JPH04278616A - Initialization system for data input/output device - Google Patents

Abstract

PURPOSE:To shorten the starting time of an initialization system for a data input/output device by carrying out the diagnosis and the initialization of a computer main body in parallel with the initialization of the data input/output device. CONSTITUTION:In a data input/output device 4 which is connected to a computer main body 1 via an interface board 2, the device 4 itself carries out a group of commands produced from the board 2 at the start up of an initialization system for the device 4 concurrently with the application of a power supply. The carring-out results of those commands are preserved in the memory 6 of the device 4 and then reported when a command is issued from the board 2 for the initialization of the device 4.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for initializing a device, and more particularly to a method for initializing a data input/output device connected to a computer main body through an interface board.

0002

2. Description of the Related Art Conventionally, this type of device startup method has consisted of executing a group of commands issued from an interface board. FIG. 3 is an example of a timing chart when using this type of device initialization method. In the figure, the computer body first diagnoses and initializes various devices mounted inside the computer body, such as memory, at the same time as the power is turned on. After these are completed, a group of commands related to device initialization are issued via the interface board, the data input/output device receives these commands, actually executes them, and sends the execution results to the computer via the interface board. Notify. The data input/output device is initialized by this series of operations.

[Problems to be Solved by the Invention] Therefore, in the conventional device initialization method described above, in order to initialize the data input/output device, first, the various devices inside the computer main body are diagnosed and initialized. Computer diagnostics must be completed. Furthermore, the system cannot be started unless initialization of the data input/output device is completed. For this reason, there is a drawback that connecting a data input/output device increases the time required to start the system. The present invention
The purpose of this is to shorten the time required to start up the system.

According to the present invention, in an initialization method for a data input/output device connected to a computer main body via an interface board, the data input/output device receives a device initialization command. The additional processor has an additional processor for executing the command, and a memory for storing the execution result of the additional processor, the additional processor executes the device initialization command at the same time as the power is turned on, and the memory includes:
At the same time as accepting an issued command corresponding to the device initialization command issued from the interface board,
The execution result is transmitted via the interface board,
A device initialization method for a data input/output device characterized in that a response is sent to the computer main body is obtained. Further, according to the present invention, the data input/output device is characterized in that the additional processor has a determination unit that determines whether the issued command is a command that has already been executed among the device initialization commands. A device initialization method is obtained. Further, according to the present invention, when the issued command is an already executed command, the determination means transmits an execution result corresponding to the already executed command from the memory to the aforementioned interface board. A method for initializing a data input/output device characterized by sending a response to the computer main body is obtained. Further, according to the present invention, if the issued command is an unexecuted command that has not been executed yet, the determining means executes the unexecuted command,
The execution result is sent via the interface board,
A method for initializing a data input/output device characterized by sending a response to the computer main body is obtained. In other words, in the device initialization method of the present invention, in a data input/output device connected to a computer main body by an interface board, the data input/output device itself issues a group of commands when the system is started up by the interface board. The commands are simultaneously executed, the execution results are stored in a memory within the input/output device, and the execution results are returned immediately after receiving the command from the interface board.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the device initialization method of the present invention. The data input/output device 4 includes a computer main body 1, an interface board 2, and a cable 3.
connected via. Inside the data input/output device, there is an additional processor 5 for executing device initialization commands independently of commands from the interface board 2;
It has a memory 6 for storing the execution results. next,
The operation will be explained. In FIG. 2, in the device initialization method of the present invention, when the system is powered on, an additional processor 5 inside the input/output device is activated in parallel with diagnosis and initialization of various devices inside the computer. Perform memory diagnostics. After the diagnosis is completed, the additional processor 5 independently issues several types of commands that tend to be issued regarding device initialization to the device, and stores the execution results of these commands in the memory 6. After the diagnosis and initialization on the computer side are completed, the computer issues a group of commands related to device initialization via the interface board 2, but the additional processor 5 responds to these commands by processing commands that have already been executed. The execution result stored in the memory 6 is notified to the computer side without executing the command again, and if it is an unexecuted command, the execution result is notified to the computer side after being executed. As a result, the time required to start up the system can be reduced to the shortest time required to diagnose and initialize various devices installed inside the computer.

Effects of the Invention As explained above, in a data input/output device connected to a computer main body and an interface board, the data input/output device itself can issue a group of commands that the interface board issues at system startup. Executes at the same time as the power is turned on, saves the execution result in the memory of the input/output device, and returns the execution result immediately after receiving the command from the interface board, reducing the time required to start the system. This has the effect of
