Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for updating a network address in an information processing system, and more particularly to an expansion B even when the operating system is not present.
The present invention relates to a system and method for automatically updating network environment settings when a remote control function via a network is realized by an IOS or a management controller, and a recording medium recording a program.

[0002]

2. Description of the Related Art Conventionally, when an operating system is absent, an extended BIOS (basic input and output syste) is used.
m) or the environment in which the remote control function via the network by the management controller is realized, if the network settings are changed while the operating system is running, the network settings of the extended BIOS and the management controller are not changed, so the operating system ends. After that (shutdown), I had to manually start the individual network setting tools and change the network settings to the same as when the operating system was running.

In addition, changing the network settings when the operating system is operating is done by hardware (configuration).
It is necessary to customize the operating system in order to simultaneously reflect it in the extended BIOS and the management controller depending on the operating system, and it is difficult for the operating system in the open environment to deal with it.

[0004]

As described above, the conventional system has the following problems.

The first problem is that if the network settings are changed during operation of the operating system in an environment where the remote control function via the network is realized by the extended BIOS or the management controller when the operating system is absent, the extended BIOS and the Since the network settings of the management controller have not been changed, after the operating system is closed,
This means that remote control cannot be performed correctly unless you manually start the individual network setting tool and change the network settings to the same as when the operating system is running.

The reason is that in a remote console for remote control on a network, the operating system is operating and the operating system is absent.
This is because the network settings are different, which causes inconsistency in remote control.

The second problem is that in order to reflect the network setting change at the time of operating the operating system in the extended BIOS and the management controller at the same time,
This means that it is difficult to support an open environment operating system because the operating system needs to be customized.

The reason is that the specifications of the extended BIOS and the management controller depend on the hardware construction.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to change the network settings when the operating system operates.
Expanded BIOS automatically when the operating system is absent
An object of the present invention is to provide a system and a method and a recording medium that improve the operability by updating the network settings of the S and the management controller, and provide a seamless remote control function while the operating system is operating and when the operating system is absent.

Another object of the present invention is to provide a system, a method and a recording medium which can be easily mounted without depending on the type of the operating system by eliminating the customization of the core part of the operating system. To provide.

[0011]

According to the present invention to achieve the above object, in an information processing system connected on a network, a network packet sent to the information processing system while the operating system is operating is snooped. However, when the network address of the network layer given to the network adapter of the information processing system is changed, it is detected and an address change detection means for notifying an event, and when the network address is changed are described above. It is started by the event notification from the address change detection means, acquires the network settings on the operating system via the application interface provided by the operating system,
Expansion B that realizes remote control function using network adapter when operating system is absent
Network information storage means for converting to a format used in IOS or management controller and storing it in a non-volatile storage medium, and after being released from reset of the information processing system, it is started from the system BIOS and stored in the network information storage means. Obtained network information, and the network information is the extended BIOS and / or
Alternatively, if the network settings different from those already set in the management controller, the expansion BIOS
S and / or network information updating means for automatically updating the network settings of the management controller.

When this happens, it is automatically activated by an event notification from the address change detection means (14), and the operating system provides network settings (for example, IP address, default gateway address, subnet mask, etc.) on the operating system. It is acquired via the application interface, and when the operating system is absent, it is converted to the format used by the extended BIOS (5) and the management controller (6) that provide the remote control function by using the network adapter (4), and the nonvolatile Network information storage means (11) to be stored in a storage medium (21), and after the reset of the information processing system is released, it is automatically activated from the system BIOS and acquires the network settings stored in the network information storage means (11). However, if the network settings different from those already set in the extended BIOS (5) and / or the management controller (6), the extended BIOS (5) is set.
And / or network information updating means (31) for automatically updating the network settings already set in the management controller (6).

The address change detecting means (14) detects the packet addressed to the physical address of the network adapter received by the network adapter driver (15) during the operation of the operating system, so that the network layer protocol control software of the operating system operates. When a network address used (for example, an IP address) is changed, it is detected, and an event is notified to the network information storage means (11). Therefore, no customization of the network layer protocol control software of the operating system is required.

The network information storage means (11) is activated by the event notification from the address change detection means (14), and the operating system sets the network settings of the operating system (for example, IP address, default gateway address, subnet mask, etc.). After acquiring via the standard application interface provided, convert it to the format used by the extended BIOS (5) or management controller (6) that provides remote control function using the network adapter (4) when the operating system is absent, Stored in a non-volatile storage medium (2).

The network information updating means (31) is automatically activated from the system BIOS when the reset of the information processing system is released, and the network information storage means (11) acquires the network settings stored in the non-volatile storage medium (2). Then, the network setting set in the expansion BIOS or the management controller is compared, and if different, the network setting set in the expansion BIOS or the management controller is automatically updated.

According to the embodiment of the present invention having such a configuration, since the matching of the network address is guaranteed when the operating system is operating and when the operating system is absent, seamless remote control is possible.
