The computer is configured to perform processing such as IPL of the computer in response to the above.

[Industrial application field]

The present invention provides a control method for controlling a computer console. [Prior art and problems to be solved by the invention] A conventional computer console is connected to a service processor 16 as shown in FIG. , the service processor 16 was controlling the computer console 12a. Therefore, when the service processor 16 is operating as a control device for the computer console 12a, for example, even if there is an error handling request from the processing device, the error handling request may be made to wait, or the computer console may There is a problem in that even if there is a display request to 12a, the user is forced to wait for a long time until the error is recovered.

The present invention provides a built-in program in the computer main body to control the computer console and perform processing corresponding to instructions from the computer console, allowing the service processor to concentrate on monitoring the computer and quickly controlling B for the computer console. The purpose is to do so.

Means to solve CmH] Means for solving the problem will be explained with reference to FIG.

In FIG. 1, a computer console 2a is used to display and input information for various controls of the computer.

The built-in program 4 controls the total Xm operation console 2a and processes rPL etc. instructed from the computer operation console 2a.
This is a program installed inside the computer.

(Function) As shown in FIG. 1, the present invention provides a computer console 2a for displaying and inputting information for controlling various types of the total X81, and control of the computer console 2a and commands from the computer console 2a. A built-in program 4 is provided in the computer main body to perform processing such as IPL, and this built-in program 4 displays the status of the computer on the computer console 2a, and also displays the status of the computer on the computer console 2a.
Processing such as IPL of the computer main body is performed in response to instructions from a.

Therefore, by providing a built-in program 4 in the computer main body to control the computer console 2a and perform IPL processing in response to instructions from the computer console 2a, the conventional service processor can be dedicated to monitoring the computer. , it becomes possible to quickly control the computer console.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention will be explained in detail using FIGS. 1 and 2.

In FIG. 1, the main storage device (MSU>1 is a memory that stores programs, data, etc.); 1. A software area 1a that stores user programs; It is composed of a hardware area 1b that stores the following information.

The input/output device (Ilo) 2 is a terminal that performs input/output, such as a computer console 21 that gives control instructions and displays the status of the computer according to this embodiment.

If the transfer side m device (C) IP>3, it controls data input/output. 3a in this transfer ll1l'm device 3
represents control information provided for each input/output device (data transfer area instruction information of main storage device 1, etc.), 3b represents an address, and 3 represents control information provided for each input/output device.
c represents a count, and 3d represents an area selection bit (0: software area, 1: hardware area).

The built-in program 4 is related to this embodiment, and is a program provided in the computer main body that controls the computer console 2a and performs processing such as PL instructed from the computer console 2a.

A processing unit (CPU) 5 performs various processes.

53 in the processing unit 5 is a program status word (P
5b represents an execution control bit (〇--user program in progress, l--internal program in progress).

Next, the operation of the configuration shown in FIG. 1 will be explained in detail using FIG.

In FIG. 2, ■ is reset.

■ is set to built-in program mode (execution control bit 5
b to “1”).

(2) Executes built-in program 4. This means that the built-in program 4 is taken out from the hardware area 1b, set in the processing device 1, and executed.

■ Sets input/output device control information (area selection bit 3d in transfer control device 3 to 615 (quake hardware area)
).

(2) issues a transfer start instruction.

■ is in a waiting state.

■ In the case of ■, the transfer control device 3 performs data transfer.
This means that data is transferred from the main storage device 1 to the calculation 81 scratching console 2a according to this embodiment in the input/output device 2 in accordance with the area selection bit set to "1".

(2) Displays the transferred data on the computer console 2a, which is the input/output device 2, on the screen.

In (2), the operator issues, for example, an IPL instruction from the screen displayed in (2).

[Phase] corresponds to the IPL instruction of ■, and the computer operation console 2
An input/output interrupt request from a is generated in the transfer control device 3.

Then, control is passed to the built-in program 4 (3) to perform IPL processing.

O sets input/output control information (area selection focus 3d'0
” (-software area)).

■ Cancels built-in program mode (execution control bit 5)
b'"O").

[Phase] executes the user program.

As described above, with the reset as a trigger, the built-in program mode is set and the built-in program 4 is started, and the started built-in program 4 displays the screen on the computer console 2a via the transfer control device. I from the operator
By performing IPL processing in response to the input of PL instructions, canceling the built-in program mode after completion, and executing the normal user program, the conventional service processor is freed from the control of the computer console and can perform error processing, etc. It becomes possible to concentrate on the computer operation console and control the computer console quickly.

〔Effect of the invention〕

As explained above, according to the present invention, the built-in program 4 is provided in the computer main body to control the Ea operation console 2a and perform PL processing etc. in response to instructions from the computer operation console 2a. This allows the conventional service processor to be dedicated to monitoring the computer and quickly perform error processing, and also enables control of the computer console 2a to be performed quickly and independently of error processing. . This makes it possible to improve the reliability of the computer system.
