DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bios (BIO)
More specifically, the present invention relates to a computer system, a BIOS management method, and a BIOS management program for automatically performing, via a network, a recovery process at the time of rewriting failure or the like in S).

[0002]

2. Description of the Related Art BIOS (Basic Input / Outp)
ut System, a basic input / output system) is a program for controlling various devices connected to a computer. The OS does not directly control the device, but controls it by calling the BIOS function. In many cases, BIOS is stored in a ROM (Read Only Memory) and cannot be rewritten, but recently, an electrically rewritable EEPROM (Electrically Erasa
ble Programmable ROM) and flash memory (Fl
Storing bios in an ash memory) often makes it possible to upgrade it.

For example, Japanese Patent Application Laid-Open No. Hei 10-187454 proposes a technique for rewriting the BIOS of a client-side computer from a host computer via a network.

[0004] Hereinafter, such a rewritable memory for recording BIOS will be referred to as a BIOS ROM, and BIOS data recorded in the BIOS ROM will be referred to as BIOS data.

[0005] Further, in such a computer device capable of rewriting the BIOS ROM, the BIOS RO
If rewriting of M fails or other computer error occurs, abnormal data may be recorded in the BIOS ROM. In such a case, a failure occurs such that the BIOS does not function properly and the system cannot start up. Therefore, troublesome work is required to recover the failure.

[0006] As shown in FIG.
M is a boot block (Boot-Blo
ck) and a section called a non-boot block (Non Boot-Block) that can be rewritten for adding functions or correcting defects. Therefore, even if the rewriting of the non-boot block fails, the BIOS can initialize the necessary minimum device only by the data of the boot block that has not been rewritten. Then, the illegal data stored in the non-boot block is read by a software for rewriting BIOS (or hardware) to read a floppy (registered trademark) disk or CD on which the correct BIOS data is recorded, and rewrite correctly. And the system was restored.

Is provided.

FIG. 6 is a diagram showing the configuration inside the BIOS ROM 10. As shown in FIG.

The BIOS is basically provided with a boot block (Boot-Block) 12 for executing the minimum necessary device initialization processing without being rewritten, and is provided with various additional functions to add functions and correct defects. A non-boot block (Non Boot-Block) 13 that performs rewriting in the case of, for example, is provided. Rewriting BIOS usually means rewriting this non-boot block 13. Further, when abnormal data is recorded in the BIOS ROM 10 such as when rewriting of BIOS fails, the BIOS cannot start the system because the monitored device 100 cannot operate normally. Can not.

Subsequently, the bios data is checked (step 203). In the present embodiment, the BIOS process is performed by the BIOS itself. In this method, a program for executing a check process is installed in advance in the BIOS ROM 10, and the program is read to control the operation of the monitoring target device 100, thereby executing the process of checking the BIOS data. Here, the bios data check process can be executed by a method such as checking a checksum.

If an abnormality is detected in the BIOS data 11, a request is made to the service processor 20 to restore the BIOS data (step 206). Then, in response to the BIOS data recovery request, the service processor 20 requests the server 200 to transmit BIOS data (step 207).

In the server 200, the requested bios data is transmitted from the bios data providing unit 50 to the monitored device 100 in response to the bios data request (step 208).

Then, the service processor 20 uses the correct BIOS data transmitted from the server 200 to
The BIOS ROM 10 is rewritten (step 209).
As a result, the BIOS is correctly rewritten and the recovery is completed (step 210).

If necessary, the service processor 2
By instructing a restart with 0, and restarting the system, the processing can be performed normally thereafter.

The operation of sending the bios data request 72 from the monitored device 100 to the server 200 will be described.

First, the power of the monitored device 100 is turned on.
(Step 301). When the power is turned on, the BIOS starts an initialization process based on the data stored in the boot block 12 (step 302). After the BIOS boot block 12, the BIOS calculates the checksum of the entire data in the BIOS ROM 10 and checks whether the BIOS data 11 is correct (step 303).

If it is determined that there is no problem in the check, normal processing (processing of the non-boot block portion) is continued, and the system of the monitored device 100 is started (step 305). If the BIOS determines that there is a problem, the BIOS issues a BIOS recovery request 70 to the service processor 20 to restore the BIOS ROM 10.
Is issued (step 306).

The service processor 20 receiving the BIOS restoration request 70 issues a BIOS data request 71 to the network device 30 to request the server 200 for BIOS data via the network (step 307). Upon receiving the BIOS data request 71 from the service processor 20, the network device 30 sends a BIOS data request 72 to the server 200.
Is issued (step 308).

Next, referring to the flowchart of FIG.
The server 200 receives the bios data request 72 from the bios data providing unit 50 and
The operation of transmitting the BIOS data 75 to the server will be described.

First, the network device 40 on the server 200 receives the BIOS data request 72 issued from the monitored device 100 (step 401). Bios data providing unit 50 that monitors monitoring target device 100
Is the monitoring target device 100 on the network device 40.
When it is detected that the BIOS data request 72 has come, the BIOS data request 73 is accepted (step 402). Upon receiving the bios data request 73, the bios data providing unit 50 transmits the bios data 51 managed by itself to the network device 40 to transmit the bios data 51 to the monitored device 100 via the network. Send (Step 40)
3). Bios data 7 from bios data providing unit 50
The network device 40 that has received 4 transmits the bios data 75 to the monitoring target device 100 (step 404).

Here, the bios data transmitted from the bios data providing unit 50 to the device to be monitored 100 is normal bios data that allows the device to be monitored 100 to operate normally. 30
In the check of the checksum and the like in No. 3, it is also detected that the check is normal.

Here, a plurality of types of monitoring target devices 1
To 00 (also for various versions of bios data)
In order to respond to the provision from the server 200, the server 20
In the storage unit of No. 0, a plurality of types of bios data are recorded, and the bios data providing unit 50 searches for bios data corresponding to the monitoring target device that has requested the bios data, acquires and transmits the bios data, and the like. Embodiments are also possible.

Finally, with reference to the flowchart of FIG. 5, the operation of the service processor 20 from receiving the BIOS data 75 from the server 200 to restoring the BIOS ROM 10 on the monitored device 100 will be described.

First, the network device 30 on the monitored device 100 receives the BIOS data 75 sent from the server 200 (Step 501). When the service processor 20 detects that the BIOS data 75 has been sent to the network device 30, it retrieves the BIOS data 76 (step 502). Service processor 20 receiving BIOS data 76
Executes the BIOS ROM rewriting 77 to rewrite the data stored in the BIOS ROM 10 based on the data (step 503). BIOS ROM
When the rewriting 77 is completed normally, the BIOS ROM 10
Is restored, and the system starts up normally (step 504).

After that, the service processor 20
The system may be restarted, and the process may return to step 301 and subsequent steps. In this case, since the BIOS has been normally restored, no problem is detected in the BIOS data check (step 304), and normal processing can be continued (step 305).

Next, another embodiment of the present embodiment will be described.

In the first embodiment, the monitored device 100 is provided with the service processor 20, and the service processor 20 is provided with the bios data 11.
This is a method that has a function for executing the acquisition and rewriting processing of the data. However, the present invention is not limited to this method.

For example, it is conceivable to add a function provided in the service processor 20 in the first embodiment, such as a function of performing a network connection process on the BIOS itself. As a result, the service processor 2
The same processing as that of the first embodiment can be realized in a computer having no 0.

Conventionally, the boot block 12 of the BIOS ROM 10 contains only the necessary minimum device initialization processing such as a floppy disk or a network. Therefore, as an example of this, this boot block 12
In addition, a method of adding a BIOS recovery process following the process in the conventional boot block can be considered.

That is, the bios of this embodiment is
It is determined whether the data in the BIOS ROM 10 is correct. If it is determined that the BIOS ROM 10 needs to be restored, the network device is initialized and a network connection is established.
It receives the data of 0 and restores the BIOS ROM 10.

In this case, it is required that the function newly added to the BIOS is operated without being affected by the abnormality generated in the BIOS data. This is because the boot block 12 which does not normally rewrite the data is required. Since this function is added, it is possible to prevent the operation of the recovery process from being affected due to a failure in rewriting BIOS or the like.

As described above, in the embodiment in which the bios has the function of the recovery processing, it is not necessary to provide the service processor 20, and the same effect as that of the first embodiment can be obtained, and the cost can be reduced. Can be reduced.

As still another embodiment, a processor (BIOS management processor) having a recovery processing function is newly incorporated in a computer in addition to the method of incorporating a recovery processing function in the service processor 20 provided in the computer. Thus, a method of setting the monitoring target device 100 is also possible.

In the first embodiment,
Although the process of checking whether or not there is an abnormality in the BIOS data is executed by BIOS itself, it is also possible to execute this process on the service processor 20 side.

The computer system according to each of the above-described embodiments has a function of detecting a BIOS abnormality provided in the service processor 20 or the like, a function of requesting BIOS data via a network, a function of rewriting the BIOS ROM 10 with correct data, and the like. In addition to realizing other functions as hardware, the computer program having each function can be realized by being loaded into the memory of the monitored device 100 which is a computer processing device. This computer program
It is stored on a magnetic disk, semiconductor memory, or other recording medium 90. Then, the functions described above are realized by being loaded from the recording medium 90 to the monitored device 100 and controlling the operation of the monitored device 100. For example, the computer program is stored in the service processor 20 or the BIOS ROM 10 by firmware (Fi
rmware).

Although the present invention has been described with reference to the preferred embodiments and examples, the present invention is not necessarily limited to the above-described embodiments and examples, and various modifications may be made within the scope of the technical idea. Modifications can be made.

First, in the present invention, the bios RO
Even when abnormal data is recorded in M, correct bios data can be obtained from the server via the network, and all data can be restored by automatic processing.

Therefore, even if an abnormality occurs in the BIOS of a computer installed at a remote location, the computer is completely restored by automatic processing, so that there is no need for the administrator to go directly to the installation location of the computer.

Second, if a computer is equipped with a service processor, the BIOS automatic recovery function of the present invention can be easily installed without requiring any special hardware. . The automatic BIOS recovery function of the present invention can be realized by simply incorporating a program for executing the processing of the present invention into a service processor provided in such a computer device. Also, the server can be easily provided with a function of receiving a BIOS data request and returning the requested BIOS data.
