generating this type of system is to collect information about the system configuration of all peripheral devices connected to the computer (central processing unit, main T9 device, etc.) in the computer system during system generation. By registering it in a file, the system configuration of each peripheral device is recognized when the computer system is created (driver task for each peripheral device based on this recognition (task that controls the drive of peripheral devices when operating the computer system) ).

For this registration, a system engineer who is familiar with the entire system configuration of the hardware and software of the computer system in which the system is to be generated creates a system generation file in a form that is suitable for that computer system.

[Problem to be solved by the invention]

In the conventional method for recognizing the system configuration during system generation described above, a specific system engineer who is familiar with the system configuration of the computer system on which the system will be generated creates the system generation file in a form that is suitable for that computer system. Therefore, in order to add or remove peripheral devices from a computer system, it is necessary to involve a system engineer who is familiar with the computer system, and it is necessary for the system engineer to correct the system generation file. However, the disadvantage is that the system configuration of the computer system's peripheral devices is less flexible and expandable.

a determining means for determining the validity of the device ID; and a driver task generating means for generating a driver task corresponding to the device TD of each peripheral device connected to the computer based on the determination of the validity of the device ID by the determining means. have

[Effect]

In the system configuration recognition method during system generation of the present invention, the device ID reading means inputs the device ID of each peripheral device from the channel, and the determining means inputs the device ID of each peripheral device from the channel.

Referring to FIG. 2, the process of the device ID reading means 11 consists of a device ID input step 21 and a determining means activation step 22.

Referring to FIG. 3, the processing of the determining means 12 consists of a device ID management table registration determining step 31 and a driver task generating means activating step 32.

First, the device ID of each peripheral device (clock device 15, disk device 16, magnetic tape device 17, card reader device 18 or line printer device 19) connected to the computer 1 via a channel is input from each channel. Here, if no peripheral device is connected to the channel, a device ID indicating this (an ID consisting of a value other than the device ID indicating each peripheral device) is input from that channel (step 21).

Next, the determination means 12 in the computer 1 is activated (step 22).

The determination means 12 activated in step 22 performs the following processing (see FIG. 3).

First, it is determined whether the device 10 input in step 21 is registered in the device ID management table 14 in the computer 1 (whether or not a peripheral device is actually connected to the channel). (step 31).

In this determination, if the device ID is registered in the device ID management table 14, the driver task generation means 13 is activated to generate a driver task corresponding to the peripheral device related to the device ID (step 3).
