[0007] Furthermore, the present invention provides an information processing device that includes an information processing device that has an I/O management table in its main memory that is referenced by the OS to recognize the system configuration, and a peripheral control device that is connected to the information processing device. In the processing system, the peripheral control device has notification means for notifying the information processing device that the peripheral control device has been incorporated into the system when the peripheral control device is connected to the information processing device, and the information processing device includes: determining means for determining that a peripheral control device has been incorporated into the system based on the information notified from the notifying means; and updating means for updating the system configuration on the I/O management table based on the information from the determining means. and a notification interface for connecting the notification means and the determination means between the information processing device and the peripheral control device.

Furthermore, the present invention provides an information processing apparatus comprising an information processing apparatus having an I/O management table in the main memory that the OS refers to in order to recognize the system configuration, and a peripheral control apparatus connected to the information processing apparatus. A method for updating an I/O management table in a processing system, the peripheral control device comprising:
When the peripheral control device is connected to the information processing device, the information processing device is notified that the peripheral control device has been incorporated into the system, and the information processing device is configured to connect the peripheral control device to the system based on the information notified from the peripheral control device. The system configuration on the I/O management table is updated.

[0009]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an information processing system according to an embodiment of the present invention. This information processing system includes an information processing device 101 and a peripheral control device 106 (only one is shown in the figure).

The information processing device 101 has an I/O management table 102 that the OS refers to in order to recognize the system configuration.
is stored in the main memory.

The information processing device 101 further includes a determining means 104 for determining whether the peripheral control device 106 has been incorporated into the system, and an I/O based on information from the determining means 104.
The update means 103 updates the system configuration on the O management table 102.

On the other hand, the peripheral control device 106 has notification means 105 for notifying that the peripheral control device 106 has been incorporated into the system.

Information processing device 101 and peripheral control device 106
In between, a conventional I/O interface 108,1
In addition to 09, a notification interface 107 is newly provided between the notification means 105 and the determination means 104.

Next, the operation of this embodiment will be explained.

The peripheral control device 106 is the information processing device 101
When connected to the notification means 105 of the peripheral control device 106
informs the information processing device 10 via the notification interface 107 that the peripheral control device 106 has been incorporated into the system.
The judgment means 104 of No. 1 is notified.

[0017] Upon receiving this notification, the determining means 104:
The update means 103 is informed that the peripheral control device 106 has been incorporated into the system.

The updating means 103 updates the system configuration by updating the system configuration I/O management table 102 referenced by the OS.

As described above, according to the information processing system of this embodiment, when the peripheral control device 106 is incorporated into the system, the I/O management table is automatically updated. To change the system configuration, based on the updated data,
There is no need to perform system initialization processing again.

[0020]

[Effects of the Invention] As explained above, the present invention enables the peripheral control device to be incorporated into the system by connecting the peripheral control device to the information processing device, so that there is a high degree of freedom in the system configuration. It has the effect of becoming.
